cover is so vast that it can seem a bit intimidating. Fortunately, the creative nature of the product allows every table and data set to be as complex as the user desires it to be. Still, this range of components can lend itself to a variety of errors. For the sake of simplicity, it helps to break these errors down into two sets:

those that occur in the data/coding, and those that pertain to software/network settings. The ORA-03135 is an error that stems from the latter. 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 correcting it. The Solution The best place to start is by diagnosing the error. To do this, begin by checking if
session was terminated. 2) Check if the timeout parameters are set properly in sqlnet.ora.

by the firewall when connecting remotely. To resolve ORA-03135 exception we need to increase the value of the ora-03135 connection lost contact in datastage expire_time parameter in theSQLNET.ORAfile, as mentioned in Action part. We can also set the parameters sqlnet.inbound_connect_timeoutand inbound_connect_timeout_listenername to 0 can avoid the ORA-03135 error. SQLNET.ORA file is located under https://www.tekstream.com/resources/ora-03135-connection-lost-contact/ $ORACLE_HOME/network/admin/. 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 http://nimishgarg.blogspot.com/2015/04/ora-03135-connection-lost-contact.html to SQLNET.ORA 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.

It works fine for really small files (<5 KB), but for larger ones (e.g. 44 KB) I get an error: "ORA-03135: connection lost contact". I don't think it's timing out, as the exception occurs within a second of executing the command. I tried setting connection lost contact both of the following in my connection string, but to no avail: Validate Connection=true Pooling=false I also looked in the listener.log file on the remote machine. It shows the connections being made, but no sign of exceptions or terminated connections. I'm up for suggested fixes or troubleshooting methods. Edit: The same SQL operations work when accessing an Oracle instance on the local network. c# oracle odp.net share|improve this question edited Jan 5 '14 at 19:07 Guido Leenders 2,0921828 asked Aug 28 '12 at 16:12 Ishmael Smyrnow 6491623 Well maybe it is not that, but I had the "ORA-03135: connection lost contact" on weird stuff when the connection was not lost at all it only happend that Oracle was no longer able to swallow the SQL statement submitted. I got it on huge queries (>2000 line of code). Maybe I am sending you on the right track but I thought after 4 hours no answer I at least could tell you that piece of my own experience. For me it looked like the message always appears when the parser of the SQL command crashed in the background. –hol Aug 28 '12 at 20:47 Might be worth checking the alert log on the remote machi
