I am trying to connect from Oracle 10G(on UNIX) to a SQL Server database (On windows). I have looked at the manual and i will admit that i am finding the documentation quite
I used Data Direct drivers which had to be configured on the Oracle UNIX machine. You must create the ODBC connection in UNIX in order to be able to see SQL Server. (At least that has always been how I have done it)
In order to create a database link to SQL Server, you have to enclose your connect name and password between double quotes, like below:
create database link mysqlink
connect to "myuser" identified by "mypassword" using 'servername';
