After installing and configuring the Oracle client software, as Bill mentioned, you will also need to provide sufficient permissions to the Oracle Home folder, especially in the case of an ASP.NET app:

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
Information Server (IIS)) through any of the following programmatic interfaces

1. Oracle Provider for OLE DB
2. Microsoft OLE DB Provider for Oracle
3. Oracle ODBC Driver
4. Microsoft ODBC for Oracle
5. Oracle Objects for OLE (OO4O)
6. Microsoft .NET Framework Data Provider for Oracle

you may receive one of the following errors:

(1) Oracle Provider for OLE DB

(a) Error Type: Microsoft OLE DB Service Components (0x80070005)

Access is denied.

(b) OraOLEDB.Oracle Provider is not registered on the local machine

(2) Microsoft OLE DB Provider for Oracle

(a) Error Type: Microsoft OLE DB Provider for Oracle (0x80004005)

Oracle client and networking components were not found. These
components are supplied by Oracle Corporation and are part of the
Oracle Version 7.3.3 or later client software installation. Provider
is unable to function until these components are installed.

(b) Error Type: Microsoft OLE DB Provider for Oracle (0x80004005)

Oracle error occurred, but error message could not be retrieved
from Oracle.

(3) Oracle ODBC Driver

(a) Error Type: Microsoft OLE DB Provider for ODBC Drivers (0x80004005)

Specified driver could not be loaded due to system error 5 (Oracle
in OraHome92).

(4) Microsoft ODBC for Oracle

(a) The Oracle(tm) client and networking components were not found.
These components are supplied by Oracle Corporation and are part
of the Oracle Version 7.3 (or greater) client software installation.

You will be unable to use this driver until these components have
been installed.

(b) Error number: -2147467259

Error Description: [Microsoft][ODBC Driver Manager] Driver's

(5) Oracle Objects for OLE

(a) while using a GLOBAL.ASA file

Error Type: Active Server Pages (0x0)

An error occurred while creating object 'OraSession'.

(b) not using a GLOBAL.ASA file

Error Type: Microsoft VBScript runtime (0x800A0046)

(d) System Error 998 trying to run ASP page

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.

Paul, I have a question regarding Oracle Objects (OO4O). I have seen many examples of vb6 with OO4O but haven't seen any examples for using OO4O with VB.Net. Any help in this matter will be appreciated.

I have a stored procedure in oracle that has 4 out parameters of type "pl/sql table" and would like to get them using vb.Net code. If you could think of any solution, please reply.

thanks

I haven't use OO4O with Visual Basic.NET/2005 but since it implements COM I would think that you could use interop. Have you tried running VB 6.0 sample code through the conversion wizard?

AFAIK, the PL/SQL table type is not supported as a parameter to a stored procedures when using either the Microsoft or Oracle .NET provider. The closest replacement would be a ref cursor.

I have seen this solution in a lot of places but it hasn't worked for me. I am currently running Visual Studio 2005 and SQL Server 2005 on a workstation (XP Pro SP2)to carry out testing for an upgrade path for our current reporting strategy.

I am able to build, preview and deploy the reports in Visual Studio, however as soon as I run the report in reporting services under IIS I get the following error.

• An error has occurred during report processing.
  • Cannot create a connection to data source 'metpro'.
    • System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.

I have carried out the orcale home folder security solution with no effect. I am not using the wondows integrated security option either in VS2005. It looks to me like the oracle client installed with oracle 9i on the workstation is not being used / pointed to. The path has been set to ensure this is not the case, so I am at a loss as to why I am still getting this error, any ideas?
