Abstract

PURPOSE:To reduce the operating load of an operator by providing a means which stores the job executing environment information, a job processing state accumulating means, a means which calculates the execution waiting time rate, a means which decides the job multiplex degree, and a control means. CONSTITUTION:A job processing state accumulating means 1 accumulates the total execution waiting time and the execution starting job number for each job class. A time informing means 2 informs a means 1 of the time information every fixed time. Then the means 1 informs a calculation means 3 of the cumulative execution waiting time and the cumulative execution starting job numbers for all job classes every prescribed time. The means 3 calculates the execution waiting time rate for each job class based on the reference execution waiting time stored in a storage means 4 and gives the result of calculation to a job multiplicity deciding means 5. The means 5 checks whether the job multiplicity is changed or not. If even just a single job class having a change is confirmed, a control means 6 is started and changes the multiplicity of the job classes of a job execution means 7. As a result, a fine and optimum multiplicity can be set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a computer system, and particularly to control of job multiplicity.

[Prior Art] Conventionally, when controlling the job multiplicity, an operator manually inputs information necessary for changing the job multiplicity (change information) from a keyboard, and then changes the job multiplicity based on this change information. Severe control is in place.

[Problems to be solved by the invention] In conventional job multiplicity control, the change information required to change the job multiplicity is manually entered, so the job multiplicity cannot be changed without operator intervention. The problem is that it is not possible to change the .

Furthermore, in order to operate the system with optimal job multiplicity, it is necessary to constantly monitor the job processing status.

[Means for Solving the Problems] The present invention includes a job execution unit that executes jobs, sets job classes based on job characteristics, and sets job multiplicity for each job class to reduce system load. a computer system for controlling job execution environment information including job multiplicity for the entire system, maximum/minimum job multiplicity for each job class, standard waiting time, and current job multiplicity; A job processing status accumulation means for accumulating the total execution waiting time and the number of job execution starts of jobs in a job class; and a calculation means for calculating the execution waiting time ratio of each job class based on the cumulative execution waiting time and the cumulative number of execution starts. and.

determining means for determining the optimum job multiplicity for each job class based on the job execution environment information and the execution waiting time rate for each class; It is characterized by having a control means for controlling the degree of multiplicity.

[Example] Next, one embodiment of the present invention will be explained with reference to examples.

Referring to FIG. 1, the dynamic job multiplicity control method according to the present invention includes job processing status accumulation means 1.

Time notification means 2, calculation means 3, and storage means 4.

It includes a job multiplicity determining means 5, a job multiplicity control means 6, and a job execution means 7.

FIG. 2 shows the format of the job execution environment information stored in the storage means 4.

In FIG. 2, the job execution environment information includes the maximum multiplicity of the system 21, job class 22. Standard execution waiting time 23. Maximum job class multiplicity 24, minimum job class multiplicity 25. and the current job multiplicity 26.

Referring again to FIG. 1, job processing status accumulating means 1 accumulates the total execution waiting time and the number of jobs that have started execution for each job class. If there are multiple jobs waiting for execution in one job class, the execution waiting time of all the jobs is accumulated.

The time notification means 2 notifies the job processing status accumulation means 1 of time information at predetermined intervals. When the job processing status accumulation means 1 receives the one-hour information, it notifies the calculation means 3 of the accumulation of execution waiting times and the accumulation of the number of execution start jobs for all job classes at predetermined time intervals, and calculates the execution waiting time and execution start jobs. Clears the number of cumulative counters to zero.

The calculation means 3 calculates the execution waiting time rate for each job class.

On this occasion.

It is calculated as the standard execution waiting time stored in the execution waiting time rate storage means 4, but if the cumulative number of execution start jobs is zero, the average execution waiting time is processed as the maximum possible value.

Once the execution waiting time rate of each job class has been calculated,
The calculation means 3 passes this result to the job multiplicity determination means 5.

Here, the operation of the determining means 5 will be explained with reference also to FIG.

In process 31, the job classes and execution waiting time rates passed from the calculating means 3 are arranged in ascending order using the execution waiting time rates as keys. In process 32, it is checked whether the execution waiting time ratio is smaller than 1. If it is smaller, the process proceeds to step 33; if it is equal to or greater than 2, the process proceeds to step 36.

In process 33, it is checked whether the current job multiplicity is greater than the minimum multiplicity of the relevant job class stored in the storage means 4. If it is larger, proceed to process 34.

If they are equal or smaller, the process proceeds to step 35. In process 34, a value obtained by reducing the current job multiplicity of the relevant job class by one is stored in the current job multiplicity of the relevant job class in the storage means 4. In process 35, if there is a job class with a higher execution waiting time ratio, that job class is set as a job class to be determined for job multiplicity and the process returns to process 32; otherwise, the process returns to process 3.
Proceed to step 6.

In process 36, the job class with the largest execution waiting time rate is set as the job class for which job multiplicity is to be determined.

In process 37, it is checked whether the total job multiplicity of all job classes after the change is smaller than the maximum multiplicity of the system stored in the storage means 4. If it is smaller, the process proceeds to process 38; if it is larger, the process proceeds to process 312.

In process 38, it is checked whether the execution waiting time ratio is greater than 1.

If it is greater than 1, the process proceeds to step 39; if it is equal to or smaller than 9, the process proceeds to step 312.

In process 39, it is checked whether the multiplicity of the relevant job class is smaller than the maximum multiplicity stored in the storage means 4. If it is smaller, proceed to process 310, and if it is equal to or greater than 2, proceed to process 311
Proceed to.

In process 310, the current job multiplicity of the relevant job class is set to 1.
The increased value is stored in the current job multiplicity of the relevant job class in the storage means 4. In process 311, if there is a job class with a smaller execution waiting time ratio, that job class is set as the job class to be determined for job multiplicity and the process returns to process 37; otherwise, the process proceeds to process 312.

In process 312, it is checked whether there is a change in the job multiplicity, and if there is a change in even one job class, the control means 6 is activated, and if there is no change in all job classes, the process ends.

Here, the operation of the control means 6 will be explained with reference to FIG.

When the control means 6 is activated, in process 41.

The job class for which the job multiplicity is to be changed and the new multiplicity are input from the job multiplicity determining means 5.

In process 42, the multiplicity of the job class of the rejob execution means 7 is changed based on the information input in process 41.

[Effects of the Invention] As described above, according to the present invention, the degree of multiplicity of jobs can be dynamically changed without bothering the operator, thereby reducing the number of operations required by the operator. Also, by adjusting the maximum/minimum job multiplicity and standard execution waiting time of each job class.

This has the advantage that it is possible to set the optimum multiplicity in a fine-grained manner.
