Subject Messages not forwarded to broker in duplex mode
Date Thu, 24 Jul 2008 20:24:54 GMT

This is my topology:
* Broker A is outside the LAN and has no network connectors.
* Brokers B and C are running on 2 different machines inside the LAN and
have duplex set to TRUE.
* Client sends a message to queue1 on brokerA and sends another message to
queue2 on brokerA.
* Broker A receives both the messages instantaneously.

Question #1: Brokers B and C do not appear to have the message. When I
browse the queue, I do not see any messages. However, after I browse the
queues on broker A using the activemq-admin command, the messages
immediately appear on both the brokers (B and C). How can this be explained?

* I send another message to broker A, first to queue1 and then to queue2.
* These messages do not appear on brokers B and C unless and until I bounce
both the brokers.

Question #2: Why is this the case, and how can I fix it such that the
messages show up instantaneously in the queues on brokers B and C?
