PH37486: HANDLE ABEND RESET PROCESS GETS ABENDU4082 RC03 AFTER 1ST TIME

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A transaction in a routing region issues a START to a target
  region and also uses HANDLE ABEND RESET, so that if the mirror
  transaction in the target region is no longer present, eg
  receiving abend with AZI2 or AZI4, it then retries the START.
  This process works the first time, but any further fault results
  in Language Environment abendu4082 reason 00000003 ( rc03 ).
  In CICS TS 5.4, the process worked multiple times. The process
  no longer works in CICS TS 5.6.
                                                                 .

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: EXEC CICS START suffers LE abend 4082.  *
  ****************************************************************
  A CICS program running under Language Environment (LE)
  issues EXEC CICS HANDLE ABEND to recover from anticipated abend
  situations.
  The program then issues an EXEC CICS START command which
  experiences an anticipated abend.
  CICS enters HANDLE ABEND processing.
  CICS calls LE to perform Rununit_End_Invocation - passing
  incorrect application registers because DFHEIIC has previously
  issued a DFHRMCAL context switch call which has driven DFHEIP
  recursively.
  LE issues ABEND 4082.
  The CICS transaction does not recover from the abend situation
  and terminates.

Problem conclusion

• CICS Interval Control processing (EXEC CICS START)
  has been modified to preserve application registers.
