Reading DUMP.
Reading DUMP.
Hi,
If I need to learn the reading a "raw" dump - where to start with? (I meant not a formatted dump or so)

Re: Reading DUMP.
You have the PSW, you have the registers, you have the dump. Everything you need to get started. Application program? System program? Vendor program?
Re: Reading DUMP.
Thanks William.
I know there is Process status word and that will have the address to last instruction but than that is all I know. What to do next? The IBM Documentation is more or less, helpful when you "know" a bit already. I'm just starting with it.
I'd like to start with Application Programs first.

Re: Reading DUMP.
Dump reading is more of an art than a science -- there is no cookbook, step-by-step, approach that anybody can give you to learn how to read a dump. The wide variety of system abends that cause dumps means that a generic approach doesn't work. Your best bet is to get some dumps and figure out what the problem is from the dump.

http://publibz.boulder.ibm.com/cgi-bin/ ... s/ez2dgz50 - The z/OS Diagnosis Bookshelf is a good site to bookmark. If you need to get into the task control blocks, those are mainly in the 6-Volume "MVS Data Areas" books (GA32-0853 through GA32-0858).
