As can be seen from the replies, there are different approaches for handling
the PTS. In my shop, when a z/OS release is installed, the PTS is placed on a
volume where it will have plenty of room. For the life of the install, PTFs
are not purged from the PTS - ever. If necessary, spill PTS datasets are
defined. We are not a large shop, and this works for us.
For ACCEPT, we generally run the ACCEPT of previous service just before
beginning the next maintenance cycle.
1. Size of the shop is loosely related to the size of PTS. I would say
more: in a large shop there's more chance to get additional disk space
for PTS.
2. People consider ACCEPT process as dangerous, they are reluctant to do
ACCEPT. What about APPLY? There are PTFs which cannot be simply RESTOREd
(HOLDSYS DELETE) and the RESTORE itself is cumbersome. IMHO the best way
to move back is to have copy of system volumes (including RES, DLIB and
SMPE). In such scenario there is no big thing to ACCEPT older PTFs.
3. Last, but not least: sometimes ACCEPT is simply required.
Sometimes a product reads from DLIB libraries. IMHO it's plain wrong,
but it happens. Someone mentioned IMS as such product, I vaguely
remember something else.
Another example: fmid H09F210, COBOL and CICS Command Level Conversion
Aid (CCCA). It is distributed with error in SMP/E description (wrong
RMID). Recommended solution includes ACCEPT.
