[jboss-dev-forums] [Design of Clustering on JBoss (Clusters/JBoss)] - Some cluster enhancements...

[ScottMarlowNovell]

Hi,

I have been working on a few small enhancements, some of them are complete and some need more work.  I would like to check in the following changes into some 4.x or 5.x release if we agree that the changes are good:

1.  new HAPartition methods for calling a specific cluster targetNode (identified with opaque server reference that is currently a org.jgroups.stack.IpAddress).  This was useful for sending messages to a specific target node in the cluster.

2.  A load balancing policy based on FirstAvailable that always favors a same machine choice.

3.  A load balancing policy that always picks the ha-singleton server (depends on ha-jndi and a server side ha-singleton).

The hapartition ehancement is minor and easy.  The other changes are additions so they shouldn't break anything.

I have a ejb enhancement as well but I'll post about that in ejb design forum.

Thoughts?

Scott
