Task 2: APF authorize the WebSphere MQ load libraries

Search Tips   |   Advanced Search

 

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.

The WebSphere MQ load libraries...

thlqual.SCSQAUTH
thlqual.SCSQLINK

...must be APF-authorized. You must also APF-authorize the libraries for your national language feature...

thlqual.SCSQANLx
thlqual.SCSQSNLx

...and for the distributed queueing feature...

thlqual.SCSQMVR1

However, all load modules in the LPA are automatically APF-authorized. So are all members of the link list if the SYS1.PARMLIB member IEASYSpp contains the statement:

LNKAUTH=LNKLST

LNKAUTH=LNKLST is the default if LNKAUTH is not specified.

Depending on what you choose to put in the LPA or linklist you might not need to put the libraries in the APF link list

You must APF-authorize all the libraries that you include in the WebSphere MQ STEPLIB. If you put a library that is not APF-authorized in the STEPLIB, the whole library concatenation loses its APF authorization.

The APF lists are in the SYS1.PARMLIB member PROGxx or IEAAPFaa. The lists contain the names of APF authorized z/OS libraries. The order of the entries in the lists is not significant. See the MVS Initialization and Tuning Reference manual for information about APF lists.

If you use PROGxx members with dynamic format, we need only issue the z/OS command...

SET PROG=

...for the changes to take effect. Otherwise, if you use static format or IEAAPFaa members, IPL your system.
