1. Re: Can JBoss support active/passive
brian.stansberry Apr 26, 2007 5:50 PM (in response to wangdongfox)For web requests, mod_jk can support that (in your mod_jk conf, comfigure disabled=true for a worker to passivate it).
For EJB requests you'd need to implement some kind of custom LoadBalancePolicy; there's no out of the box support for it. -

Is There any doc about Active - StandBy configuration for clustering ???

brian.stansberry May 2, 2007 11:30 AM (in response to wangdongfox)wangdongfox, for the use case you describe you could deploy the MDB in the deploy-hasingleton directory. That's not a true active/passive because the bean is not deployed and passively waiting to receive messages. Instead it will be deployed and begin receiving messages if the master node fails or is shutdown. I would expect that for most MDB use cases that would be sufficient, since a messaging based app by definition doesn't assume the message receiver is always available.
