New and Noteworthy Archives

A new system property, streambase.decouple.operator.log-level, enables operator and adapter logging levels to be set independently of the system logging level. Its default is false, which keeps the old behavior whereby operators and adapters use the more verbose setting of the component's or the system log-level property value. When set to true, operator and adapter logging verbosity can be set lower than the system logging level.

In the .NET Client API, the Timestamp class has been changed to better handle conversions to and from .NET DateTime objects. Specific changes are:

The Use Formatted Timestamps checkbox has been deprecated.

A new Timestamp option has been added as a drop-down list box, with choices Prepend, Append and None (default). Use this control to optionally add a timestamp to the beginning or end of each CSV row.

Adding timestamps enables applications to record data from any input or output stream in a top level application or exposed, in a format suitable for playback. Use the timestamped CSV files for feed simulations to play back streams you recorded in real time.

While an application is running, you can tell sbadmin to capture CSV files from input or output streams by issuing commands such as:

For more information, see CSV File Writer Output Adapter.

A new option on the Adapter Properties tab of the TREP-RT Subscribing adapter, Include AttribInfo In All Updates, adds AttribInfo into all update and refresh messages sent to its subscribers. Receiving this data causes the publishing adapter to include AttribInfo in all messages.

The Tuple Properties tab has two new options:

The Trading Components DB-Rapid venue can now output missing depth tiers as zero price items as part of the DepthOfBook message when an item becomes stale. This functionality is disabled by default. Add the parameter OutputMissingTiersAsZeroPriceItems to the instance and set it to true to enable this feature.

When looking up fields, the Thomson Reuters Schema Designer now automatically detects fields with fractional pricing, and adds both the double and string fields to the available fields users can select to create a schema. For example, if the BID field indicates a price of 88 3/32, the field list will now contain a BID field of type double and also a BID_as_string field of type string. The Thomson Reuters subscribe adapter now also automatically maps any field in the schema with an "_as_string" suffix to the string representation of that field.

The Exegy library has been updated to version 3.1.11. You must upgrade your installation's Exegy library to this version in order to use this adapter.

A new property, Include Subscribe Pass-Thru Field, has been added. When enabled, the Subscribe stream schema is expected to include a field of any type named PassThru, which is is passed through to the Equities, PriceBook, and Commodities output ports.

A new property, Include Basket Pass-Thru Field, has been added. When enabled, the Basket stream schema is expected to include a field of any type named PassThru, which is is passed through to the BasketUpdates and BasketNav output ports.

For other Exegy input adapter updates, see Fixed in 7.2.15 release notes.

The Wombat Publishing adapter can now send messages using any of the ARRAY types, as well as the VECTOR_MSG, and VECTOR_STRING type. Types are mapped as follows:

The XML to Tuple and Tuple to XML Operator Sample group has been reorganized as five sample applications, four of which have been redesigned:

The two -attribute variants illustrate generating and parsing XML attributes. The two -datatype variants illustrate using fields with a variety of StreamBase data types, including primitive types, lists, and nested tuples. xml2tuple-fixml.sbapp demonstrates how to parse a FIXML message.

The two tuple2xml samples now have two input streams each, one which runs through a map operator to supply default values for any tuple fields containing null, and a second which leaves the user's input unchanged. The three xml2tuple sample applications can now be fed from either new canned XML file read by the file reader adapter or from a user-supplied XML string through an alternate input stream (which is used by the automated tests as well). A note on each sample sbapp canvas describes what the sample does and how the canned data is supplied.

The embedded Web Reader input adapter now supports HTTP POST as well as HTTP GET. Two new examples were added to the Web Reader Samples illustrating how to handle POST and SOAP requests.

The Trading Components Framework now provides extra data for swaps and forwards. To support this change, the FX handlers of the Trading Components Framework have an additional schema field, SettlDateFar, for the settlement date for the far leg of swaps.

The following enhancements were made:

StreamBase now has a Deutsche Bank AutobahnFX Classic FIX adapter, with accompanying market data and execution handlers. The Deutsche Bank AutobahnFX Rapid FIX adapter and handler, which was named Deutsche Bank FIX in prior StreamBase releases, is now called Deutsche Bank AutobahnFX Rapid FIX Adapter to distinguish it from the new Deutsche Bank Classic FIX adapter and handlers.

The Log output adapter now has an option to override the Log Level you set for the adapter on a per-tuple basis. In the Log Adapter Properties pane, use the Log Level Override Field to specify the name of a field in a logged stream that contains log level information. The field can contain any of the following values: Error, Warn, Info, Debug, or Trace. Any other value, including null, causes the adapter use the configured log level for that tuple.

The File Reader input adapter reads a text file and emits a tuple with a string field containing the entire contents of the file. The adapter can be configured to read a file at start-up or in response to the receipt of a tuple on its control input port.

The TREP-RT RMDS subscribe adapter now has a Download Service(s) property that lets users restrict the set of Thomson Reuters services from which data dictionaries are downloaded. In addition, multiple instances of the adapter within a StreamBase application can now share downloaded and locally-loaded data dictionaries.

A new command, ListInstruments, has been added to the FAST-based adapters, BM&FBovespa UMDF Input adapter and CME Market Data FIX/FAST adapter. The ListInstruments command will cause the adapter to list all the instruments available on a given channel by emitting one tuple per defined instrument on the Instrument Definitions output port.

The RFA/Java library, rfa.jar, used by TREP adapters has been upgraded to version 7.2.1.

The Gain GTX FIX adapter allows a StreamBase application to connect to the trading infrastructure provided by GAIN Capital, and to exchange FIX messages with it.

The File Reader input adapter reads a text file and emits a tuple with a string field containing the entire contents of the file. The adapter can be configured to read a file at start-up or in response to the receipt of a tuple on its control input port.

The new Bloomberg Server API input adapter is an embedded adapter that can connect to a Bloomberg Server API process to subscribe and get data from the process.

The new Bloomberg B-Pipe input adapter is an embedded adapter that can connect to a Bloomberg B-Pipe process to subscribe and get data from the process.

The new Deutsche Bank AutobahnFX FIX adapter allows a StreamBase application to connect to the Deutsche Bank AutobahnFX trading infrastructure and to exchange FIX messages with it.

Additional properties to support XML parsing were added to the IBM WebSphere MQ input adapter and Wall Street Systems input adapter. In addition, the existing and new XML parsing properties have been placed in a new XML Parsing tab. The properties on the new tab include:

Thomson Reuters Enterprise Platform for Real-Time (TREP-RT) subscribing adapter has two new properties:

The Saxo Bank FIX market data handler now has mass quote support.

The sbadmin operator now has username and password properties for use with local connections. See the sbadmin reference page for more information.

The tuple-to-XML operator now has an Attribute Fields property that can be used to specify a comma-delimited list of fully-qualified tuple field names that should generate XML attributes rather than sub-elements. For example, if the XML generated by the operator for a given input tuple is:

<Top><s>This value comes from tuple field Top.s of type string</s></Top>

Adding Top.s to the Attribute Fields property would result in the following XML:

<Top s="This value comes from tuple field Top.s of type string"></Top>

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_45. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. See Supported Configurations.

In previous releases, the option to have an adapter or operator start with an application was chosen with a checkbox. This option is now a field with allowed values yes, no, or a module parameter that resolves to either true or false.

Adapters in a application that have Start with application set to false now have a visual indicator () on the adapter icon. Input adapters display the decorator on the bottom-right corner of the adapter icon; output adapters display the decorator on the top-left corner of the adapter icon.

You can create a named schema from an existing schema directly from the application view by right-clicking any arc and selecting Refactor → Extract Named Schema.

Event Flow application streams that are exposed for enqueue or dequeue are now indicated by a decoration on the stream's icon:

The output from the sbprofile command now includes the number of tuples delivered for each input/output stream.

The Feed Simulation Data File Options dialog now has a vertical scroll bar to enable use on small displays.

Copying and pasting multiple tuples with the Copy as JSON option now formats multiple tuples as:

[tuple1,tuple2,...,tuplen]

In previous releases, multiple tuples were separated with carriage returns.

The drop-down menu near the upper right corner of the Variables view of StreamBase Studio's debug perspective gives you the option to hide null values in tuples fields, list elements, and dynamic variables. See Viewing Tuple Contents for more information.

The Barclays BARX FIX adapter allows a StreamBase application to connect to the BARX trading infrastructure provided by Barclays and exchange FIX messages with it.

The 29West LBM Subscribing Input Adapter now has the following new features:

To use the LBM Adapters from StreamBase 7.2.11 and above, ensure you have LBM version 6.0 or above. The StreamBase installation kit includes version 6.0 of the UMS_6.0_jdk1.5.0_12.jar JAR file.

The CSV File Reader Input adapter and CSV Socket Reader Input adapter have a new property, Lenient Parsing, whose default value is true.

The Trading Components framework now supports market data and execution handlers for UBS.

When a container, A, is added to a running StreamBase Server, and that container has a connection to the system.control stream, container A no longer receives the STARTING tuple on the control stream. However, other control-connected containers in the same Server instance do receive the STARTING tuple for container A. See The Container Subsystem.

This release increments the Python language support in StreamBase in two ways:

See Creating StreamBase Python Clients for details.

This release includes a change to the rolling file name feature used by the CSV File Writer and XML File Writer adapters, and by the sbprofile command. Before this change, the rolled-over file's name represented the beginning of the roll period for weekly rolling, but represented the end of the roll period for daily or hourly rolling. After this change, rolled-over file names represent the beginning of the roll period for all rollover intervals.

The CSV Socket Reader Input adapter was updated to provide a server mode where the adapter listens on a specified port for incoming connections. In addition, when acting as a client, the adapter now attempts to reconnect if connections fail, using a specified wait period between reconnection attempts. The adapter also has new properties for specifying how to handle incomplete records, and whether to log incomplete record events.

The CSV File Reader Input adapter was updated to provide new properties on its Parsing Options tab for specifying how to handle incomplete records, and whether to log incomplete record events.

The sample for the CSV File Reader adapter was simplified for clarity. See CSV File Reader Input Adapter Sample.

The tojson() function was updated to accept an optional second argument, boolean verbosity. By default, or with the second argument expressed as true, the function returns a string formatted as a JSON object, as defined on http://www.json.org. With the second argument expressed as false, the function returns a JSON array.

The new Loop sample in the Applications category of Studio's Load StreamBase Samples dialog demonstrates a looping arc in a simple EventFlow application.

The Saxo Bank FIX adapter allows a StreamBase application to connect to the trading infrastructure provided by Saxo Bank, and to exchange FIX messages with it.

The FIX Output adapter and all adapters that inherit from the FIX Output adapter were updated with the ability to track acknowledgement of the receipt of sent messages. This feature is described in Requesting Outgoing Message Send Confirmation on the FIX Output Adapter page.

The data dictionary for the Trading Technologies adapter was updated to implement version 7.8.1 of the Trading Technologies FIX specification.

The Thomson Reuters TREP-RT Subscribing Input adapter was updated such that CLOSED events, including access denied errors, are now logged at the INFO level, in addition to being sent to the adapter's event port.

