Shutting down the CSL RM

Before shutting down a Resource Manager (RM), consider the reasons for shutting down and how shutting down RM can impact other IMSplex members. There are multiple ways to shut down RM.

Recommendation: Shut down RM by shutting down the CSL as one unit.

To shut down the RM, do one of the following:

The system operator can use a z/OS® STOP command: P rmjobname
rmjobname is the job name of the RM address space to stop.
Issue the CSL SHUTDOWN command.
Issue the CSLZSHUT request.

If no clients are connected to RM and no IMSplex-wide process steps are in progress (or no IMSplex-wide processes are in progress for an RM with no resource structure defined), RM shuts down. If clients are connected to RM, message CSL0300I is issued, and RM quiesces in-flight work. RM waits for process steps to timeout and returns the process step responses to RM clients.

For an IMSplex defined with no resource structure, RM terminates any IMSplex-wide process that is in progress and issues message CSL2210I for each terminated process. To avoid this premature termination of the process, complete all IMSplex-wide processes before RM shutdown is attempted.

If the IMSRSC repository is enabled, RM termination disconnects from any repository RM is managing and deregisters from the Repository Server (RS) address space.
