摘　　要：文章阐述了Oracle双机热备和Oracle RAC集群部署的基本概念、体系结构、所实现的功能等。通过对2种集群进行稳定性、容错性、资源利用率、可扩展性及可维护性等全方位的比较,说明各自的优缺点,并介绍了湖北省电力公司采用Oracle RAC集群方案搭建松耦合系统数据库集群的情况。实践证明,系统运行稳定,效果良好。This paper elaborates on the basic concepts, systematic structure and realized functions of Oracle hot standby and Oracle RAC cluster deployment. The advantages and disadvantages of the two clusters are compared by their stability, faulty tolerance, resource utilization, expansibility and maintainability. It introduces the methods of using Oracle RAC cluster scheme to build a loosely coupled system database cluster in Hubei Electric Power Company. Practice proves that the system is stable and has good effect.
