There are some free drivers available TDS is one I believe for Linux. Data direct will give you a 15 day trial then you have to cough up the $$ I didn't have any issues with the TDS driver for 32 bit in the past. HS works fairly well depending what you want to do. If you are on 64 bit you need to use dg4odbc for HS and that works with 10g upward. For 10G you need to install the 11G gateway. You might want to play with DTS from the Sql Server side of things as well. I haven't used it but we do use it at work and it works very well.

HS or generic connectivity requires the use of an ODBC driver for the database server platform designed to access SQL Server. The only platform I believe that comes with such a driver is Windows so extra cost is probably required unless you are capable of writing your own ODBC program. On the other hand the Oracle client for Windows is free and MS on 32 bit systems provides ODBC/OLE drivers to Oracle. For 64 bit Windows you need the Oracle 64 bit OLE driver. Pushing and pulling from the SQL Server side is free. -- Mark D Powell -- Phone (313) 592-5148 From: Jeffrey Beckstrom [mailto:JBECKSTROM@xxxxxxxxx] Sent: Friday, August 08, 2008 3:01 PM To: Powell, Mark D Subject: RE: connecting Oracle to SQL Server Are they extra costs options? >>> "Powell, Mark D" <mark.powell@xxxxxxx> 8/8/08 2:48 PM >>> Look into Generic Connectivity and Heterogeneous Services on metalink.
