[jboss-user] [Clustering/JBoss] - Jboss Clustering over TCP

[xav.vijay]

Hi 

I am trying to create a jboss cluster of 2 nodes.  Here is the setup required.

1. NodeA is on server1 on VLAN1
2. NodeB is on server2 on VLAN2.
3. No UDP Multicast traffic allowed.

What I have tried so far is ... in cluster-service.xml on both the servers

in server1

            <TCP bind_addr="server1" start_port="7800" loopback="true"
                 tcp_nodelay="true"
                 recv_buf_size="20000000"
                 send_buf_size="640000"
                 discard_incompatible_packets="true"
                 enable_bundling="false"
                 max_bundle_size="64000"
                 max_bundle_timeout="30"
                 use_incoming_packet_handler="true"
                 use_outgoing_packet_handler="false"
                 down_thread="false" up_thread="false"
                 use_send_queues="false"
                 sock_conn_timeout="300"
                 skip_suspected_members="true"/>
            <TCPPING initial_hosts="server2[7800]" port_range="3"
                     timeout="3000"
                     down_thread="false" up_thread="false"
                     num_initial_members="3"/>
            <MERGE2 max_interval="100000"
                    down_thread="false" up_thread="false" min_interval="20000"/>
            <FD_SOCK down_thread="false" up_thread="false"/>
            <FD timeout="10000" max_tries="5" down_thread="false" up_thread="false" shun="true"/>
            <VERIFY_SUSPECT timeout="1500" down_thread="false" up_thread="false"/>
            <pbcast.NAKACK max_xmit_size="60000"
                           use_mcast_xmit="false" gc_lag="0"
                           retransmit_timeout="300,600,1200,2400,4800"
                           down_thread="false" up_thread="false"
                           discard_delivered_msgs="true"/>
            <pbcast.STABLE stability_delay="1000" desired_avg_gossip="50000"
                           down_thread="false" up_thread="false"
                           max_bytes="400000"/>
            <pbcast.GMS print_local_addr="true" join_timeout="3000"
                        down_thread="false" up_thread="false"
                        join_retry_timeout="2000" shun="true"
                        view_bundling="true"/>
            <pbcast.STATE_TRANSFER down_thread="false" up_thread="false" use_flush="false"/>
         

and in server2, the bind_addr="server2" and TCPPING initial_hosts="server1[7800]" port_range="3".... everything else is same.

This didnt work... they didn't see each other. is there any other file which needs to be modified apart from cluster-service.xml???

More info on the servers.... I can ping server1 from server2 and vice versa
I am connecting to server2 from server1 via ssh and vice versa is also possible.

I tied the following config as well...instead of using the multicast over UDP, I tried multicast over TCP
        
            <MPING timeout="2000"
                bind_to_all_interfaces="true"
                mcast_addr="224.0.0.1"
                mcast_port="7500"
                ip_ttl="8"
                num_initial_members="3"
                down_thread="false" up_thread="false"/>
        

The same config on both the servers. But this config gives me errors while starting. 

More info.... 224.0.0.1 is the only multicast IP working in our environment. i can ping this IP from both server1 & server2. I dont know if I am missing something or doing something wrong. 
Are there any other files which needs to be changed? is it possible to cluster 2 nodes across different VLAN's?? 

I would greatly appreciate any help.

Regards

Antonio
