基于集群的关键业务软件高可用性技术

High Availability Technology Based on Cluster in Important Service Software

基于微软的Windows集群系统,可在业务软件内部实现对其应用层的检测。当发生错误时,能及时捕获并保存业务应用程序的系统状态和业务环境信息。通过集群API接口函数控制集群实现错误转移后,基于XML文件日志记录方式对业务软件进行系统状态回滚与应用环境重建,达到关键业务软件在业务应用级的高可用性要求。

The Windows cluster system based on Microsoft could realize its application detection in mission software. When error existed, the system could capture and store the system status and mission environment information of mission application program, The cluster API interface function was used to control cluster and realize the error transformation. Based on XML document log record manner, the system status rolling back and application environment reconstruction was realized for mission software. Then, the key mission software achieved the high availability needs in mission application level.
