Description Martin Svehla 2014-04-18 12:28:19 UTC 
The chapter should contain at least:
- configuration of broadcast group, discovery group and cluster connections
- server-side load balancing
- working with jgroups
Comment 1 Martin Svehla 2014-05-20 06:58:30 UTC 
Here's link to upstream documentation on HornetQ clustering: http://docs.jboss.org/hornetq/2.3.0.Final/docs/user-manual/html/clusters.html
Comment 6 Miroslav Novak 2014-06-16 09:13:41 UTC 
Hi Nidhi,

there is one more issue in configuration of clustering using JGroups. For broadcast group there should be:

                <broadcast-groups>
                    <broadcast-group name="bg-group1">
                        <jgroups-stack>udp</jgroups-stack>
                        <jgroups-channel>udp</jgroups-channel>
                        <broadcast-period>2000</broadcast-period>
                        <connector-ref>
                            netty
                        </connector-ref>
                    </broadcast-group>
                </broadcast-groups>

and for discovery group:
                <discovery-groups>
                    <discovery-group name="dg-group1">
                        <jgroups-stack>udp</jgroups-stack>
                        <jgroups-channel>udp</jgroups-channel>
                        <refresh-timeout>10000</refresh-timeout>
                    </discovery-group>
                </discovery-groups>

Attribute jgroups-stack - The name of a stack defined in the org.jboss.as.clustering.jgroups subsystem.

Attribute jgroups-file cannot be set in EAP 6 and all occurrences (paragraphs) must be removed.

For HornetQ in EAP we don't support chain cluster topology. I'd like to remove it from doc from chapter - 19.5.1. About Server Side Load Balancing:
Chain cluster: In a chain cluster, each node in the cluster is not connected to every node in the cluster directly. Here the nodes form a chain with a node on each end of the chain and all other nodes only connect to the previous and next nodes in the chain. To create a chain cluster, node A would define a cluster connection that connects to node B, and node B would define a cluster connection that connects to node C. The messages will move from node A>B>C in this case. The attribute max-hops is set to 2. 

Thanks,
Mirek
