Authority

You do not need any authority to run this command.

Description

The command provides the following information about your product, version, and environment:

  • Version: Specifies the Streams product version that is installed.
  • Product name: Streams
  • Build: Specifies the build date for your product. In general, this information is useful only to IBM Support.
  • Architecture: Specifies the operating system architecture. For example, x86_64 represents an Intel x86_64 (64-bit) environment and PPC_64 represents a PowerPC (64-bit) environment.
  • Operating system (OS): Specifies the operating system and distribution information. For example: 
    Red Hat Enterprise
Linux Server release 5.6
  • Operating system version (OS.VERSION): Specifies the version of operating system or distribution. For example: 5.
  • Operating system patch level (OS.PATCH): Specifies the patch level of the operating system version. For example: 6
  • Edition: Specifies the product edition. For example: Developer.
  • Edition name: Specifies the specific Streams product edition that is installed. For example: 
    Streams for Non-Production
Environment
    .

The command returns information about the product that is installed in the path that is specified in the STREAMS_INSTALL environment variable. If you have multiple versions of Streams installed, the command does not return information about all of the versions.

Options

--embeddedzk

Specifies to use the embedded copy of ZooKeeper. This option is not supported within the interactive streamtool interface.

If you are not using the interactive streamtool interface and you do not specify either this option or the --zkconnect option, Streams uses the ZooKeeper connection that is associated with the active domain or the domain that is specified in the --domain-id option. Streams determines which connection maps to the domain by using cached information about the domains. In this scenario, if the domain identifier is not unique in the Streams configuration cache, the command fails.

-h,--help
Specifies to show the command syntax.
--trace <level>
Specifies the trace setting. The following valid levels are listed in order of increasing verbosity, which is to say that the first level in the list generates the least amount of information:
  • off
  • error
  • warn
  • info
  • debug
  • trace
The default value is off.
-v,--verbose <level>
Specifies to provide more detailed command output. The verbosity level can be 0-3, where 0 disables detailed reporting and each increment provides more detailed output.
--zkconnect <{<host>:<port>},...>

The name of one or more host and port pairs that specify the configured ZooKeeper servers. This option is not supported within the interactive streamtool interface.

If you are not using the interactive streamtool interface and you do not specify this option, Streams tries to use:

  1. The --embeddedzk option
  2. The value from the STREAMS_ZKCONNECT environment variable
  3. A ZooKeeper connection string that is derived from cached information about the current domain.
