Jboss Eap - mod_cluster - to prevent jboss talking to each Other

Question

I have a jboss setup with 2 jboss instances on one VM. Each of the 2 jboss talk to 2 apaches on same VM.

jboss 2

     <subsystem xmlns="urn:jboss:domain:modcluster:1.1">
          <mod-cluster-config advertise-socket="modcluster" connector="ajp" proxy-list="192.168.1.2:6263" balancer="box2_cluster">

            <remote-destination host="localhost" port="25"/>
        </outbound-socket-binding>
    </socket-binding-group>

The apache works well and connect to jboss .The apache also detects all deployed apps.

Questions:-

When the

192.168.1.2:6262/mod_cluster-manager is done it shows the applications deployed on the 2nd jboss. I want to make sure that the apache 1 detects application that are deployed in jboss 1 and no other applications. Basically i want to use mod_cluster but dont want one jboss to talk to another.I want to use mod_cluster for jboss to autopublish applications to apache.But i dont want 2 jboss to talk to each other.

Answer 1

If you do not want two JBoss instances cross talk (since they are not in the same cluster) then you should have the 2 nodes listen on unique multicast addresses.

By the way, if you do not use clustering you are losing the ability of session replication and high availability.
