server.I've finally found what was causing the problem. 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 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 firewall idle session timeout bcos I have same issue 15 July 2015 at 08:47 Kiquenet said...

Note: Prior to 11gR1 these same ‘Fatal NI connect error 12170' are written to the sqlnet.log Cause These time out related messages are mostly informational in nature. The messages indicate the specified client connection (identified by the ‘Client address:' details) has experienced a time out. The ‘nt secondary err code' identifies the underlying network transport, such as (TCP/IP) timeout limits after a client has abnormally terminated the database connection. The ‘nt secondary err code' translates to underlying network transport timeouts for the following Operating Systems: For the Solaris system: nt secondary err code: 145: ETIMEDOUT 145 /* Connection timed out */ For the Linux operating system: nt secondary err code: 110 ETIMEDOUT 110 Connection timed out For the HP-UX system: nt secondary err code: 238: ETIMEDOUT 238 /* Connection timed out */ For AIX: nt secondary err code: 78: ETIMEDOUT 78 /* Connection timed out */ For Windows based platforms:
