What does the article that you provided the link give me, in terms of an answer to my question.

Question
Error 7399: OLEDB Provider 'MSDAORA' reported an error
I want to set up a linked server on SQL Server 2000 which is running on a Win2k Advance Server.
The linked server I want to setup is required to link to an Oracle 7 database that is sitting on a WinNT4.0 server.
Below is what I have done on the SQL Server server.
1. Installed the Oracle client version 7.3.4
2. Setup the linked server on SQL Server - I am using MS OLE DB Provider for Oracle as the Provider name.
3. Although setting up the linked server gives me no problem, clicking on either TABLEs or VIEWS in this linked server gives me the error above (in the title - Error 7399: ...).
Is there something that I am missing out that will make my linked server to work? Your help will be appreciated.

Hi,
This is my experience for installing link server for oracle, for your reference only.
Mine is using Oracle 9i, i think it should be no problem with other versions; Also i am using Microsoft ODBC for Oracle:
1. tnsnames.ora
Install Oracle 9i Client
Modify the tnsnames.ora under c:\orant\network\admin
MOON81.XXXX.COM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = moon)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = moon81)
)
)
moon81 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = TCP)
(Host = moon)
(Port = 1521)
)
)
(CONNECT_DATA = (SID = moon81)
)
)
Notes:
1. This is Oracle 9i client, so got to have both Service_name and SID
tnsping moon81
2. set up link server
EXEC sp_addlinkedserver @server = 'moon', @srvproduct = 'MSDASQL', @provider = 'MSDASQL',
@provstr = 'DRIVER={Microsoft ODBC for Oracle};SERVER=moon81;UID=
go
sp_addlinkedsrvlogin 'moon', false, NULL, 'readonly', 'readonly'
Good luck!!!
rmission: Article tells about problem fields.
Oracle 8.x-specific data types, such as CLOB, BLOB, BFILE, NCHAR, NCLOB, and NVARCHAR2, are not supported.
( sure your database contains some text or nvarchar fields )
The Unicode feature against Oracle 7.x and 8.x servers is not supported.
( this is about nvarchar or ntext fields )
If you have some batch statetements in VIEWS or stored procs - it not supported also.

HOW TO: Set Up and Troubleshoot a Linked Server to Oracle in SQL Server
http://support.microsoft.c
I thought it would be very helpful for you.
Thanks to both LazyStudent and xxq4813. My problem is now fixed. And yes, the fix included:
1. Installing Oracle7 Client on the SQL Server machine
2. Setting up alias in TNSNAMES.ORA that pointed to the Oracle instance I wanted to link to.
3. Installing MDAC 2.7 (2.5 would have suffice in my case too).
I have decided to share the 400 points equally among LazyStudent and xxq4813.
Thanks again.
