Abstract

PURPOSE:To secure a high-speed process for alteration of the common data by storing the common data to be altered into the memory of the CPU for each host in the form corresponding to the storage address of the external memory. CONSTITUTION:When the common data in external memory 1 is altered in the outpatient clinic, the host in the clinic in forms all other hosts that the common data alteration phase is given and also transmits the common data to be altered. Each host which receives the common data stores the data to be altered into the common data alteration area, and then stores the address of the corresponding external memory in the form of the track, sector and word counter each thus to set the flag under alteration of the common data. After this, the host in the outpatient clinic knows that all hosts have finished the alteration phase of the common data and then informas this to all hosts. Then all hosts write the alteration data in the memory into the external memory at their leisure to clear the flag.
