Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a job processing apparatus for managing and executing jobs based on job priorities and the like.

[0002]

2. Description of the Related Art One of processes applied to a general-purpose computer such as a mainframe or a host computer (hereinafter, referred to as a "host") is to simultaneously execute a plurality of jobs by subdividing an execution time. There is a time division process. In the time division processing, a job processing apparatus having an automatic job execution function, a control function, an execution state monitoring function, and the like has recently appeared, and the job processing efficiency has been dramatically improved.

Prior to the advent of the job processing apparatus, when a job is executed on a certain host, the job is started by an input from a user, and the job is executed regardless of the load applied to the host at that time. It had been. Therefore, when a large number of jobs are executed at the same time, the host becomes overloaded, and it takes a long time to finish each job. That is, among jobs to be actually executed, there are jobs having various priorities, such as a job that is to be executed immediately and a result is to be obtained as soon as possible, and a job that needs to be completed within a few days. However, since those jobs were handled in the same manner, a serious problem occurred such that a high-priority job was not executed due to overload of the host.

A job processing device has appeared to solve such a problem, and the job processing device has a function of controlling the number of concurrently executing jobs. Job processing unit 2 in the typical conventional job processing apparatus
FIG. 9 shows a functional block diagram of the “0”.

[0005] In FIG. 9, a job processing section 20 in the conventional job processing apparatus includes a job information setting section 21, a pre-job execution processing section 22, a job execution section 23, a job unit 24, and a queue unit 25. Be composed.

When the name of the job to be executed is input, the job information setting section 21 creates job information including attribute information of the job (name of the job, time at which the execution of the job was instructed, etc.) The created job information is output to the job execution pre-processing unit 22.

When job information is input from the job information setting unit 21, the job execution pre-processing unit 22 determines whether or not the job can be executed. , Job information in job unit 2
4 and outputs the job unit number of the job unit 24 of the storage destination to the job execution unit 23 and instructs execution of the job. The job execution pre-processing unit 22
If it is determined that the job cannot be executed,
The job information is temporarily stored in the queue unit 25.
The job execution pre-processing unit 22 sends the job information from the queue unit 25 in the order stored in the queue unit 25 when it determines that the job being executed in the job execution unit 23 ends and the job can be executed. It moves to the job unit 24 and instructs the job execution unit 23 to execute the job.

When a job execution instruction and a job unit number are input from the job execution pre-processing unit 22, the job execution unit 23 reads out job information stored in the job unit 24 corresponding to the input job unit number. When the job is executed and the job is completed, the job information is deleted from the job unit 24.

The job unit 24 is a system resource constituted by a storage medium for storing job information of a job to be executed, for example, a RAM, and comprises job units for the number of jobs that can be executed simultaneously. That is, the job unit 24 can be considered as a container for executing a job, and when job information is stored in all the job units of the job unit 24,
This means that the same number of jobs as the job units are being executed.

The queue unit 25 is a job unit 2
When the job execution pre-processing unit 22 determines that the job cannot be executed and the job execution preprocessing unit 22 determines that the job cannot be executed, the job execution pre-processing unit 22 is configured by a storage medium, such as a RAM, for temporarily storing job information of the job to be in a waiting state. System resources. That is, the job information stored in the queue unit 25 is moved to the job unit 24 in the order stored in the queue unit 25 and executed as soon as the job unit 24 becomes available.

Next, the operation of the above-described conventional job processing apparatus will be briefly described. First, when the user inputs a name of a job to be executed on the job processing apparatus, the job name is input to the job information setting unit 21 in the job processing apparatus. Then, the job information setting unit 21 creates job information, and stores the created job information in the job execution pre-processing unit 2.
Output to 2.

