Answer / Deepika Singh
Real Application Clusters (RAC) is a high availability and scalability solution for Oracle Databases. It allows multiple instances to access the same database on different servers, providing improved performance, reliability, and uptime. The main benefits are: 1. High Availability: RAC ensures that the database continues to run even if one or more servers fail. 2. Scalability: By adding more servers to the cluster, RAC allows for linear scalability. 3. Improved Concurrency: RAC eliminates contention at the physical I/O level, allowing for a large number of concurrent users.
