Question & Answer
Question
Why would my CICS region unexpectedly get message DFHDS0001 with abend 60D AKEB in module DFHDSTCB? I noticed that in the system trace (SYSTRACE), prior to the 60D abend there is an 0D7 abend and other exceptions coming out of a CA Detector for DB2 module.
This is the message I receive:
DFHDS0001 An abend (code 60D/AKEB) has occurred at offset X'FFFF' in module DFHDSTCB
Then eventually the CICS region comes down with an abend U1800.
In the CICS trace I can see:
*EXC* - DSTCB_RECOVERY - FUNCTION(TCB_REPLY)
Answer
CA Technologies provided PTFs RO82177 and RO82589 to resolve the abends.
Diagnosis showed that this error is happening because there is an EUT Functional Recovery Routine (FRR) established at this point and there shouldn't be. CA Detector probably establishes one at the beginning of a DB2 call and then it tears down the FRR at the end of the call. In this case, the FFR did not get torn down because of a PGM 25 that happened.
To make sure this is your problem, you will need a system dump of the CICS region at the time of the abend. You can enter IPCS command IP SYSTRACE to display the system trace. For this problem, the systrace looks like this:
0000 00XX 0094B988 PR ... 7 009C8F 2F2195F6
This PR is the completion of a call to DB2
0005 00YY 00955588 *PGM 025 00000000_2548FBC6 00040025 00000000
07049001 80000000 000000XX
This *PGM 025 is the first sign of trouble

ASID XX is CICS.

This is the fallout and you see the 60D abends eventually coming out.
