Reacting to an Event in a Sysplex Environment

Messages are often sent to all members (systems) in the Sysplex environment. Control-O can react to a message originating in any system in the Sysplex environment.

To trigger a rule that responds to a message that originated in another system (or an event that sends out a corresponding message), specify a SYSTEM value in the ON statement (valid for ON JOBARRIV, ON JOBEND, ON MESSAGE, and ON STRING).

Note: If the triggering message originated on another computer in the Sysplex the JTYPE subparameter is treated differently. Because reissued messages are handled by the CONSOLE address space, a rule on another computer will be triggered only if the value of the JTYPE subparameter is either blank (the default) or S.

Explanation

The above rule is triggered when the CICS job is ended in the MVS1 system.

The %%$REISSUED System variable is used to determine whether or not the CICS job ended in the current system.

• If the job was ended on the current system, a message is sent to the operator indicating that CICS was ended.
• If CICS was ended in another system, CICS is started in the current system.
