APAR status

• Closed as program error.

Error description

• If an invalid series of calls (mixture of XA and MQ) is being
  issued, i.e. a XA_OPEN followed by an MQGET, the MQGET call
  fails with MQRC=2195 (MQRC_UNEXPECTED_ERROR) and the CSQSERVICE1
  specific abend 5C6-0094002E is being produced.

  ****************************************************************
  The problem is seen when using an XA client to issue an MQGET,
  MQPUT or MQPUT1 in syncpoint directly after an XAOPEN without
  issuing an XASTART via a SVRCONN channel with CSQSERVICE1
  enabled.
  
  This XA flow will incorrectly return the MQRC 2195
  (MQRC_UNEXPECTED_ERROR) and produce the abend 5C6-0094002E.
  

Problem conclusion

• The MQRC that is being issued when an MQGET, MQPUT or MQPUT1 is
  called in syncpoint after a XAOPEN has been corrected so that
  now MQRC 2072 (MQRC_SYNCPOINT_NOT_AVAILABLE) will be returned
  instead and the abend no longer produced.
