Abend 0C4 in DFHPGCH
You are missing fix TC8960M from CA Technologies for CA ACF2.
Diagnosing the problem
A review of the CICS dump shows an ABENDS0C4 in DFHPGCH. LOGDATA shows the 0C4 in CAS9578E - Product = J161.
CA ACF2 is using the parameter list from the CICS TRANSFORMER 2 call (expecting it to be fully populated) in order to determine the presence of a channel and channel token XTSCHANT at offset x'88'. CICS is only populating the parameter list as needed, so some non-zero fields should not have been relied upon by CA ACF2.
Resolving the problem
CA Technologies has a test fix named TC8960M for both CA ACF2 R12 and R14. The ACF2 problem number is 8960. Contact CA Technologies if you need further assistance.
