[0003]

Conventionally, software development has been carried out on a large-scale computer, but with the downsizing and cost reduction of computers, a network connecting a plurality of small-scale computers has been used, and each computer has been developed. It tends to be distributed over. However, the above-described conventional multi-process cooperative method relates to the cooperative operation of multiple processes in one computer, and the cooperative operation of multiple processes in multiple computers when using a computer network has not been considered.

The present invention has been made to solve such a problem, and enables communication between computers of execution results of processes executed on a plurality of computers in a computer system, thereby enabling communication between other computers. It is an object of the present invention to provide a multi-process cooperation method and a computer system in which an operator can know the execution result of a related process, and can know the result even if the processes are not simultaneously executing.

[0005]

According to a method for coordinating a plurality of processes of the present invention, in a computer system in which a plurality of computers are connected for data communication, the execution result of a process executed by one computer is related to the execution result. Is transmitted to another computer that is executing the process, and is transmitted to another computer that executes the process related to the execution result when the process is started.

The computer system of the present invention is a computer system in which a plurality of computers are connected for data communication so that data communication between the computers is performed based on the process executed by each computer. Execution process holding means for holding information indicating the result, result holding means for holding information indicating the result of the executed process, reference information holding for holding information indicating whether the execution result of the process is transmitted to another process Means and means for searching the reference information holding means at the time of starting the process, checking whether or not the execution result of the other process related to the process is transmitted to the process, and transmitting the execution result to the process if the result is not transmitted. When,
When a process execution result is obtained, another process related to the process execution result is searched, and means for transmitting the process execution result to the process being executed among them is provided.

[0007]

When the process is started, information indicating the process is held in the running process holding unit. On the other hand, the reference information holding means is searched and it is checked whether or not the execution result of the other process related to the started process is transmitted to the started process. Take out and send to the started process. When the execution result is to be displayed by the normal language message on the display of the computer related to the activated process, the operator of the activation process can easily know the execution result of the other process.

When the execution result of the process is obtained, the end of the process is notified to the in-execution process holding means and held. Further, the execution result is held in the result holding means. Then, another process related to this execution result is searched, and the execution result is transmitted to the process being executed. By displaying this in the ordinary language on the display of the computer of the receiving side process as in the case described above, the operator can easily know the execution result of the other process in real time. For the process that is not transmitted because it is not being executed, it is held in the reference information holding means, and the execution result is received when the process is started as described above.
