Subject [jira] Commented: (AMQ-2324) Forwarded message cannot be distributed to the original broker
Date Fri, 05 Feb 2010 19:32:34 GMT


Bruce Snyder commented on AMQ-2324:

When this functionality was originally added to ActiveMQ, it was a deliberate design change.
The eventual goal of this issue is to make it more easily configurable as currently it's only
baked into the code.

> 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
> 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.
