    message stuck in clustered queue

    Tan Pauline Newbie

      Hi, I'm using JBoss AS 5.1 with messaging 1.4.3 to do clustering. My setup is 2 JBoss nodes (A & B) with 2 standalone applications pointing to the nodes separately. The problem is sometimes the nodes will have 1 consumer each, and the messages can be received correctly, but sometimes both consumers will camp at node A or B only, and messages sent to the other node will not be consumed. I ran the distributed-queue example and it works fine though.

       

      I have configured my setup as below:

       

      connection-factories-service.xml

         <mbean code="org.jboss.jms.server.connectionfactory.ConnectionFactory"

            name="jboss.messaging.connectionfactory:service=ClusteredConnectionFactory"

            xmbean-dd="xmdesc/ConnectionFactory-xmbean.xml">


            <attribute name="SupportsFailover">true</attribute>

            <attribute name="SupportsLoadBalancing">true</attribute>     

            <attribute name="DisableRemotingChecks">true</attribute>     

            <attribute name="LoadBalancingFactory">org.jboss.jms.client.plugin.RoundRobinLoadBalancingFactory</attribute>    

       

      messaging-service.xml

            <attribute name="ClusterPullConnectionFactoryName">jboss.messaging.connectionfactory:service=ClusterPullConnectionFactory</attribute>

       

      mysql-persistence-service.xml

            <attribute name="Clustered">true</attribute>

           <attribute name="FailoverOnNodeLeave">true</attribute>  

       

      my-destinations-service.xml

              <attribute name="Clustered">true</attribute>

       

      Another problem is when the 2 consumers are at node A and the message is stuck at node B, after shutting down node B (either through ctrl-c or closing the window), the message does not failover to node A, even though on the console it says

       

      [ INFO][org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.info():296] JBoss Messaging is failing over for failed node 1. If there are many messages to reload this may take some time...

      [ INFO][org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.info():296] JBoss Messaging failover completed

       

      Appreciate if anyone can help to answer my question. Thanks.
