ABSTRACT:
A computer system acquires mapping information of data storage regions in respective layers from a layer of DBMSs to a layer of storage subsystems, grasps correspondence between DB data and storage positions of each storage subsystem on the basis of the mapping information, decides a cache partitioning in each storage subsystem on the basis of the correspondence and sets the cache partitioning for each storage subsystem. When cache allocation in the DBMS or the storage subsystem needs to be changed, information for estimating the cache effect due to the change in cache allocation acquired by the DBMS is used for estimating the cache effect in the storage subsystem.
