Shutting down the CSL OM

Before shutting down an OM, consider the reasons for shutting down and how shutting down OM can impact other IMSplex members.

Recommendation: Although you can shut down OM by itself, you should shut down OM by shutting down the CSL as one unit.

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

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

If no clients are connected to OM, the OM shuts down. If clients are connected to OM, message CSL0300I is issued, and OM quiesces in-flight work. After all work is quiesced, the OM address space terminates.