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_37. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

The StreamBase documentation for release 7.2.10 included the following updates independent of the above changes:

When you drag the Java Operator icon from the Palette View to the canvas, the resulting dialog contains a new global Java operator, the Runtime Schema Cast operator. This operator transforms its input schema to its specified output schema, at the same time expanding capture fields in the input schema to the subfields of each capture field. Capture field expansion is configured in the operator to be performed with either Flatten or Nest transform strategies.

The new operator is used inside modules that use capture fields in their input schema or table definitions, when the module can be used generically to handle several similar incoming schemas, but also has special processing for one or more schema types, as described in the Runtime Schema Cast Operator's page in the Authoring Guide. The new operator has a sample, described in Runtime Schema Cast Operator Sample.

In the Properties view for a Query Table data construct, when pre-loading a Query Table with the Initial Contents tab, you can now use tab-separated value (TSV) files or TSV lines typed directly in the Initial Contents tab. TSV format joins the CSV and JSON formats already supported. See Properties: Initial Contents Tab on the Query Table Data Construct's page.

In the Simulation Streams section of the Feed Simulation Editor, you can now copy schemas from named schemas as well as from streams in modules or interfaces in your Studio workspace. The Copy Existing Stream button was relabeled Copy from Stream/Named Schema.

The EventFlow Debugger gained two new features in this release:

The expression language gained a new function, getAllHostIPs(), which returns as a list(string) all the non-loopback IP addresses assigned to the machine on which StreamBase Server is running.

The input and output adapters for IBM WebSphere MQ and Wall Street Systems were updated to use IBM MQ version 7.0. This update changed the JAR files you must obtain from IBM to use both adapter pairs. The list of required JAR files was updated in the documentation for both adapters and their samples.

The Alpha Trading Systems EMAPI Order Entry adapter was updated to support the EMAPI 5.1 specification.

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_35. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

The StreamBase documentation for release 7.2.8 included the following updates independent of the above changes:

When you select and right-click one or more tuples in the Application Input or Application Output views, the context menu now offers some new options designed to accelerate the creation of StreamBase JUnit tests.

The new Save-As options generate fragments that can be pasted into an existing StreamBase JUnit test's Java file. The options are described in Copy Tuples to Clipboard on the Application Output page.

In addition to the above, this release introduces a new feature that generates an entire working StreamBase JUnit Java test file from scratch, based on selected tuples in the Application Input and/or Application Output views. A new button now appears in the toolbar of the Application Output view:

and in the toolbar of the Application Input view:

Click either button to run the New StreamBase Unit Test Class wizard. This is the same wizard described in the Test/Debug Guide, with additions to specify the set of tuples on which to base the test, and to specify which tuple maker class to use.

Use the Selected Tuples option when you pre-select one or more tuple rows in the Application Input and/or Application Output views before starting the wizard. The Example code option generates a generic test as before.

The Tuple Maker Class drop-down selects CSV or JSON single quote tuple maker types. The JSON tuple maker is the default, but it does not handle tuples that contain slashes or double quotes in field values. Use the CSV tuple maker for those cases.

Starting with this release, you can select a Module Reference to a flexible module, right-click, and from the context menu, select View Module with Overridden Schemas. Like using F3, this opens an EventFlow Editor canvas showing the referenced module. However, there are important differences compared to opening with F3:

While this feature is not an interactive debugging aid, it can nevertheless help you understand how a flexible module is actually used at runtime. See EventFlow Editor Read-Only Canvas for more on this feature.

In the Project Properties dialog, the Module Search Path panel has a new feature. Below the Resolved Module Search Path grid, look for the new Generate configuration file snippet controls. These are links that create a fragment of a server configuration file ready for including into your project's top-level server configuration file, as described in Module Search Path Configuration File Snippets.

The same links appear in the Resource Search Path panel, in this case creating fragment files containing operator resource search path links. See Resource Search Path Configuration File Snippets.

StreamBase release 7.1.11 enhanced the X O keyboard shortcut so that if the most recently added component is a Module Reference, the automatically added output ports receive the names of the corresponding output streams in the referenced module.

This release adds the X I (ex eye) shortcut, which operates on input ports. For any component selected or recently added to the canvas, X I adds input streams to that component's input port or ports. If the newly added component is a Module Reference, the newly added input streams take on the names of the corresponding input streams in the referenced module.

Finally, this release adds the X A shortcut, which performs both X I and X O actions on the selected or most recently added component. This is especially useful right after adding an adapter or a Module Reference to the canvas.

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_33. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

This release includes the new Web Reader adapter that reads from a specified URL using HTTP GET requests and emits the page contents in a string field of its Data output port. The adapter can be configured to read a web page on demand when receiving a tuple on its control input port, or to periodically poll the specified web page. The adapter is described in Web Reader Input Adapter in the Adapters Guide.

This adapter is especially useful for reading web pages that emit a pure XML structure containing ongoing market trade data. This adapter's sample demonstrates reading such a page, and uses the XML to Tuple operator to parse the received XML data. See Web Reader Input Adapter Sample in the Samples Guide.

The XML to Tuple operator was updated to eliminate unnecessary console messages when parsing XML comments and repeated elements that map to a list. The operator's sample was updated to include a new application that parses a complex, hierarchical XML input string, using a FIXML message as the example. See XML to Tuple and Tuple to XML Operator Sample.

The data dictionary for the Trading Technologies adapter was updated to implement version 7.8.0 of the Trading Technologies FIX specification.

The IBM WebSphere MQ Input adapter now has an Include JMS Correlation ID Field property, which is only activated when the Include Metadata Field is selected. If enabled, the adapter includes a JMSCorrelationID subfield in the schema metadata field that holds the JMS correlation ID received with the message.

The StreamBase documentation for release 7.2.7 included the following updates independent of the above changes:

Starting with this release, StreamBase Studio and StreamBase Server are supported using Oracle JDK 7, update 4 or later, as an alternative to the JDK 6 shipped with StreamBase. To use JDK 7, follow the instructions on Using an External JDK. That page also describes how to use JDK 7's G1 garbage collector.

To better support StreamBase projects saved in version control systems, this release provides a small behavior change when first opening EventFlow module files that do not have an associated layout file. In previous releases, under these circumstances, Studio would interpolate the layout information and save it back to the EventFlow file (to the .sbapp file). Now, Studio always creates a separate layout file (an .sblayout file) to contain the layout information.

Studio still honors the preference setting as before that determines whether or not to create a separate layout file when creating a new .sbapp file. The new behavior only affects the case when no matching .sblayout file exists when first opening an existing .sbapp file.

You can now select any two operators of the same type in the same EventFlow module, right-click and select Compare These Components from the context menu. This opens a side-by-side dialog that compares the properties of the selected operators. See Comparing Selected Components, a new page in the Authoring Guide.

If you place a trigger string in the text of a Note or in a Description field for an EventFlow component, the text of that note or field is placed in the Eclipse Tasks view as a task reminder note. Use this feature to place reminder notes about features of your application that need further development. The recognized trigger strings are TODO, FIXME, and XXX. See Using the Tasks View for more on this feature.

The icons for Query Tables and for Input and output stream on the EventFlow Editor canvas now show an overlay decoration to indicate two independent states. Streams that are used to update dynamic variables are shown with (x)= in the upper right of the icon. Streams and Query Tables that are implementations of an interface are shown with a boxed uppercase I in the lower right corner of the icon's tile.

The icons for input and output streams now show an overlay decoration on their upper back corner to indicate that this stream initiates a container connection to another stream by means of the Container connection field in the Advanced tab of the stream's Properties view.

Streams on the other side of the connection in the receiving container are not decorated. Decorations are not applied for container connections specified to connect at runtime in a deployment file, in a Studio launch configuration, in StreamBase Manager, or from the command line with the sbadmin command.

Studio has provided the X O keyboard shortcut for several releases: drag an operator to the canvas, then press X O, and the output port of the newly dropped component acquires an arc connecting to an output stream automatically named OutputStream. If the newly placed operator has more than one port, X O adds output streams to all ports. This keyboard shortcut performs the same function as right-clicking an output port and selecting Add Output Stream to Port.

This release adds special behavior to both the Add Output Stream context menu and the X O keyboard shortcut if the component dragged to the canvas is a module from the Package Explorer view. In this case, X O adds output streams as before, but it now names them the same as the corresponding streams in the referenced module.

When defining a Run, Debug, or Trace Configuration in Studio, and adding entries to the Environment tab, Studio has for many releases allowed the use of Eclipse variables to compose environment variables for a configuration. Starting with this release, the list of variables now includes ${sb_home}, which is defined as the absolute file system path of the StreamBase installation directory as currently set in Studio's Preferences dialog.

Studio was updated such that newly created Delta Stream icons are not subject to renaming, since Delta Streams must use their default names as created.

The Java and C++ Client Libraries were extended with new methods that allow you to specify a strategy (FLATTEN or NEST) for handling capture fields in streams accessed from a client application or from a custom embedded operator or adapter. The new APIs are described on a new page in the API Guide, Client Access to Capture Fields.

The Capture Fields for Generic Data Store sample now includes a Java operator that demonstrates the use of the new capture field strategy API methods.

The sbprofile command, in addition to the -c option, now has a -b outfile option. Use -b to specify that the generated output file is to be compressed with the bzip2 protocol, with the .bz2 extension added to the output file.

This release adds Vertica 5.1 to the versions supported by StreamBase. For Vertica 5.1 native connectivity, the StreamBase adapter requires the Vertica 4.1 Java client library (vertica_4.1.xx.jdk_5.jar). Vertica 5.1 is also supported for access through the Vertica JDBC driver.

The RSS Reader Input adapter was updated with three new properties: Use Proxy, Proxy Host, and Proxy Port. Use these properties to specify a proxy server through which the RSS feed of interest is visible.

The StreamBase documentation for release 7.2.6 included the following updates independent of the above changes:

This release extends and updates the Smart Merge feature for server configuration files, supplementing the support for standard XInclude with a new configuration file element <sb-include>, described in Using Modular Configuration Files in the Administration Guide.

This release also introduces a new utility, sbconfutil, that allows you to see as a single file the merged results of multiple inclusions. See the sbconfutil reference page, which is also available as a man page on UNIX platforms.

In previous releases, Query Tables were not subject to typechecking, because the schema of incoming data could not be anything other than the Query Table's schema. However, since release 7.2.0, Query Tables can have an initial load optionally specified. As of this release, individual Query Tables now participate in typechecking to make sure the table schema of associated Query operators are the same as the schema used for initial loading, if used.

In the Edit Dimension dialog that you open from the Dimensions tab of the Aggregate operator, the default size of the Open, Emit, and Close fields is now wider, and you can now use the F2 key to open a secondary Edit Expression pop-up dialog for each field. When you save a long expression in one or more of these fields, the dialog resizes when reopened to show as much of the expression in each field as possible.

In the Operation tab of the Query operator, the wording of the first entry in the If no row is found drop-down list was changed for clarity to Leave table unmodified, output nothing. The behavior of the operator is unchanged.

Releases 7.1.8 and 7.2.3 added the StreamBase → Clean File context menu option to clean and rebuild individual EventFlow modules. Starting with this release, you can use the Ctrl+Alt+T keyboard shortcut to initiate the same action.

The Open StreamBase Resource dialog, invoked with Ctrl+Shift+R, or from the Open StreamBase Resource toolbar button (), now includes any StreamBase LiveView™ configuration files with the .lvconf extension in the current Studio workspace.

