The negative of this kind of error is that it can happen to any user, whether working with complex table setups or not. The positive is that there are a few basic strategies that can be employed to counter this error. The Problem An ORA-03135 error reads as the “connection lost contact”. This means that the server connection was unexpectedly terminated or forced to terminate. This can also mean that the server simply timed out the connection. The error often occurs when connecting from a remote location and the firewall in your network terminates the connection. While this overall cause is fairly straightforward, the unfortunate aspect of the ORA-03135 is that there are a number of approaches to the solution, each dependent on the situation. Let’s take a look at how to properly diagnose the ORA-03135’s cause and some of the methods for

SQLNET.ORA file is located under $ORACLE_HOME/network/admin/. https://www.tekstream.com/resources/ora-03135-connection-lost-contact/ Following is the Oracle Documentation having lists and description of sqlnet.ora file parameters - http://docs.oracle.com/cd/E11882_01/network.112/e10835/sqlnet.htm#NETRF182 We recently faced ORA-03135 on one of our testing environment after Server Admin team did a firewall upgrade. Users were able connect to the database, but if their session was idle for some time, the connection was getting terminated. To resolveORA-03135we added following to SQLNET.ORA http://nimishgarg.blogspot.com/2015/04/ora-03135-connection-lost-contact.html file SQLNET.EXPIRE_TIME = 10 This keeps connections alive by send a check to verify that client/server connections are active in every 10 minutes. If the probe finds a terminated connection, or a connection that is no longer in use, then it returns an error, causing the server process to exit.

I'd also look at firewall connectivity between your sqlplus client and the db server.Norm Like Show 0 Likes (0) Actions 2. Re: Keep Getting Connection Lost Oracle Error ORA-03135 Simon.H Mar 7, 2013 4:03 AM (in response to normpang) I agree about the firewall - 1h is very common, e.g. the default timeout for Cisco ASA etc is 3600 seconds.If it's between a java application server, like WebLogic, and the database I usually set SQLNET.EXPIRE_TIME = 30 or 10 (minutes - default is 0) in sqlnet.ora on the database servers. This tells the database process that the client is connected to to send a little "ping" packet every 30 mins.See: http://docs.oracle.com/cd/E11882_01/network.112/e10835/sqlnet.htm#BIIEEGJHHope this helps Like Show 0 Likes (0) Actions Go to original post Actions Remove from profile Feature on your profile More Like This Retrieving data ...
