ORA-03134: Connections to this server version are no longer supported

By reading this blog you may save sometimes for download the unnecessary Oracle drivers for Visual Studio.

If you still have Oracle 9i and you want to download 32-bit Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio land at http://www.oracle.com/technetwork/topics/dotnet/downloads/odacmsidownload-2745497.html.

Do not download ODAC 12c Release 4 and Oracle Developer Tools for Visual Studio ( You will get the error “ORA-03134: Connections to this server version are no longer supported” after you installed no matter what.

If you think, you want to download older version close to Oracle 9i which is ODAC 10g. Don’t do that either because you will not be able to install it in your Windows 10.

Download the ODAC 11.2.

    I was using 11.2 version and everytime I attempted to connect it always showed some kind of warning which said that the installed driver wasn’t the recommended, it “allowed” me to connect nevertheless but the tables would not load. I try installing version 12 and now have the ORA-03134 error.
