The only way to improve these problems is to rely on the user's program, which results in the user's program becoming more complex, the amount of development man-hours required, and the amount of dedicated memory required. Furthermore, since the user program functions under the operating system, it has the disadvantage that satisfactory results cannot be obtained due to functional limitations of the user program, such as the inability to log keyboard data on the operating system. Ta.

As a result, even if a distributed information processing system could be constructed, major problems remained regarding the subsequent operation and maintenance of the system.

The present invention has been made in view of the above-mentioned conventional circumstances, and
An object of the present invention is to enable monitoring of the operational status and operation history of multiple jobs executed within each station from any station, in order to solve new problems related to system operation and maintenance caused by distributed processing. An object of the present invention is to provide a remote operation management method for a multi-station information processing system in which a job such as a recovery program can be submitted from any station.

[Means to solve the problem]

A remote operation management method for a multi-station information processing system according to the present invention connects a plurality of information processing equipment stations via communication lines, and allows each station to share input/output devices connected to each of the information processing equipment stations. Each of the information processing device stations in the multi-station information processing system includes a job monitor unit that stores job execution status, a keyboard log memory unit that collects and stores keyboard input data, and the job monitor and keyboard log memory unit. a job execution state management unit that manages the job execution status;
