                 Key: JBAS-3587
                 URL: http://jira.jboss.com/jira/browse/JBAS-3587
             Project: JBoss Application Server
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Clustering
            Reporter: Brian Stansberry
         Assigned To: Brian Stansberry
             Fix For: JBossAS-5.0.0.Beta, JBossAS-4.0.6.CR1


As discussed on conf call, we want to make it easy to switch from a UDP-based JGroups config to a TCP-based one.  With the multiplexer this can be as simple as switching the multiplexer stack name in the various config files. One thing that makes the switch a pain is the need to configure initial_hosts in TCPPING.  We should make a startup switch and system property to allow this to be externalized from the xml file, e.g:

<TCPPING initial_hosts={${jboss.tcp.initial.hosts:localhost[7800]} ...

Should discuss on the forum whether we want a startup switch or just a property set via -D.  My preference is a switch.
