Good day!

We are preparing a script for purposes of cold backup.
We have already listed the Oracle binary files except for
the tnsnames.ora and the password file.

Can someone help me show tnsnames.ora path using SQLPlus?

Thanks in advance.

You Can`t.
As it will reside on both client and Server side of the Database.
You can find the path @ %ORACLE_HOME%\network\admin\

You can have one chance.

execute the following ...
step 1) Using SQL*PLUS
select '&_connect_identifier' from dual;

SQL> select '&_connect_identifier' from dual;
old   1: select '&_connect_identifier' from dual
new   1: select 'SATYA' from dual

'SATY
-----
SATYA

Step 2
go to command prompt and type tnsping <result of the step 1>
ex: sql> ! tnsping satya

Just tried to help you.

Good luck

Thanks for this info.

Actually, one of our outsourcers recommend inclusion of tnsnames and password file.

Again, thank you very much!

Though: if there is more than one Oracle software product installed on your computer, there's a good chance that you'll have multiple TNSNAMES.ORA files. Which one do you need? One of them? All of them? Some of them?

Moreover: \network\admin is the default location. TNSNAMES.ORA can be located anywhere (mine is, for example, in "c:\oralib" directory (MS Windows)). Its location can be defined by the TNS_ADMIN environment variable, so all my Oracle products use that TNSNAMES.ORA (and not the ones located in their \network\admin directories).

So, consider that fact as well.

Ofcourse But if you ping the TNS Entry it will give you the path no matter where it resides...

Right; didn't read your message carefully enough, sorry. TNSPING will display it under "Used parameter files".
