The Research On The Implementation Of Oracle Real Application Cluster (RAC) Deployment

Oracle Real Application Clusters (RAC) allows Oracle Database to run any packaged or custom application, unchanged across a set of clustered servers. This provides the highest levels of availability and the most flexible scalability. If a clustered server fails, Oracle continues running on the remaining servers. When you need more processing power, simply add another server without taking users offline. To keep costs low, even the highest-end systems can be built out of standardized, commodity parts.Oracle Real Application Clusters provides a foundation for Oracle’s Enterprise Grid Computing Architecture. Oracle RAC technology enables a low-cost hardware platform to deliver the highest quality of service that rivals and exceeds the levels of availability and scalability achieved by the most expensive, mainframe SMP computers. By dramatically reducing administration costs and providing new levels of administration flexibility, Oracle is enabling the enterprise grid environment. Oracle RAC11g Release2enables customers to build a dynamic grid infrastructure for their enterprise.This paper provides a technical overview of Oracle Real Application Clusters11g with the emphasis on the features and functionality that can be implemented to provide the highest availability and scalability for enterprise applications.