Studio's Help menu now shows the Eclipse-standard Eclipse Marketplace entry, which gives Studio easier and more direct access to hundreds of third-party Eclipse plug-ins.

This release supports new Apache Flume External Input and Output adapters, which allow a StreamBase application to integrate with Apache Flume 1.1 or later as either a Flume sink or source. The Flume adapters are separately licensed, and, like other external adapters, this adapter pair has a separate installer downloadable from your usual StreamBase download site. See Apache Flume External Adapters for details.

The Feed Simulation Input adapter was updated to accept maxtuples and maxtime commands on its control input port, and to optionally report LASTNUMTUPLES actions on its status output port. See Feed Simulation Input Adapter for details.

A new property was added to the BM&FBovespa UMDF Input adapter and to the CME Market Data FIX/FAST adapter, which specifies a preference for the method to be used for recovering missing incoming FAST messages. The options are between either the TCP-based Historical FIX channel or the UDP-based Market FAST channel.

The Exegy Input adapter and Exegy Monitoring adapter were rewritten to take advantage of the Exegy Java API, resulting in the following changes:

The TableAccessor interface in the com.streambase.sb.operator package now has a size() method that returns the number of rows in the table.

For release 7.2.5 and later, StreamBase Studio is based on Eclipse 3.7.2. When installing Studio in the form of plug-ins for a separate copy of Eclipse, you must start with Eclipse 3.6 or 3.7. Eclipse 3.5 is no longer supported for that purpose. See Studio Eclipse Update Site.

For most purposes, StreamBase releases are well distinguished by their release numbers in three-position major.minor.maintenance format, such as 7.2.5. On rare occasions, you may need to report the fourth position build number. Starting with this release, the full four-position release number is visible from the command prompt in STREAMBASE_HOME/doc/VERSION.txt and in the documentation at the top of the Release Notes page.

The StreamBase documentation for release 7.2.5 included the following updates independent of the above changes:

In the Properties view for a Query Table, in the Table Settings tab, the radio button control to select In memory or On disk table types was replaced with a drop-down list. You can now write over the default selections to specify the name of a parameter in the form ${param-name}. This allows you to pass in the choice of table type at runtime. For example, if you set the Type control to the parameter ${tabletype}, then the module that contains the table must contain or be passed a parameter of that name with either disk or memory as its value.

StreamBase installation DVD-ROMs and installation download sites now include both 32-bit and 64-bit versions of the StreamBase .NET Redistributables kits. Unlike the 32-bit version, the 64-bit version includes only the required StreamBase assemblies and supporting DLLs, and does not attempt to install a .NET framework. Install either kit, but not both, to support running StreamBase .NET client programs on machines without StreamBase installed. See Redistributing the .NET Client Library.

When using the EventFlow Debugger, the red square Terminate button in the Debug view's toolbar () now performs the same clean shutdown of the running StreamBase Server instance as the Stop button () in the main Studio toolbar. In previous releases, the Debug view Terminate button stopped the debug session, then halted the Server instance without a clean shutdown.

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_31. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

This release includes the Bloomberg Tradebook FX FIX adapter that allows a StreamBase application to connect to the trading infrastructure provided by Bloomberg Tradebook FX, and to exchange FIX messages with it. See Bloomberg Tradebook FX FIX Adapter.

The CME FIX/FAST adapter allows a StreamBase application to connect to CME's Market Data Platform to receive market data in the form of FIX/FAST messages. The adapter uses the high-speed, low-latency StreamBaseFIX engine to decode the incoming FAST messages. The adapter is described in CME Market Data Platform FIX/FAST Input Adapter and has a sample.

The EventFlow Debugger saw continuing improvements for 7.2.3, including the following features:

The default JVM memory settings were updated as of release 7.2.2 and are now documented in this release in Java VM Memory Settings and Garbage Collection Policy Settings in the Administration Guide. The following points summarize the changes:

The Query.sbapp sample in the Operators sample group was extended to add samples of Write-Update and Delete operations. See Query Operator Sample.

The implicit conversion of int to string for expression values in the Query operator, announced as deprecated in release 7.2.0, was removed as of this release for consistency with other StreamBase operators.

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_30. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

The sbd command has a new command-line option, --debug or -d. Use either option to prepare a run of StreamBase Server to accept remote debugging connections. Notice that the -d option was used in previous releases to enable intermediate stream dequeuing; that feature is now enabled with --intermediate-stream-dequeue.

The --debug option accepts one or more comma-separated key-value pairs as arguments that override default settings. For example, sbd --debug suspend=y causes the server to start and immediately suspend execution, awaiting connection from the debugger. See the sbd reference page for further details on overriding default settings.

StreamBase Studio has long supported attaching to a remotely running instance of StreamBase Server, as described in Attaching to a Running Application. Starting with this release, you can attach to a remote server in debug mode and use the EventFlow Debugger to debug both StreamBase and custom Java code. Follow the steps described in Attaching to a Running Server in Debug Mode.

The Thomson Reuters Enterprise Platform for Real-Time Subscribing Input Adapter was updated to support a new property, Disable Market Price View Requests. When enabled while using the Market Price message model, the OMM View Request optimization for subscribing to a selected set of fields is disabled.

This release adds the Feed Simulation Input adapter, which uses Feed Simulation configuration files to define the adapter's output ports and their schemas, and to determine what data is emitted from each adapter port. Feed simulation configuration files are created with the StreamBase Feed Simulation Editor as usual, and the same files can be used interchangeably with this Feed Simulation adapter and with the command line tool, sbfeedsim. Any data sources, generation methods, and emission rates definable with the Feed Simulation Editor can be used with this adapter. The adapter has a sample, described in Feed Simulation Input Adapter Sample.

In previous releases, the sbunit command was delivered as a 32-bit executable on both 32-bit and 64-bit Windows, which meant that StreamBase JUnit tests ran in a 32-bit JVM. Starting with release 7.2.1, the 64-bit Windows installation of StreamBase includes both 32-bit and 64-bit sbunit commands, so that 64-bit Studio now launches 64-bit StreamBase JUnit tests by default.

The PATH environment variable passed to StreamBase Server when launched from Studio now includes the streambase-install-dir/bin directory appropriate for the platform. This feature only affects the ability to locate StreamBase utility commands when run from within StreamBase Server by means of an External Process operator or the SB Admin operator. For Linux, a Studio-launched Server's PATH includes /opt/streambase/bin. For 32-bit Windows and for a 32-bit Server launched from 64-bit Windows, the Studio-launched Server PATH includes streambase-install-dir\bin. For 64-bit Windows, the PATH includes streambase-install-dir\bin64;streambase-install-dir\bin.

In addition, previous releases incorrectly appended the StreamBase home directory itself, streambase-install-dir, to the Studio-launched Server PATH. This was removed from the Studio-launched Server PATH as of this release, which may result in changed behavior if your application came to rely on this undocumented feature in some way.

This release adds the getClientIP() function.

In previous releases, the StreamBaseMonitor class always included the monitored details for each running operator in the monitored Server. Starting with 7.2.1, you must use the enableOperatorDetail() method to obtain operator details.

When a container, A, is added to a running StreamBase Server, and that container has a connection to the system.control stream, container A no longer receives the STARTING tuple on the control stream. However, other control-connected containers in the same Server instance do receive the STARTING tuple for container A. See The Container Subsystem.

The tojson() function was updated to accept an optional second argument, boolean verbosity. By default, or with the second argument expressed as true, the function returns a string formatted as a JSON object, as defined on http://www.json.org. With the second argument expressed as false, the function returns a JSON array.

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_35. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

The StreamBase documentation for release 7.1.12 included the following updates independent of the above changes:

To better support StreamBase projects saved in version control systems, this release provides a small behavior change when first opening EventFlow module files that do not have an associated layout file. In previous releases, under these circumstances, Studio would interpolate the layout information and save it back to the EventFlow file (to the .sbapp file). Now, Studio always creates a separate layout file (an .sblayout file) to contain the layout information.

Studio still honors the preference setting as before that determines whether or not to create a separate layout file when creating a new .sbapp file. The new behavior only affects the case when no matching .sblayout file exists when first opening an existing .sbapp file.

Studio has provided the X O keyboard shortcut for several releases: drag an operator to the canvas, then press X O, and the output port of the newly dropped component acquires an arc connecting to an output stream automatically named OutputStream. If the newly placed operator has more than one port, X O adds output streams to all ports. This keyboard shortcut performs the same function as right-clicking an output port and selecting Add Output Stream to Port.

This release adds special behavior to both the Add Output Stream context menu and the X O keyboard shortcut if the component dragged to the canvas is a module from the Package Explorer view. In this case, X O adds output streams as before, but it now names them the same as the corresponding streams in the referenced module.

The XML to Tuple operator was updated to eliminate unnecessary console messages when parsing XML comments and repeated elements that map to a list. The operator's sample was updated to include a new application that parses a complex, hierarchical XML input string, using a FIXML message as the example. See XML to Tuple and Tuple to XML Operator Sample.

The RSS Reader Input adapter was updated with three new properties: Use Proxy, Proxy Host, and Proxy Port. Use these properties to specify a proxy server through which the RSS feed of interest is visible.

The EBS adapter was updated with a new data dictionary that supports both EBS Ai FIX 1.3 and 1.4.

The StreamBase documentation for release 7.1.11 included the following updates independent of the above changes:

This release introduces two new Palette operators, the XML to Tuple Converter and the Tuple to XML Converter. These operators are found by dragging the Java Operators icon from the Palette to the canvas, selecting one of the new operators from the list, then pressing Enter.

As their names imply, the new operators are inverses of each other. In fact, the best way to learn the XML syntax expected by the XML to Tuple Converter is to run the same schema through the Tuple to XML Converter.

The XML to Tuple Converter takes a single string field as input, with the string expected to contain a well-formed, XML-encoded message. The operator emits one tuple for each input XML message. The operator has a standard Edit Schema tab in its Properties view in which you specify the schema of the tuple you want to extract from the input XML string. The tuple's schema does not need to describe the entire XML string, which lets you extract only the elements of interest, as long as the schema preserves the hierarchy of the incoming XML. The operator provides a method to extract attributes of incoming XML elements.

The Tuple to XML operator converts StreamBase tuples to XML-encoded messages. Each field in the operator's input port schema populates an element or attribute in the resulting XML message. Each tuple enqueued to the operator results in a single XML message emitted on its output port.

The new operators share a new sample that provides examples that convert both element-only XML and XML that has elements with attributes. The sample EventFlow modules use named schemas to define elements that may include attributes. See XML to Tuple and Tuple to XML Operator Sample.

The behavior of the Union operator was changed slightly as follows: when dragging an arc to a Union operator, the standard create-new-port behavior is only triggered when the Union operator has no available input ports.

StreamBase Studio now places entries in the Problems view when it detects semantic errors in the server configuration file that affect the current project's typechecking environment. For example, referring a custom function to a Java operator that does not exist now shows a Problems view entry with the name of the function that could not be configured. Resolve such errors early in the development process.

The Log Asynchronously property for new Log adapters is now enabled by default.

