SADMP z/os

Postby jaggz » Fri Sep 06, 2013 3:15 pm

Hello,

Apology for my ignorance. Does Z/OS SADMP fills the CSECT Field to locate the Module which were responsible for Z/OS outage ? Precisely I am trying to understand if Z/OS SADMP produces the diagnostic reports ?

Regards,
Jaggz

By SADMP, do you mean the z/OS standalone dump? If so, the answer is no, it just produces a binary image of the system and page data sets on a disk data set or magnetic tape.

Thanks. When we say the recurrsive abends have occurred pointing to a module IEANUC01.IGC003. Can we identify in which CB(Control Block) the storage have been wrongly overlaid ?

Possibly.

Do be aware that what you see may be a "victim" rather than the "culprit". Often these things take a while to fall over due so something earlier on.

What is running that causes the abend? You might consider putting some "footprints" in the code to learn where the code has gone before the problem occurrs.
Hope this helps,

Mr. Scherrer is most likely correct. IGC003 is "exit," and it touches quite a lot, plus it's entered for a variety of reasons. There is a very good chance - close to 100% in my opinion - it's a victim of some wrong doing higher up the food chain.

What you (or most likely IBM) have to do is determine (IBM) or guess (you) what it was trying to do when it broke. That might give a clue as to who the real culprit is.

Good luck.

Hello All,

Thanks. After some analysis it looks to be an overlay on save area of Nucleus.
