RE: DBLINK from Oracle to SQLserver

Sorry, forgot to add other useful information.

Oracle 9iR2 on w2003
SqlSever 2008 on W2008.

I followed all of the steps I found in the white papers. The only difference was that I used NT authentication when I setup the ODBC connection (using my credentials) and then a supplied username and password from the Sqlserver side for the link creation.

I've not used the database owners credentials yet, but that may be the next setup. Gonna recreate the ODBC DNS entry with the same credentials as the dblink and see what happens.

I'll look at oracle gateway but don't think we are going to have the budget right now for another licensed option in Oracle...

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.
