Help with Oracle 11g ODBC on Win Server 2008 R2

Posted on 2011-09-13
Last Modified: 2012-05-12
I'm setting up software on a server to connect to Oracle 11g running on AIX 6.1.  The server is Win Server 2008 R2 64 bit.  I downloaded and sucessfully installed Oracle client 64bit for windows.  I can connect with SQL plus and I can configure a system dns name to the Oracle database on the AIX server. I created the Oracle_Home variable on the server.   For testing I'm trying to connect MS Access 2003.  Access does not show the system odbc.  Any Ideas what I should do next?

The bit versions need to match.  If Access is 32Bit, you need the 32Bit Oracle drivers (I suggest the Instant Client and ODBC add-on available on the same Oracle download page).

Also there are two versions of ODBC administrator.  The 32Bit version is in a different folder:

Hello slightwv!  You have helped me in the past.  I'll take a look again at the downloads page and update my post with the results.

The instant client can be found here:

You will need two pieces:

Instant Client Package - Basic: All files required to run OCI, OCCI, and JDBC-OCI applications,325,016 bytes)

Instant Client Package - ODBC: Additional libraries for enabling ODBC applications,591 bytes)

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

For some reason I had to install the 32bit oracle client to get the oracle driver to show up for MS access.  It's working.  Thanks big time for your help!!!

Glad to help and that it is working.

Not sure why the Instant Client didn't work.
