1 ora-3113 errors have numerous causes.
2 Many of those causes have nothing to do with the network, but with the application.
3 One common cause is problems with the shared pool 4 In a normal configuration you don't have 3113's 5 So: Yes, you can and should eliminate them 6 You are probably not searching in the right direction now
