Conventional distributed processing workstation systems are configured as described above, so if a program running on a service station cannot be started, a program that frequently accesses disks and inputs/outputs large amounts of data will be unable to work. If the program is executed on a service station, performance will deteriorate.Furthermore, if the workstation that can start the program executed on the service station is fixed, operations must be performed at the location where the workstation is installed, which reduces system operational efficiency. There was a problem in that the value decreased.

This invention has been made to eliminate the above-mentioned disadvantages, and allows programs to be executed on a service station at any time from any workstation or from multiple job partitions of a single workstation. The purpose is to obtain a distributed processing workstation system that can be started.

[The tth way to solve the problem]

The job control method according to the present invention is a distributed processing workstation system in which a service station job program to be executed at a service station is programmed from a workstation to a service station that does not have an input/output device such as a CRT display device or a keyboard. The name and parameters are entered all at once, the service station job program is scheduled in the service station job program, and the results are output to each workstation after execution is completed.

[Effect]

In the job control method according to the present invention, all service station job programs requested by workstations are scheduled on the service station, and can be sent from any coaxially connected workstation or from one workstation to another. A service station job program can be started from any job partition, eliminating operational problems arising from the actual facility environment.
