Regarding the WLM couple datasets, no we don't have a reason other than
the desire not to run with some production couple datasets, and some
specifically for DR.
Do you use your production logr couple dataset, or one specifically for
DR? If the latter how do you keep the two in sync since AFAIK you can't
add/change logger entries in a specific couple dataset, only the active one.

We provide our own DR between data centers with fully mirrored disk, but
we still handle couple data sets in a manner similar to yours. However, we
do not create new WLM data sets. Do you have a specific reason for doing
so? We (OS sysprogs) are caretakers of CFRM and logger policies, which can
be recreated before (CFRM) or immediately after (logger) the first IPL by
automated batch processes. But WLM AFAIK requires ISPF and manual
involvement by the performance/tuning group, who owns WLM policies. We've
never seen a need to tailor WLM for the DR environment.

Subject: Couple Data Sets - DR Considerations
Sent by: IBM Mainframe Discussion List<[email protected]>
We recover three sysplex's at DR, two single system sysplexes and one
multi-system parallel sysplex. Since we don't utilize any data
replication processes, we still perform DR via full volume backups and
restores using our providers floor system.
The two single system sysplexes use their production couple datasets at
DR, but we have a separate set of DR couple datasets for the parallel
sysplex that we populate at DR (mainly CFRM, LOGR, WLM, the others we
don't care about at DR).
Just wondering how everyone else is doing it.
