基于Oracle RAC数据库集群系统研究与实现

Research and Implementation of Database Cluster System based on Oracle RAC

为了打破“信息孤岛”进行数据交换,实现数据共享,进一步提升高校教育信息化管理及应用水平,从数据层着手构建全校统一数据中心库,基于数据库共享技术打破“信息孤岛”。考虑到数据中心库高性能、高可靠、易扩展的实际需求,选择了Oracle RAC数据库集群系统,分析了RAC基本原理、体系结构与关键技术,并结合实际情况构建数据中心库,为学校信息数据的交换、整合提供有效途径,也能为后来者的研究提供参考。

In order to break the"information island",carry out data exchange,realize data sharing,and further improve the level of educational information management and application in Colleges and universities,starting from the data layer,the unified data center database of the whole school is constructed,and the"information island"is broken based on the database sharing technology.Considering the actual needs of high performance,high reliability and easy expansion of data center library,Oracle RAC database cluster system is selected.The basic principle,architecture and key technologies of Rac are analyzed.The data center database is constructed according to the actual situation,which provides an effective way for the exchange and integration of school information data,and also provides some reference for later research.
