集群、备份和容灾技术在医院信息系统中的应用

The Appliance of Cluster/Backup/ Disaster Tolerant in Hospital Information System

着重介绍了网络环境下医院信息系统的安全保障体系,详细讨论了集群、备份和容灾技术在医院信息系统中的作用。首先,应对医院业务系统和数据库建立一个高效的、全冗余的热切换容灾系统;其次,对医院信息系统环境和数据库进行多重备份,以保证数据的完整性;另外,还要建立一个异地容灾系统,当主服务器系统出现故障时,可以即时进行切换。

This article outlines the methods of how to build a safe environment for hospital information system （HIS）, and discusses the function of cluster, backup and disaster tolerance in HIS. Firstly, It is recommended to build a high available and redundant hot spare system for program applications and database; Secondly, to make several copies he current database; Finally, the method lies to prepare an emergent server in another building, thus, once there were some problems with the main server system, the emergent sever would take over it and make the whole system works well.
