my Environment -------------------- 2 Postgres Servers v 8.3.1 1 JBoss AS 4.2.3 Setup ------ In my postgress-ds.xml, I've configured the datasource as HA-XA-datasource to use both servers. Problem --------- Now I want to get notified when one data base is down to intimate the clients that database is down. Is there any way to listen any such JMX notification that notifies about the database failover View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254079#...
