Abstract

PURPOSE:To enable a computer system to flexibly deal with the change of the state of a started job by keeping a user program in a waiting state until the state of the started job is coincident with the waiting conditions and executing again the user program when the waiting conditions are satisfied. CONSTITUTION:A job starting process part 1 requests the application of a job and stores the waiting conditions into a waiting condition memory part 2 to deliver the control to a job waiting process. Thus an on-line program is temporarily stopped. A job execution process part 4 executes a job after receiving an executing request from part 1. Then a started job state informing process part 6 informs a waiting condition deciding process part 5 of the job state every time the state of the job under execution changes. Thus the program can be set in a waiting state in response to the state change of the job that is dynamically started by the program. At the same time, the synchronization is attained with high flexibility.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an activated job waiting method for re-executing a suspended user program by monitoring and notifying the status of activated jobs in a computer system.

(Prior Art) In a conventional computer system, when a started job is finished and a completion notification is received, the suspended user program is re-executed. It's in sync. Therefore, a stopped user program cannot be started until the startup job is completed.

(Problem to be solved by the invention) In the conventional method described above, the user program cannot be re-executed until the user program receives the completion notification after waiting for the end of the started job.For this reason,
This method has a disadvantage in that there is no flexibility in how to synchronize the user program that sent the request to start a job and the job that has been started.

An object of the present invention is to dynamically start a job from a user program, register waiting conditions for the user program to synchronize with the started job, and store the waiting conditions. The above disadvantages are eliminated by keeping the user program in a waiting state until the above waiting condition is met, and starting re-execution when the waiting condition is met, allowing the computer system to flexibly respond to changes in the state of the startup jib. The object of the present invention is to provide a startup job queuing method configured to enable the following.

(Means for Solving the Problems) A job queuing method according to the present invention includes a job starting processing means, a queuing condition registration processing means, a queuing condition storage means,
The apparatus includes a job queuing processing means, a job starting processing means, a job status notification processing means, a queuing condition determination processing means, and a queuing job re-execution notification means.

The job starting processing means is for dynamically starting a job from a user program.

The waiting condition registration processing means is for registering the waiting conditions necessary for synchronizing the user program and the activated job.

The meeting condition storage means is for storing meeting conditions.

The job queuing processing means is for, after starting a job, matching the user program Ki until the status of the started job matches a queuing condition, and starting re-execution when the queuing condition is met.

The job activation processing means is for executing a job activated from a user program.

The job status notification processing means is for notifying the status of the activated job.

The waiting condition determination processing means receives a status notification from the activated job and determines whether or not the waiting condition stored in the waiting condition storage means matches the status of the activated job.

The waiting job re-execution notification means is for notifying re-execution to the waiting user program when the state of the activated job matches the waiting condition.

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

FIG. 1 is a block diagram showing one embodiment of a start-up jib queuing method according to the present invention. 4 In FIG. 1, 1 is a job activation processing section, 2 is a waiting condition storage section, 3 is a waiting condition registration processing section, 4 is a job execution processing section, 5 is a waiting condition judgment processing section, and 6 is a starting job status notification processing section. 7 is a job waiting processing section; 8 is a waiting zip re-execution notifying section; 10
0 is a computer system.

The embodiment shown in FIG. 1 includes a job startup processing unit l that dynamically requests submission of a job from a user program to a calculation processing system lOO, and a waiting condition necessary for synchronizing and waiting with the started job. Waiting condition registration processing ff153 for registering starting job waiting conditions in the waiting condition storage unit 2 for storing and in the waiting condition storage means 2
Then, the job execution processing section 4 executes the job requested by the job starting processing section 1, and checks whether or not the waiting conditions stored in the waiting condition storage section 2 match the status of the starting job. a waiting condition determination processing section 5 for making a determination; a starting job status notification processing section 6 for notifying the waiting condition determining processing section 5 of the starting job status each time the starting job status changes; Job waiting processing unit 7 for re-executing the user program when the user program is in the suspended state KL and the activated job is in a state that satisfies the waiting conditions, and notification of re-execution from the waiting condition determination processing unit 5 to job waiting processing unit 7 The job re-execution notifying unit 8 is comprised of a re-execution notifying unit 8 that sends a queuing job.

This method is a start-up waiting method for re-executing a user program that is currently stopped by monitoring and notifying the status of a job started in the computer system 100.

Next, the operation of this embodiment will be described below.

When data collection is completed using an online program, etc., data analysis or data updating is performed as a batch job, and a system jib is dynamically requested to be processed. After that, it is necessary to wait for the started batch job to finish processing and then start executing the online program again.

For example, during batch job processing, when data analysis processing is completed, the online program is re-executed.

At that time, the job startup processing unit 1 requests the submission of the job, stores the waiting condition “When data analysis is completed, execute the online program” in the waiting condition storage unit 2, and then responds to the job waiting process. Control is passed and the online program is suspended. The job execution processing unit 4 that receives the execution request from the job startup processing unit 1 executes the job.

Every time the status of the job being executed changes, the job status notification processing section 6 notifies the waiting condition determination processing section 5 of the job status.

When the status of the job being executed reaches the end of data analysis processing, the queuing condition processing section 5 receives the "notification of data analysis processing completion", passes control to the queuing job re-execution notification section 8, and starts the job queuing processing. The execution of the online program is notified to the unit 7.

(Effects of the Invention) As explained above, the present invention dynamically starts the job from the user program, registers the waiting conditions for synchronizing the user program and the starting job, and also registers the waiting conditions. After starting the job, the user program is kept in a waiting state until the status of the started job matches the above waiting condition, and when the waiting condition is met,
By starting re-execution, it is possible to wait for a program that corresponds to a change in the status of a job dynamically started from a program, and there is an effect that it is possible to provide flexibility in how to perform synchronization.