Next, the job execution pre-processing section 22 searches the job unit 24 for an empty job unit. As a result, when there is an empty job unit, the job information is written in the job unit, the job unit number is output to the job execution unit 23, and the execution of the job is instructed. Then, the job execution unit 23 reads the job information from the job unit of the input job unit number and executes the job.
If there is no free job unit, the pre-job execution processing unit 22 does not perform the processing, and in that case, temporarily stores the job information in the queue unit 25. The job execution pre-processing unit 22 transfers the job information stored in the queue unit 25 to the job unit 24 as soon as the job unit 24 becomes available, outputs the job unit number to the job execution unit 23, and executes the job information. Instruct. The above is the basic operation of the conventional job processing apparatus that controls the simultaneous execution of jobs.

[0013]

However, in the conventional job processing apparatus, the number of job units is limited, and only the number of job units is limited so that jobs can be executed simultaneously. This is because, when a job exceeding the number of job units is executed, the server that executes the job is overloaded, causing a problem that processing efficiency is significantly reduced.

For this reason, a job exceeding the number of job units is normally in a queuing wait state, and the processing of the job is not executed until the job unit becomes empty.

However, depending on the contents of a job waiting to be executed, some jobs have a high priority. For example, there are jobs that must be completed by a predetermined date. However, the deadline may elapse before execution depending on the load state of the server.

In such a case, the operation manager has to set the priority of the submitted job in consideration of the situation in advance, and adjust the order of the submitted jobs. Further, even if the order is adjusted at the time of submission, a job executed before that time unexpectedly requires processing time, and as a result, the deadline may have passed.

An object of the present invention is to monitor a job with a high urgency having a deadline designation or the like and, when the presence of a job with a high urgency is detected, temporarily restrict the execution of other jobs. The priority of the job is to prevent processing delays of important jobs.

[0018]

According to the first aspect of the present invention,
In a job processing apparatus that manages execution of a job, which is a request unit of processing executed on a computer device, a simultaneous execution unit that simultaneously executes a plurality of jobs by time-division processing, and a determination unit that determines the urgency of the job If the presence of a job with a high degree of urgency determined by the determination means is detected, the time allocated to the job is increased by the concurrent execution means, and the simultaneous execution means is assigned to another low priority job. And execution restriction means for temporarily restricting the time allocated to the program.

According to the first aspect of the present invention, in a job processing apparatus for managing execution of a job which is a request unit of processing executed on a computer device, the simultaneous execution means performs time-division processing on a plurality of jobs. The determination means determines the urgency of the job, and the execution restriction means
If the presence of a job with a high degree of urgency determined by the determination unit is detected, the time allocated to the job is increased by the concurrent execution unit, and the job is assigned to another low priority job. Temporarily limit the time allotted for

Therefore, a job with a high degree of urgency can be detected from jobs being executed and waiting for execution, and the job with a high degree of urgency can be executed by restricting the execution of other jobs with a low degree of urgency. Processing time for a job with a high degree of urgency is secured, and processing up to the processing time limit is guaranteed. for that reason,
Since the expiration of the processing time limit can be prevented, the reliability of the job processing apparatus can be improved.

According to a second aspect of the present invention, there is provided a job processing apparatus for managing the execution of a job, which is a request unit of processing executed on a computer, in a simultaneous execution means for simultaneously executing a plurality of jobs; Determining means for determining the urgency of the job, and when the presence of a job with a high degree of urgency determined by the determining means is detected, temporarily restricts the execution of other running jobs, An urgent execution unit for executing and submitting a job with a high degree of urgency by the simultaneous execution unit; and executing the job whose execution has been temporarily restricted when the execution of the job with a high degree of urgency has been completed by the emergency execution unit. Execution restriction canceling means for restoring the state;
It is characterized by having.

According to the second aspect of the present invention, in the job processing apparatus which manages the execution of a job which is a request unit of processing executed on the computer, the simultaneous execution means executes a plurality of jobs simultaneously. The determination means determines the urgency of the job waiting to be executed, and if the presence of a job with a high degree of urgency determined by the determination means is detected, the emergency execution means Is temporarily restricted, and the job with a high degree of urgency is executed and submitted by the simultaneous execution means.The execution restriction release means, when the execution of the job with a high degree of urgency by the emergency execution means ends, Restores the execution status of a job whose execution has been temporarily restricted.

