[jboss-jira] [JBoss JIRA] Updated: (JBAS-3587) Add a system property to configure TCPPING.initial_hosts

[Brian Stansberry (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBAS-3587?page=all ]

Brian Stansberry updated JBAS-3587:
-----------------------------------

    Fix Version/s:     (was: JBossAS-4.0.6.CR1)

Only for 5.0 as this kind of config only makes sense with the multiplexer.  If two separate TCP channels used the same property, that would make a mess.  

For 4.0.x users of course can create their own property and add it to their config files; we just won't ship with the config files already set up that way.

> 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 system property to allow this to be externalized from the xml file, e.g:
> <TCPPING initial_hosts={${jgroups.tcp.initial_hosts:localhost[7800]} ...
> For now I'm going to go with just a system property.  If people want a startup switch they can request it.
