      Hi,

       

      I am new to jboss.

      I have just migrated jboss application to new server linux. The application started up fine if only 1 node started up but when 2nd node started up, it throws exception.  I am seeing the below

      The 1st node cannot be seen in node 2.

      Thanks for any advise or help on this.

          How do you start JBoss and where are the two instances located?

          Do you use the default configuration with JGroups UDP-multicast configuration?

          Often the issue is that multicast is blocked by the network

            Hi Fink,

            Thank you for your reply.

             

            The two instances located at 2 different server with respective IP. Since 1st node is the main, I started node1 then node2.

            I can see the two IPs listed in JMX-Console under same partition.

            I used the default configuration with JGroup UDP-muticast configuration but the UDP and partition name is changed in setenv.sh

             

            Regards,

            Vimala

              If you change the UDP and partition name the servers are separated and not building a cluster, this is the expected behaviour!

              Also you did not show an Exception as mentioned in your first comment.
