Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Ø
  The failing instruction for the ABENDS0C4 PIC10 is 4430 C1E6.
  The problem is that the PSW is in KEY7, but Reg12, which points
  to CSQMNCPY+0 is in KEY0.
  
  The ABEND0C4 occurs in CSQMNCPY when MQOO_RESOLVE_LOCAL_Q/TOPIC
  is specified when opening a topic object. CSQMTOPN locates the
  address of the name of the topic object, which is in 64-bit
  storage, but it only passes a 31-bit address (i.e. low word) to
  CSQMNCPY for copying the name of the object back to the MQOD.
  
  Additional Symptom(s) Search Keyword(s):
  ABEND5C6 5C6 00E7014F in CSQXADPM may be a secondary symptom
  after the ABEND0C4.

  ****************************************************************
  When CSQMTOPN is processing MQOPEN with MQOO_RESOLVE_LOCAL_Q
  option, it passes half of the 64bit address of the source field
  with the name of the administrative topic object to copy to
  MQOD.ResolvedQName target field by routine CSQMNCPY resulting in
  the 0C4 abend.
  

Problem conclusion

• Unnecessary code that calls CSQMNCPY has been removed from
  CSQMTOPN and CSQMOPNI has been changed to return the correct
  value in MQOD.ResolvedQName.
