我院主机系统设计方案

Design plan of our hospital's server system

为确保医院信息系统安全可靠的运行 ,我院针对医院信息系统的特点 ,提出了一套切实可行的主机系统设计方案。文章就此方案的关键技术问题阐述了双机容错技术 ,对ROSEHA容错软件的机制进行了说明 ;分析了RAID技术的实现方法及磁盘阵列的应用 ;说明了VERITASBackupEXEC软件的工作原理 ,介绍了对ORACLE数据库的在线备份方法及备份策略 ;

To guarantee the safe and reliable operation of its information system, our hospital, in light of the features of HIS, came up with a feasible design plan for the server system. The paper discusses the fault tolerant technique, the key technique involved in the plan, explains the mechanism of the ROSE HA fault tolerant software, analyses the implementation method of the RAID technique and the application of the disc array, describes the operating principles of the VERITAS Backup EXEC software, introduces the on line backup method and strategy for the ORACLE database, and illustrates the implementation method of the banking of the central servers dual systems and the configuration of relevant hardware.
