Any performance tuning service provided by Oracle Support?

My client possesses a vast amount of retail data combined with a highly complex data model, resulting in numerous intricate data intersections.

The whole process of loading data from source, allocate and calculate data with multiple models and sending data to reporting cubes with complex mapping for a period requires more than 12 hours.

Is it possible to request Oracle technicians to review potential areas for performance optimization or to allocate additional processing power to a specific application instance?
