fatal ni connect error 12170 Oracle Database Tips by Burleson Consulting November 5, 2015 Question: Below error getting in alert log file every day, but database is working fineWhat are the reason for this Fatal ni connect error 12170? Fatal NI connect error 12170. VERSION INFORMATION: fatal ni TNS for 64-bit Windows: Version 11.2.0.1.0 - Production Oracle Bequeath NT Protocol Adapter for 64-bit Windows: Version 11.2.0.1.0 - Production Windows NT TCP/IP NT Protocol Adapter for 64-bit Windows: Version 11.2.0.1.0 - Production Time: 28-MAY-2012 19:20:02 Tracing not turned on. Tns error struct: ns main err code: 12535 TNS-12535: TNS:operation timed out ns secondary err code: 12560 Answer: The fatal ni fatal ni connect 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 source and restrict access. Note that logged addresses may not be reliable as they can be forged (e.g. in TCP/IP).
