Description: RAC (Real Application Clusters) is a database clustering solution that allows multiple instances of Oracle Database to run on different servers, providing high availability and scalability. This technology is essential for enterprise environments that require constant and reliable access to data. RAC enables database instances to share the same storage, facilitating data management and improving performance. One of RAC’s most notable features is its ability to balance the load among instances, optimizing resource usage and minimizing downtime. Additionally, RAC provides effective disaster recovery, as if one instance fails, others can continue operating without significant interruptions. This is especially critical in applications that require continuous uptime, such as financial or healthcare systems. In summary, RAC not only enhances the availability and performance of databases but also offers a robust solution for data management in distributed environments.
