【摘要】 高可用系统指通过高可用软件将一组服务器连接在一起,组成一个集群,通过快速地将用户、应用和数据从发生硬件或软件故障的机器切换至其他机器来提供高可用计算环境。HACMP是基于AIX平台的,在高可用系统层次实现关键性任务计算环境的系统软件。对HACMP技术及HACMP的组成及结构作了介绍,给出了HACMP集群的硬件构成以及用HACMP构建高可用系统的思路和办法,并以HACMP集群在社保信息系统中的应用,阐述了高可用主机系统在信息化建设中的作用。更多还原

【Abstract】 High Availability System refers to a group of servers connected together to form a cluster through high availability software,through rapid customer, applications and data from hardware or software failures occurred in the machine switched to other machines to provide high availability computing environment. HACMP is the system software for AIX platform crucial in achieving high availability system-level computing tasks.This paper presents the HACMP technology, the composition and structure of HACMP,and presents the hardware and uses HACMP clusters of ideas and ways to build high availability system,Finally this paper explains the HACMP clusters and information systems of social security in a high availability server system expounded on the role of information technology.更多还原
