Hi merid888,
Config.ocio is a file package which contains references to a myriad of color lookup tables (LUTs), python configuration code, color spaces and ICC profiles included with a given ACES/OCIO installation. This file can be set up as an environmental variable so that any application on a given computer can access it, or it can be loaded individually into Octane.
For Final render output, again in the Main tab of the Octane Renderer settings, make sure the Buffer type is set to HDR (Float 32-bit) and the Color space is set to either ACES2065-1 or ACEScg. ACES 2065-1 is the full range color space, appropriate for Octane as it is a spectral renderer, whereas ACEScg is intended for RGB render engines, and is a reduced color space. Either will work, and most compositing applications can handle the ACES 2065-1 spec.
To download the OCIO file package, use the link above. You will need the contents of the entire archive for the config.ocio file to work properly and offer the various options.
