A device for managing a database in a dual processor and a controlling method thereof are provided to maximize operation stability of a dual system by making an active processor check a state of replication between the active and standby processor, and updating database data to a standby side in case of a normal state. The dual processor respectively includes an application block(3A,3B) and a database server(5A,5B). The application block calls/processes a needed database task by inputting the active processor to a function parameter of a database library to perform the needed database task according to an application request of a manger terminal(2). The database server processes the data stored in the database(4A,4B) by only the active processor according to a database task request signal of the application block and transmits/updates the processed database data to the standby side through the replication in case that the replication is normally operated.
