I've been seeing alot of that lately.
Is there NAT involved between the client and server?
Does the oracle server have multiple network interfaces?

Typically, a 12535 occurs after the redirect is sent to the client.
The client can tnsping the listener, but never connects to the
dedicated server process that has been spawned for it.
