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

Problem Description  
  
-------------------  
  
When running an application using the Oracle9i Release 2 (9.2.0.1.0) install  
  
of client software and that attempts to connect to an Oracle database with the  
  
Authenticated User privilege (such as when you use Microsoft's Internet

Solution Description  
  
--------------------  
  
Oracle 9.2 Client software requires that you give the Authenticated User  
  
privilege to the Oracle Home by following these steps:  
  
1.  Log on to Windows as a user with Administrator privileges.  
  
2.  Launch Windows Explorer from the Start Menu and and navigate to the  
  
ORACLE_HOME folder.  This is typically the "Ora92" folder under the  
  
"Oracle" folder (i.e. D:\Oracle\Ora92).  
  
3.  Right-click on the ORACLE_HOME folder and choose the "Properties" option  
  
from the drop down list.  A "Properties" window should appear.  
  
4.  Click on the "Security" tab of the "Properties" window.  
  
5.  Click on "Authenticated Users" item in the "Name" list (on Windows XP  
  
the "Name" list is called "Group or user names").  
  
6.  Uncheck the "Read and Execute" box in the "Permissions" list under the  
  
"Allow" column (on Windows XP the "Permissions" list is called  
  
"Permissions for Authenticated Users").  
  
7.  Re-check the "Read and Execute" box under the "Allow" column (this is  
  
the box you just unchecked).  
  
8.  Click the "Advanced" button and in the "Permission Entries" list make  
  
sure you see the "Authenticated Users" listed there with:  
  
Permission = Read & Execute  
  
Apply To = This folder, subfolders and files  
  
If this is NOT the case, edit that line and make sure the "Apply onto"  
  
drop-down box is set to "This folder, subfolders and files".  This  
  
should already be set properly but it is important that you verify this.  
  
9.  Click the "Ok" button until you close out all of the security properties  
  
windows.  The cursor may present the hour glass for a few seconds as it  
  
applies the permissions you just changed to all subfolders and files.  
  
10.  Reboot your computer to assure that these changes have taken effect.  
  
Re-execute the application and it should now work.  
  
Explanation  
  
-----------  
  
If you install Oracle9i Release 2 (9.2.0.1.0) on a computer running Windows  
  
with an NTFS partition, the contents of ORACLE_HOME directory will not be  
  
visible to users who are authenticated on that machine.  These permissions  
  
were not set properly when the software was installed.  
  
Applications that were working fine with previous versions of Oracle software  
  
will stop working when they upgrade to Oracle 9.2.  
  
NOTE: The application will continue to work if the user has logged onto the  
  
machine as an Administrator.  
  
Any application that is using the Authenticated User privilege will not work.  
  
A notable example would be IIS which might service some of the requests based  
  
on the Authenticated User privileges.  
  
To demonstrate the problem in further detail, you can log on to the operating  
  
system as an authenticated machine user.  You won't be able browse the contents  
  
of the ORACLE_HOME directory demonstrating your inability to load any Oracle DLLs  
  
or make a connection.  
  
Additional Information  
  
----------------------  
  
The above error messages may not only be encountered when using Oracle 9.2  
  
client software but may also exists when running into general permissions  
  
issues using third party products on a Windows platform.

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

¤  
  
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.
