中文摘要: OracleRAC 架构是从Oracle9i 开始采用的一项新技术,是高可用性的一种,也是Oracle 数据库支持网格计算环境的核心技术。RAC 的性能主要取决于Cache Fusion 的性能。通过分析Cache Fusion 的原理以及产生等待事件的原因,利用分区技术分散实例的数据请求,减少Cache Fusion 的压力,充分发挥了RAC 的性能。
Abstract:Oracle RAC architecture is a new technology which began to be used from Oracle9i. It is a kind of high-availability technology,and also is the core technology of Oracle database support for grid computing environment. The performance of RAC mainly depends on the performance of Cache Fusion. Through analyzing the principle of Cache Fusion and the reasons of generated wait events, and taking the advantage of Partition technology to scatter data request of instance, it can reduce the pressure of Cache Fusion, and fully play the performance of the RAC.
