Oracle RAC

Oracle Real Application Clusters (RAC) is a high-availability database solution that allows multiple instances of Oracle Database to run on a cluster of servers, accessing a single shared database. It provides scalability, fault tolerance, and load balancing by enabling transparent application failover and parallel processing across nodes. RAC is commonly used in enterprise environments to ensure continuous database availability and performance under heavy workloads.
