can 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 ora-03135 connection lost contact standby 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, b

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 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 http://stackoverflow.com/questions/12163370/ora-03135-connection-lost-contact-when-inserting-large-file 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 2,0341726 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 machine to see if that reported an error. If not it maybe points to the problem being at the client end, not the server. Also, are there any firewalls in the way, or anything else at network level that might have logs you can check? –Alex Poole Aug 29 '12 at 7:11 A network log would be helpful. The fire

Oracle 11.1+ database versions mask the "ORA-03135" error and return a result after the 5 minutes which may lead the DBA down the wrong path believing there is a problem connection lost contact with the database.

One of our applications is about to be hosted by the supplier which means it will become an oracle database. I have installed the oracle client middleware 11g both 32 and 64 bit onto the server and the 32 bit on my PC, which is an XP machine. When I try to create a report it appears to work in the query panel, but returns only around 750 results. When I try to run the report I get the following error. Database error: ORA-03135: connection lost contact Process ID: 19596374 Session ID: 89 Serial number: 16037 . (IES 10901) (WIS 10901) I have added the following to the SQLNET.ora file, but it doesn't make any difference. SQLNET.INBOUND_CONNECT_TIMEOUT = 300 SQLNET.SEND_TIMEOUT = 300 SQLNET.RECV_TIMEOUT = 300 SQLNET.EXPIRE_TIME = 50 I have checked the universe and this works fine using the current database which is SQL, but not on the hosted database which is Oracle. Any ideas?

Ask the DBA to look at what is happening on the Oracle side. Try creating a new test universe and see if the issue occurs there
