    摘要: According to the present invention, a file recovery system is provided in which the commands for recovering files such as a historical file are unnecessitated and the recovery system configuration is independent of the host processing system. That is, since the equipment for achieving a file recovery does not have information about the location of the recovery data, information about the content of a file to be recovered is transmitted to a transmission line. The other equipments asynchronously receive the information and judges whether or not a file containing the same content exists in the own system. If its file exists, the content of the file is transmitted to the transmission line. The equipment achieving the file recovery asynchronously receives from the transmission line the file data of files such as a historical file and establishes data consistency by use of the buffered current data and the event number, thereby recovering files such as a historical file.

    摘要: Several processors and several communication control units are connected to a transmission medium. Each communication control unit has one or more terminal devices connected to it, and so any terminal device can be coupled to any processor. Each processor includes a central processing unit, a memory, and a control manager. The memory stores first information regarding processing being done with a terminal device coupled to the processor and second information regarding the communication control units connected to each of the processors and regarding the terminal devices being serviced by the processor. The control manager manages the communication control units based on the stored information. Information about the connections between the processors and the communication control units is broadcast to all processors. If any processor is faulty, another processor can take over the processing being done by the faulty processor. Likewise, further, processors can be added to the network, and their connection status is known to all other processors.

    摘要: In a distributed processing system wherein a plurality of processors are connected through a network and wherein programs are transmitted among the processors; each of the processors monitors the status of a program in the processor or the load status of any other of the processors as indicated by a message on the network. Upon performance of a judgement operator, the processor broadcasts a message indicative of the status of the processor or a program with a content indicating code affixed thereto, to another network, and the processor having received the message broadcasts a program existent in the other processor to the network along with the code indicative of the content of the program. The broadcast is performed in the other processor in accordance with the load statuses of the processors, and upon judging the content of the received message. Each processor judges whether or not the program being broadcast corresponds to a function necessary for a process of the processor based on the code indicative of the content of the program. If the program is needed, the processor loads and executes the program.