The IBM WebSphere MQ subscribe (input) and publish (output) adapters were updated to provide support for topics as well as queues. For the input adapter, the following new properties control the use of topics: Use Topics, Default Topic, Allow Dynamic Topics, and Max Topic Count. See IBM WebSphere MQ Input Adapter.

The output adapter has the following new properties: Use Topics, Default Topic, and Topic Field Name. See IBM WebSphere MQ Output Adapter.

The Thomson Reuters TREP-RT Subscribing Input adapter was updated to add a new property, Derive Update Type from Market Feed Data, which is active when the current message model is Market Feed (RMDS 5). When enabled, this property causes the adapter to derive the specific update message type from the raw market feed data. This might be used when the useMarketfeedUpdateType property in the RFA configuration file does not function as expected in certain Thomson Reuters environments. See Thomson Reuters Enterprise Platform for Real-Time Subscribing Input Adapter.

This release extends and updates the Smart Merge feature for server configuration files, supplementing the support for standard XInclude with a new configuration file element <sb-include>, described in Using Modular Configuration Files in the Administration Guide.

This release also introduces a new utility, sbconfutil, which allows you to see as a single file the merged results of multiple inclusions. See the sbconfutil reference page, which is also available as a man page on UNIX platforms.

StreamBase installation DVD-ROMs and installation download sites now include both 32-bit and 64-bit versions of the StreamBase .NET Redistributables kits. Unlike the 32-bit version, the 64-bit version includes only the required StreamBase assemblies and supporting DLLs, and does not attempt to install a .NET framework. Install either kit, but not both, to support running StreamBase .NET client programs on machines without StreamBase installed. See Redistributing the .NET Client Library.

In the Edit Dimension dialog that you open from the Dimensions tab of the Aggregate operator, the default size of the Open, Emit, and Close fields is now wider, and you can now use the F2 key to open a secondary Edit Expression pop-up dialog for each field. When you save a long expression in one or more of these fields, the dialog resizes when reopened to show as much of the expression in each field as possible.

This release includes the Bloomberg Tradebook FX FIX adapter that allows a StreamBase application to connect to the trading infrastructure provided by Bloomberg Tradebook FX, and to exchange FIX messages with it. See Bloomberg Tradebook FX FIX Adapter.

The CME Market Data FIX/FAST adapter allows a StreamBase application to connect to CME's Market Data Platform to receive market data in the form of FIX/FAST messages. The adapter uses the high-speed, low-latency StreamBaseFIX engine to decode the incoming FAST messages. The adapter is described in CME Market Data Platform FIX/FAST Input Adapter and has a sample.

This release supports new Apache Flume External Input and Output adapters, which allow a StreamBase application to integrate with Apache Flume 1.1 or later as either a Flume sink or source. The Flume adapters are separately licensed and, like other external adapters, this adapter pair has a separate installer downloadable from your usual download site. See Apache Flume External Adapters for details.

A new property was added to the BM&FBovespa UMDF Input adapter and to the CME Market Data FIX/FAST adapter, which specifies a preference for the method to be used for recovering missing incoming FAST messages. The options are between either the TCP-based Historical FIX channel or the UDP-based Market FAST channel.

The Exegy Input adapter and Exegy Monitoring adapter were rewritten to take advantage of the Exegy Java API, resulting in the following changes:

Release 7.1.8 added the StreamBase → Clean File context menu option to clean and rebuild individual EventFlow modules. Starting with this release, you can use the Ctrl+Alt+T keyboard shortcut to initiate the same action.

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_31. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

The C++ Client Library was augmented with two methods added to the sb::ClientSettings class:

The associated setting controls the maximum number of tuples stored in the client's internal dequeuer queue before applying back pressure on the connected StreamBase Server. See the Doxygen documentation for details.

For most purposes, StreamBase releases are well distinguished by their release numbers in three-position major.minor.maintenance format, such as 7.1.9. On rare occasions, you may need to report the fourth position build number. Starting with this release, the full four-position release number is visible from the command prompt in STREAMBASE_HOME/doc/VERSION.txt and in the documentation at the top of the Release Notes page.

The StreamBase documentation for release 7.1.9 included the following updates independent of the above changes:

Release 7.0 added the ability to use the XInclude standard to break server configuration files into reusable pieces. This release extends that support with a new smart merge feature that allows you to XInclude an entire server configuration file into another, including the root element, with any duplicated elements merged together into one element in the resolved file. Child elements that do not conflict are simply merged, while child elements with conflicting definitions are resolved, usually with the last definition winning. See the revamped Using Modular Configuration Files page for details.

This release includes a preview of the module signature feature, which is expected to be added to a future release. To enable, use Window → Preferences, open the StreamBase Studio → Typechecking panel, and select the check box labeled Enable module signature change analysis during builds. This directs Studio to store a hash of the signature for all modules and all intermediate stream schemas in the metadata of each module file. This in turn allows Studio to build dependent modules only when the hash value changes, which means only when the module itself has changed. For large, complex applications with many modules, this setting speeds up building of the application as a whole.

In the Properties view for a Query Table, in the Table Settings tab, the radio button control to select In memory or On disk table types was replaced with a drop-down list whose third entry is a blank line. Select the blank line to enter the name of a parameter in the form ${param-name}, which allows you to specify the choice of table type at runtime. For example, if you set the Type control to the parameter ${tabletype}, then the module that contains the table must contain or be passed a parameter of that name with either disk or memory as its value.

This release introduces several new features in StreamBase Studio that help you detect and eliminate any schemas or constants imported into a module that are not currently being used by that module. Eliminating unused imports speeds up the build times for large StreamBase applications. These features are discussed in a new page in the Authoring Guide, Minimizing Module Imports.

In large StreamBase applications with many module references, building the entire application can take a noticeable amount of time. Starting with this release, you can specify building of one module at a time instead of building the entire application. To do this, select an individual EventFlow module's name in the Package Explorer view, right-click, and select StreamBase → Clean File. This option does not appear for StreamSQL modules.

In previous releases, if you changed anything in a project's server configuration file, Studio would re-typecheck the build environment for the entire project. As of this release, Studio detects the type of changes made to server configuration files, and only rebuilds when necessary. For example, a change in XML comments no longer rebuilds the project.

A new preference setting, Ignore label widths during auto-layout was added to the EventFlow Rendering page of StreamBase Studio preferences. This setting is disabled by default; enable it to direct Studio to ignore the width of component labels when running Layout Application (Ctrl+L), which allows long labels to overlap on the canvas. For the most compact canvas display for large modules, enable this option and disable the slanted arcs preference.

The sb-config command was updated to provide better support on UNIX for directories named with spaces. The Windows version of the command was not changed, and on UNIX, the Java-related command options were not changed. See the sb-config reference page for details.

The Exegy input adapter now has an Include Receipt Nanotime property, which, when enabled, adds an XC_ADAPTER_INITIAL_NANOTIME field to the Equities, Commodities, and PriceBook output ports. See Exegy Input Adapter.

The Thomson Reuters Enterprise Platform for Real-Time Subscribing Input Adapter was updated to support a new property, Disable Market Price View Requests. When enabled while using the Market Price message model, the OMM View Request optimization for subscribing to a selected set of fields is disabled.

The Oracle JDK installed for private use by StreamBase was updated to version 1.6.0_30. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

This release includes two adapters contributed by Thomson Reuters for connecting to the Thomson Reuters Enterprise Platform for Velocity Analytics. These are the Velocity Analytics Broadcast Server Input Adapter and the Velocity Analytics UTSS Output Adapter. Both adapters are illustrated in a new set of samples, described in Thomson Reuters Velocity Analytics Samples.

Release 7.1.6.2 included a new adapter for the Exegy Ticker Plant data feed. The adapter is described in Exegy Input Adapter in the Adapters Guide, and has a sample, described in Exegy Adapter Sample in the Samples Guide.

In addition, there is a new Exegy Monitoring adapter described in Exegy Monitoring Adapter. The Exegy sample includes modules that illustrate both the Exegy Input and Exegy Monitoring adapters.

Certain typecheck errors in a server configuration file can result in the entire file considered invalid and discarded for a particular run of StreamBase Server. The handling of these errors was changed as of this release.

In previous releases, an error such as a failure to locate the files that support a custom function class would result in logging a warning to the Error Log or Problems view. To ensure that errors of this type are not missed (since they are often the root cause of other application typecheck errors), Studio now shows these errors as an error against the server configuration file itself.

The PATH environment variable passed to StreamBase Server when launched from Studio now includes the streambase-install-dir/bin directory appropriate for the platform. This feature only affects the ability to locate StreamBase utility commands when run from within StreamBase Server by means of an External Process operator or the SB Admin operator. For Linux, a Studio-launched Server's PATH includes /opt/streambase/bin. For 32-bit Windows and for a 32-bit Server launched from 64-bit Windows, the Studio-launched Server PATH includes streambase-install-dir\bin. For 64-bit Windows, the PATH includes streambase-install-dir\bin64;streambase-install-dir\bin.

As of this release, there is a new preference setting in the Window → Preferences → StreamBase Studio → Authoring → EventFlow Rendering panel, Use slanted arcs during arc routing and auto-layout.

When enabled (the default), arcs placed by the Layout Application (Ctrl+L) and Reroute Arcs (Ctrl+Alt+L) functions are shown with an angled slant between components. When disabled, arcs are only placed horizontally or vertically, with right angles for every direction change. This feature restores to release 7.1.7 and later the layout cosmetics of StreamBase releases 6.6 and earlier. In addition, an automatically laid out module is now slightly denser than in earlier 7.x releases.

This release adds the getParallelRoot() function.

In the Pattern operator, the Window Size field in the Pattern Settings tab now accepts a module parameter in the form ${ParamName}.

The FIX Schema Designer (FSD), added in release 7.1.3, now supports the FIX/FAST protocol. FAST stands for FIX Adapted for STreaming, and is a FIX variation used by some trading venues. To design a schema to communicate with such a venue, select FAST Data Dictionary File in the FSD's Select Data Dictionary dialog, then navigate to select the dictionary file provided by the venue. In all other ways, the FSD works the same as before.

The input adapters for IBM WebSphere MQ and Wall Street Systems were updated with two new properties: Include Depth Field and Syncpoint on Get. These properties are enabled by default for compatibility with previous releases of these adapters. Disabling both settings significantly improves performance of these adapters. See IBM WebSphere MQ Input Adapter and Wall Street Systems Input Adapter.

The Thomson Reuters Enterprise Platform for Real-Time (TREP-RT) Subscribing Input adapter (formerly known as the Thomson Reuters RMDS Subscribing Input adapter) now supports thin tuples for the MarketPrice message model. Previously, thin tuples were supported for the MarketFeed message model only, although the adapter incorrectly allowed thin tuples to be configured for other message models.

In addition, the adapter gained a new property, Include Subscribe Pass-Thru Field property on the Tuple Properties tab of its Properties view. When selected, this property requires a field named PassThru to be added to the schema of the DynamicSubscribe input port. There are no constraints on this field's data type. The adapter copies the value from this field to a corresponding field of each each market data tuple emitted as a result of the subscription.

The TIBCO Rendezvous Subscribing Input Adapter has a new property, Ignore Advisory Messages. When enabled, the adapter discards messages with subjects that begin with _RV.

