Our database is behind a firewall. Firewall has an "idle session timeout" value. If a connection remains idle for more than the "idle session http://hemora.blogspot.com/2013/05/how-to-resolve-tns-12535-or-tns-00505.html 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 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.

A great post.I had the same problem with an Oracle 12.1.0.10 and I have solved adding SQLNET.EXPIRE_TIME = 10 in the last line of file SQLNET.ORAThanks! 19 June 2015 at 07:59 Anonymous said... how to check

It generally starts with the Application Team working on the client error, but soon ends up at a dead end. Months pass with no clear solution in sight as the sporadic nature of the errors make it very time consuming to troubleshoot. In this particular case an opened case with Oracle resulted in finger pointing. More resources are assigned to solve the issue, from the network and security teams but each an expert in their own domain. A problem that spans across multiple domains, requires these teams to build bridges to identify and define the issue in pursuit of finding a solution.
