Before You Connect

To connect to Oracle, you must first update the appropriate environment variable. This variable must contain a folder location that includes the Oracle OCI Library assemblies, which are shipped alongside the driver.

The correct environment variable depends upon your platform:

• Windows: The native libraries should be on your PATH. Note that the VC++ 2017 Redistributable package is required to load the OCI libraries.
• Mac: The native libraries should be on your DYLIB_LIBRARY_PATH.
• Linux: The native libraries should be on your LD_LIBRARY_PATH.

These native libraries can be found in the lib folder inside the installation directory of the driver.

The NativeFolder property specifies the path to the directory that contains the native DLLs. By default, the driver uses the system’s standard library-loading policy. You can specify either a full or relative path. On Windows and macOS, setting this property is a viable alternative to setting up environment variables.
