Re: Permanently apply PTF's before V7R1 to V7R3

When you put the required upgrade MF PTF's on do this
(assuming optical image catalog)
INSPTF LICPGM((*ALL)) DEV(OPTVRT01) INSTYP(*DLYALL)
follow that by
APYPTF LICPGM(*ALL) APY(*PERM) DELAYED(*YES)
Then do just one IPL.

Definitely apply all PTF's permanently prior to an upgrade. Otherwise the
phantom crap will remain forever and you'll have to manually clean it all
up. Been there, done that.

Picture this scenario. You're at 7.1. You put PTF SI12345 on. It
upgraded QCMDEXC.PGM. As part of that process you start out with
QSI12345.SAVF. When you apply that PTF the first thing it does is back up
the old QCMDEXC.PGM into another save file, let's say QSI12345A.SAVF. This
way if you want to remove that PTF it can restore the old QCMDEXE.PGM.
When you apply that PTF permanently it will delete the back up save file.
If you upgrade your OS without ever applying that PTF permanently first
that QSI12345A.SAVF will remain on your system for all time. Had a bunch
of these from V1 days on.

These cover letters will be around for ever if you do not permanently
apply them. But these are much easier to clean up. (see option 4).
