摘要
从前兆区域台网对台网及节点子台前兆数据库使用维护的需要着手,系统分析前兆数据库使用中几类常见故障,给出应对解决方案,并详细介绍了区域台网数据库备份及故障后台站数据库数据恢复的方法。突破地震前兆数据库传统冷备份的局限,引入逻辑备份的方法,实现了数据信息库间传输,为提升台网数据库维护能力发挥了较好的作用。
Taking database maintenance for regional seismic precursory network and its sub-nodes as the perspective, this paper analyzed common malfunctions of the database, at the same time provid- ed solutions. Especially, they introduced sub-nodes database recovery solution which used another database as its backup. This paper broke traditional cold backup solution, and made information transmission between different databases came true by incorporating logical backup method, which made a good impression on database maintenance for regional seismic precursory network.
