APAR status

• Closed as program error.

Error description

• When using mixed Put Message Options (PMO) such as PMO = 2
  (MQPMO_SYNCPOINT), PMO = 4 (PMO_NO_SYNCPOINT) or PMO = 2050
  (MQPMO_SET_ALL_CONTEXT + MQPMO_SYNCPOINT) for MQPUTs, DataPower
  might use a cached queue handle that is not appropriate for a
  MQOPEN call with PMO = 1024 (MQPMO_SET_ALL_CONTEXT) under load.
  This causes MQ error code of 2095 (MQRC_NOT_OPEN_FOR_SET_ALL).
  

Local fix

• Configure DataPower MQ URLs to use PMO with the higher value
  for all MQPUTs associated with the application.
  

Problem summary

• A customer who uses multiple DPMQ URL-Openers with the
  same queue is likely to see this problem.
  
  The wrong MQ open handler was reused while DPMQ URL-Openers with
  different PMO/GMO were requested sequentially.
  

Problem conclusion

• Fix is available in 5.0.0.12, 6.0.0.4 and 6.0.1.1.
