Define the IBM MQ subsystem to a z/OS WLM service class

To give IBM MQ appropriate performance priority in the z/OS system, we must assign the queue manager and channel initiator address spaces to an appropriate z/OS workload management (WLM) service class. If we do not do this explicitly, inappropriate defaults might apply.

  • Repeat this task for each IBM MQ queue manager.
  • You do not need to perform this task when migrating from a previous version.

Use the ISPF dialog supplied with WLM to perform the following tasks:

  • Extract the z/OS WLM policy definition from the WLM couple data set.
  • Update this policy definition by adding queue manager and channel initiator started task procedure names to the chosen service class
  • Install the changed policy on the WLM couple data set

Then activate this policy using the z/OS command 

V WLM,POLICY=policyname,REFRESH

See ../pla/q005930_.htm for more information on setting performance options.
