Hello,

To get help you will probably need to provide much more info. . .

How often does this happen? Did this ever work correctly? If yes, what was changed?

Do other similar processes work correctly? If yes, see what is different between the ones that work and this one.

Do you know at what place in the code the problem happened? If not, you may want to add some diagnostic code to help identify where in the code the problem occurs.
Hope this helps,
d.sch.

How did you get on with this? You have two "DFS" messages to look up, google can find them in a flash.

Something has abended (helpful, aren't I :-) ). Module "unknown" and an S0C4. Look at the dump(s) produced. My wild guess would be something has overwritten some program code. With the dump, you can do better than my wild guess. From the PSW see what was supposed to be being executed. Find the module it was within (if it is all Cobol (and not crashed in an IMS routine), just look backwards from the failing address until you find a Cobol program). If at the failing address it is all space (or low-values, or high-values, or a repeating pattern, or something that is obviously data not program code, which is what there should be where you are looking) then my wild guess came in. If not, you have the dump and the program listings. We'd need more information for more advice.

In this sort of error, the whole of IMS goes down and has to get restarted. Work on the dump, it is a bit of a pain bringing down an IMS region just to see some displays.

IMS hasnt abended S0C4 - CICS has
The application had issued a DL/I call that hadnt completed
IMS recognises a dependednt region (CICS) has gone while in DL/I so abends U0113 to force BO on ERE
Why did CICS abend?
If the code hasn't been changed, why is the LKED date today?

We have an IMS DBCTL connecting to 4 CICS regions. Every time recycling CICS regions would crash the IMS control region with U0113.
Then the automation would re-start the IMS back up. So we could live with that. :-)
Please advise, as an IMS Systems Programmer, what should be done with this situation? or just leave it alone? Thanks!

Do not tailgate othber ele's topics. Start your own. Topic locked.
The problem I have is that people can explain things quickly but I can only comprehend slowly.
