Sets the data rate for this feed simulation to run as fast as possible.

Changes the maximum number of tuples to buffer on each stream to count, when using the default load or a user-specified distribution. This setting adjusts the enqueue client buffer size for each input stream. The default size is 100 tuples. Specify zero to disable buffering.

Changes the maximum number of tuples to buffer when using a data file or JDBC data source. The default buffer in these cases is 40,000 tuples.

Converts a legacy feed simulation file (saved with StreamBase 3.5 and earlier) to the current feed simulator XML format, and prints the result to standard output. You can redirect the converted results to a file, as in the following example:

sbfeedsim -c MyOldFeedsim.sbfs > MyNewFeedsim.sbfs

When using a data file or JDBC data source, completely prefill the tuple buffer before sending the first tuple.

Run this feed simulation even if warnings occur during application compatibility validation.

Displays usage text, then exits.

Specifies a system property setting or other JVM argument to be passed to the JVM that runs this sbfeedsim command. Use this option to specify temporary settings that affect only the current invocation of sbfeedsim. You must specify multiple -J options to specify multiple JVM arguments.

A space between the -J and its argument is optional. Use the full option syntax for jvm-option that you would use at the Java command line, including the initial hyphen. For example, specify -J-Dstreambase.log-level=2 to increase the log level for this invocation of sbfeedsim.

Your jvm-option argument might require surrounding quotes, depending on the characters it contains and the shell you are using. However, do not use quotes to escape the spaces between separate JVM arguments; instead use separate -J options. For example: -J-Xms512M -J-Xmx2G

Force an on-the-fly conversion and execution of a feed simulation file created with StreamBase 3.5 or earlier.

Limit the feed simulation run by time. Generates data appropriate for the schemas of the input ports of the running StreamBase Server, until secs seconds have elapsed.

Limit the feed simulation run by number of tuples sent. Generates appropriate data as above up to the number of tuples specified by count.

Sets the port number for the StreamBase Server instance to connect with. This is useful when the server is localhost and you only need to specify a non-default port, instead of specifying the full URI with the -u option. The default port is 10000.

Does not display tuples (quiet).

Specifies a comma-separated list of input stream names in the application running on the connected StreamBase Server. The -s option is only valid when no .sbfs feed simulation file is specified as an argument.

Specifies the URI of the StreamBase Server to communicate with. The default is sb://localhost:10000/. The URI can also be set using the STREAMBASE_SERVER environment variable. See the sburi page of the Reference Guide (or see sburi(5) at the UNIX shell prompt) for a discussion of the URI format and its shortcuts.

Speeds up all streams by a factor specified by factor. For example, -x 2 runs the feed simulation at twice the default speed.

Specify a long value for seed to be used as the random value generator's seed, when automatically generating values for each field in each stream. Without this option, sbfeedsim uses zero as the seed. The values generated by sbfeedsim are the same for a given seed value, which makes tests with the same seed value repeatable. Specify a seed value other than zero to generate a different set of values than the default setting.

Prints version information and exits.

Optional. Contains the URI for a StreamBase Server instance. Use this variable to set a default StreamBase URI for certain StreamBase commands that take the -u option. For example, sbc status honors the variable, but sbc list does not. If set, commands use the URI in this variable. If this variable is set, you must use the -u option to communicate with any server other than the one specified in this variable. You can set a comma-separated list of URIs in the variable, and commands such as sbc status returns status for all listed servers. However, sbc list returns information only for the first listed server. See the sburi(5) page in the Reference Guide for more on StreamBase URIs.

Optional. If set to any value, StreamBase command-line utilities assign a terminal window title to match the name of the executable being run. By default terminal titles are not affected.

When you have saved a feed simulation file that specifies data generation from a JDBC data source, you can run that file with sbfeedsim. For this to work, the JDBC driver JAR file must be in the classpath. You can set the CLASSPATH environment variable, or use another standard classpath setting method. If you use the CLASSPATH environment variable, append to the existing classpath the full path to the JDBC JAR file. See Feed Simulation with a JDBC Data Source for further information.
