摘要
地震台节点前兆服务器是前兆台网技术系统的核心,它存储汇集了台站的监测数据,通过地震前兆台网数据管理系统实现与上下级的互联互通。主要介绍采用数据库冷备份方法将源服务器中观测的数据安全地迁移到目标服务器中,确保台站观测的数据免遭损失,以实现地震台前兆服务器更换升级,使前兆数据库继续正常运行。
Seismic precursor to node server is the core of the precursory network technology system, it stores the monitoring data of stations by through the earthquake precursory network connectivity of data management system and the supervisor. This paper mainly introduces the cold standby database method to the data observed from the source server migration to the target server safely, ensures the station observation data from loss of data in order to realize the seismic precursory server replacement upgrade, the precursor database can be continued to normal operate.
