Hi all,

We are planning on interfacing Oracle to SQL server connectivity, I'm researching on how to create a dblink to SQL server 2005. I'm a little confused between Generic connectivity and Transparent Gateways..

I think Transparent Gateway is not free and needs to be licensed, is it better interms of performance? Also, do I need to configure this gateway on a seperate server?
I think Generic connectivity can be configured on the same Oracle database server itself.. but I see there could be some performance issues with it..

We are running on Oracle 10.2, looks like HSODBC is not available in 10g?

Please help me..Thanks a lot

A transparent gateway is a gateway that is designed for accessing a specific non-oracle system.with these database, you can use an database server to access data anywhere in a distributed database system without needing to know either the location of the data or how it is stored.
In addition to transparent gateways,there is a set of agents that comprise the oracle generic connectivity feature.these agents contain only generic code and customer is responsible for providing the necessary drivers.Generic connectivity has some limitations. The ODBC and OLEDB gateways have to be installed in the same oracle home directory as the oracle database server. connecting to one of these gateways from another oracle database server is not supported.

It is, at least on Windows.
