Failover Clustering
Mrdenny, says that if a cluster resource is configured to failover then it will failover on an application program that fails, but does that make sense? if the application program failed processing a specific transaction on one server isn't it going to fail processing the same transaction on another server?

    I guess that depends on the type of failure. If it fails because of wrong data, for example, it will most likely fail again regardless of the server it is running on. But If it fails due to hardware problems or lack of resources it would make sense to move it to another server. The thing is, how are those failures going to be detected ? If something goes wrong, but the application continues running, is this really going to be detected as a failure and trigger a failover ?

    Carosdl, thanks for the response. I was thinking not so much of a data problem but a flaw in the logic of the program that when presented with a specific transanaction that is very rare it will fail. Failover in that instance solves nothing.
