Subject [jira] Commented: (AMQ-2324) Forwarded message cannot be distributed to the original broker
Date Fri, 05 Feb 2010 19:22:32 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-2324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=57406#action_57406
] 

Sam Perman commented on AMQ-2324:
---------------------------------

Just wanted to add some more context. This means the Spring Integration {{JmsOutboundGateway.sendAndReceive}}
will fail in a multi-broker environment as well.

Should this be considered a bug or is it really an Improvement? (In other words, is there
a workaround?)

> I have a simple cause which can cause dispatch problem:
> 1. setup a network of broker1, broker2, bridged by multicast discovery
> 2. make a producer send 5 msg to queueA to broker2
> 3. make a consumer to consume from broker1 queueA ( make it slow, so it only consumer
1 msg) but make sure all 5 msg from broker2 are forwared to broker1
> 4. stop the consumer to broke1, restart it to consume from broker2 queueA
> 5. the 4 msgs originally published to broker2 and forwarded to broker1 and has not yet
been consumed will stuck on broker1 and will not forwarded to broker2 for the consumer to
consume. 
> Here is an solution: it checks forwarded to broker( eg, broker1) to see whether it has
any active consumer, it will be able forward the message back to the original broker when
there is no active consumer on the forwarded to broker.
