Our database is behind a firewall. Firewall has an "idle session timeout" value. If a connection remains idle for more than the "idle session timeout" value it drops the connections.Application developers usually configure their connection pools to remain alive for a long time, which is more than the "idle operation timed out session timeout" value of the firewall. Not all the connections in the pool are used. Some stays idle. After sometime the firewall drops them and I get those operation timed out problems.Solution:Add the following line to the sqlnet.ora file on the server.SQLNET.EXPIRE_TIME=10In this configuration database will probe the application servers every 10 minutes to see if they are up. In fact this is a mechanism to determine stale connections by database. Because it sends packets to application servers every ten minutes, the connections are detected as active by firewalls and they are not broken.
