Hi i used to run Oracle9i database,
Recently, i install an Oracle 10g database

Then due to some tidy up reason, i remoeve all my current db connections from my SQL developer and try to create new ones using my current 9i tnsnames.

However when ever i choose the tnsname option in SQL dveloper, i saw the list that belongs to 10g which contain nothing as i has setup nothing in the tnsname files of 10g yet.

So what can i do to let SQL developer detect my old tnsname in oracle9i network folder instead of the 10g one.

I have try to look at my system environment variable it is as shown as below

c:\DevSuiteHome_1\OUIHome2\bin;c:\DevSuiteHome_1\jdk\jre\bin\classic;c:\DevSuiteHome_1\jdk\jre\bin;c:\DevSuiteHome_1\jdk\jre\bin\clie nt;c:\DevSuiteHome_1\jlib;c:\DevSuiteHome_1\bin;c:\DevSuiteHome_1\jre\1.4.2\bin\client;c:\DevSuiteHome_1\jre\1.4.2\bin;C:\oracle\prod uct\10g\bin;c:\oracle\product\9.2\db\bin;C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program Files\Oracle\jre\1.1.8\bin;C:\oracle\product\10.2.0\db_1\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\QuickTime\QTSystem\

All my oracle path are set to the bin folder, how does SQL developer detect my my new 10g tnsname file
through registry ?

Any gurus guide me pls ? i need to revert back to my 9i tns name file.

thanks

You can simply COPY the tnsnames.ora file from the V9 directory on top of the V10 tnsnames.ora file.

(You said Registry, so I assume you are using some version of Windows):

Define an environment variable named TNS_ADMIN (cam be done in the registry or in some control panel wizard -- can't remember exactly where, and I'm not booting out of Linux just to find out).

Set that variable to be wherever you want your tnsnames.ora file to be. Make it a fully qualified directory name (start with C: or D: or whatever you use).

Then, all your Oracle clients will use this tnsnames.ora file: 9i, 10g, whatever. Once you are certain that it is working (always test) you can delete the surplus tnsnames.ora files.

You had oracle 9i installed and then you had installed oracle 10g. So now the ORACLE_HOME is pointing to oracle 10g. That is why you are getting oracel 10g's tns entries.
You need to reset ORACLE_HOME variable value.
Reset it from command prompt the to value of oracle home directory of 9i, or you can also use the "Oracle Home selector" utility (start menu -> oracle instalation products -> Home Selector).

Hope this helps you..

Dipali.
