PI42711: MQ Z/OS V7.1: A TRANSACTION EXPIRES IN IMS DFS3688I IS RETURNED WHEN EXPIRY VALUE AND NO REPORT OPTION ARE SET ON INPUT MESSAGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Using MQ v7.1 and IMS v13 customer was testing MQ/IMS bridge
  transactions expiration in IMS.
  If the transaction expires in IMS they do not expect a reply to
  be sent unless a report has been requested.
  They found that:
  If they request an expiry report then they correctly get
  the reply message with MQMD-FEEDBACK set to 258, and no
  DFS3688I message.
  However if they specify no MQMD-REPORT option on the input
  message, they still receive a reply from IMS which is a
  DFS3688I message.
  
  If a message with the same expiry and report setting is expired
  by OTMA rather than IMS, then
  a message is not returned to the application so there is an
  inconsistency here.

  ****************************************************************
  When a message is put to an IMS bridge queue with an Expiry
  value in the MQMD, and no expiration reports are requested in
  the MQMD Report field (MQRO_EXPIRATION*), no reply should be
  returned to the application if the transaction expires, however
  CSQ2QCP1 does not account for this and incorrectly puts the
  DFS3688I (transaction expired) response to the reply queue.
  

Problem conclusion

• CSQ2QCP1 is changed to no longer put the DFS3688I response to
  the reply queue if the request message specified an expiry
  interval in the MQMD and no expiration report options. The
  response will still be put if the request message specified
  unlimited expiry (MQEI_UNLIMITED) and the transaction expired
  for some other reason (for example, if the transaction is
  defined to IMS with the EXPRTIME parameter).
