:) Reason: Available h/w resources. We have one dedicated physical server for running JBoss msg. Another physical server that hosts existing JBoss instance running some application. We want to use this second server runnign a passive JBossMsg instance. So in case when the dedicated JBossMsg goes down, then the second shared server can take the load temporarily automatically, till we bring back the dedicated up again. Oher reason would be that we bring down the dedicated JBossMsg server for OS level patching, essentially minimizing the app downtime and increase availablity.
