Oracle RAC的全称为Oracle Real Application clusters,在此前称之为OPS,是一个计算环境,通过它,用户可以充分利用多个使用集群技术互联的计算机的处理能力.Oracle Real Application Clusters通过简单轻松地使用单一系统影像的方式可以没有任何限制地利用集群环境的硬件资源来为任何打包应用和客户应用进行计算资源的扩展和提供高可靠性.Oracle Real Application Clusters允许在一个集群配置的环境中使用多个节点来访问一个单一的数据库,从而防止应用和数据库用户由于硬件或是软件导致的操作失败,并且能方便利用硬件的扩展来提高系统性能.
