Listen on one port, service request on multiple servers

Question

we are migrating off oc4j to Weblogic 10.3.
One of the things that we really really liked about oc4j was the ability to distribute our applications across multiple JVMs, but refer to any of the apps with the same hostname and port; this meant that we could change the distribution of the applications over the JVMs and not touch the URLs used to access those applications. We would do this to isolate troublesome apps from other ones, and to keep JVM size reasonable.
With WebLogic, our understanding is that only one managed server can be accessed on a given host/port, and a managed server is one JVM. Does this mean that we will need to either put all our apps into one JVM, or else change URLs as the we move apps from one managed server to another?

Answer 1

1 yes, the dhcp server who's scope is full will not do a dhcp
'offer'
2 dhcp that answers fastest with a 'offer' will win. A delay is configurable (but changes nothing
about the root scenario were the fastest will win)
Note that if the scopes overlap on the servers, they might not lease out all the addresses in the scope.
I would enlarge the scope as you will want to fence against unavailability of one of the servers (or a network connection for that matter). you currently have more addresses leased out than any set of two of your servers can offer.
