In your question you're asking about diagnosing by using the offset. However, in this case, that's probably not going to help. The offsets shown will be in the IBM-provided Db2 (DSN...) or CICS (DFH...) libraries, and it's going to be very difficult for you to use those offsets without the listings for those compiled libraries.

Instead, you should approach debugging via the abend code: AD2R.

If you search for that abend code, you'll find its information page:

AD2R

Explanation

The CICS-DB2 attached TCB connection that processes the DB2 request for this transaction has abended. An exception trace, AP 319D, is written containing the MVS abend code; MVS reason code; and the relevant CICS-DB2 control blocks that are used by the CICS task and by the CICS-DB2 TCB connection. One of the control blocks returned is the CSUB control block. This control block contains data from the MVS SDWA at the time of the abend, for example, the CSB_SDWA_REGS (regs 0-15) and the CSB_SDWA_PSW fields. The CSB_SDWA_REGS is the 16 words following the SDWA eye catcher. The CSB_SDWA_PSW field is the two words following the CSB_SDWA_REGS field.

The TCB connection is terminated if a CICS transaction is forcepurged from CICS when the thread is still active in DB2.

System action

The task is abnormally terminated with a CICS transaction dump.

User response

Examine the trace in the CICS transaction dump to determine why the CICS-DB2 thread TCB abended.

Module

DFHD2EX1

So this instructs you to find out more by investigating the transaction dump that was produced.

Prior to doing that, though, I would suggest you also scan the CICS logs immediately prior to the point where the transaction dump was issued, to determine if there are useful diagnostics printed.
