How is clustered database important in Oracle RAC architecture?

- Clustered database is just like a single database accessed by multiple instances that are running on the server.

- The instances are being run separately or individually on the server pool and when the demands rise they are shifted to acquire more space according to the requirements.

- Clustered database provides dynamic access to the database and on the demand of additional resources they are added to the server pool.

- If one cluster is taking up the load then that load is shared between other clusters running on the server and the application services are provided in a much faster and better way.

- This also allows the adding of additional resources dynamically to the server pool with no downtime and the application starts running soon it is deployed on the server.
