Configure it to do so.

C. Industrial Application Field] The present invention relates to a remote automatic power control system in a wide area distributed system in which a plurality of computer systems are connected to a communication network via modems.

With recent advances in data communication technology via modems, in recent computer systems, multiple computer systems are installed in remote locations and communicate based on instructions from a centrally installed host computer system. Widely distributed systems are being constructed in which each computer system processes data in parallel while communicating data via a network.

For example, in the insurance industry, a central host computer system in Tokyo, for example, turns on the power to computer systems set up in rural areas of the country from the host computer system at night, etc. after finishing work on -day. Each system may be started up, and the results of insurance operations for that day stored in the file storage device of each computer system may be retrieved and management operations may be performed.

Such a widely distributed system requires a power supply control device that individually controls the power supply of each computer system according to instructions from a remote location.

However, since the wide-area distributed system as a whole becomes huge, the conventional method of controlling the power supply of the computer system at a remote location after the host computer system has started up increases the startup time of the entire wide-area distributed system. For example, a method has been adopted in which the host computer system is operated 24 hours a day to shorten the start-up time of the entire wide-area distributed system. Therefore, an effective automatic power control method that does not require 24-hour operation of the host computer system is needed.

[A problem to be solved by the prior art and the invention] Fig. 2 is a diagram explaining a conventional remote automatic power control system.
(a) shows an example of the system configuration, and (b) shows an operation time chart.

First, in the automatic power control device 4 connected to the host I/computer system 1, for example, when the time of the timer 43 reaches a preset power-on time, the automatic power control device 4 , starts the power control unit 41 and powers on the host computer system 1.

In the host computer system 1, after the initial program loading (IPL) is performed when the power is turned on, the operating system (O5) is started and the computer system 1 at the remote location is started up according to the operation content of the day. On the other hand, is the host computer system 1 on the line side? Device a (CCP) IL sends a power-on instruction message ■ via the communication network 3.

In the automatic power supply control device 4 connected to each computer system 1 at a remote location, when the line control unit 42 receives the power-on instruction message ■ from the modem 2, it starts the power supply control unit 41 and turns on the power supply. The computer system 1 directly connected to the control unit 41 is powered on.

When the power is turned on, the line control unit 42 of each automatic power supply control device 4 connects, for example, the line interface to the modem 2 and the line control device (CCP) of the computer system 1 connected to the automatic power supply control device 4. ) The line interface for the modem 11 is bypassed, and the modem 2 and the computer system 1 are directly connected.

In the computer system 1 at the remote location, after initial program loading (IPL) is performed, the operating system (O5) is started up and starts functioning as a widely distributed system.

That is, in the conventional remote automatic power control method, the automatic power control device 4 connected to the host computer system 1
Also, a power-on instruction message (■) is sent to the automatic power control device 4 connected to the communication network 3 via the modem 2 to the line control unit 42 that controls the line interface for each modem 2. It didn't have a mechanism.

The conventional method operates in this way, so when the scale of the wide-area distributed system increases, the time from the power-on start time of the host computer system 1 to each remote location increases as shown in the operation time chart in (b). Since it takes, for example, one hour or more for the computer system to start operating, there is a problem in that the availability of the widely distributed system is poor. In Figure (b), A: equipment power-on time;
B: System power-on time and C: lPL+OS startup time are shown, respectively.

Therefore, conventionally, the host computer system 1 is operated 24 hours a day, and the operating system (O3) starts from the time when the host computer system 1 is powered on.
), methods have been adopted to shorten the power-on time for the entire wide-area distributed system by eliminating the time it takes to start up the system.
This method has a problem in that the operating cost for operating the host computer system 24 hours a day increases.

In view of the above-mentioned conventional drawbacks, the present invention provides a wide area distributed system in which a plurality of computer systems are connected to a communication network via a modem.
It is an object of the present invention to provide a remote automatic power control method that can reduce the power-on time and economically improve the operating rate of the widely distributed system.

[Means to solve the problem]

The above problems are solved by a remote automatic power control system configured as follows.

In a widely distributed system in which multiple computer systems are connected to a communication network via modems, an automatic power control device attached to the computer system controls the power to the computer systems directly connected. a line control unit that sends and receives a power control instruction message ■ between the power control unit that performs the control and the line interface for the modem;
An automatic power supply connected to the host computer system, comprising a timer for instructing power control time and, if the computer system is a host computer system, an operation table for the wide area distributed system from the host computer system. The control device performs power control on the host computer system via its own power supply control unit based on the operation table at the time indicated by the timer, and controls the power supply to the host computer system through the power supply control unit specified by the operation table. A power control instruction message (■) is sent to the computer system at the remote location via the line control unit, and the automatic power control device at the remote location performs automatic power control connected to the host computer system. The power supply side fall instruction message ■ sent from the device is received by the own line control unit, the power supply control port is started, and the power supply control of the computer system directly connected to the power supply control unit is started. Performing step III, the host computer system and the remote computer system perform power control of all the computer systems that make up the widely distributed system in parallel.

[Effect]

That is, according to the present invention, in a widely distributed system in which a plurality of computer systems are connected to a communication network via modems, an automatic power supply control device connected to a host computer system, for example, At the power-on time, when the host computer system is powered on, the automatic power control device (A) connected to each computer system at a remote location is
RC) via the communication network to send a power-on instruction message ■ to the automatic power supply side of each remote location 'I21! When the device receives the power-on instruction message (■) at its own line control unit, - in parallel with the power-on of the host computer system,
By turning on the power to a computer system connected to its own automatic power supply control device, the entire wide-area distributed system can be started up in the time it takes to start up one host computer system. As a result, the power-on time required by a power-on instruction from a host computer system in a wide area distributed system is shortened, and the operating rate of the entire wide area distributed system is improved.
