IC76544: WEBSPHERE MQ V7 JMS NON-DURABLE SUBSCRIBER IS ONLY ABLE TO RECEIVE ONE MESSAGE.

WebSphere MQ v7.0.1.7 Hypervisor for AIX
WebSphere MQ V7.0 Fix Pack 7.0.1.7
WebSphere MQ V7.0.1 for i5/OS Fix Pack 7.0.1.7

APAR status

• Closed as program error.

Error description

• A WebSphere MQ V7.0.1.5 JMS application that is using an
  asynchronous message listener on an auto-acknowledged session
  only processes one message. The message listener receives the
  first message published on its topic, but does not receive any
  subsequent messages.
  
  This problem only occurs on WebSphere MQ V7.0.1.4, V7.0.1.5 and
  V7.0.1.6, and not on V7.0.1.3.
  
  Also, only stand-alone JMS applications are affected.
  Applications running within an application server, such as
  WebSphere Application Server, that take out non-durable
  subscriptions receive messages as expected.
  

Local fix

• Make the session transacted, or client-acknowledged (or change
  the ConnectionFactory to say SyncpointAllGets = true).
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of:
  
  - The WebSphere MQ V7 classes for JMS
  
  that have applications which connect to a WebSphere MQ V7 queue
  manager and take out non-durable subscriptions on a topic.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows) +Java
  ****************************************************************
  PROBLEM SUMMARY:
  The WebSphere MQ V7.0.1.4 classes for JMS included some
  internal changes that affected the mechanism that the classes
  for JMS used to request messages from a WebSphere MQ V7 queue
  manager.
  
  A side effect of these changes was that applications which took
  out a non-durable subscription would only ever request one
  message from a queue manager. After this message had been
  delivered to the application for processing, the classes for
  JMS would wait for the queue manager to send additional
  messages automatically, without requesting any more to be sent.
  

Problem conclusion

• The WebSphere MQ V7 classes for JMS have been updated so that
  they request additional messages to be sent by the queue
  manager after the first message has been delivered to an
  application that has taken out a non-durable subscription.
