Hi @jeesshnasree

Let's say you wanted to have 3 x Standalone Servers of JBoss EAP for some DevOps Reason.

1st Instance:

$ sudo -u jboss ./standalone.sh -Djboss.server.base.dir=/opt/jboss/standalone/

The management console at http://localhost:9990

2nd Instance:

$ sudo -u jboss /opt/jboss-eap-7.0/bin/standalone.sh -Djboss.server.base.dir=/opt/jboss/standalone2/ -Djboss.socket.binding.port-offset=10000

The management console at http://localhost:19990

3rd Instance:

$ sudo -u jboss /opt/jboss-eap-7.0/bin/standalone.sh -Djboss.server.base.dir=/opt/jboss/standalone3/ -Djboss.socket.binding.port-offset=10000

The management console at http://localhost:29990

This is just a useful parameter in JBoss EAP that you can set in order to avoid port conflicts on a system. In the above example, the 2nd and 3rd standalone instances will be listening on ports witht the offset i.e. 10000 ie. 19990 and 29990 accordingly.

Hope this helps.

Will
