TNS: connection closed error Oracle tips by Burleson Question: I'm trying to connect to Oracle and I get oracle closed connection 17008 the ORA-12537: TNS: connection closed error. How do I fix an ORA-12537?Answer: The ORA-12537 is an informational error, and the "real" error is the secondary error message. ORA-12537 TNS:connection closed Cause: Normal "end oracle closed connection vendor code 17008 of file" condition has been reached; partner has disconnected. Action: None needed; this is an information message. The ORA-12537 error sometimes relates configuration issues in the sqlnet.ora, protocol.ora and listener.ora files. Verify that you service names match between your listener and remote client connect strings.This ORA-12537 can also happen if your firewall has disconnected idle connections.Also, the ORA-12537 sometimes happens in these cases: 1. You have

a path name that is too long for the Oracle TNS client. See MOSC note:263489.1. Since the iORA-12537 ssue is caused by a large connection string there are several workarounds for the issue. 1. Install the exe in a shorter named directory. 2. Modify the TNS Names entry so that it is shorter. 3. Replace domain names with IP Addresses if that shortens and vice versa. 4. Remove any parameters from the entry that are not needed. 5. Patch the Database Listener to the most recent version. References 2.

A pre-requisite for this was shutting down the database. Following install, I restarted the database but now cannot connect to it unless I'm connecting internally.

Replies Follow bill.romine / 13 Jul 2012 at 7:04pm TOAD and Backup Reporter use different Oracle clientlibraries to connect to Oracle. I suspectthis difference is exercising some problem.Unfortunately the ORA-12537 could point to a number of issues. I’m guessing that the problem here is thatyou have multiple Oracle homes on your desktop and Backup Reporter is using thewrong one. Can you try a few tests andlook at some things to help isolate the problem?You say you “try to register source manually”. I assume you mean that you enter thehostname, port, etc. parameter under the “Direct” tab when registering thedatabase. If not, this is worth atry. This could help eliminate thetnsnames file as a possible source of trouble.My thought here is that you may have multiple Oracle homes and perhaps BackupReporter is looking at a different one than TOAD.Next, tr
