This is part of the larger task of customizing your z/OS environment.
If you are running z/OS in Workload mode, change the classification rules to add the started task names of the brokers, User Name Server, and Configuration Manager to the Started Task Control (STC) subsystem types, for example MQP1BRK, MQP1UNS, and MQP1CMGR to the OMVS subsystem types.
SUBSYS=STC .. TRXNAME=MQP1BRK,PGN=35,RPGN=2010 .. SUBSYS=OMVS .. TRXNAME=MQP1BRK%(1),PGN=35,RPGN=2011 ../* Broker address spaces*/The %(1) represents jobs beginning with MQP1BRK with one character following it. Define the priority of the broker lower than DB2 and WebSphere MQ.
