信息系统在线状态检修部署架构研究

为实现信息系统在线状态检修，减少系统检修时长，增强系统对外业务应用连续性，安徽省电力公司与中间件和负载均衡器技术支持厂商合作，以现有核心信息系统为研究对象，通过数个月的研究和试验，最终完成信息系统在线状态检修部署架构的可行性论证，并成功摸索出一套行之有效的信息系统在线状态检修部署架构适用性通用测试方法。目前该架构在安徽省电力公司应用效果良好，已完成对多套信息系统的改造，增强了系统检修的灵活度，提升了系统运行管理水平。

Exploration of Information System Online Maintenance Deployment Architecture

In order to realize online maintenance, reduce the maintenance duration time and enhance the business continuity for information systems, Anhui electric power company cooperates with several technology vendor supports of rniddleware and Ioad-balancer, and completes the feasibility study of information system online maintenance deployment architecture by doing researches and experiments on the existing core information systems for many months. Meanwhile, a feasible set of common testing methods for the deployment architecture test is successfully built. Application of the deployment architecture to the upgrade of a few information systems in Anhui electric power company show that the effect is good. The proposed deployment architecture can improve the flexibility of system maintenance as well as the level of system operation management.
