摘要
河北省地震前兆数据库服务系统故障率升高,硬盘存储空间不足,特别是地震台站节点无备份数据库,服务器一旦崩溃必然造成地震台站节点数据库中数据丢失。本文通过Oracle数据库EXP与IMP工具提供的导出/导入功能,完成由省地震局数据库到地震台站节点(崩溃)数据库的数据恢复,形成一套定期备份并恢复数据的方案,用于河北省地震前兆观测数据备份与恢复。
Hebei Province earthquake precursor database service system has been working continuously for10years,occurring higher failure rate and lack of hard disk storage space frequently.Especially in the station node backup database,data backup and recovery service is inevitable.In this paper,through the EXP and IMP tools of Oracle database which provide export/import function,the recovery of station node database from provincial earthquake agencey database are complemented.A scheme of data backup and data recovery at regular interval time has been applied to the Hebei Province earthquake precursory observation database
