Abstract

PURPOSE:To interrupt a program during the execution of a program loading by providing a means which recognizes an interruption request during the execution of program loading. CONSTITUTION:When the job step interruption request is inputted from a console 1, a job step state discriminating means 2 discriminates whether the job step is program loading or not by a job step state storage part 4. When it is program loading, a program load end requesting means 3 instructs the storage part 4 to end the program load processing. A program load end recognizing means 8 refers to the storage part 4 to discriminate whether end of program load processing is requested or not, and when it is requested, the program load processing is ended by a program load ending means 11. Thus, the job step is interrupted in the stage of program loading.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for interrupting job steps, and particularly to a method for interrupting job steps during program loading.

[Conventional technology]

In conventional computer systems, even if a request to interrupt a job step is made, if the job step is in the program load stage, the job step cannot be interrupted until the program load is completed.

[Problem that the invention seeks to solve]

In the conventional computer system described above, a request to interrupt a job step at the program loading stage is delayed until the program load is completed, so it takes a considerable amount of time to interrupt a job step. Therefore, in a system that uses large programs, this delay time has a considerable effect when all programs are interrupted and stopped.

The problem to be solved by the present invention, in other words, the purpose of the present invention is to provide a method for interrupting a job step when loading a program, which improves the above-mentioned drawbacks by recognizing an interrupt request while executing a program load. There is a particular thing.

[Means for solving problems]

The job step interruption method when loading a program according to the present invention is such that if no interruption request is made to the job step,
job step state determination means for determining whether or not the job step is in the program load stage, based on a job step state storage unit that sets the job step state; program load abort request means set in a storage unit; program load abort recognition unit that recognizes a program load abort request from the job step state storage unit each time program data is read during program loading for the job step; program load abort means for loading the read program data into a virtual storage space when the program load abort request is not recognized by the means, and aborts loading of the program when the program load abort request is recognized by the recognition means; The present invention is realized by having a job step interruptible means for making the job step interruptible after being aborted by the aborting means, and a means for interrupting the job step that has become interruptible by the aborting means.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the same figure, a job step interruption method 100 during program loading includes a console 1, a job step state determining means 2, a program load interruption requesting means 3, a job step state storage section 4, and a program load waiting queue 5.
, program load reception means 6, program information reading means 7, program load abort recognition means 8, virtual storage space creation means 9, program load completion means 10, program load abort means 11, job It is composed of a step interrupting means 12, a job step interrupting means 13, and a program storage file 14.

Next, the operation of this embodiment will be explained. console 1
In response to the job step interrupt request submitted by the job step interrupt requester 2, the job step state determining means 2 uses the job step state storage section 4 to determine whether or not the job step interrupt is in the process of program loading. If the program is being loaded, the program load abort requesting means 3 instructs the job step status storage unit 4 to request abort program load in order to request abort of the program load process for the job step. On the other hand, the program load reception means 6 selects a job step from the program load waiting queue 5 and changes the job step state storage section 4 to the program load state. The program information reading means 7 reads program data corresponding to the job step selected by the program load receiving means 6 from the program storage file 14. Each time the program data is read by the program information reading means 7, the program load abort recognition means 8 refers to the job step status storage section 4 and determines whether there is an abort request.

If the program load abort recognition means 8 determines that there is no program load abort request -6=, the program information read by the program information reading means 7 is stored in the virtual memory space by the virtual memory space creation means 9, and the program is re-programmed. Return to information reading means 7. When the program load abort recognition means 8 determines that there is a program load abort request, the program load abort means 11 aborts the program load process. Then, the job step interrupting means 12 makes preparations for interrupting the job step, such as initializing the virtual storage space, and further, the job step interrupting means 13 interrupts the job step, such as saving the job step information file. Processing takes place.

On the other hand, when all program data information has been created in the virtual storage space, the program load completion means 10 changes the job step state storage unit 4 to the program load completion state.

〔Effect of the invention〕

As explained above, the present invention incorporates a trigger for determining a job step interruption request into the program loading stage, thereby making it possible to interrupt the job step before the program loading is completed, thereby improving operability during program loading. , it has the effect of being able to interrupt the system regardless of the execution status of a large program.
