Error description
A system was migrated from WebSphere MQ V6 to V7.1, including the WebSphere MQ Explorer component. When the user logs on to the Windows server and starts the WebSphere MQ Explorer, the queue manager is visible in the Navigator. However when the WebSphere MQ Explorer is stopped and restarted, the queue manager is no longer visible.

Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of the WebSphere MQ Explorer V7.0.1 and V7.1. Platforms affected: Linux (x86),Linux (x86-64),Windows **************************************************************** PROBLEM SUMMARY: A thread synchronisation issue surrounding an internal data structure used within the WebSphere MQ Explorer permitted concurrent thread access to the data structure. The consequence of this was that the list of queue managers to be displayed within the WebSphere MQ Explorer may have ended up as an empty list, even when there was previously queue managers displayed.
Problem conclusion
Thread synchronisation was enhanced around the access of the internal data structure, which prevents further concurrent access. In addition, additional trace points were also added to indicate the state of the lock acquisition to assist with future diagnostics of problems encountered in this area. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.10 -------- -------------------- Windows 7.0.1.10 Linux (x86) 7.0.1.10 Linux (x86-64) 7.0.1.10 v7.1 Platform Fix Pack 7.1.0.2 -------- -------------------- Windows 7.1.0.2 Linux (x86) 7.1.0.2 Linux (x86-64) 7.1.0.2 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
