US 5,291,613 A · Method for executing a control instruction in a multi-computer system

Abstract

In a multi-computer system in which a plurality of computers connected to each other through a transmission medium share a process to be carried out under relationships among a method performed by these computers executing a control instruction, characterized as; while the plurality of computers each have specific control instruction storage means for storing instructions having influence on normal operations of the multi-computer system, when any of the plurality of computers defects an input instruction corresponding to one stored in the specific control instruction storage means, determines the status of the shared process being carried out by other computers in connections to the self-computer, and uses the result of the determination in the execution of the detected control instruction.

In a multi-computer system in which a plurality of computers connected to each other through a transmission medium share a process to be carried out through at least two of said computers, a method for executing a computer control instruction, said method comprising the steps of:

inputting a control instruction to a first computer in said plurality of computers;
determining in said first computer whether or not said control instruction is to be executed by consulting a storage unit to determine whether an indication of said control instruction has been stored in advance, said specific control instruction having influence on normal operation of the system;
determining in said first computer the execution status of a process being performed in a second computer, when it is determined in the first determination step that said indication of the inputted control instruction is stored in said storage unit;
and
executing the inputted control instruction according to the execution status of said process as determined in the second determining step.
