TFM is the Heterogeneous Connectivity Administrator's Guide = http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96544/toc.h= tm. The architecture section = http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96544/tgvsg= c.htm#9790 is an excellent introduction. You have two paths to choose from in setting up Heterogeneous = Connectivity-- you can use Generic Connectivity or you can use on of the = Transparent Gateways. If you are using Heterogeneous Connectivity to = connect to a SQL Server database, you may want to consider using the = Oracle Transparent Gateway for SQL Server rather than using Generic = Connectivity. Oracle's Transparent Gateways are specific to one = database (i.e. SQL Server) rather than using the lowest common = denominator ODBC API that Generic Connectivity uses, but these gateway = products offer better performance and functionality than Generic = Connectivity. The difference between Oracle Generic Connectivity and = Oracle Transparent Gateway products lies in what you deploy for the = Heterogeneous Service Agent, so rather than deploying a Generic = Connectivity agent and configuring an ODBC data source, you would deploy = a Transparent Gateway agent that connected to the SQL Server database. = You can get more information on Oracle's Transparent Gateways at = http://www.oracle.com/gateways/. The downside of Transparent Gateways = is that they require an additional license.

I would like to know if anyone has done this using heterogeneous services and if yes would you please get me started at = least with the right links to RTFM. Anything additional will be gravy. We are = also looking at Golden Gate solutions (for Oracle to MS-SQL) and I'd = appreciate a feed-back, if anyone has had any experience with it.
