PM61351: FAULT ANALYZER IS NOT ABLE TO DETECT DUPLICATE CICS TRANSACTION ABENDS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Fault Analyzer is not able to detect duplicate CICS transaction
  abends. Looking at a FA dump we were able to determine that
  for AZI6 abends the TACB contains the ABNDREGH regs at offset
  58 and ABNDGPRS at offset 98 for CICS TS 4.1.
  
  When looking at a CICS TS 4.1 dump we can see that the TACB
  ADDRESS at offset x'58' we have the ABNDREGH regs and the
  ABNDGPRS regs at offset x'98'.
  
  The CICS Data Areas for DFHTACBS show the following
  offsets:(58) CHARACTER 64 ABNDGPRS GPREGISTERS 0 - 15 ON ENTRY
  TO ABEND (98) CHARACTER 64 ABNDREGH GPREGISTERS 0 - 15 HIGH
  WRDS ON ENTRY ABEND
  
  The code in DFHZAND has an incorrect offset value into the stack
  and the result is that the low word of one register and the
  high word of the next register, which in turn results in the
  contents of ABNDGPRS and ABNDREGH are incorrect.

  *                      once, Fault Analyzer is not able to     *
  *                      detect duplicate AZI6 abends.           *

  ****************************************************************
  A CICS region is communicating with another CICS region.
  AZI6 abend occurs due to a remote abend. DFHZAND creates the
  TACB for the AZI6 but has invalid offsets to 64 bit registers
  which results in the TACB containing invalid register
  information. This results in Fault Analyzer being unable to
  detect duplicate abends.
  

Problem conclusion

• DFHZAND is amended so that the correct 64 bit registers are
  passed to DFHABAB.
