ASP.NET and Oracle connection error ORA-12154 -- kiran --


Hi All,

I've one ASP.NET code which uses ODP.NET for oracle connection. This code is working fine on my colleagues' machines but not on mine.
It throws an Oracle error: ORA-12154 TNS Name could not be resolved on objConn.Open()
I m able to connect to db successfully through TOAD. (TNSNAMES.ORA file is perfect)
I've also added access rights on Oracle directory for ASP.NET.
Through Oracle Adapter of .NET i m able to connect and view tables.
Please suggest on this.

Regards,
Kiran

Hey All,

Found the solution!!!

When I had given ASP.NET right on Ora92 folder, TNSNAMES.ORA file was absent. I had added it later on, because of which this file didn't have this right. As a consequence, .NET framework was unable to access this file to resolve TNS names.

Also found another thing on net that - if TNSNAMES resolving fails,
alternatively we can use these names' definitions directly in Connection String.
This gave me the hint to check access rights on TNSNAMES.ORA

Regards,
Kiran
