Re: DBLINK from Oracle to SQLserver

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.
