ORA-03113: end-of-file communications channel

[paschwan]

we just migrated from ora 8.1.6 to ora 9i.

Unfortunately now we get often this ORA-3113-Error even when the application isn't doing anything. (sometimes after 1 hour running fine). Is there anything I can change from the client-side to prevent this disconnect ?
(I still have DOA 3.4.6.4, client is still Net8)

thanks, Patrick

ORA-03113 usually means that the Oracle Server process for the current session has crashed. Can you check if a user trace dump file exist on the database server that corresponds to this ORA-03113 error? Usually you will see an ORA-00600 error here, with some error codes that may help us find the cause of the problem. If it does, can you send it to me?
