JBoss Messaging Slow Consumer Messages Clustering

Latest response

I have JBoss EAP 5.1.2 (incl. JBoss Messaging 1.4.8) with JMS clustering.

The consumers are slow (several minutes) with various execution time (1-30 minutes) so I enabled the message redistribution (ClusterPullConnectionFactoryName).

 

My ConnectionFactory attributes are:

<attribute name="SupportsFailover">true</attribute>
      <attribute name="SupportsLoadBalancing">true</attribute>  
      <attribute name="DisableRemotingChecks">true</attribute>
      <attribute name="PrefetchSize">1</attribute>
      <attribute name="SlowConsumers">true</attribute>
      <attribute name="SupportsFailover">true</attribute>
      <attribute name="SupportsLoadBalancing">true</attribute>  
      <attribute name="PrefetchSize">1</attribute>
      <attribute name="SlowConsumers">true</attribute>

 

Of course, the corresponding post office is clustered as well.

 

However, messages are not distributed equally in the cluster, some nodes are fully loaded, some of them are almost idle.

 

Please, do you have any hint how to (re)ditribute messages equally in the cluster?

Thanks

OJ