Therefore, the urgency of the job waiting for execution can be determined, the execution of the job being executed is restricted, and the job waiting for execution with high urgency is executed. Processing up to the processing deadline of a job with a high degree of urgency is guaranteed, and it is possible to prevent the processing deadline from being overdue due to a delay in execution input. In addition, as soon as the processing of a job with a high degree of urgency is completed, the restriction on the job whose execution has been restricted is released, so that the optimum allocation of the processing can be performed according to the urgency of the job.

[0024]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 8 are diagrams illustrating an embodiment of a job processing apparatus 1 to which the present invention has been applied.

The job processing apparatus 1 has a job monitoring processing unit 16 for monitoring the processing date of a job stored in a queue unit 15 for temporarily storing a job in an execution waiting state. Is a device that determines the priority of a job by determining the time allowance up to the processing date, and finishes the execution of the job on a predetermined processing date by preferentially executing a job with a high priority. .

First, the configuration will be described. FIG. 1 is a block diagram illustrating an internal configuration of the job processing device 1 according to the present embodiment. In FIG. 1, the job processing device 1
PU2, input device 3, RAM4, display device 5,
It comprises a printing device 6, a storage device 7, and a storage medium 8, and each part except the storage medium 8 is connected by a bus 9.

CPU (Central Processing Unit) 2
Are application programs designated from among various application programs corresponding to the job processing device 1 stored in the storage medium 8 in the storage device 7, and various application programs corresponding to various instruction signals input from the input device 3. Data and the like are stored in the RAM 4, various processes are executed according to the application program stored in the RAM 4 according to the input instruction and the input data, and the processing results are stored in the RAM 4 and output to the display device 5. indicate. Then, the CPU 2 inputs the processing result stored in the RAM 4 from the input device 3 to the storage device 7.
In the storage destination of the storage medium 8 in the storage area.

The CPU 2 has a job information setting unit 11
And a job execution pre-processing unit 12 and a job execution unit 13 (corresponding to the simultaneous execution unit and execution restriction unit according to claim 1 or the simultaneous execution unit and execution restriction release unit according to claim 2). , A job monitoring processing unit 16 (corresponding to the judging means according to claim 1 or 2 and the urgent execution means according to claim 2), and these units and the job unit 14 in the RAM 4 described later. And queue unit 1
5 constitutes a job processing unit 10 relating to job assignment and execution as shown in FIG. The job processing unit 10 executes a job execution request process (see FIG. 3) as a process related to job assignment / execution, and each unit of the job processing unit 10 is a job execution request subroutine. It executes information setting processing (see FIG. 4), pre-job execution processing (see FIG. 5), job execution processing (see FIG. 6), and job monitoring processing (see FIG. 7). Less than,
The configuration of each unit of the job processing unit 10 and the processing of a subroutine executed by each unit will be briefly described.

In FIG. 2, the job information setting section 11
The job information to be executed is set based on the input of the "job name" to be executed and the "processing date" of the job, and the job information is created by combining the information with the job requested to be executed. 12 is a device that outputs the job information created for the job 12.

When job information is input from the job information setting unit 11, the job execution pre-processing unit 12 performs a job pre-execution process. The pre-job execution process includes an executable judgment process,
It consists of normal execution processing and queuing processing. The normal execution process is a process of storing job information in the job unit 14 when the job is executable, notifying the job execution unit 13 of the stored job unit number, and instructing execution of the job. The queuing process is a process of temporarily storing job information in the queue unit 15 when the job unit 14 is full and cannot be executed. The job stored in the queue unit 15 is moved from the queue unit 15 to the job unit 14 when the queue unit 15 receives the end notification of the job being executed from the job execution unit 13.

