Oracle Real Application Clusters
Customers can use Oracle Real Application Clusters (RAC) to operate a single Oracle Database across several servers to increase availability and adaptability while using shared storage. During outages, user sessions connected to Oracle RAC instances may failover and securely replay modifications, masking the impact of failures on end-users.
Oracle RAC uses Oracle Clusterware as the basis to connect several servers into a unified system. Oracle Clusterware is a cluster administration system that works in tandem with the Oracle Database. It is also necessary for Oracle RAC to function correctly.
Real Application Clusters eliminate individual database servers as a single point of failure and provide customers with the best database accessibility. The database is shared over a pool of servers in a clustered server setup, suggesting that if one of the pool’s servers fails, the database will continue to work on the other servers.
Oracle RAC not only allows customers to continue preparing database workloads in the case of a server loss, but it also helps clients save money by minimizing the number of times databases are taken offline for scheduled maintenance.
Oracle RAC can scale up and down with you. One of its crucial characteristics is the possibility of having distinct configurations for each instance. That means an individual may quickly implement application partitioning, run an OLTP with some other instance, and manage each other instance in a way that fits their specific arrangement. All of this takes place in a single database.
Real Application Clusters (RAC) are Oracle’s solution for enterprises of all sizes. It provides scalability, competitive pricing, fast performance, and maximum user concurrency with 24×7 availability. Due to its structure, RAC is frequently regarded as the ideal choice for people with crucial databases.
