Just a quick note note of the steps I took to setup a Oracle 11g ODBC connection on a Windows 7 desktop:
- Download the appropriate Oracle Instant Client
- Get the Basic and the ODBC zip files
- Unzip both into the same folder (e.g. C:\OracleInstantClient\ )
- Execute odbc_install.exe in the Instant Client Folder
- Change your System Environment variables:
- Add the Instant Client Folder to the path
- Create a ORACLE_HOME and add the Instant Client Folder
- Create a “network\admin” folder in the Instant Client folder and create your tnsnames.ora file in there, with the appropriate values.
- You are now able to create a DSN in the ODBC manager using the Oracle driver that uses the TNS names defined in the .ora file
Hope this helps someone
