Health check: WLM classification for OMVS components.
A step in the control region start-up procedure, invokes the applyPTF.sh
script, using BPXBATCH. Because the BPXBATCH program is classified
according the OMVS rules, on a busy system several minutes might pass
before this step is completed.
You can minimize the impact of the BPXBATCH step by changing the WLM
Workload Classification Rules for OMVS work to a higher service objective
(Example 14-4).

14.9.5 Address Space ID reuse
Address Space ID (ASID) reuse is an operating system function, introduced with
z/OS 1.9. It allows the reuse of Address Space ID’s, including those that are
associated with cross-process services (like TCP/IP), which could not be reused
in earlier releases of z/OS. WebSphere Application Server for z/OS, starting with
V6.1 is able to use this function, thereby allowing the reuse of the ASID for
terminated control regions.
