was repeating during whole day almost for every application 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 ns secondary err code: 12606 "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...

This does not correspond to the listener port. CHANGES No changes are necessary, but may have http://dbafoiz.blogspot.com/2015/03/12170-tns-12535tns-00505-operation.html recently upgraded the database to 11g release 1 or higher, or installed a new Oracle11g database and they are now visible in the alert log. Note: Prior to 11gR1 these same 'Fatal NI connect error 12170' are written to the sqlnet.log. This document describes a problem that arises when a firewall exists between the client and the database server. CAUSE We can search the listener log covering the same time period using this search criteria. (HOST=121.23.142.141)(PORT=45679) The 11glistener log in text format is located here: $ORACLE_BASE/diag/tnslsnr///trace/.log Again, this is the client's IP address and the unique ephemeral port assigned to the client for this connection. In this case, we findthat this connection was established at the listener at this timestamp: 22-FEB-2014 10:42:10* (CONNECT_DATA=(SID=test)(CID=(PROGRAM=)(HOST=__jdbc__)(USER=))) * (ADDRESS=(PROTOCOL=tcp)(HOST=121.23.142.141)(PORT=45679))* establish * test* 0 . Compare this to the event in the alert.log with special attention to the timestamp. The connection was dropped by the instance at22-FEB-2014 12:45:09or roughly 2 hours later.
