Abstract:

     The essentiality of disaster recovery for consecutive operation w as introduced .Several methods of disaster recovery , main principles and design schemes were given.Through analyzing the logic structure of short message platform of personal access phone system (PHS), functional request for disaster recovery system was put forward.According to functional request for disaster recovery system , the logic structure of disaster recovery system was determined.The test data package w as designed to verify whether is the system malfunctions.To test the data changes of different members in data package decided net situation among cur rent functional modules and between functional modules and monitor modules , and work situation of all function modules.The data change rules to arise breakdown were given .In terms of rules , switch condition between the main module and the backup module was set .While a breakdown that the system can get rid of automatically appears , the system provides a sound alarm and the breakdown is eliminated automatically .When a breakdown that the system cannot fix appears, the system informs the administrator by a shor t message or E-mail to restart the system

摘要:      介绍了灾难恢复对于连续性业务的必要性, 给出现有的几种灾难恢复方法及部分方法的主要原理和设计方案。通过分析小灵通短信平台的业务逻辑结构, 提出对灾难恢复系统的功能要求。根据灾难恢复系统的功能要求确定灾难恢复系统的逻辑结构。设计了验证是否出现故障的测试数据包。通过测试数据包中不同成员数据的变化确定当前的功能模块间及功能模块与监控模块间的网络状态和各功能模块的工作状态。给出判断出现故障的数据变化规则。根据规则确定主模块与热备模块间的切换条件。当出现可自动排除的故障时, 通过声音报警给出提示, 并自动排除故障。当出现不可自动恢复的故障时, 通过手机短信或者E -mail 通知系统管理员人工重新启动系统。
