Oracle Real Application Cluster

Oracle has been a leading relational database vendor for over two decades. They have been very responsive in meeting the ever-rising data needs of enterprises. Oracle has implemented many innovative, practical and useful features in their database systems. Oracle Database has been the leading choice for many large database systems. Oracle?s Parallel Database systems are particularly suitable for complex database processing, and for providing high availability and scalability needs.

The Explosive Growth of Business Data

The need for high quality business data is exploding. In the mid-eighties databases much larger than a couple of gigabytes were rare and qualified as very large databases (VLDB). Now, normal databases are in the multi-gigabyte range and the VLDB domain doesn't start until the terabyte range, with petabyte databases on the horizon.

In traditional sectors of the business market, new needs drive the requirement for more data. Data warehouses provide access to historical sales, production, and cost information allowing detailed analysis of trends and more accurate predictions of future growth and sales. New business sectors such as wireless data are experiencing explosive growth, with the number of wireless data users predicted to grow to at least 24 million by the end of 2003 (Source: VB.NET Advisor Zone, Enterprise Business to Drive Wireless Data Market Growth). The tracking of usage data in telephone, cell phone, and wireless industries creates millions of new records in a day?s time. In traditional business sectors such as the paper industry, the product is tracked from manufacture - how many board feet of lumber or how many tons of pulp are obtained from each tree, to endpoint ? which truck delivered which order at what time, to sales ? how profitable was the wallboard segment in relationship to manufacturing plant "A". All of this is business data and it is growing at an explosive rate in all business segments.

Business Data = Corporate Asset

The events of September 11, 2001 underscored the importance of treating corporate data as a critical company asset. Many companies experienced set backs to business operations because they lost not just personnel, but all of their corporate data when the World Trade Center was destroyed. Protecting business data and ensuring that it is always available has become a paramount issue in the modern world.

In too many companies corporate data resides in data islands or, if you prefer, stovepipes. These isolated data segments serve the needs of a limited number of personnel and may have the most up-to-date information or contain information that is woefully out-of-date. Other companies may have a consolidated database system, but they are poorly designed, inadequately maintained, and difficult to use.

In order to provide value to a business, data must be both available and timely. To be available, the database must be properly designed and maintained. For data to be timely, it must be clean, consistent, and well organized.

Modern database systems offer the means to provide both availability and timeliness for business data. Oracle offers the Real Application Clustering Technology (RAC) that will ensure that business data can be placed in its most accessible form, maintained in its most timely state, and provide nearly 100% availability.
