Service Interruption

[wobbet]

If I re-deploy an application will services be interrupted or does JBoss know that it needs to finish what it is currently doing while not allowing new connections and then re-deploy. And if it is part of a cluster is it smart enough to know that it should take itself out of the cluster so it doesn't accept requests, upgrade itself, and then propogate its changes to the rest of the cluster or will all services in the cluster be temporarily disrupted when re-deploying?

if you update your EJB on one node of the cluster, JBoss will wait for currently executing invocations to finish and redirect newly comming invocations to other nodes.

In a cluster situation I deploy to only one node in the cluster and allow JBoss to deploy to the other nodes. Will JBoss wait to deploy to the other nodes of the cluster until after the current deployment has finished or does the entire cluster get deployed at the same time?

Will JBoss halt incoming connections on the machine being updated?

Will replication to the remainder of the cluster happen while the first node is being updated or only after the update has completed?
