Task 8: Define the WebSphere MQ subsystem to a z/OS WLM service class

 

• Repeat this task for each WebSphere MQ queue manager.

• You do not need to perform this task when migrating from a previous version.

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

Use the ISPF dialog supplied with WLM to

• 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 WebSphere MQ for z/OS Concepts and Planning Guide for more information on setting performance options.