When the job execution unit 13 receives a job execution instruction from the job execution pre-processing unit 12, the job execution unit 13 reads the job information stored in the designated job unit number from the job unit 14 and executes the job. A time-division arithmetic processing device (not shown) is provided inside. When the execution of a job is instructed by the job pre-processing unit 12, the time-division arithmetic processing unit executes a plurality of jobs simultaneously by time-division processing. When the execution of the job is completed, the job information is deleted from the job unit 14 and a job completion notification is sent to the job execution pre-processing unit 12.

The job execution unit 13 sends a job having no margin on the due date from the job monitoring processing unit 16 (hereinafter, this job is referred to as a “priority job”. ). When a priority job execution instruction is received, the execution of another job is temporarily suspended to execute the priority job, and only the priority job is executed with priority. I do. Alternatively, the priority job is executed by limiting the processing time allocated to the other job being executed to a certain time or less. In executing the priority job, the job executing unit 13 directly reads out the job information stored in the queue unit number notified from the job monitoring processing unit 16 to perform the job. Then, when the execution of the priority job is completed, the job information is deleted from the queue unit 15, and the execution of the temporarily suspended or restricted job is resumed in the same manner as before the execution of the priority processing is instructed.

The job unit 14 includes a job execution unit 13
Is a storage medium in which job information of a job executed by the job execution unit 13 is stored. In other words, the job unit 14 can be considered as a container for executing a job. When all the job units 14 have a job, the same number of jobs as the number of job units are being executed. Will be. The job unit 14 specifies, as variables representing the internal information of the job unit 14, the “number of free job units” indicating the number of job units for which job information is not registered, and the address of each job unit of the job unit 14. For example, a “job unit identifier” is stored.

The queue unit 15 includes the job unit 1
If the job information is included in all of the job information No. 4, job information relating to the job to be executed next is temporarily stored. This job information is transferred to the job unit 14 by the job execution pre-processing unit 12 as soon as the job unit 14 becomes available,
The job is executed by the job executing unit 13. However, when the priority processing is executed by the job monitoring processing unit 16,
The job is directly executed by the job execution unit 13 without being moved to the job unit 14.

The job monitoring processor 16 monitors the processing date of the job information stored in the queue unit 15 and determines the margin of the processing date. When a job that cannot be processed, that is, a priority job is detected, the job execution unit 13 is instructed to execute the priority of the detected priority job. This priority execution instruction is performed by notifying the job execution unit 13 of a queue unit number or the like as a queue unit identifier for specifying the queue unit in which the priority job is stored. The margin of the processing date is
This is performed in accordance with the due date margin calculation process, which is an internal process of the job monitoring processing unit 16, and the due date margin is determined based on the processing due date and the like in the job information.

In FIG. 1, the input device 3 includes a keyboard, a mouse, and the like provided with a cursor key, a numeric input key, and the like, and outputs to the CPU 2 a signal indicating a key pressed on the keyboard and a mouse position signal. .

A RAM (Random Access Memory) 4 stores C
The PU 2 forms a program storage area for expanding various data when executing the various application programs, and also forms a storage area for the job unit unit 14. The RAM 4 stores the job information setting unit 11, the pre-job execution processing unit 12, the job execution unit 13 of the CPU 2.
Job execution request processing (see FIG. 3) executed by
Various variables, data, etc. relating to the job information setting process (see FIG. 4), the pre-job execution process (see FIG. 5), the job execution process (see FIG. 6), and the job monitoring process (see FIG. 7) are temporarily stored. To form a memory area.

The display device 5 is a CRT (Cathode Ray Tub).
e) and the like, and displays display data input from the CPU 2. The printing device 6 is configured by an ink jet printer, a laser printer, or the like, and prints various data according to a print signal input from the CPU 2.

The storage device 7 has a storage medium 8 in which programs, data and the like are stored in advance, and this storage medium 8 is constituted by a magnetic or optical storage medium or a semiconductor memory. The storage medium 8 is fixedly provided in the storage device 7 or is detachably mounted. The storage medium 8 is processed by various application programs corresponding to the job processing apparatus 1 and various processing programs. Stored data and the like.

