| Abstract: | Hebei Province earthquake precursor database service system has been working continuously for 10 years, 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. |
