PK51581: EIP ENTRY RET FIELD HAS INCORRECT OUTPUT UNDER L8 OR L9 TCB AND USING THE OPENAPI INTERFACE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The EIP ENTRY RET field has incorrect output under L8 or L9 TCB.
  Assume a program has been defined with CONCURRENCY(THREADSAFE)
  and API(OPENAPI), and CICS has STGPROT=YES.
  The program is executed with auxilliary trace on. When the trace
  is formatted, the "AP00E1 EIP ENTRY" trace entries for the L9
  TCB show RET(04FF0000) for all such trace entries. The "AP00E1
  EIP EXIT" trace entries have the correct RET() value for each
  trace entry.
  If the same program euns under the QR TCB the EIP ENTRY/EXIT
  trace entries have the same value, which is the return address
  to the application making the EXEC CICS request.

  ****************************************************************
  In the reported problem, a transaction running on an open TCB
  was being traced.  A SHORT or FULL trace of the transaction
  showed that for an AP 00E1 EIP ENTRY trace entry, the RET
  value contained '04FF0000'.  DFHEIP relied on a R14 value
  prior to making the trace entry.  However, a codepath existed
  that reloaded R14 with the erroneous value and it was this
  that was traced out in the RET field.
  

Problem conclusion

• DFHEIP has been modified, R14 is now reloaded from RSABAR which
  contains the correct RET address.