The program, data, and the like stored in the storage medium 8 may be configured to be received and stored from another device connected via a communication line or the like. A storage device provided with the storage medium may be provided on the other connected device side, and the program and data stored in the storage medium 8 may be used via a communication line.

Next, the operation will be described. First, the job execution request process will be described with reference to FIG. The job execution request process is a process from when the job information is input to the job information setting unit 11 to when the job execution ends.
It comprises a job information setting process, a job pre-execution process, a job monitoring process, and a job execution process. In the following description of the operation, for the sake of simplicity, the same processing as that of the conventional job is performed for a normal job, and the description is omitted. The job stored in the queue unit 15 is described as a priority job. I do. FIG. 3 is a flowchart illustrating the operation of the job execution request process executed by the job processing unit 10.

In FIG. 3, the job processing unit 10 first executes the job information setting process for the job input from the input device 3 by the job information setting unit 11 (Step S).
100) Then, the job execution pre-processing unit 12 executes the job execution pre-processing including the execution judgment processing for judging whether the input job can be executed and the normal execution processing and the queuing processing (step S200).

In step S200, the queuing process is executed, and the job monitoring processor 16 performs the job monitoring process including the due date margin calculation process and the priority execution instruction process on the job stored in the queue unit 15 (step S200). Step S300).

In step S300, the job monitoring unit 16 determines that the job has no due date margin, that is, it is a priority job. A priority job execution process is performed (step S400).

Next, the job information setting process will be described with reference to FIG. FIG. 4 is a flowchart illustrating an operation of the job information setting process executed by the job information setting unit 11. The job information setting unit 11 sets job information, which is the first process in the job execution request process.

In FIG. 4, first, the job information setting unit 1
1 receives a job input by a user from the input device 3 (step S101). Next, the job information setting unit 11 sets a job name (step S102) and a job processing due date (step 103) in association with the job input in step S101. Further, the job information setting unit 11 sets other job information such as a process execution identification flag and a priority execution identification flag (step S104). The above is the job information input process, and the job information setting unit 11 outputs the set job information to the job execution pre-processing unit 12.

Next, the job pre-processing performed by the job pre-processing section 12 will be described with reference to FIG. FIG.
5 is a flowchart showing a pre-job execution process executed by the pre-job execution processing unit 12.

First, the job execution preprocessing section 12 constantly monitors whether there is an input of job information from the job information setting section 11, that is, whether or not a job is input (step S201). If there is no job submission,
The job execution pre-processing unit 12 determines whether or not there is a job whose execution has been completed (hereinafter, the executed job is referred to as a completed job), that is, whether there is a job completion notification to be described later from the job execution processing unit 13. The process proceeds to monitoring for presence or absence (step S207).

If it is determined in step S201 that the job information has been input, the job
Determines whether there is a free space in the job unit 14 (step S202). If it is determined that there is no free space in the job unit 14, the pre-job execution processing unit 12 registers the job information in the queue unit 15 (step S20).
3), proceed to step S207.

If it is determined in step S202 that there is a free space in the job unit 14, the job execution preprocessing unit 12 reduces the number of free job units stored in the job unit 14 (step S204). Register the job information (step S20
5). Next, the job execution unit 13 is notified of the job unit identifier of the job unit 14 in which the priority job is stored, and instructs execution of the job (step S20).
6).

Next, the job pre-processing unit 12 determines whether or not there is an end job (step S207).
If it is determined that there is no completed job, the process proceeds to a determination as to whether all job processes have been completed (step S208). If it is determined that all the job processes have been completed, the job execution pre-processing unit 12 ends the job pre-execution process. If it is determined in step S208 that all the job processes have not been completed, the pre-job execution processing unit 12 determines whether or not there is input of job information from the job information setting unit 11 (whether or not there is a job input). (Step S20)
Move to 1).

If it is determined in step S207 that there is an end job, the job pre-processing unit 12 proceeds to determine whether or not there is job information in the queue unit 15 (step S209).

