Re: determine v5r4 ptf level

be careful of this option especially if the system is "PTFless"

I seem recall there were some PTF's to help in the applying of PTF's and therefore may require two IPLs.

I wish I could recall the specifics, but I think they were outlined in the CUMe PTF install doc.

Please read that doc before starting.

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.
