In general, Oracle 11g R2 RAC provides the following features: High Availability: shared-everything mode ensures that services are not stopped when a single node fails, and other nodes in the cluster will take over quickly Scalability: multiple nodes share the load and can provide processing capabilities far beyond that of a single database. Addition and deletion of nodes can be completed online without downtime Ease of use: multiple databases ca

Oracle RAC Full name: Oracle Real Application Clusters, that is, Oracle Real-Time ApplicationProgramCluster, so that different applications can access multiple Oracle instances as if accessing one Oracle instance (of course, the performance is horizontally Scalable), and nodes communicate through private network; all operations are recorded through log files and stored on shared devices. They can be read, written, and synchronized by all cluster node

Failover Discussion When designing an application with the opportunity RAC, developers and designers need to face the fact that even the best hardware is not 100% reliable. Using RAC can reduce the impact of instance faults, but some additional measures are required on the application end to shield the impact of faults on the application. However, not all applications support
