HI All,

One of our CICS transcaction has failed with dead lock, On analysis we could see that one of the batch program which run every 5 mins is causing the transcation to end in Deadlock

Both the transcaction and batch is using the same db2table to update.

Code:
THREAD-INFO=XXXX:*:*:*
IS DEADLOCKED WITH PLAN=PPPPPXXX WITH
CORRELATION-ID=PPPPPPPP
CONNECTION-ID=BATCH
Please suggest how we can avoid this deadlock.

Thanks

Hello,

Is this resolved?

The problem is a design issue. One of the processes locks resource A and then tries to lock resource B. At the same time, another process locks resource B and then tries to lock resource A. It may not be trivial to change/correct, but the transactions should lock resources in the same order.
