The invention provides a method for the hot standby of dual database servers in the technical field of database systems. A system comprises an active database server and a standby database server. The two servers perform regular handshake, master-slave negotiation, data access and data synchronization through a synchronization network port. A server network port of the active database server employs a virtual Internet protocol (IP) address to externally provide server service, and a service network port of the standby database server does not externally provide database service. A database client accesses the active database server through the virtual IP address by adopting a transmission control protocol (TCP). A flexibly selectable real-time / quasi-real-time database synchronization mechanism, a comprehensive data consistency detection method for the active and standby database servers and a selectable data consistency recovery means are provided by the invention.

A data synchronization method is provided to enhance reliability and performance of the database. The data reflection method selection unit of the active server weights collected values in the resource utilization table by multiplying the collected values by assessment coefficients assigned to the individual collected values in an assessment coefficient table and sums up the weighted values to calculate an assessment value for each data reflection method, and determines the data reflection method whose assessment value is minimum. The log data transmission unit, according to the determined data reflection method, sends log data that is reflected on the active database to the standby server, which forms one of the duplicated servers making up the redundant configuration. The data reflection method identifies the content to be transmitted.