The E-mail Sender Output Adapter has two new properties, Enable Event Port and Event on Send Success. When the first is enabled, the adapter gains an event output port that emits event tuples when errors occur sending e-mail. When the second property is enabled, the event port also emits a tuple when e-mail is successfully sent.

This release adds support for Vertica 5.0, both for JDBC access and for high-performance bulk loading with native connectivity, and drops support for Vertica 3.5.

The JAR files supporting the StreamBaseFIX FIX engine were updated to version 2.10.7. The JAR files supporting FIX/FAST were updated to version 2.11.8.

This release includes a new adapter for the Exegy Ticker Plant data feed. The adapter is described in Exegy Input Adapter in the Adapters Guide, and has a sample, described in Exegy Adapter Sample in the Samples Guide.

The three Thomson Reuters RMDS adapters were renamed to reflect the new name of the protocol formerly known as RMDS: Thomson Reuters Enterprise Platform for Real-Time, or TREP-RT. The adapters are otherwise unchanged. See:

The Results grid in the Thomson Reuters Schema Designer view now has an In Summary column, which for each FID row is either blank or contains Yes. Use this column to help select fields when generating a schema for a summary-only tuple. See Thomson Reuters Schema Designer View.

The StreamBase utilities jsbadmin, jsbc, sbbundle, and sbfeedsim were updated to accept the -J option anywhere on the command line instead of its former required first position. You can now specify -J options with or without a following space.

The expression language's eval() function gained an optional fourth parameter to specify the evaluation cache size. See eval().

The .NET Client Library was rewritten to improve the performance of creating tuples and accessing tuple field values, with initial tests showing a speedup of 10 to 40 times from the previous API. Most of the .NET API for building StreamBase clients is now a pure .NET implementation, although some classes (such as StreamBaseClient) remain based on the C++ API. (The .NET API for building StreamBase Server monitor applications is unchanged.)

Rewriting most of the API as pure .NET forced some changes in the interface, as described in Migrating .NET Clients in the API Guide. You may need to make source code changes for existing .NET client applications and recompile them in order to accommodate the new API.

The Query operator associated with a JDBC data construct has a new property, Timeout, on the Query Settings tab of the Properties view. Use this field to specify an integer time in milliseconds after which this particular query times out. You can still use the jdbc-query-timeout option in the <data-source> element of the server configuration file to specify a default timeout for all queries to that data source.

This release adds the Java system property streambase.jdbc.max-repeat-exceptions. The default value of 1 tells StreamBase Server that a single instance of a JDBC exception is regarded as an exception. Specify zero to mean that JDBC exceptions can be repeated without limit. Use an integer, n, greater than 1 to specify that JDBC exceptions might occur n times before succeeding.

The Timestamp class in the C++ Client Library now uses snap to end of month semantics for the setMonth() method. The following code fragment illustrates how this works:

Timestamp tm;
tm.setYear(2011);
tm.setMonth(10);
tm.setDayOfMonth(31);
// tm now represents October 31, 2011
tm.setMonth(2);
// tm now represents February 28, 2011

The sbd command has a new option, --override-version-check. By default, when you ask StreamBase Server to run a bundle file, it checks the StreamBase version that created the bundle and refuses to run a bundle not created with the same major.minor release number. You can use the new option to direct the server to override this check and try to run the bundle file anyway. Incompatibilities between the bundled application and the server may still prevent the bundle from running.

The --if-modified option of the sbargen command, when determining whether an application needs to be re-archived, now ignores changes in files whose names match the following default regular expression patterns:  .*\.log,  .*\.bak,  .*~, and  #.*#

You can customize the list of exclusion patterns with the new --exclude-pattern option, which can be specified multiple times.

The expression language gained the join() function, the opposite of split(). Use join() to return a string formed by concatenating the members of a list of any type, and interposing a specified character or string between each element.

The Excel External adapter was updated such that the buffer-size configuration parameter and TUPLENUM tag are now limited to values between 1 and 1000. Prior to this change, there was no limit on buffer-size, and TUPLENUM was limited to values between 1 and 999.

The embedded JMS Input and Output adapters were updated such that the following events are now sent to the Status output port:

In addition, both adapters have a new property Log Full Call Stacks. When selected, exception call stacks are shown independent of the adapter's Log Level setting.

The 29West LBM Subscribing and Publishing adapters were updated to support pre-defined messages. Enable support for this feature with the new Enable Pre-defined Messages property. The adapters have several other new properties that control how a publish and subscribe adapter pair agree on message definitions in cooperation with the StreamBase schema.

The StreamBase documentation for release 7.1.5 included the following changes independent of the above updates:

This release includes a preview of the background typechecking feature, which is expected to be added to a future release. To enable, use Window → Preferences, then open the StreamBase Studio → Typechecking panel and select the check box labeled Typecheck EventFlow Editors in background. This directs Studio to run typechecking operations as a background task, with details visible in the Progress view. In the default disabled state, Studio shows a modal dialog box during long typecheck operations.

This feature allows you to enable the Automatically typecheck components preference even when editing large modules with long typecheck requirements. If you encounter any issues using this feature, report them to StreamBase Technical Support.

As of this release, all Windows MSI installer files are digitally signed, including the installers for external adapters and Frameworks.

The field name qualifier input. is now valid in expressions in the Aggregate operator, and has the same meaning as the input1. qualifier.

Since release 7.0, StreamBase Server has been instrumented with a JMX-compliant Managed Bean that provides access to status information and provides control methods similar to the sbadmin command. As of this release, JMX support is extended to allow management of dynamic variable values, and to allow several profiler operations. See JMX Support.

This release of Studio provides better support for opening two or more EventFlow Editor sessions on the same EventFlow file. This feature is described on the EventFlow Editor Canvas topic of the StreamBase Studio Reference.

In the Definitions tab of the EventFlow Editor, the Delete key is no longer blocked if you selected multiple constants, schemas, and table schemas at the same time. This allows you to delete multiple related items in one pass.

As a convenience, the New menu in Studio now includes entries for Class and Interface, which lets you create new Java class or interface files without switching to the Java perspective. If you start this release with an existing Studio workspace from a previous release, you must run Window → Reset Perspective to make this feature visible.

Release 7.1.0 introduced the ability to drag an operator from the Palette view and insert it directly into an arc, with automatic reconnection of the arc to the operator's input and output ports. As of 7.1.4, you can now insert a global Java operator into an arc in the same ways. This feature does not work for the StreamBase Admin operator (which has only an input port by default), but works for the other four global Java operators and for any custom Java operators that have at least one input and one output port. The same feature works by selecting the arc of interest, then invoking the O V keyboard shortcut. This feature is described in Inserting a Component Into an Arc.

When exporting a Studio project to an archive file, Studio does not add the java-src folder to the archive if the folder is empty. In previous releases, when importing that archive file into Studio, the project would fail typechecking only because of the required but missing java-src folder. Starting with this release, when importing projects from an archive file, Studio automatically adds the java-src folder if not present in the archive.

The functions new_tuple_subset() and new_tuple_subset_loose() were added to the expression language.

To provide better alignment of the StreamBase .NET Client Library with the Java Client Library, the .NET API was updated to add new field creation methods to StreamBase.SB.Schema, and to deprecate older field creation methods.

In the com.streambase.sb.unittest package, in class SBServerManager, the startContainers() methods that accept an initial Set<String> argument were extended to accept null as an empty set. The result is to start all containers.

The Trading Technologies FIX adapter was updated to support through version 7.7.2 of the Trading Technologies data dictionary.

The Wombat MAMA Input adapter was updated to support version 5 of the MAMA API. To specify the use of MAMA version 5, in the adapter's Properties view, for the MAMA Version property, select 4.x and above, which is now the default setting.

The TBF Input adapter was updated to add new configuration options, QueueCapacity, RequestRetransmitOnHeartbeatTimeout, and to increase the default blocking capacity of the adapter.

JAR files provided by IBM that support WebSphere MQ are no longer shipped as part of the StreamBase kit. Documentation topics for the IBM WebSphere MQ Input and Output adapters and sample were updated to describe where to install the MQ JAR files you obtain from IBM.

JAR files provided by Deutsche Bank that support the AutobahnFX Trading System are no longer shipped as part of the StreamBase kit. Documentation topics for the AutobahnFX Trading System adapter and its sample were updated to describe where to install the Autobahn FX JAR files you obtain from Deutsche Bank.

The data dictionary for the UBS FIX adapter was updated to the latest version.

The E-mail Sender Output adapter was updated to send its e-mail messages in a separate, background thread and to add the new Outgoing Message Queue Capacity property. Set this to a value large enough to accommodate the maximum expected e-mail message burst.

The Log Output Adapter sample was revised to show three examples of formatting that the adapter can apply to log messages. The Log Output adapter topic in the Adapters Guide was revised, corrected, and expanded, and now describes the Log Asynchronously option. The sample's topic in the Samples Guide was revised and expanded.

The Binary File Reader adapter now emits a close event tuple when it finishes reading a file.

The StreamBase documentation for release 7.1.4 included the following changes independent of the above updates:

This release introduces the FIX Schema Designer, which provides a way to generate named schemas for a set of FIX message types for use with the FIX adapter or any StreamBase adapter that uses the FIX protocol. See FIX Schema Designer View for details.

If you use an existing Studio workspace after installing this release, the FIX Schema Designer view may not appear by default. In this case, either run Window → Reset Perspective for the SB Authoring perspective, or directly open the new view with Window → Show View → Other → StreamBase FIX → FIX Schema Designer.

In the Module Search Path panel of the Project Properties dialog, you can now designate folders as private. Modules and interfaces in private folders remain in the module search path for the containing project, but are removed from the module search for any referencing projects. See Private Module Folders on the Module Search Path page.

Release 7.1.0 introduced the ability to drag an operator from the Palette view and insert it directly into an arc, with automatic reconnection of the arc to the operator's input and output ports. As of 7.1.3, you can now insert an input or output adapter into an arc in the same ways. This feature only works for adapters whose default configuration has at least one input port and at least one output port. If the adapter has more than one input or output port by default, the arc is connected to the first port on that side. Adapters that do not meet this criterion are dropped onto the canvas as before at the arc's location. This feature is especially useful for inserting a Log Output adapter into an arc by dragging the Output Adapter icon from the Palette view to the arc. This feature is described in Inserting a Component Into an Arc.

StreamBase Server authentication against LDAP servers that formerly required using the StreamBase Proxy Server was moved to StreamBase Server itself, and was updated to authenticate and authorize users against multiple LDAP domains. These features are enabled by means of the following new or updated child elements of the security element of the server configuration file:

Initial documentation for these features is in comments in the skeleton configuration file generated with sbd -s.

You can now copy schemas from streams and components in interface files as well as from EventFlow and StreamSQL modules, when using the Copy Schema From dialog. See Copying Schemas in the Authoring Guide.

For each application or module run in StreamBase Studio, Studio now stores the output streams you select for viewing in the Application Output view, and restores the same stream selection the next time you run the same application. The saved stream selections persist even if Studio is closed and reopened. When you launch another application for the first time, the stream selection in the Application Output view is reset to All Streams.

Entries in the Module Call Hierarchy View now show the name of an Extension Point first, followed by the StreamBase interface file implemented by that extension point. This more accurately reflects the action to expect from double-clicking an extension point name, which is to select and highlight that extension point in the EventFlow Editor for the containing module. To open the interface file itself, right-click and select Open Module File from the context menu, as before.

