We have a few rules about PTF handling which have served us well for the
last 8 years.  Here's a quick rundown:

1)  Wait at least 2 weeks after a cume comes out before applying it, making
sure that IBM has not withdrawn it or marked any of its PTF's defective.
2)  Only permanently apply PTF's when IBM specifically says to do it
(release upgrades, etc.).  This takes a little extra DASD space, but
otherwise makes no difference in system performance, and allows PTF's to be
removed if they need to be.  If they're permanently applied, you can either
wait for a fixing PTF to supersede the defective one, or re-install the
operating system (!!!).
3)  Watch for HIPER PTF's, and make sure applicable ones are ordered and

Don't worry about IPLSRC B, it's normal to run from there.
