DFHLD0001 0C4 AKEX at 73CE in DFHLDDMI during CICS initialization

Question & Answer


Question

Why do I get DFHLD0001 abend 0C4 AKEX at offset X'73CE' in DFHLDDMI when I try to start my CICS region? CICS will not initialize. It fails with the following error:

DFHLD0001 AN ABEND (CODE 0C4/AKEX) HAS OCCURRED AT OFFSET X'73CE' IN MODULE DFHLDDMI.

DFHME0116 (MODULE:DFHMEME) CICS SYMPTOM STRING FOR MESSAGE DFHLD0001 IS PIDS/5655Y0400 LVLS/680 MS/DFHLD0001 RIDS/DFHLDDMI PTFS/HCI7000 AB/S00C4 AB/UAKEX ADRS/000073CE

No changes were made to the region.

Answer

The DFHME0116 message that follows message DFHLD0001 shows that the code in the CICS region is mismatched:

  • The LVLS (levels) show the region is at CICS release "680". This is equivalent to HCI6800 for CICS Transaction Server for z/OS V5.1.

  • The PTFS (PTF level) for module DFHLDDMI show it is at "HCI7000". This is equivalent to CICS release 700 for CICS Transaction Server for z/OS V5.3.

Other CICS regions were updated to the new CICS TS V5.3 code and the new code was put into the LPA. But, the older CICS TS V5.1 regions still had LPA=YES in the system initialization table (SIT) OVERRIDES, as shown in the CICS message log:

 DFHPA1100  OVERRIDE PARAMETERS FROM JCL EXEC STATEMENT: START=AUTO,SYSIN
 
 DFHPA1102  OVERRIDE PARAMETERS FROM SYSIN:
 
 DFHPA1927  LPA=YES,

After changing the SIT overrides to LPA=NO, the abend 0C4 in DFHLDDMI no longer occurred.