The Trace Debugger view now has a link that pops up a reminder of the color legend for the debugger.

In the .NET Client Library, the StreamBase::SB::Timestamp class was made serializable.

The BM&FBovespa UMDF adapter allows a StreamBase application to connect to BM&FBovespa's Unified Market Data Feed to receive market data in the form of FIX/FAST messages. The adapter uses the high-speed, low-latency StreamBaseFIX engine to decode the incoming FAST messages. The adapter is described in BM&FBovespa UMDF Input Adapter and has a sample, described in BM&FBOVESPA UMDF Input Adapter Sample.

The Microsoft Excel External adapter was updated to optionally prompt for a password, which it automatically enciphers and passes to StreamBase Server for authentication. Enable this feature by setting the prompt-for-password element's value to true in the adapter's configuration file. This feature is described in the Configuration File section of the Excel adapter documentation.

The sample for the Thomson Reuters RMDS Subscribing Input adapter was updated to add useMarketfeedUpdateType=true to its default configuration file. For SSL connections when using the Market Feed message model only, this directs the adapter to emit Market Feed corrections as CORRECTION messages.

The Lime Citrius Quote adapter was updated to use version 2.0.6 of the Lime Citrius API.

The TBF Input adapter was updated to add a STAMP configuration parameter, RetranRetryWaitTime.

The output adapter in the FXall Relationship Trading Provider adapter set was updated to add the Log XML Messages and INFO Level property. Previously, only the input adapter of this adapter set supported this option.

The Trading Technologies FIX adapter was updated to support version 7.6.5.29 of the Trading Technologies data dictionary.

The StreamBase documentation for release 7.1.3 included the following changes independent of the above updates:

The Velocity Analytics tick-store database from Thomson Reuters is now supported for standard JDBC access.

In a project refresh, Studio now runs typechecking only for modules that are currently visible in the foreground, and defers typechecking for modules whose tab is in the background. Project refresh occurs when you run StreamBase → Refresh Project Typecheck Environment (Ctrl+F5) or when you save a module or interface used by other modules. Any deferred typechecking runs when you bring a background module to the foreground, including when prompted to save the module on Studio shutdown.

An SLF4J Logger named EventFlowEditorTypecheck now reports whenever an Editor session typechecks. You can see these logs in the Studio Support Console with StreamBase Logging Level set to DEBUG or higher, or you can specify custom logging for this Logger in your logging configuration file. See Using StreamBase Logging.

Typecheck warnings, introduced in release 7.1.0, are now shown at the top of the Properties view for a component with a warning condition. See Typecheck Warnings.

To provide better compatibility with version control systems, in cases where only layout changes have occurred, Studio now saves only the module's .sblayout file. In previous releases, Studio would save both .sbapp and .sblayout files for any change.

Basic StreamBase authentication now supports connecting to StreamBase Server with URLs that include an enciphered password, as described in Enciphering Passwords. This affects all client access to the server, including StreamBase-provided clients such as sbc and sbadmin, and affects access from most adapters.

The performance of the EventFlow Debugger was dramatically improved for applications that carry very large schemas with a large number of fields.

The New Adapter Wizard now automatically refreshes the current project's typecheck environment on completion of the wizard, so that the newly created adapter's icon automatically appears in the Project Adapters folder of the Insert Input Adapter or Insert Output Adapter dialog, as appropriate. (The New Operator Wizard gained this functionality in release 7.1.0.) Documentation for both wizards was updated and clarified. See Using the StreamBase Embedded Adapter Wizard and Using the Java Operator Wizard.

In StreamBase Server configuration files, the param child element of the data-source element accepts a new value, jdbc-query-timeout. This parameter specifies an integer number of milliseconds that StreamBase waits for each JDBC query operation to execute. The default is 0, which means wait forever for each query to return; this default matches the behavior of StreamBase before this parameter was added. Specify a value such as 15000 (15 seconds) to prevent StreamBase Server from hanging in rare cases where the JDBC server never responds to a query. See StreamBase Server Configuration File XML Reference.

The postShutdown() method of the Operator class was updated to more strictly wait for an operator or adapter's run threads to exit (or time out) before running. This strict behavior of postShutdown() is the default behavior as of this release, and improves the shutdown behavior of all operators and adapters, whether provided by StreamBase or custom. You can restore the postShutdown() method's non-strict behavior by setting the streambase.java-operator.unsynchronized-shutdown system property to true.

Custom operators and adapters can now register independent threads that are not derived from the Operator class for purposes of thread CPU tracking in StreamBase profiling tools. In the Javadoc for the StreamBase Client Library, see registerUnmanagedThread() and unregisterUnmanagedThread() in Operator.RuntimeEnvironment.

The Drools operator was updated to add an optional status port specified with the new Enable status port property. This port conveys the status of rules entered at runtime on the dynamic rule port. The documentation page for the operator was updated to clarify the format of rules entered on this port.

The Thomson Reuters RMDS Subscribing Input adapter was updated to better distinguish quotes from trades. The market data output port now contains an optional ResponseType field, which supersedes the UnsolicitedRefresh field. The field is enabled by selecting the Include OMM Response Type Field property in the Tuple Properties tab in the adapter's Properties view. The field contains SOLICITED or UNSOLICITED for refresh messages, or contains QUOTE, TRADE, CORRECTION, and so on, for update messages.

The JMS embedded adapters were updated to support connections to OpenMQ without JNDI.

The Deutsche Bank AutobahnFX Trading System adapter was updated to support ladder rungs for swaps and to provide performance enhancements.

The CitiFX FIX adapter was updated to support the Executable Streaming Prices for Forwards product as well as ESP for Spot. Continue to select the Spot option in the adapter's Properties view for either ESP product.

The TBF Input adapter was updated to support the new MaxQueueLength and RetransRetryCount properties in the STAMP session configuration file. See TBF Input Adapter for details.

The StreamBase documentation for release 7.1.2 included the following changes independent of the above updates:

Starting with this release, the FIX adapter can be configured to take advantage of a new FIX engine, StreamBaseFIX, in addition to the QuickFIX/J, CameronFIX, and Appia FIX engines already supported. StreamBaseFIX is derived from the B2Bits Antenna FIX engine from EPAM Systems, and allows high-speed, low-latency communication using the FIX protocol.

StreamBaseFIX can be used with the FIX adapter and with all StreamBase adapters that use the FIX protocol, including the Bolsa Commercio Santiago FIX, Bovespa, CitiFX FIX, Currenex, EBS, FXall FIX, Goldman Sachs Electronic Trading FX, Integral FX Inside FIX, LavaFX, Lime FIX, Nomura FX FIX, Raptor, Trading Technologies, and UBS FIX adapters.

The StreamBaseFIX engine is included with the base StreamBase kit, but its use is separately licensed. Contact StreamBase Systems Technical Support or your StreamBase Sales Engineer for further details.

In previous releases, container connections were restricted to streams exiting one container and entering a stream in a separate container. As of this release, that restriction is relaxed, and you can configure stream to stream connections within the same container, where the destination and source container names are the same. Intra-container connections must be Asynchronous, and the same access restrictions apply: that is, streams you wish to connect to or from in sub-modules must be marked as Always exposed in EventFlow modules, or public in StreamSQL modules.

The Module Explorer view shows all StreamBase module files and folders containing such files in the module search path of the currently open EventFlow or StreamSQL module. The default display order is to list files and folders in alphabetical order. Starting with this release, there is a Search Path Order button in the view's toolbar. Click this button to show the view in module search path order. The button's selected state persists between Studio sessions.

The Module Call Hierarchy view now has a Filter field that lets you show only modules and interfaces whose names match a pattern you specify.

In the Data File Options dialog invoked from the Feed Simulation Editor, the column headings of the File preview grid are now numbered instead of blank when the First row as header option is in its default disabled state. This helps you line up data file columns to field names when using the Map to file control of the same dialog.

In addition, the First row as header option is now automatically dimmed and unavailable if the stream for which you are building a data file specifies an empty schema. Why use a data file as input to a stream with no fields? It is possible to use the Timestamp from column feature even with an empty schema stream, as described in Using Timestamp from Column with Empty Schemas.

The new nullif() function evaluates two arguments. If the arguments are equal, the function returns null; otherwise, the first argument is returned. This function can be used to evaluate fields before and after an event, and to send a field downstream only if it has changed, otherwise null.

The new eval() function takes either two or three arguments. With two arguments, the function evaluates a simple expression entered as a string and returns the result using the data type of the second argument. With three arguments, the second field contains a tuple, and the expression in the first field can be evaluated against any fields in that tuple. The third argument specifies the return data type. Because of environment limitations, the eval() function does not run successfully at the command prompt with sbd --eval, but runs as expected in EventFlow and StreamSQL expressions.

The six StreamBase adapters that connect StreamBase applications to the Reuters infrastructure were rebranded as Thomson Reuters adapters. Functionality for all Thomson Reuters adapters remains the same as before.

The FIX adapter, and all StreamBase adapters that use the QuickFIX/J FIX engine, were updated to take advantage of the version of the LogBack logging libraries included with the StreamBase base kit. This allows you to configure adapter-specific entries in your logback.xml file that specify file rolling for log files that capture QuickFIX/J messages. Contact StreamBase Technical Support if you need help configuring this option.

The ActivFeed Input adapter was updated to support Activ's Service.WorkstationService address to support multiple connections with shared user credentials. See ActivFeed Input Adapter in the Adapters Guide.

The three Thomson Reuters RMDS adapters were renamed to reflect the new name of the protocol formerly known as RMDS: Thomson Reuters Enterprise Platform for Real-Time, or TREP-RT. The adapters are otherwise unchanged. See:

The input adapters for IBM WebSphere MQ and Wall Street Systems were updated with two new properties: Include Depth Field and Syncpoint on Get. These properties are enabled by default for compatibility with previous releases of these adapters. Disabling both settings significantly improves performance of these adapters. See IBM WebSphere MQ Input Adapter and Wall Street Systems Input Adapter.

Starting with this release, the Connect on adapter init property of the StreamBase to StreamBase input and output adapters no longer has any effect. Both adapters now behave as though the property is disabled (meaning they do not connect on startup), which conforms to StreamBase best practices. This change applies only to the 7.0.x release series.

The FIX Schema Designer (FSD), added in release 7.0.8, now supports the FIX/FAST protocol. FAST stands for FIX Adapted for STreaming, and is a FIX variation used by some trading venues. To design a schema to communicate with such a venue, select FAST Data Dictionary File in the FSD's Select Data Dictionary dialog, then navigate to select the dictionary file provided by the venue. In all other ways, the FSD works the same as before.

The StreamBase utilities jsbadmin, jsbc, sbbundle, and sbfeedsim were updated to accept the -J option anywhere on the command line instead of its former required first position. You can now specify -J options with or without a following space.

The .NET Client Library was rewritten to improve the performance of creating tuples and accessing tuple field values, with initial tests showing a speedup of 10 to 40 times from the previous API. Most of the .NET API for building StreamBase clients is now a pure .NET implementation, although some classes (such as StreamBaseClient) remain based on the C++ API. (The .NET API for building StreamBase Server monitor applications is unchanged.)

