TNS:operation timed out ns secondary err code: 12560 Answer: The fatal ni connect error 12170 is related to the ORA-12170 error: ORA-12170: TNS:Connect timeout occurredCause: The client failed to establish a connection and complete authentication in the time specified by the SQLNET.INBOUND_CONNECT_TIMEOUT parameter in the sqlnet.ora file. This error may be a result of network or system delays, or it may indicate that a malicious client is trying to cause a denial-of-service attack on the database server. The server shut down because connection establishment or communication with a client failed to complete within the allotted time interval. This may be a result of network or system delays; or this may indicate that a malicious client is trying to cause a Denial of Service attack on the server.Action: If the error occurred because of a slow network or system, reconfigure one or all of the parameters SQLNET.INBOUND_CONNECT_TIMEOUT, SQLNET.SEND_TIMEOUT, SQLNET.RECV_TIMEOUT in sqlnet.ora to larger values. If a malicious client is suspected, use the address in sqlnet.log to identify the so

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 / Workaround: 1) 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. **In an installation that includes GRID, this parameter sho
