高可用性是基于网络的电子商务系统的关键要素.文中首先介绍了一个用于日本药局的商务系统OPEN-STOCK,重点给出了它的高可用性解决方案,介绍了该方案中各类系统信息的作用范围,定义了商务系统服务状态相关的参数表,给出了负载平衡的三种调度算法,以及网络系统参数获取和系统服务状态侦测的实现方法.该方案具有规模可调整以及面向应用的特征,它通过实现负载平衡以达到系统的高性能,并支持容错而获得系统的高可靠性.该电子商务系统及其技术已经在日本市场投入应用,并达到了设计目标.%High availability is a critical mission for business system. At first, an instance of business system OPEN STOCK for pharmacy is introduced including both client and server sides. Secondly, a solution to the high availability of this system is given in detail, including design and implementation. The essentiality of this solution consists of scope of system information, system parameter tables of service status, schedule strategies of load balance and how to acquire system parameters and detect service states. The solution proposed is scalable and application oriented and supporting load balance for high performance and fault tolerate for high reliability. This application system has been applied and verified realistically, and the features of this business system derived in this paper have been achieved.
