TIBCO Streaming Model Management Server (MMS) is a feature of the TIBCO StreamBase Platform, bringing optimal management and deployment of models and decision tables to AI-powered analytic applications running in Streaming Clusters.

This feature is available as a separate download and add-on installation.

The epadmin display statistics command has a new parameter --format <format type>. If this parameter is not present or is present with format type tabulartext, then the command outputs statistics reports in human-readable text form. If the format type is resultset and the global parameter --delimiter is present, then the command outputs statistics reports in encoded result set form, using the specified delimiter.

On Windows, the TIBCO Streaming installation places all Start Menu items under TIBCO Streaming 11.2. All item names include the release version, so that searching the Start Menu will find them more easily in side-by-side install situations.

Previously, the Union and Split operators had a 'magic port' at the bottom to quickly add another port (Input Port for Union and Output Port for Split) at the end. Now, an additional magic port has been introduced at the top of these operators to add a port at the beginning as well.

TIBCO Streaming now requires Java 22 for development and deployment. If you attempt to deploy Streaming applications with Java 21 or earlier, applications fail to open. Container builds for Streaming applications must include JDK 22 instead of Java 17.

On all supported operating systems, the TIBCO Streaming installation kit provides the runtime components of Eclipse Adoptium JDK 22.0.2 (formerly known as AdoptOpenJDK) in a subdirectory of the Streaming installation directory, for a private use to run Streaming program fragments and applications from within StreamBase Studio. As before, Streaming detects and prefers a system-installed JDK, and uses the bundled JDK as a fallback. See further details about the JDK requirements of this release in the JDK entry of the Supported Configurations page.

For this release, TIBCO Streaming uses Eclipse 4.34 (2024-12) instead of 4.28 (2023-06) as in the previous version.

Red Hat Enterprise Linux Server 9 is now a supported operating system for deployment.

Debian Linux version 12 is now a supported operating system for deployment.

Added a preference in the Authoring panel to change the EventFlow Canvas zoom behavior. The zoom behavior can be either Center of canvas (default) or Mouse location. For more information see, Authoring Panel.

StreamBase applications can now be launched through Project Explorer in Studio by right-clicking on the application archive and then selecting the option Run As>StreamBase Application.

A new property Exclude Input Tuple From Output Tuple is added in Decision Table operator. When checked, the Decision Table operator does not add an in output field with the same schema as the input tuple, and does not copy any input to the output.

Users can now configure a named ParameterSettingsGroup in the Parameters tab of EventFlow and LiveView launch configurations.

The output of DTM commands is shown in the Clusters view. To show the Command Output pane, select View Menu (3 dots) and then select Show command output. For more information, see Clusters View Toolbar.

Snapshot file created using epadmin create snapshot command is now written in the node install directory. Previously, it was written into the OS working directory.

Two new properties Avro Schema and Key Avro Schema are added in the Apache Kafka Consumer and Producer Adapters. For more information, see Kafka Producer Adapter Properties and Kafka Consumer Adapter Properties.

A new field is added to the Properties>General tab of Module Reference and Extension Point editors. It is called Module Description for ModRefs and Interface Description for ExtPts. It shows the module or interface's description specified in its Metadata tab, if any.

Two new parameters are added to the epadmin add container Command. For more information, see epadmin add container.

A new parameter javahome is added to the epadmin install systemservice command, specifying the location of the JRE or JDK to be used by the node.

For security reasons, endpoints no longer output stack traces by default. If requested by Support, customers must set liveview.suppress.error.detail=false.

Runtime performance statistics disk, network, sar, and vmstat can now be cleared.

LiveView alert rules are limited to a maximum of 1000 by default.

In version 11.1, the StreamBase Fragment Dependencies build path entry was removed. Starting from this release, the corresponding entry in the project's .classpath file will be removed automatically whenever a project's Maven configuration is updated.

LiveView Client now requires a newline before EOF or else the last line may not be published.

In the Kubernetes and local environment, the root URL of the dtm server now always redirects to /admin-ui. Previously, it was redirected to /help-ui(swagger-ui) in the local environment.

StreamSQL is removed from this release.

Starting this release, StreamBase Studio has removed the Subversion support.

Support for macOS is deprecated and will be removed in a future release.

H2 database is removed from this release. By default, LiveView metadata is now stored with SQLite.

There is no replacement for the C++ API and the client code must be migrated to one of the other supported language bindings such as Java, .NET, or Python operators.

The StreamBase Client API for Python 2.7, previously deprecated in Streaming 11.0, is now removed on all operating systems. This deprecation does not affect the LiveView Client Python wheel, the Python Operator, and the Python Instance Operator, which continue to be supported.

jsbc command line tool is now deprecated. The functionality of this command line tool is been replaced with epadmin and any use of this command should be migrated to epadmin.

sbadmin, jsbadmin, and sbc command line tools are now removed. The functionality of these command line tools is replaced with epadmin and any use of these commands should be migrated to epadmin.

TIBCO Streaming Admin operator is now deprecated. For more information, see Using the TIBCO Streaming Admin Operator (Deprecated).

The application configuration timers keepAliveSendIntervalSeconds, nonResponseTimeoutSeconds, nodeActiveTimeoutSeconds, and timeoutSeconds are now deprecated. The milliseconds counterparts of these timers are introduced. For more information, see Runtime Application Configuration.

The epadmin partition target commands define partition, disable partition, enable partition, migrate partition, and update partition are removed in this release. These commands were not exposed or documented.

macOS 12 is no longer supported on Streaming 11.2 version.

To upgrade to this version, clusters must be completely stopped and restarted. The node-to-node protocol changed in this release in a non-backward compatible fashion.

The Distributed Transactional Memory API changed between versions 10.x and 11.x, preventing an 11.x node from starting if there is an existing live 10.6 node already in the cluster. Instead, ensure that 10.x and 11.x nodes are in different clusters at all times.
