Problem:

oracle client to oracle server, oracle server deployed in fwsm inside zone (fw mode router); client can access the server, but after some time oracle will report" ora-03114-no connected to oracle error".Did not occur before installing fwsm.

fwsm and 6509 switches is the routing model; firewall has config "no inspent sqlnet“and Strategy  permit ip any any?

Where does the problem occur?
