Question & Answer
Question
Why am I receiving message "DFHAP0001 An abend (code 0C4/AKEA) has occurred at offset X'0674' in module DFHERM" during an EMERGENCY or WARM start of CICS Transaction Sever for z/OS (CICS TS)? The failure does not occur during INITIAL and COLD starts. I am running with CA Technologies CA Event Notification Facility.
I looked at the CICS TS V5.3 fix list, and I don't see existing maintenance that hits this module.
Answer
Looking at the code in DFHERM +x'0674', CICS is expecting Register 4 (R4) to contain a pointer to a valid address. However,if you look at a system dump of the abend, you will see that R4 points into a TIE in the midst of an area holding a very recent timestamp:
|.Y>TIE-- CAS ............"...|
|.............."4..........MYNET.|
|CICSXXXXI........... CAS .06/|
|07/16.03:01:n1..................|
^^^^
See Locating the PSW and registers for a program check in a CICS TS system dump if you need help finding the registers in your dump.
If your problem looks the same, applying the CA Common Services 14.1 PTF RO75580 should resolve the abend 0C4 in DFHERM.
Contact CA Technologies if you need additional assistance.
