摘　　要：目的:基于Oracle RAC和DataGuard技术构建医院高可用HIS系统,保障HIS业务系统平稳运行,生产数据安全可靠。方法:运用RAC技术在医院数据中心部署HIS系统作为主库,同时在异地数据中心部署DataGuard作为备库,主库LNS进程实时传输HIS主库在线以及归档日志至DataGuard备库进行日志重演,实现数据备份。结果:整套系统的设计无单点故障,将容灾和备份相结合,将二者融为一体。结论:通过RAC和DataGuard技术构建的HIS系统可以有效地减少医院HIS系统宕机率,是行之有效的高可用建设方案。Objective:Based on Oracle RAC and DataGuard technology,we build our highly available HIS system to ensure the smooth operation of HIS business system and the safety and reliability of production data.Methods:Using RAC technology to deploy HIS system as the main library in our data center,and dataaGuard as the repository in the offso-location data center,transmitting THE main library online and archived logs to DataGuard repository in real time through ORACLE Net network,the repository log receiving process RFS saves the master library log to the local,and the log application process MRP implements log repetition in the DataGuard host to achieve data backup.The DataGuard host is also managed through Data Guard Broker,and the RAC master library is automatically Failvoer repository in the event of a failure.Results:The whole system is designed with no single point of failure,which combines disaster tolerance and backup to combine the two.Conclusion:The HIS system built by RAC and DataGuard technology can effectively reduce the downtime rate of hospital HIS system,and is an effective high-availability construction scheme.
