摘要:
A data processing system for allocating a plurality of peripheral storages to a plurality of users comprises a data processing device, a plurality of peripheral storages connected with the data processing device, a catalog control unit for setting on a table a total usage capacity of the usable space set by users including an active pool having a plurality of peripheral storages to which files are allocated and an inactive pool for holding files which are migrated from the active pool, a file allocating unit which sets the current usage capacity on a table depending upon the use of space of said active pool to compare the sum of the added space capacity inputted by users and the current usage capacity with said total usage capacity for deciding an error of allocation of the added peripheral storage when the sum is larger than the latter. A part of the peripheral storage in the active pool is set as spare volumes and the spare volumes are temporarily allocated when a failure occurs in the remaining part of the peripheral storages in the active pool or when there is not enough free space in the active pool.

A cache mode selection method and system sets to a cache load inhibit mode a cache mode used for a random access dataset of lower access hit ratio if use ratio of a data transmission path exceeds beyond an upper use ratio limit. It also sets to the cache load inhibit mode the cache mode used by parts of a sequential access dataset. These make it possible to select a proper cache mode depending on state of a load dynamically to prevent an I/O response from decreasing so that the hit ratio can be increased.
摘要:
A pair of piezoelectric substrates, the length of which is shorter than the length of one side in the longitudinal direction of the operation panel or the supporting board, is respectively fixed to one side from the diagonal position along the longitudinal direction. At the time of detecting an inputting operation, a drive voltage is applied and the entire operation panel or the supporting board is vibrated. Even when the four corners of the operation panel or the supporting board are supported by the housing for accommodating the tablet apparatus or supported by the display device so that the vibration of the four corners is restricted, since either of the pair of piezoelectric substrates, which becomes a vibration source, a feeling of inputting operation can be transmitted to an operator by the vibration, the amplitude of which is not less than a predetermined value, irrespective of the inputting operation position.

In a multi-computer system having a plurality of computers, an input/output device configuration definition table and an input/output device configuration reference table are adapted to be collectively managed. A configuration management program manages the configuration definition of all input/output devices of a plurality of computers by using the input/output device configuration definition table, and generates a changed data file when an input/output device configuration is changed. Dynamic system alteration is effected by changing the contents of the input/output device configuration reference table stored in a shared memory, in accordance with the changed data file. The input/output device configuration definition table and the input/output device configuration reference table each have an input/output device information part and an input/output device connection information part arranged in a matrix form to allow addition/deletion of an input/output device and a computer.
摘要:
A method of controlling data which is stored into a common storage in a multiprocessor system having a common storage which can be accessed from a plurality of computers is disclosed. Particularly, a method of controlling shared data using an extended storage as a common storage is disclosed. The copy of the data of a part of or all of a shared data set in an input/output device and the copy data control information to control the copied data are stored into the common extended storage. In the case of accessing the data in the common extended storage, the mutual exclusion among a plurality of computers and the consistency control of the data are realized by referring to the control information stored in the common extended storage.

摘要:
A holding structure for a touch panel has a display panel for configuring a display screen and a touch panel for allowing input operation. The structure has an elastic supporting frame for holding the display panel at an entire peripheral edge and supporting the touch panel in parallel with the display panel. The structure has piezoelectric devices for applying vibration to the touch panel in accordance with the operation of the touch panel. The structure has a casing for holding the display panel and the touch panel by way of the elastic supporting frame and the casing has an opening through which the touch panel is exposed. The elastic supporting frame holds the touch panel at an entire peripheral edge of the touch panel and includes a plurality of touch panel supporting portions for supporting the touch panel at a side edge of a rear surface of the touch panel.
