ABSTRACT:
A Database Management System (DBMS) of a main host system is directed by its agent to overwrite database table data (DB table data), which is stored in a DB buffer and put in and out by the DBMS, to the database table (DB table) on a main disk unit, and holds the updating of the DB table data in the DB table against a subsequent request of updating. A main disk control unit is directed by the agent to transfer the DB table data in the DB table to a DB table on a subordinate disk unit by a subordinate disk control unit to duplicate the DB table data, and suspend the subsequent transfer of DB table data so that the DB table data on both disk units are in a state of matching, thereby enabling the DBMS of the subordinate host system to refer to the copied DB table.
