File or assembly name Oracle.DataAccess not found.

I am trying to deploy an ASP.NET solution using ODP.NET to a server and
receive the error:

File or assembly name Oracle.DataAccess, or one of its dependencies, was not
found.

I see the Oracle.DataAccess.dll in the Oracle_Home\bin directory and Other
OLE access to Oracle is working just fine using the same Oracle_Home.

How does my ASP.NET application determine where to locate the required
Oracle.DataAccess files? What else do I need to do be able to make my ASP.NET
applications work using the Oracle .NET provider?

Much Thanks - Stan

I have changed the permissions on Ora817 folder under program files and
that has not helped. Any clue why this must be happenning..

THanks a bunch
 
Nik -

Did you set security for the Oracle dll's as Paul has outlined? That has
cured my problems in the past with the Oracle issues...

¤ Thanks Paul.
¤
¤ Yesterday, I installed the ODP.NET and used these setup steps from your
¤ previous posts and got the app working. I believe my issue is the Instant
¤ Client not supporting the .NET.
¤

Yes, the instant client does not provide nearly enough functionality.

¤ Is there any easy way to tell what Oracle client is installed on the server?
¤

You can probably look at the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE Registry key. Just keep in mind that
it is possible to have more than one Oracle client installed at the same time.

Yeah, I would check the information from my first reply to verify that everything is configured
properly with respect to permissions.