If it is determined in step S209 that the queue unit 15 has job information, the job information is read from the queue unit 15 (step S21).
0), the process proceeds to step S205 in which the job information is registered in the job unit 14.

If it is determined in step S209 that no job is stored in the queue unit 15,
The number of empty job units of the job unit 14 is increased (step S211), and the process proceeds to step S208. The above is the job pre-execution processing.

Next, the processing performed by the job execution unit 13 will be described with reference to FIG. FIG. 6 shows the job execution unit 1
3 is a flowchart illustrating an operation of a job execution process executed by a job execution unit 3; In the job execution process, two types of jobs, a normal job and a priority job, are executed.

First, the job execution unit 13 constantly monitors the normal job execution instruction from the job execution pre-processing unit 12 and the priority job execution instruction from the job monitoring processing unit 16 (step S401). If it is determined that there is no job execution instruction, the process proceeds to step S412 where it is determined whether there is an end job.

In step S401, if it is determined that there is a job execution instruction, the job execution unit 13 determines whether a priority job is being executed (step S401).
402). If it is determined that the priority job is being executed,
Wait for the execution of the priority job to end (step S
403). If it is determined that the priority job is not running,
The job executing unit 13 proceeds to step S404 in which it is determined whether or not there is a priority job execution instruction.

If it is determined in step S404 that there is no instruction to execute a priority job, the job execution unit 13
The job information is read from the job unit 14 (step S405), and the normal job is executed, that is, the job is simultaneously input to the time-division processing unit (step S405).
406), and proceed to step S412.

In step S404, if the job execution unit 13 determines that there is an instruction to execute a priority job,
Temporarily suspend or restrict the execution of other jobs (step S
407), the job information is read from the queue unit 15 (step S408). Next, the job execution unit 13
Executes the priority job alone (step S409), and after the execution is completed, the job execution pre-processing unit 12
A job end notification is issued, and the end job information is deleted from the queue unit 15 (step S410). Next, the job execution unit 13 resumes the execution of the other job whose execution has been interrupted or the execution of which has been restricted or cancels the execution restriction (step S411). After that, the procedure moves to step S412.

In step S 412, if the job executing unit 13 determines that there is a completed job, the job executing unit 13 notifies the job pre-processing unit 12 of the completion of the job, and deletes the job information of the completed job from the job unit 14. (Step S413). In step S412, when the job execution unit 13 determines that there is no finished job,
The process proceeds to a determination as to whether all job execution processes have been completed (step S414).

In step S414, if the job executing unit 13 determines that all the jobs have not been executed, the process proceeds to step S401, and repeats the job execution process until all the jobs have been executed. .
In step S414, if the job execution unit 13 determines that all the job executions have been completed, the job execution process ends. The above is the job execution process.

Next, the processing performed by the job monitoring processing section 16 will be described with reference to FIG. FIG. 7 is a flowchart illustrating the operation of the job monitoring process executed by the job monitoring processing unit 16. The job monitoring processing unit 16
The processing deadline of the job stored in the queue unit 15 is monitored, and when a priority job occurs, a priority execution instruction is issued to the job execution unit 13.

The job monitoring processor 16 constantly monitors whether job information is registered in the queue unit 15 (step S301). When it is determined that the job information is not registered in the queue unit 15, it is determined whether all the job processes have been completed (step S).
307).

If it is determined in step S301 that the job information has been registered in the queue unit 15, the job monitoring processing unit 16 executes a due date margin calculation process described later based on the job information of the job (step S301). S
302), it is determined whether there is a due date margin of the job (step S303). If it is determined that the job has a due date margin, the process proceeds to step S307.

In step 303, if the job monitoring unit 16 determines that the job has no due date margin, ie, determines that the job is a priority job, the job execution unit 13 registers the queue unit of the queue unit in which the priority job is registered. An identifier is notified, and execution of the priority job is instructed (job priority execution processing) (step S304). Then, it waits for the execution of the priority job to end (step S
305), it is determined whether or not the execution of the priority job has been completed (step S306).