Rewriting most of the API as pure .NET forced some changes in the interface, as described in Migrating .NET Clients in the API Guide. You may need to make source code changes for existing .NET client applications and recompile them in order to accommodate the new API.

The Timestamp class in the C++ Client Library now uses snap to end of month semantics for the setMonth() method. The following code fragment illustrates how this works:

Timestamp tm;
tm.setYear(2011);
tm.setMonth(10);
tm.setDayOfMonth(31);
// tm now represents October 31, 2011
tm.setMonth(2);
// tm now represents February 28, 2011

The expression language gained a join() function, the opposite of split(). Use join() to return a string formed by concatenating the members of a list of any type, and interposing a specified character or string between each element.

The Excel External adapter was updated such that the buffer-size configuration parameter and TUPLENUM tag are now limited to values between 1 and 1000. Prior to this change, there was no limit on buffer-size, and TUPLENUM was limited to values between 1 and 999.

The 29West LBM Subscribing and Publishing adapters were updated to support pre-defined messages. Enable support for this feature with the new Enable Pre-defined Messages property. The adapters have several other new properties that control how a publish and subscribe adapter pair agree on message definitions in cooperation with the StreamBase schema.

The StreamBase documentation for release 7.0.11 included the following changes independent of the above updates:

To provide better alignment of the StreamBase .NET Client Library with the Java Client Library, the .NET API was updated to add new field creation methods to StreamBase.SB.Schema, and to deprecate older field creation methods.

The Trading Technologies FIX adapter was updated to support through version 7.7.2 of the Trading Technologies data dictionary.

The Wombat MAMA Input adapter was updated to support version 5 of the MAMA API. To specify the use of MAMA version 5, in the adapter's Properties view, for the MAMA Version property, select 4.x and above, which is now the default setting.

The TBF Input adapter was updated to add a new configuration option, RequestRetransmitOnHeartbeatTimeout.

JAR files provided by IBM that support WebSphere MQ are no longer shipped as part of the StreamBase kit. Documentation topics for the IBM WebSphere MQ Input and Output adapters and sample were updated to describe where to install the MQ JAR files you obtain from IBM.

JAR files provided by Deutsche Bank that support the AutobahnFX Trading System are no longer shipped as part of the StreamBase kit. Documentation topics for the AutobahnFX Trading System adapter and its sample were updated to describe where to install the Autobahn FX JAR files you obtain from Deutsche Bank.

The data dictionary for the UBS FIX adapter was updated to the latest version.

The E-mail Sender Output adapter was updated to send its e-mail messages in a separate, background thread and to add the new Outgoing Message Queue Capacity property. Set this to a value large enough to accommodate the maximum expected e-mail message burst.

The Log Output Adapter sample was revised to show three examples of formatting that the adapter can apply to log messages. The Log Output adapter topic in the Adapters Guide was revised, corrected, and expanded. The sample's topic in the Samples Guide was revised and expanded.

The Binary File Reader adapter now emits a close event tuple when it finishes reading a file.

The StreamBase documentation for release 7.0.10 included the following changes independent of the above updates:

The field name qualifier input. is now valid in expressions in the Aggregate operator, and has the same meaning as the input1. qualifier.

The TBF Input adapter was updated to add a configuration option, QueueCapacity, and to increase the default blocking capacity of the adapter.

As of this release, all Windows MSI installer files are digitally signed, including the installers for external adapters and Frameworks.

The StreamBase documentation for release 7.0.9 included the following changes independent of the above updates:

This release introduces the FIX Schema Designer, which provides a way to generate named schemas for FIX message types for use with the FIX adapter or any StreamBase adapter that uses the FIX protocol. See FIX Schema Designer View for details.

If you use an existing Studio workspace after installing this release, the FIX Schema Designer view may not appear by default. In this case, either run Window → Reset Perspective for the SB Authoring perspective, or directly open the new view with Window → Show View → Other → StreamBase FIX → FIX Schema Designer.

You can now copy schemas from streams and components in interface files as well as from EventFlow and StreamSQL modules, when using the Copy Schema From dialog. See Copying Schemas in the Authoring Guide.

Entries in the Module Call Hierarchy View now show the name of an Extension Point first, followed by the StreamBase interface file implemented by that Extension Point. This more accurately reflects the action to expect from double-clicking an Extension Point name, which is to select and highlight that Extension Point in the EventFlow Editor for the containing module. To open the interface file instead, right-click and select Open Module File from the context menu, as before.

The Trace Debugger view now has a link that pops up a reminder of the color legend for the debugger.

The postShutdown() method of the Operator class was updated to more strictly wait for an operator or adapter's run threads to exit (or time out) before running. This strict behavior of postShutdown() is the default behavior as of this release, and improves the shutdown behavior of all operators and adapters, whether provided by StreamBase or custom. You can restore the postShutdown() method's non-strict behavior by setting the streambase.java-operator.unsynchronized-shutdown system property to true.

Basic StreamBase authentication now supports connecting to StreamBase Server with URLs that include an enciphered password, as described in Enciphering Passwords. This affects all client access to the server, including StreamBase-provided clients such as sbc and sbadmin, and affects access from most adapters.

Custom operators and adapters can now register independent threads that are not derived from the Operator class for purposes of thread CPU tracking in StreamBase profiling tools. In the Javadoc for the StreamBase Client Library, see registerUnmanagedThread() and unregisterUnmanagedThread() in Operator.RuntimeEnvironment.

In the .NET Client Library, the StreamBase::SB::Timestamp class was made serializable.

The BM&FBovespa UMDF adapter allows a StreamBase application to connect to BM&FBovespa's Unified Market Data Feed to receive market data in the form of FIX/FAST messages. The adapter uses the high-speed, low-latency StreamBaseFIX engine to decode the incoming FAST messages. The adapter is described in BM&FBovespa UMDF Input Adapter and has a sample, described in BM&FBOVESPA UMDF Input Adapter Sample.

The Thomson Reuters RMDS Subscribing Input adapter was updated to add useMarketfeedUpdateType=true to its default configuration file. For SSL connections when using the Market Feed message model only, this directs the adapter to emit Market Feed corrections as CORRECTION messages.

The Deutsche Bank AutobahnFX Trading System adapter was updated to support ladder rungs for swaps and to provide performance enhancements.

The CitiFX FIX adapter was updated to support the Executable Streaming Prices for Forwards product as well as ESP for Spot. Continue to select the Spot option in the adapter's Properties view for either ESP product.

The TBF Input adapter was updated to support the new MaxQueueLength, RetransRetryCount, and RetranRetryWaitTime properties in the STAMP session configuration file. See TBF Input Adapter for details.

The Lime Citrius Quote adapter was updated to use version 2.0.6 of the Lime Citrius API.

The output adapter in the FXall Relationship Trading Provider Adapter set was updated to add the Log XML Messages and INFO Level property. Previously, only the input adapter of this adapter set supported this option.

The Trading Technologies FIX adapter was updated to support version 7.6.5.29 of the Trading Technologies data dictionary.

The StreamBase documentation for release 7.0.8 included the following changes independent of the above updates:

The Velocity Analytics tick-store database from Thomson Reuters is now supported for standard JDBC access.

In previous releases, container connections were restricted to streams exiting one container and entering a stream in a separate container. As of this release, that restriction is relaxed, and you can configure stream to stream connections within the same container, where the destination and source container names are the same. Intra-container connections must be Asynchronous, and the same access restrictions apply: that is, streams you wish to connect to or from in sub-modules must be marked as Always exposed in EventFlow modules, or public in StreamSQL modules.

To provide better compatibility with version control systems, in cases where only layout changes have occurred, Studio now saves only the module's .sblayout file. In previous releases, Studio would save both .sbapp and .sblayout files for any change.

The Module Explorer view shows all StreamBase module files and folders containing such files in the module search path of the currently open EventFlow or StreamSQL module. The default display order is to list files and folders in alphabetical order. Starting with this release, there is a Search Path Order button in the view's toolbar. Click this button to show the view in module search path order. The button's selected state persists between Studio sessions.

In StreamBase Server configuration files, the param child element of the data-source element accepts a new value, jdbc-query-timeout. This parameter specifies an integer number of milliseconds that StreamBase waits for each JDBC query operation to execute. The default is 0, which means wait forever for each query to return; this default matches the behavior of StreamBase before this parameter was added. Specify a value such as 15000 (15 seconds) to prevent StreamBase Server from hanging in rare cases where the JDBC server never responds to a query. See StreamBase Server Configuration File XML Reference.

The Drools operator was updated to add an optional status port specified with the new Enable status port property. This port conveys the status of rules entered at runtime on the dynamic rule port. The documentation page for the operator was updated to clarify the format of rules entered on this port.

The new nullif() function evaluates two arguments. If the arguments are equal, the function returns null; otherwise, the first argument is returned. This function can be used to evaluate fields before and after an event, and to send a field downstream only if it has changed, otherwise null.

The new eval() function takes either two or three arguments. With two arguments, the function evaluates a simple expression entered as a string and returns the result using the data type of the second argument. With three arguments, the second field contains a tuple, and the expression in the first field can be evaluated against any fields in that tuple. The third argument specifies the return data type. Because of environment limitations, the eval() function does not run successfully at the command prompt with sbd --eval, but runs as expected in EventFlow and StreamSQL expressions.

The Thomson Reuters RMDS Subscribing Input adapter was updated to better distinguish quotes from trades. The market data output port now contains an optional ResponseType field, which supersedes the UnsolicitedRefresh field. The field is enabled by selecting the Include OMM Response Type Field property in the Tuple Properties tab in the adapter's Properties view. The field contains SOLICITED or UNSOLICITED for refresh messages, or contains QUOTE, TRADE, CORRECTION, and so on, for update messages.

The FIX adapter, and all StreamBase adapters that use the QuickFIX/J FIX engine, were updated to take advantage of the version of the LogBack logging libraries included with the StreamBase base kit. This allows you to configure adapter-specific entries in your logback.xml file that specify file rolling for log files that capture QuickFIX/J messages. Contact StreamBase Technical Support if you need help configuring this option.

The ActivFeed Input adapter was updated to support Activ's Service.WorkstationService address to support multiple connections with shared user credentials. See ActivFeed Input Adapter in the Adapters Guide.

The JMS embedded adapters were updated to support connections to OpenMQ without JNDI.

The StreamBase documentation for release 7.0.7 included the following changes independent of the above updates:

Starting with this release, the FIX adapter can be configured to take advantage of a new FIX engine, StreamBaseFIX, in addition to the QuickFIX/J, CameronFIX, and Appia FIX engines already supported. StreamBaseFIX is derived from the B2Bits Antenna FIX engine from EPAM Systems, and allows high-speed, low-latency communication using the FIX protocol.

StreamBaseFIX can be used with the FIX adapter and with all StreamBase adapters that use the FIX protocol, including the Bolsa Commercio Santiago FIX, Bovespa, CitiFX FIX, Currenex, EBS, FXall FIX, Goldman Sachs Electronic Trading FX, Integral FX Inside FIX, LavaFX, Lime FIX, Nomura FX FIX, Raptor, Trading Technologies, and UBS FIX adapters.

