Toad startup issue version 8.0

Hi All,

I am using toad 8.0 in my project . when i start toad application it is creating a folder under Program Files with name as Tnsnames and it has two files in the folder, sqlnet.ora and tnsnames.ora.

\Program Files\Tnsnames.

It is trying to the load the tnsnames.ora from this location, and it displays an error when i try to connect to oracle server .

ORA-12154: TNS: Colud not resolve service name.

if i delete this folder from the Program files, and try to connect it works(Since toad now is looking for the tnsnames,ora file in the Admin folder.)

Please help in understanding why this tnsnames dir is created at toad startup and how to make toad to refrain from doing so.

Thanks,
Thomas Reddy

Which version of the Oracle client are you using? And also the operating system
in use could be an issue.

SQLNet setup and/or configuration (e.g. tnsnames.ora) is not Toad specific. If
you have a standard SQL
net home setup say as
c:\oracle\product\11.2.0\client_1\network\admin then simply on the Toad
connection screen tell Toad to use the default SQLNet home. You do not need a
special copy for Toad placed anywhere. If you do not have a SQN
Net setup and
simply wish to use Oracle’s instant client – that too does not need
to be under Toad directory. You simply place it both on your path (for DLL
resolution) and set TNS_ADMIN to point to the dir so that essentially becomes
the Oracle home. Of course trying to use an old version of Toad (Toad 8.0 is
from 2004) is not advisable – upgrade. For example that version of Toad
may not recognize Oracle 11g client since it did not come out until 3 years
after Toad 8.0. And using an old client with newer database may not support all
the newer data types that you may want to use.

Saying 9i does not really answer the question. 9i could mean 9.1.x which is no
longer supported by oracle or 9.2.x which is. Then is it 9.2.0.5 or greater
– which again is the currently orcle supported/recommended versions. You
need to be far more specific. Also – here is a blog I wrote some time ago
about common Toad to Oracle connection issues – which are 99.99% of the
time improper standard oracle client setup - and not toad issues ….
