Purpose of Oracle Real Application Clusters (RAC)

What is the main purpose of Oracle Real Application Clusters (RAC)?

- Oracle Real Application (RAC) provides the interaction of executable file with the Oracle database.

- It allows the running of any packaged or custom built application with the Oracle database that is running on a server pool.

- It provides very high level of availability, flexibility and scalability to run the application and store it to the database.

- It creates the database such that if the pool fails then the database is continued to run from the remaining servers and the load can be distributed.

- It makes it easier for the administrator to maintain many servers at the same time by load-balancing techniques and providing provision to add more and more servers when the load increases.
