RE: Perm. apply PTF's thoughts

I strongly agree with the RCLSTG idea.  We do them twice a year (again, more 
for housekeeping than anything else) but also do them the week before an 
upgrade to the OS, disk or related hardware, or the CPU.

My 2¢:

Back in the days of V3R1 to V3R2 upgrades many people had issues with not 
having enough temporary storage to complete their upgrades and you absolutely 
could not upgrade without perm applying all PTF's.  I have not seen this occur 
since.

The thought of having to slip the LIC or O/S to remove a PTF that has been perm 
applied and needs to be removed keeps me from perm applying anything that does 
not require it.  A former employer's policy was to perm apply all PTF's at 
every IPL and I argued (futilely) against that until it finally bit us.  If you 
keep fairly current on cume packages you should not need to get current before 
upgrading.  I usually apply new cumes to my test system within 30 days of 
release(just long enough to verify defectives) and then to my prod systems a 
month or two later.

I do keep the PTF save files cleaned up, though that is more of a housekeeping 
issue than a space issue.  I also will not consider doing an upgrade without a 
RCLSTG first, this can take a while but unless you don't mind doing your 
upgrade twice I highly recommend this step.

subject: Perm. apply PTF's thoughts

Folks,

Historically, I've been remiss about permanently applying PTF's. Originally, my 
thought process was that normally you see it as an item on new releases with 
corresponding instructions to clean up disk space.  I've never had storage 
problems around new release installs so I have forsaken that process in the 
name of time.

I'm beginning to wonder how wise that is.  Doesn't that leave some potential 
for PTF *SAVF's and other objects (potentially IFS) out there for cleanup?  And 
couldn't those objects be in many different places on the system (QSYSDIR, 
QIWS, QDNS, stream files in IFS directories, etc)?  What do other people do 
with regards to perm apply of PTF's?  Do you think it is easier to perm apply 
PTF's prior to a new release as opposed to cleaning their tracks later or never?
