Task 12: Update SYS1.PARMLIB members
To ensure that your changes remain in effect after an IPL, you must update some members of SYS1.PARMLIB
- You need to perform this task once for each z/OS® system where you want to run IBM® MQ.
- If you are using queue-sharing groups, you must ensure that the settings for IBM MQ are identical on each z/OS system in the sysplex.
- You might need to perform this task when migrating from a previous version.
Update SYS1.PARMLIB members as follows:
- Update member IEFSSNss as described in Task 5: Define the IBM MQ subsystem to z/OS.
- Change IEASYSpp so that the following members are used when an IPL is performed:
- the PROGxx or IEAAPFaa members used in Task 2: APF authorize the IBM 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 IBM MQ subsystem to z/OS
