Oracle Gateway is a separately licensable option I think (I know it used to be).

Looks like you are using the generic ODBC driver.  Install the Oracle gateway 
to SQL Server.  I just did that a couple of weeks ago myself and it works like 
a charm.  The documentation that comes along with the product is good too.  It 
is the 5th CD  in the 11g CD Pack.
