I'm having a problem with "idle sessions" being dropped by our Firewall. When a database client connects to Oracle 10g sitting behind the firewall all is good and fine. But when the database client goes idle for 10 minutes, the Firewall sees no traffic and drops the connection.
I added "sqlnet.expire_time=2" to the sqlnet.ora configuration file but with no effect whatsoever.
Does anyone have any ideas or thoughts to resolve this problem?
