JBoss EAP 7 Standalone TCP clustering not working with two different physical node

[msdhu264826]

JBoss TCP clustering is working when running two instances in the same physical machine. But when running it from the different physical node with the same configuration, each JBoss instance started the separate cluster, not joining the same cluster. I have updated the bind address as same as machine IP of the corresponding node.

Attached the standalone-ha configuration and server logs from both the nodes. Please let me know if I miss any configuration.

Hi,

Can you confirm if telnet is working between both physical machines.

Also please make sure that there is no firewall between these machines and iptables are stopped.

Please try to use below command to telnet from 1 physical machine to 2nd:

~~~

telnet IP PORT

~~~

Please let us know if this is working.

Hi Arnav,

Thanks for the response.

There is no firewall between both the nodes and iptables are stopped. Following is the result is telnet from machine 1 to 2 and vice versa.

[root@machine1 jboss]$ telnet 10.15.197.102 7600

Trying 10.15.197.102...

Connected to 10.15.197.102.

Escape character is '^]'.

Connection closed by foreign host.

Hi Madhu,

Thanks for confirmation.

Can you also confirm if "mfaportal.war" is a clustered application ?

By clustered application I mean if there is a <distributable/> tag in your web.xml file ?

Right, make sure the server logs indicate that the cluster has been formed, i.e. jgroups receives a view with more than the current member.

Hi Arnav,

I have <distributable/> tag in my web.xml and following replication configuration in jboss-web.xml

<replication-config>

    <replication-granularity>SESSION</replication-granularity>

</replication-config>
