Good point. I'll move the comment.
Thanks so much. I would just hate to lose all of that great UDP tuning that has been added.
Although I agree that UDP makes JBoss Clustering MUCH easier I'm thinking of clients that might have network policies which disable or restrict UDP for whatever reason.
On another note, is there any discussion or possibility of moving the JGroups configuration which is currently in two separate files into one location? I know it might be an issue with classloading or the maintainence of the Tomcat package overall but it seems like it would be easier to manage large cluster configurations if this were in one location. I would imagine most JBoss environments end up configuring JGroups the same way in both locations.
JGroups 2.3 introduces the Multiplexer, which allows multiple services to multiplex on top of a single JGroups channel. In AS 5.0, the various clustering services will by default all run on a single multiplexed channel.
Even if you wanted separate channels, the protocol stack configurations for the channels will all reside in one place.
Due to backward compatibility restrictions, this kind of setup will not be the default in any 4.0.x release, although we are looking at making it an installer option.
Sounds great! Yet another feature I can't wait to see in v5!
