Hello all,
I built active/active cluster with two brokers for my first tests. I can
see in the log that the two brokers built a cluster. After startup
everything looks fine.
I configured one queue and sent a message using AMQP 1.0 to broker1 and
tried to read it from broker2.
But broker2 throws an exception and the message is not sent to the client:
09:34:53,146 ERROR [org.apache.activemq.artemis.core.server] AMQ224016:

The queue is not created on the fly but configured in the brokers, both
brokers have this config:
<queues>
<queue name="awe.test.queue">
<address>awe.test.queue</address>
<durable>true</durable>
</queue>
</queues>
The cluster configuration is pretty much copied from the examples:
<!-- Clustering configuration -->
<broadcast-groups>
<broadcast-group name="my-broadcast-group">
<group-address>${udp-address:231.7.7.7}</group-address>
<group-port>9876</group-port>

<connector-ref>netty-connector</connector-ref>
</broadcast-group>
</broadcast-groups>
<discovery-groups>
<discovery-group name="my-discovery-group">
<group-address>${udp-address:231.7.7.7}</group-address>

</discovery-group>
</discovery-groups>

I am using qpid-send and qpid-receive as test clients. So when the client
sends it is done like:
qpid-send -b localhost:9800 -a awe.test.queue
'--connection-option={protocol:amqp1.0}' --content-string 'test message Do
7. Dez 09:31:51 CET 2017' --durable=yes
And there is a client which reads using:
qpid-receive -b localhost:9802 -a awe.test.queue
'--connection-option={protocol:amqp1.0}' -t --timeout 500
I think I misconfigured something but I can not imagine what it could be.
Btw. what protocol is used between the two brokers?
I activated only the protocols AMQP and CORE.
Any ideas?
Kind Regards,
Andreas
