Try to install more than one server on a single host.
The problem is two JBoss can not share the same port.
I did my homework and spot the following ports I have to change for different server instances.

port 8083 for [org.jboss.web.WebService]
port 1099 for [org.jboss.naming.NamingService]
port 8082 for JMX http adaptor
port 1476 for Hypersonic
port 8090 for jboss.mq:service=InvocationLayer,type=OIL
port 8091 for jboss.mq:service=InvocationLayer,type=UIL
port 4444 for EJB container invoker
Can someone with the experience confirm if it is enough to change the ports in *-services.xml and standardjboss.xml?
Can multiple servers installed on the same host in this way be in the same cluster?

Is any additional change needed?

Thank you in advance.
