1. Re: Clustering Confusion

2. Re: Clustering Confusion
teknokrat Mar 11, 2005 5:08 AM (in response to teknokrat)Yeah, I've been at looking at it. What I don't understand is where the MDBs come into it. Does it mean the MDBs reside on the same servers as the JMS queue/topic? If so, how is load balancing handled?
There is an example onthe wiki on " Load-balanced, faul-tolerant MDBs in HAJMS" which I am reading now. Are there any other sources of information on this topic?

Not necessarily. You can put the MDBs on same server as the JMS queue/topic, but you can also put them on other servers in the same cluster.
My question is: how can you configure the MDBs to reconnect automatically when the JMS server fails over to another JBoss instance? See

I looked at that http://wiki.jboss.org/wiki/Wiki.jsp?page=LoadBalancedFaultTolerantMDBs too and downloaded the http://wiki.jboss.org/wiki/attach?page=LoadBalancedFaultTolerantMDBs%2Fload-balanced-mdbs-example.zip but it doesn't seem to do too much other than specify the HA-JNDI port (i.e. port 1100 instead of the local JNDI port 1099), which is already done in jboss-4.0.1sp1/server/all/deploy/jms/hajndi-jms-ds.xml
Or did I miss something?
