jsbc

< Previous		Next >

DESCRIPTION

jsbc runs a Java implementation of the StreamBase client utility, which lets you send requests to a running streaming node. For example, the jsbc list streams command requests the server to list available streams.

OPTIONS

With a few exceptions, the jsbc command has the same options as the sbc command, as described in sbc(1). The exceptions are:

No space after -u or -p

For jsbc, there must be no space between -u and the following URI, and no space between -p and the following port number:

jsbc -usb://localhost:10000 listConnections
jsbc -p9900 listConnections

Important

When communicating over an SSL connection, substitute sbs: for sb:

-J option supported

The jsbc command accepts the -J option, but sbc does not.

-Jjvm-option

Specifies a system property setting or other JVM argument to be passed to the JVM that runs this jsbc command. Use this option to specify temporary settings that affect only the current invocation of jsbc. 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 jsbc.

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

To use jsbc to communicate over SSL connections, you need to configure access to the local trustStore for command-line Java utilities in this manner, substituting actual filenames and passwords (line breaks added for readability):

jsbc -J-Djavax.net.ssl.trustStore=C:/Temp/client.keystore 
     -J-Djavax.net.ssl.trustStorePassword=cl123abc 
     -J-Djavax.net.ssl.keyStore=C:/Temp/client.keystore 
     -J-Djavax.net.ssl.keyStorePassword=cl123abc 
     -usbs://localhost:10002;user=bob;password=secret deq OUT

Use sbs instead of sb in URI when running with a proxy server

For example, the following command connects to a proxy using Encrypted StreamBase Network Protocol over sbs:

jsbc -u"sbs://proxyhost:port;user=theuser;password=123abc" enq InputStream

No arguments for -h and --help

Unlike the sbc command, this jsbc command's -h and --help options do not take subcommand arguments.

COMMANDS

The jsbc command accepts the same subcommands as the sbc command. However, note that sbc does not support Encrypted StreamBase Network Protocol. See sbc(1).

FILES

There is no configuration file for jsbc.

ENVIRONMENT

STREAMBASE_SERVER: 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.
STREAMBASE_RETITLE_TERMINALS: Optional. If set to any value, StreamBase programs assign a terminal window title to match the name of the executable being run. By default terminal titles are not affected. Applies to jsbc dequeue and jsbc enqueue only.
