[jboss-user] [Clustering/JBoss] - Re: Clustering NOT working on physical separate boxes.

[rajeshchande]

Hello Brian,

As suggested I tried changing the PING and GMS parameters as below in both cluster-service.xml and tc5-cluster-service.xml, keeping other things as before:

            <config>
  |                     <UDP bind_addr="172.17.132.140" mcast_addr="228.8.8.8" mcast_port="45577"
  | 		.....
  | 		... />
  |                 <PING timeout="300000" num_initial_members="3"
  |                     up_thread="false" down_thread="false"/>
  | 		....		
  |                 <pbcast.GMS join_timeout="50000" join_retry_timeout="2000"
  |                     shun="true" print_local_addr="true"/>
  | 		.....
  |             </config>

The nodes (devl-01 and devl-03)on different servers still dont join each other. Instead the merging also is now not happening after the above changes. 

The outputs from each of them is as follows:

output from devl-01 on server-1:
