What do I need to install on Windows 2008 server to be able to create an Oracle ODBC connection

I need simple instructions on what to download from Oracle to be able to install the Oracle ODBC driver to permit connectivity to an Oracle database from a server application.  Server only has a SQL server option to install now.  Server is 64 bit.  Do I need to install both 64 bit and 32 bit connectivity?

I would go with the Instant Client.

You'll need two files.  The 'Basic' and the ODBC add on.

Instant Client Package - Basic
Instant Client Package - ODBC

>>Do I need to install both 64 bit and 32 bit connectivity?

The bit version you need to install depends on the Bit version of the software that will be using it.  32Bit apps need the 32Bit driver and visa versa.

Also note that windows 64Bit has two different ODBC admin tools:

You may not need an Oracle client at all.  Windows and/or SQL Server likely include a client to connect to Oracle, so you may be able to use this Microsoft client to create an ODBC connection to Oracle.  I've used both Microsoft and Oracle clients in the past to create ODBC data connections to Oracle databases, and they have both worked for me.  I understand that one may work better than the other if your Oracle database uses some of the newer or less-common datatypes and/or database features.

Unless things have changed:
I'm pretty sure the Microsoft drivers sit on top or Oracle drivers.  Microsoft has even de-supported them.

The only way I know of to connect to an Oracle database without an Oracle driver is the JDBC Thin connection or 3rd party products that sort of have the 'client' built in.

Did you install the ODBC drivers?  Looks like only the OLEDB drivers are installed.

The BAT file that comes with the ODBC instant Client lets you choose what to install.

Make sure you are running the correct Bit version of ODBC Admin for the Bit version of Oracle driver that you installed.
