摘要:
An operation site has copy management information including state information that is used when executing a remote copy. The copy management information is stored in a storage device included in each of all storage device subsystems in this computer system. The copy management information is updated every time a remote copy is executed. When the operation site fails, by use of a copy management program in another operatable site, and with reference to the copy management information stored in the storage device of the storage device subsystem in each site, the copy is executed from a point to which the copy processing has progressed before the failure. As a result, when the production site in which an application is operated suffers from a disaster, it is possible to quickly recover data at the time of the disaster by executing a disaster recovery management program from another site in which no failure occurs, and then by restarting the remote copy.

Provided is a computer system, including: a computer; and a storage system coupled to the computer via a network. The computer includes: an interface coupled to the network, a processor coupled to the interface and a memory coupled to the processor. The storage system includes a plurality of volumes in which files are stored. The processor is configured to: decide duplicating files from among the files stored in the plurality of volumes as files to be consolidated; identify a plurality of volumes in which the files to be consolidated are stored; select at least one volume from among the identified plurality of volumes as a consolidation volume based on loads imposed on the identified plurality of volumes; and delete the files to be consolidated stored in the volumes that are not selected. Accordingly, in data de-duplication, it is possible to avoid extra loads from centralizing in a high-load-bearing volume.

The object of the present invention is to manage the use number relating to a user in a suitable manner, when a game device operated by a user downloads a file, such as a game program, or the like, from a file server, in order to play a game. Therefore, the present invention is a charge management server which stores use number data relating to a use number for a user, and a group of files for supply to the aforementioned user, performs authorization to permit or refuse connection on the basis of individual information relating to the user as transmitted by the game device operated by the user, receives a file transmission request sent by a game device having undergone the aforementioned authorization process, transmits a particular file as specified by the aforementioned file transmission request to the aforementioned game device, receives a confirmation message sent by said game device having completed reception of the aforementioned particular file, and updates the use number data of the aforementioned user.

A curling iron comprising a barrel rotatably supported on a grip portion and a clamping tongue which are assembled in a form similar to a pair of scissors so that the tongue makes pivotal movements relative to the barrel. The barrel, which is rotatable relative to the grip portion, encloses an electric heater in it and is designed to rotate in the direction opposite to the rotational direction of the grip portion of the curling iron by means of suitable gears provided between the barrel and the grip portion. The clamping tongue mounted onto the iron body may be formed with rollers arranged in arc form or with a plate bent in an arc. With such a structure, the hair held between the barrel and the tongue is curled from the root to the end by turning the grip portion which turns the barrel in the opposite direction of the handle turning direction by means of gears.

Proposed is an operation method for seeking a power interruption operation target in which MTBF will become longest. When a target value regarding a power interruption time and a target value regarding a power interruption count per 24 hours is input from an administrator to a management computer, the management computer calculates the MTBF after one year and the annual power consumption for each of the input target values, and, as a power interruption operation target in which the MTBF will become longest in one year, a target value regarding a power interruption time and a target value regarding a power interruption count are respectively selected among multiple target values in which the MTBF will become longest based on each of the calculation results, and displayed on a screen of an output unit.

A computer system having a plurality of operating systems and a module for switching the operating systems in view of priorities of tasks to be performed by each of the operating systems. Each of the operating systems performing a plurality of processes or threads in accordance with the priorities assigned to these processes or threads has a module for notifying the computer system of the priority of the currently executing process or thread. The computer system includes a module for translating the priorities sent from each operating system into priorities (normalized priorities) common-throughout the computer system, and a module for comparing the normalized priorities obtained by the priority translation module in order to select and execute preferentially the operating system having a common priority higher than that of any other operating system.

When there is a change in a group of volumes managed by a host computer, data duplication processing is immediately carried out against the changed volume. The host computer includes a volume-managing portion, a data duplication-controlling portion which executes the data duplication of data stored in a volume in a main data center, and a data duplication storing portion which stores data necessary for the data duplication. The data duplication-controlling portion compares data held by the volume-managing portion with the data in the data duplication storing portion, and updates the data in the data duplication storing portion based on the data held by the volume-managing portion.

A lock structure for a box includes a first box member having a retaining projection, and a second box member having an elastic retaining arm. The retaining arm has at its distal end a retaining portion for engagement with the retaining projection. The first box member has an arm restraint rib which restricts a releasing movement of the retaining arm in a condition in which the retaining arm and the retaining projection are engaged with each other. When the arm restraint rib is pressed by the elastic retaining arm, the arm restraint rib is deformed by a pressing force of the elastic retaining arm. A retaining distance of the retaining projection relative to the retaining portion of the elastic retaining arm is larger than a gap between the elastic retaining arm and the arm restraint rib in the engaged condition.
