  As a disaster countermeasure in a computer system, there is a computer system recovery method by cold standby. In the current cold standby, the failure of the active system is detected and then the standby system is transferred to the active system. Therefore, the active system may be destroyed before the completion of the migration work. The period during which the system is not operating may become longer.

  On the other hand, as a disaster countermeasure different from the above, there is a computer recovery method by hot standby. In the current hot standby system, the transition from the standby system to the active system only requires the migration of the program and the data used by the program, so the migration time is short, but the computer of the standby system is always in operation. Power.

  In the present invention, the emergency disaster warning receiving device accepts an emergency disaster warning including the emergency earthquake warning in the earthquake warning system, and forwards the emergency disaster information to both the active and standby computer systems before the disaster occurs, thereby cold standby. The purpose of this is to reduce the time required to shift a faulty active system to a standby system while maintaining the low power cost advantage of the system.

  In order to solve the above problem, according to the present invention, an emergency disaster warning receiving device on a network under jurisdiction receives means for receiving an emergency disaster warning in a natural disaster or a human disaster including an emergency earthquake warning, and the emergency disaster warning. Based on the disaster information contained in the network, the received emergency disaster warning data is transferred to one or more active computers on the network, or transferred to a data format that can be received by the disaster response program on the computer. Based on the disaster information included in the means and the emergency disaster warning, one or more non-working computers on the network are transmitted with a signal instructing a boot command, and one or more activated Transfer the received emergency disaster warning data to the computer or convert it into a data format that can be received by the disaster response program on the computer Between the emergency disaster alarm receiving device existing in the disaster area and the emergency disaster alarm receiving device existing in the non-disaster area when the emergency disaster alarm received in the disaster area is not delivered to the non-disaster area Thus, emergency disaster warning data is transmitted and received.

  In the present invention, the standby system is in operation when receiving an emergency disaster warning distributed when a disaster occurs in the active system, so that the system can be switched at high speed at the same power cost as the current cold standby. it can.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The non-operating computer 202 arranged in the non-disaster area network 200 includes one or more computers, and is connected to the non-disaster area network 200 via a wired or wireless network.

  One or more emergency disaster alarms 300 including a disaster warning of a natural disaster alarm 301 related to a natural disaster or a human disaster alarm 303 related to a human disaster are arranged in the disaster area network 100, or The emergency disaster warning receiver of the emergency disaster warning receiver 201 arranged in the disaster area network 200 receives the information.

  The emergency disaster alarm 300 includes only the emergency disaster alarm receiver 101 arranged in the non-disaster area network 200 or the emergency disaster alarm receiver 101 arranged in the disaster area network 100 and the emergency arranged in the non-disaster area network 200. Simultaneously distributed to the disaster warning receiver 201.

  When the emergency disaster warning 300 is simultaneously distributed to the emergency disaster warning receiving device 101 arranged in the disaster area network 100 and the emergency disaster warning receiving device 201 arranged in the non-disaster area network 200, it is arranged in the disaster area network 100. The emergency disaster alarm receiving apparatus 101 analyzes the received emergency disaster alarm 300 and determines whether or not the data format is receivable by the operating computer 102 arranged in the disaster area network on the disaster area network 100. When the data format is receivable, the emergency disaster alarm 300 is transferred to the operating computer 102. In the case of a data format that cannot be received, the emergency disaster alarm 300 is transferred to the operating computer 102 arranged in the disaster area network 100 after conversion to a receivable data format.

  The emergency disaster warning receiving device 201 arranged in the non-disaster area network 200 analyzes the received emergency disaster alarm 300, and then, with respect to the non-operational computer 202 arranged in the non-disaster area network 200 on the non-disaster area network 200, Send a start command. After the non-operating computer 202 arranged in the non-disaster area network 200 is activated, it is determined whether or not the non-operating computer 202 arranged in the non-disaster area network 200 has a data format that can be received. In the case of a receivable data format, the emergency disaster alarm 300 is transferred to the non-operating computer 202 arranged in the activated non-disaster area network 200. In the case of a data format that cannot be received, the emergency disaster alarm 300 is transferred to the non-operating computer 202 arranged in the activated non-disaster area network 200 after conversion to a receivable data format.

  When the emergency disaster warning 300 is distributed only to the emergency disaster warning receiving device 101 arranged in the disaster area network 100, the emergency disaster warning receiving device 101 arranged in the disaster area network 100 is arranged in the non-disaster area network 200. The emergency disaster warning 300 or the data-converted emergency disaster warning 300 is transferred to the emergency disaster warning receiver 201.

