I've been asked to look after some WAS Portal servers here which are running in a cluster environment but not too sure if they're functioning correctly. Even reading the IBM documentation doesn't really clear up the problem. The deployment manager along with an application server, node agent and a portal server all run on one machine and can be accessed via the URL using the FQDN of that server. All of the other portal servers run on seperate systems with their own node agents and application servers and can be controlled by the deployment manager which looks all correct to me. The applications are deployed via the deployment manager which means that you can access the application server via any server but I was under the impression that in a clustered environment you should really only need to access one node and if that node is down then it would automatically swtich over to another one so basically the URL shouldn't matter, this doesn't seem to be case. Maybe I've got the wrong end of the stick and you can only access the applications but there is no dynamic switchover when a server goes down, there is only load balancing happening. Correct?
