Pete,
There was an issue with 5761JV1 PTFs when upgrading from V6R1 to V7R1.
Old PTFs related to Classic Java, which was deleted with V7R1, remained on the system in *SAVF status.
PTFs had to be manually deleted.

Rob,
I always apply PTFs permanently before an OS Upgrade as well, but I always apply PTFs perm after they have been on the system for a while. Basically before I put the next cumulative on, I apply everything permanently. This is especially important for the MF PTFs on 57xx-999, as it means that what is currently on the B side (of LIC), now is on the A side. So, if applying new 57xx-999 PTFs from the cume (which will always have new MF PTFs) and you put on a bad MF PTF which prevents you from IPLing, you could just IPL from the A side which would be the LIC (License Internal Code) that you were running right before the update.
I have never seen PTFs *SAVF remain after an upgrade, but then again I always apply my PTFs perm as that is the right way to do it. So, I can't say that those objects would remain.
Pete

There are pros, and cons, to permanently applying PTFs. General rule of thumb is to permanently apply all PTF's before an OS upgrade. Failure to do so will leave many orphan objects on your system for all eternity. For example, let's say ptf SI12345 fixes program QSOMETHING. When you put on ptf SI12345 IBM backs up the original program QSOMETHING into a save file and leaves it on your system. This way, if you remove that ptf, it can restore it from that save file. When you permanently apply SI12345 it deletes the save file containing the original QSOMETHING. If you've ever watched your IPL during a PTF apply and saw "5000 objects processed"
during the apply of one ptf, you start to realize how significant these ptf save files can be.
The main con is, if you want to back one PTF off. It gets to be rather tough, if it's permanently applied. Normally not something you do if you've been running that PTF for a few months.
The exception that proves the rule is Domino. I never permanently apply PTF's to Domino unless I am getting ready to remove that version of Domino. It is quite often that I have to remove one fix to apply another.
Therefore a Domino shop should probably avoid the APYPTF LICPGM(*ALL) approach. Do them one by one.

"Generally I do like load and run Temp and SAVE 22. Run for perhaps 2 or
3 months. Then perm apply all and SAVE 22. Then repeat as necessary."
This brings up a question I have and am interested in what others do.
Currently immediately before applying a new CUME I apply the 5770999 PTFs permanently. Someone asked if maybe we should apply all PTFs permanently prior to applying a CUME. Is there a reason to apply all other than having a base level of PTFs?

I do a LOT of PTFs and spoken to many of the fine folks at IBM re PTFs and the process.
First off it has been stated that MANY PTFs simply require an IPL. The objects being replaced simply cannot be updated at any other time as they are always in use or otherwise locked. A claim of 90% of PTFs can be applied immediately doesn't align with what I see. I suppose it's possible in fact but with all the pre and co requisite PTFs all it takes is one PTF in the 'set' to require an IPL and the other PTFs are stuck so effectively all the PTFs require an IPL.
I have heard several times that using *IMMDLY (Immediate if possible, Delayed to IPL when mandatory) Is NOT recommended for any PTF Groups including CUMEs. It's essentially impossible to read every cover letter and deal with all the special instructions. Failure to follow the special instructions can mean many things, not the least of which is that many of the PTFs that APPEAR to be applied are not active until an action is taken, frequently the action is to IPL (which I find annoying!)
I do concur with other comments that if you are not provided sufficient time for backups, PTFs, and other maintenance then having an HA system is near mandatory. Clearly NOT doing PTFs and proper saves is just a system crash looking for a bad time to occur. If time is so short when you DO get a window that any problems push you into being considered an outage that also is 'living on the edge'. Also consider making your load source disk an SSD, this will 'enhance PTF apply performance.'
Generally I do like load and run Temp and SAVE 22. Run for perhaps 2 or
3 months. Then perm apply all and SAVE 22. Then repeat as necessary.

HA/DR Is out of the question.
Currently, I try to IPL Production every 2 months for PTF apply along
with a system save.
The IPL and system save will probably go to 6 months or as needed.
90% of PTFs can be applied immediately without an IPL, however IBM
does
not recommend immediate apply for more than a single PTF.
Applying a large amount of PTFs immediately has caused issues in the
past.
Permission has been granted for the PTF immediate apply, but I'm weary
from previous issues.
Any thoughts from the group.
Thank You
