IC64827: THE GETENUMERATION() METHOD FOR QUEUEBROWSER RETURNS A SUBSET OF MESSAGES NOT PREVIOUSLY BROWSED. WMQ V6 RETURNS ALL MESSAGES.

WebSphere MQ V7.0.1 for i5/OS Fix Pack 7.0.1.3
WebSphere MQ V7.0 Fix Pack 7.0.1.3

APAR status

• Closed as program error.

Error description

• In WebSphere MQ v7.x, a QueueBrowser.getEnumeration() call
  returns only a subset of messages from the queue - those which
  have not been previously browsed. The same is true if more than
  one QueueBrowser is sharing the same session/destination. Each
  will get a set of messages that were not previously browsed.
  
  
  In WebSphere v6.x, the full set of messages is returned each
  time the getEnumeration() called.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects WebSphere MQ v7.x classes for Java Message
  Service (JMS) applications that create multiple QueueBrowser
  objects for the same session.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows) +Java
  ****************************************************************
  PROBLEM SUMMARY:
  When multiple QueueBrower objects are created for a single
  session, all the queue browser objects share the same queue
  handle. When the browsing, the queue handle advances only
  further instead of resetting to the top of the queue. Hence,
  when the getEnumeration() call is invoked, the browser will get
  the next available messages in the queue but not the
  messages from the top of the queue.
  

Problem conclusion

• The WebSphere MQ client has been updated to ensure each
  enumeration created from a QueueBrowser starts from the top of
  the queue.
