I've setup and maintain a few similar configurations with Oracle DB on
Linux, HP-UX and Solaris.
There is some issues related to 32 and 64 bit drivers but most of them (unfortunately not all) are solved by Oracle Gateway 4 ODBC in release 11.2.
Do you need any technical advice or just recommendation ?
I can agree with rest of people that doing this same from MS SQL side is more easy, and maybe you can push our data from MS SQL to Oracle but in that case you have duplicated set of data.
