Multiple Clusters on the same network

[mandarbk]

I have multiple clusters on the same network (LAN).

Currently, I am facing an issue with HornetQ configuration,

ERROR (Thread-11 (HornetQ-client-global-threads-1319079009)) 2012-11-20 15:08:40,953 [org.hornetq.core.server.cluster.impl.ClusterConnectionImpl] HornetQLoggerFactory$HornetQLogDelegate Failed to handle message: java.lang.IllegalStateException: Cannot find binding for 5ea6ba12-ab4b-4a0a-bf18-c2e52e852573e8370d59-3323-11e2-a6c0-005056a1003a on ClusterConnectionImpl@198385039[nodeUUID=e8370d59-3323-11e2-a6c0-005056a1003a, connector=org-hornetq-core-remoting-impl-netty-NettyConnectorFactory?port=5445&host=0-0-0-0, address=jms, server=HornetQServerImpl::serverUUID=e8370d59-3323-11e2-a6c0-005056a1003a]

Is there any documentation that explains all the steps/problems we can encounter when we are trying to setup multiple clusters on the same network ?

[rhusar]

Not sure how HornetQ is handling this, but judging from AS7 clustering view point: did you specify different UDP groups (or ports) for the clusters?

[mandarbk]

I was able to resolve the problem, by making sure that every cluster has a unique value for [broadcast-group -- group-address] and [discovery-group -- group-address]

<broadcast-groups>

                <broadcast-group name="bg-config">

                    <local-bind-port>9877</local-bind-port>

                    <group-address>224.1.22.1</group-address>

                    <group-port>9876</group-port>

                    <broadcast-period>5000</broadcast-period>

                    <connector-ref>

                        netty

                    </connector-ref>

                </broadcast-group>

            </broadcast-groups>

            <discovery-groups>

                <discovery-group name="dg-config">

                    <group-address>224.1.22.1</group-address>

                    <group-port>9876</group-port>

                    <refresh-timeout>10000</refresh-timeout>

                </discovery-group>

            </discovery-groups>

            <cluster-connections>

                <cluster-connection name="config-cluster">

                    <address>jms</address>

                    <connector-ref>netty</connector-ref>

                    <forward-when-no-consumers>true</forward-when-no-consumers>

                    <max-hops>1</max-hops>

                    <discovery-group-ref discovery-group-name="dg-config"/>

                </cluster-connection>

            </cluster-connections>