The StreamBaseFIX engine is included with the base StreamBase kit, but its use is separately licensed. Contact StreamBase Systems Technical Support or your StreamBase Sales Engineer for further details.

The six StreamBase adapters that connect StreamBase applications to the Reuters infrastructure were rebranded as Thomson Reuters adapters. Functionality for all Thomson Reuters adapters remains the same as before.

In previous releases, the Extract as Module command (in the context menu of the EventFlow canvas) was extracting all parameters and their settings from the parent module to the new child module. The command was updated such that it now extracts only parameters actually used by the components selected for extraction. Parameters with default values in the parent module are copied with the same values to the child module. Parameter settings in the child module are updated to link to the parent module's parameter values, in the form ParamName = ${ParamValue}.

This release adds Studio highlight and location support in text searches for StreamBase file types in the Studio workspace initiated by the Eclipse Search → File dialog. After a search, in the Search view, use the up and down arrow buttons (or the Ctrl+. shortcut) to select each found location in sequence. Starting with this release, selecting a found location in the Search view opens the editor for the StreamBase file in which the search phrase was found, and highlights the containing line. For EventFlow files, the component that contains the search phrase is selected and centered on the canvas. This feature is described in a new Authoring Guide page, Text Search in Studio.

When using sbprofile to generate a profiling output file, you can now append a --roll-size or --roll-time option to automatically roll over the output file when it reaches a specified size or when a certain time has elapsed. See sbprofile for syntax details.

The External Process and StreamBase Admin operators both gained a new property, Number of async worker threads. For the StreamBase Admin operator, this property is on the Operator Properties tab; for the External Process operator, the property is on the Advanced tab and is only active when the Run this command asynchronously check box is selected. The default value of 1 means that the operator's commands are performed serially, and this default behavior is new for both operators. Positive values specify a limit on the number of threads to spawn to perform the operator's requested operations. Negative or 0 means the operator spawns an unlimited number of threads (which is the default behavior in previous releases).

The E-mail Sender Output adapter now has a new X-Headers tab in its Properties view, which allows you to specify multiple X-Header lines to be included in the emitted e-mail. See E-mail Sender Output Adapter in the Adapters Guide.

The StreamBase documentation for release 7.0.6 included the following updates independent of the changes described above:

The version of Eclipse that serves as a foundation for StreamBase Studio was updated to Eclipse 3.6.2, which retains backward compatibility for Eclipse 3.5 plug-ins. If you add third-party Eclipse plug-ins to Studio, make sure they are compatible with Eclipse 3.5 or 3.6.

The Oracle JDK installed for private use by StreamBase was updated to release 1.6.0_24. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

The expression language gained the new getServerURI() function that returns the StreamBase URI of the currently running server in the form sb://localhost:10000. The function reports the URI from the server's point of view, and thus always returns localhost as the host name. Use this function to obtain the port number plus any appended authentication parameters from a running server.

In previous releases, StreamBase samples and documentation recommended using systemproperty("streambase.uri") to retrieve this information. As of this release, the HA samples and documentation now show the use of getServerURI() instead.

Sites that run multiple instances of StreamBase Server in the same JVM need a way to distinguish the port number from the URI of separate server instances, which is not possible with a JVM-wide property. StreamBase Server continues to provide the streambase.uri system property in the 6.6.x and 7.0.x release series, but the property will be deprecated in a future release. StreamBase Systems recommends migrating your code to use the new getServerURI() function to prepare for the deprecation of the streambase.uri property.

The expression language was enhanced with a new function, isinterval(), that returns true if its timestamp argument is an interval timestamp.

Under some circumstances, StreamBase Server can emit warning messages at startup that indicate an environment variable has changed since the application was compiled. In most cases, these warnings have no consequences and can be ignored. However, when the server is loading a bundle file that includes a precompiled archive file, an environment variable warning message has the unintended side effect that the server ignores the bundled archive file and recompiles the application from the bundled source files. The bundled application does run normally, but for very large applications, at the cost of the recompilation time. To avoid recompiling a bundled archive file, you can now set the following system property:

streambase.check-app-environment-variables-changed=false

In Studio, the StreamBase panel of the Properties dialog for EventFlow and StreamSQL files now shows statistics about the selected file after it has been compiled by StreamBase Server at least once. Statistics are shown for the selected module and all submodules it references. See Application Statistics on the new StreamBase File Properties page.

The -w or --working-directory options for the sbd command were added in release 7.0.3. As of release 7.0.5, these options change earlier in the sbd startup sequence to the specified working directory path. This change means that every file the server needs to reference, including files specified on the sbd command line, must be specified relative to the working directory, or must be absolute paths.

For example, in 7.0.3 and 7.0.4, sbd -w subdir myApp.sbbundle required that myApp.sbbundle exist in the directory from which you entered the sbd command. Starting with this release, myApp.sbbundle must exist in subdir.

The sbargen command has a new option, --if-modified. When used, it directs sbargen to check the target .sbar file's dependencies, and only rebuild the target if it is older than its dependencies.

The SBServerManager.loadApp() method in the com.streambase.sb.unittest package now loads precompiled archive files (.sbar files) as well as EventFlow and StreamSQL files. As before, specified files are located on the module search path.

The FXall Relationship Trading Provider Input adapter was updated with the following enhancements: See FXall Relationship Trading Provider Adapter for details.

The Deutsche Bank AutobahnFX Trading System adapter was updated to support a new Include Latency Data property in the adapter's Properties view. When selected, this property adds two latency measurement fields to the Quotes output tuple expressed in nanoseconds. The QuoteArrivalTime field records the time between delivering a quote to the adapter and the time that quote arrives in the containing adapter. The QuoteHandoffTime field records the time a Quotes tuple spends enqueued after the adapter has called sendOutputAsync().

The 29West LBM adapter was updated such that all instances of the adapter now share a context if they specify the same LBM configuration file and section.

The Hotspot FX Control adapter (part of the Hotspot TXTrading System adapter suite) now supports two new actions: connect and disconnect. See Hotspot FX Trading System Adapter.

In processing update messages, the Reuters RMDS Subscribing input adapter now uses cached item state to populate metadata fields for OMM message models, as it has been doing for the non-OMM MarketFeed model.

The StreamBase documentation for release 7.0.5 included the following updates independent of the changes described above:

This release includes several related features that improve the ability to run bundled StreamBase applications:

The new sbd switch --use-custom-logging has the same effect as setting the STREAMBASE_USE_CUSTOM_LOGGING environment variable, as described in Using StreamBase Logging. The advantage of the new switch is that it can be used when sbd is configured to run as a Windows service, so that an alternate logging system can be specified without needing to set a global environment variable.

The expression language was enhanced with the replace() function for strings. The new function operates much like the Java String.replace() function.

Zero copy Tuple setter methods were added to the Java API. See the Javadoc for Tuple.getAllocatedTuple() and the comments added for Tuple.getTuple() and Tuple.setTuple().

The JMS Reader and JMS Writer embedded adapters were updated to support creating JMS endpoints dynamically, if the target JMS server supports this feature. See Dynamic Endpoints on the JMS Input and Output Adapters page for details.

As of release 7.0.4, the Vhayu Subscription and Vhayu Query adapters were removed from the StreamBase base kit. Vhayu Technologies was acquired by Thomson Reuters in August, 2009, and Vhayu's proprietary subscribe and publish API was replaced with the standard Reuters RMDS protocol. Thus, to subscribe to or publish to a Vhayu Velocity or Reuters Tick Capture Engine tick-store database, you can now use the Reuters RMDS Subscribing Input and Publishing Output adapters.

The StreamBase documentation for release 7.0.4 included the following updates independent of the changes described above:

The sbd command now recognizes the -w or --working-directory option that takes an absolute or relative path as an argument. If used, the sbd startup code changes to the specified directory before starting the Server. See the sbd reference page for further details.

Events sent by the container subsystem of the system container's control stream were changed to report STARTING, STOPPING, and STOPPED events for containers in addition to the existing START event. Connections to the system.control stream can now be synchronous, but only when used with caution. See Using Control Stream Features for the details of these changes and a discussion of the caution. That page also adds documentation for the existing heartbeat subsystem of the control stream.

When using the FIX Adapter with the Appia FIX engine, time-based FIX fields (UTCTimestamp, LocalMarketTime, and so on) are mapped to StreamBase field types differently than for other supported FIX engines. For details, see Field Type Mapping on the FIX Adapter documentation page.

Adapters can set a log level independent of the logging for the server that hosts the containing application, as described in Separate Adapter Log Levels on the Using StreamBase Logging page. The independent Log Level adapter property was added to the following adapters as of release 7.0.3: RSS Reader, TIBCO Embedded Input and Output, Vertica Load, XML File Writer, and XML Over HTTP adapters.

The StreamBase documentation for release 7.0.3 includes the following updates independent of the above updates:

The Reroute Arcs function ( button or Ctrl+Alt+L) returns to Studio as of release 7.0.2, and the automatic arc layout feature of releases 7.0.0 and 7.0.1 is now disabled. As in the 6.6 release series, the Reroute Arcs function routes arcs around components, using curves and bends in the arcs as needed. With no arcs selected, this function acts on all arcs on the current canvas; with one or more arcs selected, it acts only on the selected arcs. Use this function when you are satisfied with the component layout of the current canvas, but want to add curved arcs.

The Rearrange components and arcs function ( button or Ctrl+L) now runs the Reroute Arcs function automatically. In 6.6.x, these were independent controls that required running each in sequence. These functions are discussed in Component and Arc Layout Controls on the EventFlow Editor Canvas page.

The context menu in the Servers view of StreamBase Manager has a new option, Connect Automatically. This option connects to the selected server URI and stores persistent connection information; statistics from that server begin to display when the connection is made. If the connected server goes down and restarts, StreamBase Manager automatically reconnects and continues monitoring. If you exit and restart StreamBase Manager later, you only need to select the server's entry in the Servers View to reestablish the connection. See StreamBase Manager.

The Oracle JDK installed for private use by StreamBase was updated to release 1.6.0_23. As before, you can override this installed default to use a different supported JDK as described in Using an External JDK. The supported JDK versions are listed in Supported Configurations.

The names of the .bin files that contain both RPM and archive installation options for Linux and Solaris were extended to include a build number as well as architecture and platform tags. This helps you distinguish similar installation files when installing an upgrade on several platforms. See Installing StreamBase on Linux and Installing StreamBase on Solaris.

The installers now check the current platform and architecture, and issue a warning if you attempt run a non-matching installer version. Finally, the unpack option for the archive installer on Linux was improved, as described in Installing StreamBase on Linux.

StreamBase bundle files contain a generated bundle-specific server configuration file, as described on Application Bundling. For this reason, starting with this release, an error message results if you use sbd -f sbd.sbconf with a bundle file argument.

Adapters can set a log level independent of the logging for the server that hosts the containing application, as described in Separate Adapter Log Levels on the Using StreamBase Logging page. The independent Log Level adapter property was added to the following adapters as of release 7.0.2: Lime Citrius, Regular Expressions Reader, Regular Expressions Socket Reader, Sybase RAP4, Reuters RMDS Publishing, Reuters RMDS Subscribing, and the StreamBase to StreamBase input and output adapters.

The StreamBase documentation for release 7.0.2 included the following updates independent of the above updates:
