RE: determine v5r4 ptf level

Be very careful with this advice. I've seen systems get hammered with a
broken link loader if one tries to do too much in one pass.

There are also pre-reqs and co-reqs that might need to be permanently
applied before putting on certain ptf's.

Steve--

You can load all of the PTFs and mark them as "delayed" and "automatic IPL
N"-- and that can happen without bringing down the system. The next IPL
will apply the PTFs (and take more time than normal), but that minimizes
downtime. This does take disk space to hold the PTFs...

If you actually have a cumulative PTF, plus hipers, plus groups, plus what I
call 'stray' PTFs (the ones you order because you know you need them),
chances are a lot of the PTFs will actually be duplicated. The install
process will say, "I've already loaded that one" and go on to the next. So
a stack of DVDs may not be as scary as it looks!

If you did have PTFs applied you could have gained some space by applying
all the PTFs *PERM. When a PTF is applied *TEMP, the old version of the
PTFd code is kept on the system so you can un-apply the PTF. Applying the
PTFs *PERM throws away that previous copy.

Turns out the system I am working on has no PTFs applied. ( In the defense
of the person here responsible for it, he has a stack of DVDs to load.
Looks like an all day, system down process. )
