Oracle RAC (Real Application Clusters)

Oracle RAC (Real Application Clusters) is a technology that allows multiple servers (computers) to work together as a single system to run an Oracle database. This setup improves performance, scalability, and availability because if one server fails, others continue to operate without interruption. Think of it like a team of experts managing the same workload, sharing resources seamlessly. This ensures that the database remains accessible and efficient, even during high demand or hardware issues, making it ideal for large enterprises that require continuous, reliable data access.
