Sending commands to the IMSplex

After setting up an IMSplex, you can issue commands using the TSO single point of control (SPOC) interface.

You can also write an automated operator program that can issue the same commands. The TSO SPOC provides integrated online help.

The IMS™ Application Menu provides a common interface to enable you to start applications such as TSO SPOC, Syntax Checker, IVP, and more.

Important: SPOC applications (including the TSO SPOC and the Batch SPOC utility) issue the CSLOMCMD request. You therefore need to be aware of the parameters and return and reason codes of the CSLOMCMD request.

If you write automated programs, those programs must include logic to handle the responses from the commands; the automated programs have to parse the XML statements.

Most commands that are issued to an IMSplex are issued to OM. The exceptions are:

BPE commands, which can be issued directly to CSL members and to CQS.
The SHUTDOWN command, which can be issued directly to SCI to shut down one or more CSL members.
Query requests issued by a z/OS® master console to the CSL.

In an IMSplex, the format, behavior, and responses to certain IMS commands have changed. Some IMS commands are no longer recoverable; others are not supported in an IMSplex. Some commands are supported only in an IMSplex.
