Re: GO Save Option 21

Permanently applying PTFs prior to the upgrade continues to be important
due to DASD considerations.

You may have temporarily applied PTFs which contain Integrated File System
stream files and these stream files will not be automatically removed after
the upgrade (as opposed to PTF save files which generally are removed if
you are using Operational Assistant Cleanup support for system journals and
system logs).  In some cases this has represented a significant amount of
DASD being tied up unnecessarily.

Starting with upgrades FROM V5R3 the system will remove stream files
associated with V5R3 and later PTFs but as you are upgrading TO  V5R3 these
stream files associated with prior release PTFs will continue to exist on
your system.

Even after going to V5R3, and the above consideration no longer applies, it
will still be important to permanently apply (or remove) temporary PTFs in
case errors occur during the upgrade process making certain PTF control
information no longer accessible to the system (preventing cleanup in some
situations).

That looks like the plan right now. We're planning our upgrade to V5R3, and
I always like to get a 21 save before. Just in case. Plus my boss insists
on applying all of the PTFs *perm before the upgrade. I don't think it's
necessary any more, but I do what I'm told.

Thanks,

Mark
