RE: Cume PTF

The system is at a hospital. There are downtime procedures that rae used when vendor software version upgrades are applied - a process that can easily take ten hours or more.

The SA is anti-social. I managed to apply a PTF that fixed a QSH error described by Scott Klement. Didn't require an IPL and did not require explaining to the SA.

I worked on a B50 years ago. PTFs weren't applied regularly then either. But, more often than yearly. Had to "justify" (explain how something would be better). Maybe same thing where I am now.

Link Loader errors are usually caused by specific problems, like co-dependant PTFs that are not applied at the same time. If you install complete packages (cume or group) delayed with an IPL and don't have any test PTFs applied you'll probably never have a link loader error. Applying packages on a regular schedule (like 2 or 4 times a year) will do wonders as far as minimizing these kinds of problems. Systems requiring 24x7x365 uptime are harder to deal with.

C8305540 would have been released on the 305th day of 2008 so it's approx. 2 years old. Applying a more current cume for V5R4 might be the prudent thing to do.

Not my responsibility, but the thread concerning WRKPTFGRP made me a tad curious. Last cum applied is C8305540. Is there some magic way to know if a cum can be applied successfully - no link loader error, for example?
