Hi,

One job abended and i was called for help.
Job abended with U0064,I did a JCL scan and got this
Code:
 
***ERROR  - DSS4420E - GENERATION DATA GROUP DOES NOT EXIST


Clearly shows what is the issue.
But this job ran fine yesterday, and this is Production , I was just wondering possible causes.

I do not think this GDG would have been removed ,this is Production and we have strong processes in place .this should not have happened.

Any ideas what could be the reason. I have seen this error first time.

Why not just look under TSO ISPF option 3.4 and know for sure rather than thinking? Without facts, such as finding out for sure about the GDG, we're not going to be able to do anything more than guessing and you can do that just as well as we can.

And, by the way, I've seen a number of cases where someone thought they were working with test data sets and made changes to production by mistake so it is entirely possible that the GDG was deleted. No, it should not have happened -- but that doesn't say it did not happen. In at least one case the person used their emergency id so they had full access to the production data sets even though there was no reason for that use.

Hello,

Either the dataset does not have proper security defined or someone with permission erroneously deleted the dataset.

I suspect this job is the "victim" rather than the "culprit". Some other job or some person most likely deleted the gdg base.

SMF records, in the 60's range, can not recall the exact record type needed, to find out who and when for deleting the dataset.
