DFHXS0001 0C4 AKEA in DFHXSPW after CA ACF2 PTFs

Question & Answer


Question

After putting on CA ACF2 PTFs from CA Technologies, why did I start receiving DFHXS0001 abend 0C4 in my CICS Transaction Server for z/OS (CICS TS) region? Here is the symptom string:

MESSAGE: DFHXS0001 An abend (code 0C4/AKEA) has occurred at offset X'FFFF' in module DFHXSPW.
SYMPTOMS: PIDS/5655Y0400 LVLS/700 MS/DFHXS0001 RIDS/DFHXSPW PTFS/UI42764 AB/S00C4 AB/UAKEA ADRS/0000FFFF

Answer

When I use IPCS command VERBX DFHPDxxx 'TR=1' (where "xxx" is the release of CICS like "710" for CICS TS 5.4) to display the CICS trace in the system dump of the abend 0C4, the trace shows the task received an INQUIRE_PASSWORD_DATA exception after the task was ended by RET-90A4E176 which was out of CA Technologies module CAS9C70+B176:

IPCS command VERBX DFHPDxxx 'KE=1' shows the following information in the KE Error Table Summary:

Backing up from the PSW using option 1 from the IPCS primary option menu to Browse the dump, I found the failing instruction "BF3F2000" in DFHXSSB (UI42764) at offset x'964':
ICM R3,X'F',X'0'(R2)
R2:00000000_FFA8F07F is bad causing the abend0C4.

If you want to verify that the PSW in your dump is the same and need help, you might want to take a look at Locating the PSW for a program check in a CICS TS system dump.

Please contact CA Technologies for the fix ST04534 if your symptoms look the same.
