Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A JMS client fails with RC2033 ( 2033 ) MQRC_NO_MSG_AVAILABLE
  if more than one selector is used with JMSXGroupID
  (in this case the failing MQGET also specifies JMSXGroupSeq=2).
   The problem ocurs as CSQMATCH is not being passed the MDE
  details from CSQEMGEF.
  
   The JMS application log throughs the following exception:
  
  JMSServiceException - An error occurred during MQ call:
  "Error browsing the message
  ID:e7c7c1c4c2d6d540c2f0f2f4f0f0f0f0f3f3f5f940404040 from

  * PROBLEM DESCRIPTION: An MQGET with a selector specifying     *
  *                      GroupId fails with MQRC 2033 when the   *
  *                      target message is held on a SMDS        *
  *                      (shared message data sets).             *

  * RECOMMENDATION:                                              *
  ****************************************************************
  This problem can occur when CSQIPROP does not return the address
  of the MQMDE when a message is stored on SMDS.  This causes the
  message to not be returned when using JMS selectors specifying a
  GroupId - as this selector needs to be matched against the
  corresponding fields held in the MQMDE of the message.
  

Problem conclusion

• The code has been changed to ensure the MQMDE is returned by
  CSQIPROP for messages stored on SMDS when a selector specifies
  GroupId.