If the execution of the priority job has not been completed, the job monitoring processing section 16 continues to wait for the completion of the execution of the priority job (step S305), and if the execution of the priority job has been completed, all the job processes have been completed. It is determined whether or not this is the case (step S307).

If it is determined in step S307 that all the job processes have not been completed, the process proceeds to step S301, and the job monitoring process is repeatedly executed. If it is determined that all the job processes have been completed, the job monitoring process is completed.

Here, the due date margin calculation processing in step S302 in FIG. 7 will be described with reference to FIG. In step S301 in FIG. 7, when the job monitoring processing unit 16 determines that the job information is registered in the queue unit 15, the job monitoring processing unit 16 executes a due date margin calculation process.
First, the current time (T1) is obtained (step P30).
1).

Next, the processing date (T2) is acquired from the job information set in the job information setting section 11 (step P302), and the estimated time (T3) required for completion when the job is executed alone is completed. ) Is obtained (step P303). If the job is in a standby state while being processed due to a temporary suspension of the execution, the predicted time T3 is corrected based on the already processed time (T4) (step P304). That is, the already executed time T4 is subtracted from the required predicted time T3 obtained in step P303, and this is newly set as the required predicted time T3.

Next, a due date margin (X) is calculated from these T1, T2, and T3 (step P305). here,
The job monitoring processor 16 determines whether the due date margin X is greater than 1.5 (Step P306).

When it is determined that the due date margin X is less than 1.5, it is determined that there is no due date margin (step P30).
7), the due date margin calculation processing ends. If it is determined that the due date margin X is greater than 1.5, it is determined that there is a due date margin (step P308), and the due date margin calculation processing ends.

As described above, the job processing apparatus 1 to which the present invention has been applied has the attribute of the processing date for executing the job, and monitors the processing date of the job in the execution waiting state. Since the job execution time can be changed, the job processing time can be secured, the job processing time limit can be guaranteed, and the processing date can be prevented from being overrun, so that the reliability of the job processing apparatus 1 can be improved. realizable.

When executing a high priority job,
The execution capacity of the job processing apparatus 1 is reduced by restricting the execution of other jobs and releasing the execution restriction of the other jobs whose execution has been restricted after the priority execution of the high-priority job is completed. It can be optimally assigned to processing.

It should be noted that the present invention is not limited to the contents of the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention. Of the job monitoring processing unit 16, the job monitoring processing unit 16 including the job in the job unit is subjected to the execution date monitoring. Based on the priorities of all the jobs,
A configuration in which the job is preferentially executed may be adopted.

According to the first and fourth aspects of the present invention, a job having a high degree of urgency can be detected from jobs being executed or waiting to be executed, and another job having a low degree of urgency can be executed. Since the job with a high degree of urgency can be executed with restriction, the processing time of the job with a high degree of urgency is ensured, and processing until the processing time limit is guaranteed. Therefore, the expiration of the processing time limit can be prevented, and the reliability of the job processing apparatus can be improved.

According to the second and fifth aspects of the present invention, the urgency of a job waiting for execution can be determined, the execution of a job being executed is restricted, and the Since the execution is performed, the processing until the processing expiration of the job with high urgency while waiting for the execution is guaranteed, and it is possible to prevent the processing expiration from being overdue due to the delay of the execution input. In addition, as soon as the processing of a job with a high degree of urgency is completed, the restriction on the job whose execution has been restricted is released, so that the optimum allocation of the processing can be performed according to the urgency of the job.

According to the third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, the execution time limit given as the attribute of the job is compared with the current time to determine the time. To determine the degree of urgency based on the target margin, when inputting a job, the user only has to input the processing date of the job in addition to inputting the job name, etc., and complete the execution of the job by the processing date. The job processing apparatus can easily determine the degree of urgency by comparing the processing date with the current time.
