Hello Im using two machines : Windows XP and Windows Server 2003 , on both I have installed the oracle client 10g, and when I try to use ODBC for linked server option on SQL Server It just work on my XP but on the server I cant get it work, even with the same configuration.

Note:

Windows XP - SQL Server 2008 Developer Windows Server 2003 - SQL Server 2000 Standard

Will be the SQL Version?

Thanks.

in Both machines I get the same tnsnames.ora file:

# tnsnames.ora Network Configuration File: C:\oradata\client\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

MEDICAL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = SERVERCONTABLE.RESOCENTRO.COM)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = medical)
    )
  )

but with diferent install dir.

What are the errors that you're getting from the linked server on the Windows 2003 box? –  squillman Jan 19 '10 at 19:20
    
I've added the error stack –  Angel Escobedo Jan 19 '10 at 19:38
    
Ok, that's not going to get us far. What happens if you run your statement through SQL Server Management Studio (logged in as the user that your app is connecting with)? –  squillman Jan 19 '10 at 19:42
    
look I cant use the SSMS for anything about that linked server, But I can work with tnsping and connect via prompt sqlplus in Windows Server 2003, I have checked Allow in process also and users are correct in security options –  Angel Escobedo Jan 19 '10 at 20:00
    
Check the last edited post please, thanks –  Angel Escobedo Jan 19 '10 at 20:53

No, it's not likely to be because of the version of SQL. The most frequent error I get setting up linked servers to an Oracle target is an Oracle name resolution error. Check to make sure that your tnsnames.ora has the same entry on the Windows 2003 server as the XP machine has. The tnsnames.ora file is typically located in

\[oracle install root]\product\[version]\client_x\NETWORK\ADMIN

Where version is the version of Oracle and client_x is the instance of the client installation you're working with.

SOLUTION :

Edit or Add new REG_DWORD called AllowInProcess and set Hexa value as 1

RUN> regedit > HKEY_LOCALMACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\[Version]\Providers\OraOLEDB.Oracle
