TIBCO ActiveMatrix BusinessWorks™ Plug-in for WebSphere MQ 8.5.1 Hotfix 7 is released for all platforms. Please refer to the product readme file for details regarding the supported platforms.
Listed below is a summary of updates included in this Hotfix. Please refer to the Hotfix Readme for additional details and installation instructions.

======================================================================
Closed Issues in 8.5.1_HF-007

    BWMQ-865   Activities leak memory while checking for a zOS server 
        because the PCFAgent for client version 9.x does not cleanup on
        disconnect.  This results in a consumption of memory proportional
        to the number of activities executed and the number of listener 
        polling calls made. 

Closed Issues in 8.5.1_hotfix06

    BWMQ-839   Put/Get version of request reply pattern fails if the 
        dynamic reply queue is not sharable.  This was introduced in
        hotfix 5 when optimizing the RequestReply activity and has been
        reverted in hotfix 6.
            
    BWMQ-836   Repackaged hotfix 5 as a full installer with attendant
        BWCE runtime archive.  The only functional difference from HF5
        is that the test button for MQ server version 9.1 will work.

Closed Issues in 8.5.1_hotfix05

    BWMQ-827   Use of PCFAgents sometimes leave dynamic temporary queues 
        allocated on the server.

    BWMQ-826   RequestReply activity with dynamic reply queue getting an
        NPE on the response queue.

    BWMQ-824   RequestReply activity fails when used in a loop.
            
    BWMQ-818   Sometimes the get or listen activities will get an error 
        when running on zOS after changing the get options due to non-indexed
        queues.

    BWMQ-816   Delay the startup of listeners so that queue managers can allocate
        multiple conversations per physical connection.  To effect the behavior
        add this java property to the tra:
        com.tibco.bw.palette.mq.runtime.MqReceiver=5
        which will delay connections 2-n by 5 seconds so that all connections
        can participate in the shared conversation.

    BWMQ-815  Test button and runtime not working on server version 9.1.
        The queue manager inquire method crashes the server connection 
        channel on MQ server version 9.1.  This results in the test button
        and the runtime not being able to connect to the queue manager.
        Note that this hotfix addresses only the runtime issue.  The test 
        button will not work on server 9.1 but queue choosers and the runtime
        will work.
        
    BWMQ-811  If Listener/Subscriber server connection is terminated forcibly
        the listener will report errors too fast for the engine to handle, 
        resulting in excessive resource consumption and eventually out of memory 
        conditions.
    
    BWMQ-807  Topic Subscriber does not work on zOS queue manager versions 9.x

    BWMQ-793  Disable Listener/Subscriber error events when the server or server
        connection channel is unavailable or while switching to fault tolerant
        partner.
        To effect this behavior set the following parameter in the application.tra:
        com.tibco.bw.palette.mq.runtime.DisableEventsourceFaultEvents=true
        
Closed Issues in 8.5.1_hotfix04

    BWMQ-798 Connections are not released after app is stopped.  Connections
        are now closed correctly if the application is stopped while the 
        listener was blocked on an MQ get call.

Closed Issues in 8.5.1_hotfix03
       
    BWMQ-789 Customer has messages with embedded nulls that they want 
        "sanitized" via the same mechanism used in BWMQ-711
        Modified the plugin to replace embedded nulls with '.' chars
        when the special jvm parms from BWMQ-711 are set to true. 
        Also ensured that embedded nulls dot truncate messages regardless
        of the sanitization parms.    


Closed Issues in 8.5.1_hotfix01
       
    BWMQ-696  Listener Fails to reconnect with exceptions when connection lost.
               
    BWMQ-711  Incoming corrupt message cannot be mapped by engine
        Important usage notes:
        Two system environment parameters are now observed by the plugin:
            com.tibco.bw.palette.mq.runtime.sanitizeMqmdHeaderFields=true
            com.tibco.bw.palette.mq.runtime.sanitizeMessageText=true
        Set them to have invalid XML characters in either the MQMD header
        fields or the message body replaced with the '.' character.
