Hi,

I have a CICS that had just crashed after one transaction abended S0C4.
Basically, this CICS has not been refreshed for about 3 months and the transaction that abended is quite common. In fact, during this 3 months, many other types of abends had occurred on various types of transactions.

The S0C4 abend above had never crashed the CICS before, yet it is the last abend that caused this CICS to crash.

So, my question is is it possible that due to the cumulative abends over the past 3 months caused the CICS to crash?

If the CICS is refreshed daily, can this be avoided?


Thanks.

Hello,

is is it possible that due to the cumulative abends over the past 3 months caused the CICS to crash

This is not likely. . . Actually, newer releases of CICS regions crash only seldomly.

If the CICS is refreshed daily, can this be avoided?

Probably not if the crash is caused by some addressing fiasco. . . Many systems re-cycle all of the cics regions nightly to provide a "clean" starting point for the users each day. Many still have a "batch window" that processes batch jobs while the onlines are down.
