Task 12: Update SYS1.PARMLIB members

 

• You need to perform this task once for each z/OS system where you want to run WebSphere MQ.

• If you are using queue-sharing groups, ensure that the settings for WebSphere MQ are identical on each z/OS system in the sysplex.

• You might need to perform this task when migrating from a previous version. For details, see Migrating from a previous version.

To ensure that your changes remain in effect after an IPL, update members of SYS1.PARMLIB as follows:

1. Update member IEFSSNss as described in Task 5: Define the WebSphere MQ subsystem to z/OS.

2. Change IEASYSpp so that the following are used when the system is IPLed:

   • the PROGxx or IEAAPFaa members used in Task 2: APF authorize the WebSphere MQ load libraries

   • the LNKLSTkk and LPALSTmm members used in Task 3: Update the z/OS link list and LPA

   • the SCHEDxx member used in Task 4: Update the z/OS program properties table

   • the IEFSSNss member used in Task 5: Define the WebSphere MQ subsystem to z/OS
