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 the OS PID (OS Process Identification) still exists. Use the ps -ef|grep syntax to do so. From there, check to make sure that the Network Address Translation between the client and the server also still exists. If neither of these seems to be the source of the problem, it could be that a firewall is the source. If you are using Windows,

OS Windows 2003 server Database Oracle Database 10g Standard edition version one Hi, I have installed oracle database http://dbaspot.com/oracle-server/401648-ora-03135-connection-lost-contact.html on machine M1 and on second machine M2 installed oracle client. http://www.freelists.org/post/oracle-l/Database-hangingcrashing-repeatedly Created one service on M2 pointing to Oracle database on M1. Started SQL*Plus UI on machine M2. Executed some query on SQL*Plus UI on M2 which return result successfully. SQL*Plus UI remain opened on machine M2 for 2 hours. After that when I executed same connection lost query, SQL*Plus report error "ORA-03135: connection lost contact". This problem occurs frequently. My problem is that why I am getting error "ORA-03135: connection lost contact when I kept open SQL*Plus UI for two hours. It will be great if some one help me to resolve issue.

Wed, 5 Oct 2011 23:39:10 -0500 One of our databases has been crashing in the same fashion repeatedly and sounds like the root cause is the same but not sure what exactly is causing it. Suddenly the database starts hanging. No user can login and gets the error (ORA-03135: connection lost contact). When I try to login as sysdba it hangs and never gets connected to the database. Grid control monitoring receives the error (Failed to connect to database instance: ORA-03135: connection lost contact (DBD ERROR: OCISessionBegin). On each occasion of such hanging(crash) we had to reboot the server(database host). It happened on Sept 23, 2011 and then it happened on Oct 05, 2011 within two weeks. When we bounced the database there were some WARNING in alert log. => WARNING: AQ_TM_PROCESSES is set to 0. System operation might be adversely affected. Warning reported in the alert log before the hanging => WARNING: inbound connection timed out (ORA-3136) Database version: 10.2.0.4 Server: Sun M3000 (SunOS 5.10 Generic_142900-13 sun4u sparc SUNW,SPARC-Enterprise) Memory: 16GB Any tips to investigate the root cause will be appreciated.
