Abstract
Provided is a database management system (DBMS). The DBMS synchronizes an active node with a standby node and detects a point of time when last synchronization is performed between the active node and the standby node. Then, after the DBMS performs page synchronization from the detected point of time of the last synchronization to a point at which a failover occurs in the active node, the DBMS performs partial log synchronization by receiving a log from the standby node after the point of time of the last synchronization until the active node is recovered.