  FIG. 2 is a flowchart illustrating in detail the procedures of the emergency disaster warning receiving apparatus 101 arranged in the disaster area network 100 and the emergency disaster warning receiving apparatus 201 arranged in the non-disaster area network 200.

  In FIG. 2, 400 is an emergency disaster alarm reception block for receiving an emergency disaster alarm, 401 is an emergency disaster alarm analysis block for analyzing data of the received emergency disaster alarm, and 402 is a jurisdiction network determination block for determining a network under jurisdiction. 403, an activation command transmission block for transmitting an activation command to a computer on the jurisdiction network; 404, an emergency disaster alarm determination block for determining whether the received emergency disaster alarm can be received by a computer on the jurisdiction network; and 405, a computer. Is an emergency disaster alarm conversion block for converting an emergency disaster alarm into a data format that can be received, 406 is an emergency disaster alarm transfer necessity determination block for determining whether to transfer an emergency disaster alarm to the non-disaster area network 200, and 407 is Connect to a computer on the jurisdiction network Emergency disaster warning computer for transfer block for transferring the disaster warning, 408 denotes an emergency disaster warning receiver apparatus for transferring blocks of transferring emergency disaster warning to the emergency disaster warning receiver device 201 of the non-affected area network 200.

  In the emergency disaster alarm reception block 400, the emergency disaster alarm 300 is received from the transmission base of the emergency disaster alarm 300 connected by a wired or wireless network. The emergency disaster warning analysis block 401 analyzes the emergency disaster warning 300. In the emergency disaster warning analysis block 401, the magnitude of an assumed disaster or the magnitude of an actual disaster, an assumed disaster occurrence location or an actual disaster occurrence location, an expected disaster included in the emergency disaster warning 300 Or the actual disaster type (collectively, this information is referred to as “disaster information included in the emergency disaster warning”), and when the standard value set in advance in this device is satisfied, Control for executing the processing after the network judgment block 402 under the jurisdiction of the emergency disaster warning device is also performed.

  In the jurisdiction network determination block 402, the network under the jurisdiction of this apparatus is determined. If the disaster area network 100 is “Yes”, the process proceeds to the emergency disaster alarm determination block 404. If it is the non-disaster area network 200 (in the case of “No”), the activation command is transmitted to the non-operating computer 202 arranged in the non-disaster area network 200 under the control of the activation command transmission block 403. After confirming that the number of computers corresponding to the number of operating computers specified in advance is activated, the process proceeds to the emergency disaster warning determination block 404.

  In the emergency disaster warning determination block 404, it is determined whether or not the emergency disaster warning 300 is in a data format that can be received by a computer under its control. If the data format cannot be received (in the case of “impossible”), the emergency disaster warning conversion block 405 converts the data format into a data format that can be received by the computer. For example, in the case of a computer that receives the earthquake early warning 302 but cannot receive a human disaster warning, prepare a common data format that can be received by the computer in advance, and transfer the emergency disaster warning 300 after converting it to the common data format. I do. Alternatively, as an option when there is no alarm that can be received on the computer, there is an option in which only the activation notification is performed and the emergency disaster alarm 300 is not transferred.

  When the data format is receivable (when “possible”), the process proceeds to the emergency disaster warning transfer necessity determination block 406.

  In the emergency disaster alarm transfer necessity determination block 406, it is found that the emergency disaster alarm 300 is not delivered simultaneously to the non-stricken area network 200 in advance by the apparatus that has been placed on the disaster area network 100 and has received the emergency disaster alarm 300. If it is ("necessary"), as seen in the emergency disaster alarm receiver transfer block 408, the emergency disaster alarm 300 or the emergency disaster alarm 300 arranged in the non-disaster area network 200, The converted emergency disaster alarm 300 is transferred.

  Further, when it is not known that the emergency disaster alarm 300 is not distributed simultaneously on the non-disaster area network 200 (in the case of “unnecessary”), the emergency disaster alarm computer transfer block 407 transmits to the computer on the network in charge. The emergency disaster alarm 300 or the converted emergency disaster alarm 300 is transferred.

  As described above, when the emergency disaster warning receiver is arranged on the disaster area network 100 and the non-stricken area network 200 and the emergency disaster warning receiver receives an emergency disaster warning such as an emergency earthquake warning, High-speed system switching can be performed by transmitting a startup command from the emergency disaster warning receiver 201 on the disaster area network 200 to the non-startup computer 202, starting the computer, and transmitting an emergency disaster warning (from cold standby) Fast transition to hot standby).
