    Abstract: A database management system (DBMS) generates a query execution plan including information indicating one or more database (DB) operations necessary to execute the query. The DBMS dynamically generates a task for executing the DB operation in execution of the query. The DBMS performs a determination processing of simultaneous-task-generation number when newly creating a task. The determination processing of simultaneous-task-generation number is to calculate the number of simultaneous task generation, which is the number of tasks that can be generated simultaneously, based on the number of tasks which can be newly generated, a first memory resource amount which is the amount of memory resources necessary to be allocated per task newly generated, and a second memory resource amount which is the number of memory resources that can be newly allocated. The number of tasks generated dynamically and simultaneously is equal to or smaller than the calculated number of simultaneously generatable tasks.

    Abstract translation: 数据库管理系统（DBMS）生成查询执行计划，其包括指示执行查询所必需的一个或多个数据库（DB）操作的信息。 DBMS在执行查询时动态生成执行DB操作的任务。 当新创建任务时，DBMS执行同时任务生成次数的确定处理。 同时任务生成号的确定处理是基于可以新生成的任务的数量来计算同时任务生成的次数，即同时生成的任务的数量，第一存储器资源量 是每个新生成的任务需要分配的内存资源量，以及作为新分配的存储器资源的数量的第二存储器资源量。 动态和同时生成的任务数量等于或小于计算出的同时可生成任务的数量。

    Abstract: A disk rotation control part for controlling the rotations of a plurality of disk devices is provided. The configuration is such that a disk of a disk device for which an access will not be generated is rotated at a second rate of speed, which is faster than 0, and slower than a first rate of speed, which is the rotation speed at access time. DB management information comprises information denoting which DB schema inside a DB is stored in which location. The disk rotation control part, based on a query plan of a query received by the DBMS, and DB management information, specifies the storage location of a DB schema to be accessed when this query is processed, and rotates a disk of the disk device comprising the specified storage location at a first rate of speed.

    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.

    Abstract: In a system in which a DB is built in a virtualization environment, a management server obtains DB processing information such as a DB processing execution plan and a degree of processing priority from a DBMS, predicts data to be accessed in the near future and the order of such accesses based on the information, instructs to read into caches of storage devices data to be accessed in the near future based on the prediction results, and reads the data that will be accessed in the nearest future into a cache memory within the management server.
