Message lost in network of brokers (ActiveMQ 4.0.2)
I'm loosing messages within a network of broker using ActiveMQ 4.0.2. This
is my testcase:
I'm starting two brokers (A and B). I register a durable subscriber on
broker B for topic a.>
When I send a message to top a.b on broker A, I receive the message on
Broker B.
Next, I stop broker B. A new message is sent to broker A on topic a.b. I
start Broker B again. The durable subscriber register on broker B receives
the message. Nothing went wrong up to now.
I stop broker B again. I send a message to topic a.b on broker A. I stop
the sender and the receiver. (the message should live on broker A) Next, I
start broker B. Broker B should get the message because a durable subscribe
for the topic was created. I stop broker A and starts the receiver (which
is connects to broker B). The message does not arrive. (I get an exception
say that the subscription does not exist). I restart the receiver and I get
no message.
When I start broker A again, I still get no message.

Hi,
i overlooked the durable subscriber part.. it should have worked, but i
also encountered the same problem...
I will be raising an issue for this, so it will be fixed sooner.

Hi,
And you can also try a MasterSlave configuration for your brokers as another
solution, if your not using it already.. Hope that helps..

Re: Message lost in network of brokers (ActiveMQ 4.0.2)

Hi,
Have you set the ForwardingBridge for the 2 brokers? If not, the problem is
because it uses the default bridge, which is the DemandForwardingBridge.
AFAIK, you do not receive message because broker A only forwards the message
from topic a.b upon demand, which means that broker A only forwards the
message from topic a.b to broker B when a consumer consumes the message. So
when brokerA is down, you get an exception that it does not exist because
the message was actually on broker A. The solution to your problem, if you
have not already done so, was to create a ForwardingBridge for the two
brokers.
Regards,
Marlon
