Re: PTF Rollback Ideas

You don't mention what type of PTF's that they were, cume, groups, etc.
Have you been able to narrow it down or not really based on your number of
127. Did you apply these to any lower environments first and test with
them, did you see the same results. You also didn't mention what the
vendor is doing about the problem. In the article below they don't mention
using RMVPTF.

There is this if it helps.

Recently made the mistake of applying some PTFs that had not yet been
vetted by our vendor (I'm, lucky if they vet a CUME per year these days)
and have now had two weeks of production impact with what appears to be
slow record lock releases. I'm in limbo between IBM and my vendor at the
moment as IBM has now decided it's probably an issue in the vendors code,
however, they keep focusing on some SQL action that isn't part of the
problem. The problem is two RPG programs where program 1 updates a record
and then calls the next program to do another update to the same record.
This worked fine until I loaded some group PTFs.

All that preamble to get to my question. I want to roll these off. It's
been probably 20+ years since I've had to back off PTFs and never about 127
of them to roll it all back. Is there any kind of automated way of
determining the right/best sequence for unrolling them? Anybody had to do
this in recent years?
