Not sure if this is what your are looking for:
But the ODBC drivers ship with SQL Server.
If you are in SQL Server and wanting to set up the correct connection you will need to go into design veiw (of DTS), and you can simply click and drag the proper connection property. In this case we would click on the new connection icon (if you into using the GUI) for Microsoft ODBC Driver for Oracle. In order to set up the connection properly you will need the server, username and password.
Hope this helps.
