dickson1888, your suggested configuration is very common. By the way, if one app hangs (or crashes) on the app server, it will not affect other application. Actually, it probably will not even affect that one application, only that thread for that application. App servers are built to be resilient and tolerant of most app problems. Of course there are exceptions such as memory leaks that affect all apps. In addtion, if you have to reboot the app server to fix an issue with an app, then you will affect all apps.
