Oracle OCI Driver Setup
This procedure installs the the Oracle OCI drivers globally, which means that the drivers will be available for all users on the machine.
We recommend installing the Oracle OCI drivers (and other database drivers) in the correct/default global driver directories for your operating system. However it is possible to install drivers locally (for a single user) if you wish to restrict access.
Do not install Instant Client drivers if Oracle and/or the Instant Client drivers are already installed!
To check, use File Explorer to search for the tsnnames.ora file. If this file exists, speak to your DBA (database administrator) to identify the correct course of action.
