摘要
高校数据中心对各类异构的业务系统进行整合,实现了数据的共享与集成,为了保障数据的有效性和一致性,需要建立具有高性能、高可靠性的数据库集群系统。结合西安邮电大学校园网实例,分析了Oracle RAC的运行机制与关键技术,利用其Failover和Load Blance节点进行了部署和配置。经过实际运行,这种双机数据库集群模式运行状态稳定,能够有效解决高并发访问情况下的单点瓶颈问题。
The data sharing and integration were achieved by integration of various heterogeneous business systems of universities data centers. In order to guarantee the effectiveness and consistency of the data,the high performance and high reliability database cluster system needs to be established. In combination with the instance of campus network in Xi＇an University of Posts Telecommunications,the operational mechanism and key technology of Oracle RAC are analyzed,and deployed with its Failover and Load Blance user nodes. The actual operation shows the running status of this dual-mechanism database cluster mode is stable,and single point bottleneck problem in case of high concurrent access can be effectively solved.
