RAC Training

Real Application Clusters harnesses the processing power of multiple interconnected computers. Real Application Clusters software and a collection of hardware known as a cluster unite the processing power of each component to create a robust computing environment.

Real Application Clusters is a breakthrough cluster software architecture with scalability and high availability features that exceed the capabilities of previous Oracle cluster-enabled software products. Real Application Clusters offers significant advantages for all system types. With the increased functionality of Real Application Clusters, all systems and applications can efficiently exploit clustered environments.

The Benefits of Real Application Clusters

Lower Overall Cost of Ownership

Real Application Clusters lowers the overall cost of ownership more effectively than other cluster database products. This is due in great part to the single-system image afforded by the Real Application Clusters architecture.

Expanded Scalability

A scalable environment enables you to improve performance and add capacity by adding nodes. On some platforms you can add nodes dynamically while your cluster is running.

High Availability

High availability refers to systems with redundant components that provide consistent, uninterrupted service, even during failures. In most high availability configurations, nodes are isolated from each other so that a failure on one node does not affect the entire system.

Transparency

The concept of transparency implies that Real Application Clusters environments are functionally equivalent to single-instance Oracle database configurations. In other words, you do not need to make code changes to deploy applications on Real Application Clusters if your applications ran efficiently on single-instance Oracle configurations.

Buffer Cache Management

Oracle stores resources, such as data block information, in a buffer cache that resides in memory. Storing this information locally reduces database operations and disk I/O. Because each instance has its own memory, Real Application Clusters coordinates the buffer caches of multiple nodes while minimizing disk I/O.

Row Locking

Oracle row locking and multi-version read consistency provide a high degree of concurrency and throughput. Row locking ensures that transactions that modify different rows in the same data block do not need to wait for each other to commit.

Multiversion Read Consistency

Multiversion read consistency ensures that read operations do not block write operations and that write operations do not block read operations. Multiversion read consistency creates snapshots or read consistent versions of blocks that have been modified by a transaction that has not committed.

Recovery Manager, Online Backups, and Archiving

Real Application Clusters supports the full functionality of Recovery Manager (RMAN) and Oracle Enterprise Manager. Real Application Clusters also supports all Oracle backup and archiving features that are available in single-instance Oracle databases.
