摘要： A database management system (DBMS) manages a database existing in a second storage device with an access speed lower than that of a first storage device. In an execution of a query, the DBMS dynamically generates tasks two or more executable tasks in parallel. The DBMS generates task start information which is information representing a content of the execution of the task, manages the task start information, and executes a content represented by the task start information by the task. The task start information includes a data address set existing in the second storage device. The DBMS controls movement of the data address sets between the first storage device and the second storage device based on a management state of the task start information. In addition, the DBMS selects the task start information based on whether or not the data address set exists in the first storage device.

摘要： A computer is used in a computer system including multiple physical storage areas for storing database data. The database includes component information having a reference item having plural value ranges. The database data is dividable according to value ranges of the reference item. The computer comprises an access frequency obtaining module and a data allocation module. The access frequency obtaining module obtains, for each value range of the reference item in the component information, an estimated access frequency for data of the component information. The data allocation module allocates, based on the obtained estimated access frequency, data of the component information divided according to the value ranges of the reference item to the physical storage areas to be stored.

摘要： 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.

摘要： A computer system identifies jobs affected by a fault which occurs in any device or mechanism in a storage system to control the execution of such jobs. The computer system includes a DBMS server device, a virtualization switch device, and storage device. Each of these devices holds part of data mapping information on a data mapping path from a particular DB table accessed by a job, through a logical volume for storing the table, to physical disk units for distributively storing data on the volume. The management server device acquires the part of data mapping information from each device, and integrates the data mapping information on a job-by-job basis. When any device or mechanism fails on the data mapping path, the management server device identifies jobs affected by the fault with reference to the data mapping information. The management server device also controls the execution of these jobs.

摘要： A diversity receiver has distributors each of which is connected with each of a plurality of antennas, and as many antenna switches as there are receivers. Each of the antenna switches has as many contacts as there are distributors. The distributor distributes a radio frequency signal from the antenna into as many signal paths as there are receivers. Each of the antenna switches is connected with each of the distributors via the contact connected with the signal path. A demodulated signal selecting circuit has as many contacts as there are said receivers. The demodulated signal selecting circuit receives the demodulated output of the receivers via each of said second contacts to selectively output the demodulated outputs of the receivers.

摘要： A database management system (DBMS) generates a query execution plan including information representing one or more database (DB) operations necessary for executing a query, and executes the query in accordance with the query execution plan. In the execution of the query, the DBMS dynamically generates tasks for executing the DB operations and executes the dynamically generated tasks. The query execution plan includes a plurality of query blocks, which are sets of one or more DB operations. When newly generating a task, the DBMS executes determination processing of simultaneous-task-generation number. The determination processing of simultaneous-task-generation number is to calculate, targeting each of the query blocks, the number of simultaneous task generation, which is the number of tasks simultaneously generatable as tasks for executing the query block. The number of the dynamically generated tasks is equal to or smaller than the number of simultaneous task generation.
