PH67106: LE ABEND CODE 4088 RC=63 AFTER USER APPLICATION FAILS WITH EITHER AD3T OR AD3F TRANSACTION ABEND CODES.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When CICS calls to LE for Rununit_End_Invocation for the running
  program it expects to receive parameters which includes a
  pointer to the registers from the Cobol application program's
  last EXEC CICS call. DFHAPLI1 gets those registers from
  TCAREGPT. But for those tasks failing with AD3T or AD3F abends,
  those registers belong to DFHAPEX. They are no longer the
  registers from the Cobol application program's last EXEC CICS
  call. These DFHAPEX registers are not going to make sense to LE
  so it raises the abend 4088 RC=63.

  ****************************************************************
  * PROBLEM DESCRIPTION: Incorrect registers are passed to       *
  *                      Language Environment after CICS         *
  *                      processes an abend in Db2.              *
  ****************************************************************
  An LE-conforming subprogram is doing Db2 work where a problem
  causes CICS to start abend processing. On percolating
  the abend up the linkage stack, CICS is supposed to pass to LE
  the registers as they were at the time of the last EXEC CICS
  command. Instead, because of DFHEPC issuing a call to DFHAPEX
  for RMI_SWITCH_APPLICATION_ENV, CICS calls LE for
  rununit_end_invocation with the registers for DFHAPEX. LE issues
  abend 4088 while in rununit_end_invocation because it thinks
  that the application registers are bad.
  

Problem conclusion

• DFHEPC has been changed to preserve the application registers
  around the call to DFHAPEX.
