can anyone help me?
I've seen rumors that oracle clustering doesn't actually work, perhaps due to problems like this. It looks like an oracle problem. What is supposed to happen to a jdbc connection to a clustered server when one of the cluster members goes down? If the connection is supposed to stay live and seamlessly connect to another cluster member, it looks like this is not happening and oracle clustering in fact doesn't work. If it is supposed to die and you are supposed to get a new connection that will connect to another cluster memeber, you will have to take account of that in your application code.
