Re: Perm vs Temp PTF applies

So this temp vs perm thing. Much FUD and such here.

First you cannot NOT apply PTFs perm, it's just not possible. Jim and others have already pointed this out. In MANY cases (ALL?) where there is a PTF being temp applied that supersedes the previous PTF that previous PTF is Perm applied. In addition all PTFs that the old PTF has as a pre-req or co-req are also permanently applied. So this happens for this reason all the time.

Then there is the Technology Refresh. Basically when you apply the enabling LIC PTFs for a TR which are the MF99xnn PTFs, (here nn is the TR number and x is 0 for i 7.1, 1, for i 7.2 and 2 for i 7.3) the system will perm apply all the PTFs in the LIC. This is because basically that MM99 guy will supersede pretty much the entire LIC. So that happens too.

Then there is the disk space that has been talked about. Temp applied PTFs consume space. Now I sell disk space so use all you want but if you don't want to waste it, do some perm applies.

Then as Steve mentioned if the difference between the A LIC and the B LIC are so vast you could find yourself unable to even run on the A side. This was a bigger problem previous to the TR because the TD at least forces them equal a couple times a year.

Now if you want to do your PTFs smoothly and just stay out of trouble you WILL Perm apply. This sort of sequence:

DoUntil Upgrade *eq *YES

FULL SAVE
Load/apply PTFs
SAVE IBM

Run for a while (Your call, month or two perhaps)

APYPTF *ALL *PERM
IPL
SAVE IBM

Run for a while (your call, month or two perhaps)

Enddo

Follow this pattern and you and your system will be happy and applying PTFs will run smoothly with near zero issues.

So I've run across something interesting. I was talking with someone about applying the latest cume / group PTF on a V7R1 server that has not had PTF's applied in over 3 years. When I asked if the existing PTF's had been perm applied, the response I got was that they never apply the PTF's perm but keep applying temp.

Does anyone else do this? I've always done the apply cume temp, let it bake until the next pack comes out, apply perm before SAVSYS (at least), then apply next cume pack.

Is this not the way of PTF care and feeding?

Thanks
