Hi Tony, I frequently use the procedure Gary mentioned which results in a formatted dump. I suspect IPCS might be overkill, but I don't know your situation. I'm sure folks exist who cut the teeth on MVS dump reading by starting out with unformatted dumps and IPCS, but I don't know of any. The formatted SYSUDUMP is pretty straightforward.
If you have any questions, there is a section in the chapter on ABEND dumps in this manual... https://www-01.ibm.com/servers/resourcelink/svc00100.nsf/pages/zOSV2R3ga320905/$file/ieav100_v2r3.pdf The zap utility mentioned is also in there if you need it, and called SPZAP.

This message was sent from outside your organization. When I add a DC X'0000' and I force a SOC1, I don't see any dump added to IPCS. The guy that set up this system is gone. I don't know if he did 'something' to prevent dumps.
