Distributed queue - uneven load-balancing

Question

I've read relevant threads, JMS : loadbalancing of messages is not happening uniformly between all the is close but no help.
I have 6 managed nodes in a cluster, nodes 1-3 on box A, nodes 4-6 on box B. I have a distributed queue + connection factory with server affinity disabled and load balancing enabled. Both the queue and connection factory are deployed (targeted) to the entire cluster. The sender on node 1 pushed 100k messages into the queue and 33k ended up evenly distributed (right down to a message!) across physical queues on 3 nodes on box A. Queues on nodes 4-6 received no messages. During the test all physical queues were alive and well, producers and consumers (MDBs) were alive and well, all nodes were up and so on. In the cluster config I said I've got 6 nodes (Number Of Servers In Cluster Address field). Please tell me something is wrong with my config and this is not a bug that I have to bring up with Support..
I am on 10.3.3 on Linux 64-bit wit JRockit 1.6

Hi,
No, this is not the correct way the JNDI tree supposed to look for distributed queue in a single cluster with two hosts. This means that either your configuration is wrong or both the hosts are not connected to each other properly.
In your scenario this should be your architecture
Box-A
=====
AS
MS-1, MS-2, MS-3 under Cluster
JMSServer-1 => MS-1
JMSServer-2 => MS-2
JMSServer-3 => MS-3
JMS_Module => Cluster
SubDeployment_UDQ => JMSServer-1, JMSServer-2, JMSServer-3
ConnFacty => Cluster
UDQ => SubDeployment_UDQ
Box-B
======
MS-4, MS-5, MS-6 under Cluster
JMSServer-4 => MS-4
JMSServer-5 => MS-5
JMSServer-6 => MS-6
JMS_Module => Cluster
SubDeployment_UDQ => JMSServer-4, JMSServer-5, JMSServer-6
ConnFacty => Cluster
UDQ => SubDeployment_UDQ
Where: *=>* means targeted to
In Box-A and Box-B the Cluster, SubDeployment_UDQ, ConnFacty and UDQ are the same NOT different.
Once this is done then you should be able to see UDQ and ConnFacty on all the servers JNDI tree then its the right configuration and now when you send messages on UDQ using the ConnFacty with "affinity disabled" you will see the messages getting distributed properly on all the 6 servers.
Hope this helps you.
