Jboss Clustering over TCP
 

Hi

I am not sure whether this is the right forum to post, sorry if this the wrong form....
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
<Config>
<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"/>
</Config>

and in server2, the bind_addr="server2" and TCPPING initial_hosts="server1[7800]" port_range="3"

This didnt work... the nodes didnt see each other in this case.... Apart from cluster-service.xml , are there any other files which needs to be looked into as well???

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
<Config>
<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"/>
</Config>

The same config on both the servers. But this config gives me errors while starting. I have attached the error file for that.

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
