Real Application Clusters enables enterprises to build databases across multiple machines providing a highly available and highly scalable architectures. If a single machine fails, then the system continues to run on the remaining servers. When additional capacity is needed additional servers can be introduced without taking users offline.
Our customers depend on Oracle Real Application Clusters for High Availability and Scalability and have benefited significantly by migrating from traditional, high-end SMP platforms to lower-cost, standardized grids of Intel-based servers running Oracle 10g/11g on Linux.
What is Real Application Cluster (RAC)?
A cluster is a group of independent servers cooperating as a single system. A RAC RAC the Oracle Instance (processes and memory structures that allow access to the data) are separated from the Oracle
An Oracle RAC database is a single database that can be accessed by multiple Oracle Instances. Each instance can run on a separate node within the cluster. Oracle RAC 10g benefits from this topology providing high availability, workload distribution, increased manageability and security features.
