Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for inquiring and displaying job information in a distributed processing network system, and more particularly to a method for displaying job information in a large-scale system in which a large number of computers including different types are connected by a network. The present invention relates to a job information inquiry / display method suitable for the present invention.

[0002]

2. Description of the Related Art With the increase in the amount of processing performed using computers, a system (distributed processing network system) that connects a plurality of computers via a network and performs distributed processing may be constructed. Generally, a computer constituting a distributed processing network system includes:
In many cases, they are different models.

In a distributed processing network system, a terminal (job status monitoring system) in a system for monitoring information such as the status of a job being executed in a certain system or input to the certain system.
To be kept. Also, the information is displayed on a certain terminal (job information display system) in the system for the purpose of notifying a user of information of the job held in the job status monitoring system. The functions of the job status monitoring system and the job information display system can be realized in the same system. However, when the processing amount increases, it is often divided into two systems to distribute the load. In such a case, communication is often performed between the job execution system and the job status monitoring system, and between the job status monitoring system and the job information display system, and displayed in many cases. A job is a unit of processing configured to be processed by a computer, such as a numerical calculation, and job information (or job information) is a state of a single job. Not only that, the name and status of a group of multiple jobs
It takes various forms, such as the status of each job constituting a group of jobs. Therefore, the display form is not limited to a single form.

The conventional job information inquiry method has the following features.

Regardless of whether or not the job information has changed, the job information display system periodically inquires the job execution system and saves the returned information. This information is displayed when there is a request from the terminal on the display side.
Such a technique is described in JP-A-5-13963.

The job information display system holds information of all jobs, sends only the changed job information from the job execution system to the job information display system, and updates the information held by the job information display system. I do.

[0007]

The conventional job information inquiry method has the above-described features, and therefore has the following problems due to its configuration.

[0008] Since the inquiry is made periodically, the communication volume increases. This problem is particularly prominent in a large-scale system having a large number of job execution systems.

When distributed between a job status monitoring system and a job information display system, the storage capacity of both systems is reduced in order to maintain the same information in both systems. This problem also appears particularly remarkably in the case of a large-scale system.

[0010] The present invention has been proposed in view of the above points, and an object of the present invention is to provide a job information inquiry system that suppresses the amount of communication generated by an inquiry and the amount of information to be stored by the system. To provide.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides, for example, the state of a job being executed in a certain system on a distributed processing network system including systems of different models, or the state of a job input to the certain system. A job execution control means provided on the job monitoring side system for controlling the execution of all jobs according to the information in the job information management table. A processor-executing job information monitoring means provided in the system for monitoring information of a job executed by the processor and notifying the job information when the job information has changed; A job information monitoring unit that monitors information using a job information management table and a job information display side system It is determined whether it is necessary to inquire about the information of the job being displayed based on whether or not the updated information is in the job information storage table holding the information being displayed. A job information necessity determining means for determining whether or not the time has elapsed and inquiring only when necessary, and a job monitoring system provided in the job monitoring side system and corresponding to the job from the job information management table in response to a request from the display side Job information obtaining means for searching for and sending the information of the job, and display information updating means provided in the system on the job information display side and updating the information of the job being displayed with the job information sent from the job information obtaining means. Is provided.

[0012] Further, in order to introduce and use each of the above means in a distributed processing network system including systems of different models, the means can be stored in an installation medium in the form of a program executable by the system. By copying the program to the storage means, it is possible to take the form of a program that can be introduced and used in various systems.

When the information of a certain job changes, the job information monitoring means receives the changed job information and the job name from the job execution control means or the processor execution job information monitoring means, and updates the job information management table. The job information necessity determination unit is notified of the name of the job (job name) whose information has changed and the type of job information. The job information necessity determining means determines whether it is necessary to obtain the information of the notified job by determining whether the updated information is being displayed and whether a certain period of time has elapsed since the previous inquiry. Then, only the information determined to be necessary is queried to the job information acquisition means. Information that is being displayed on the job information display system and that can change with the passage of time is held in a job information storage table.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a numerical calculation system to which the present invention is applied. 10 is a job status monitoring system of the system, 20 is a job information display system, and 30 and 40 are job execution systems. In the embodiment of the present invention, only one job information display system and only two job execution systems are shown, but of course, a large number of job information display systems and job execution systems may be connected. It goes without saying that you can do it.

The job status monitoring system 10 has a job execution control unit 11, a data transmission / reception processing unit 12, a job information monitoring unit 13, a job information management table 14, and a job information acquisition unit 15. Numeral 11 controls the execution of the job for 30 and 40. Numeral 12 handles various types of data transmission and reception in a unified manner. 13 collects all job information executed by the present numerical calculation system, and 14
This is for referring and updating. Further, when detecting the change of the job information, the job 13 notifies the job 20 of the change. Numeral 14 is for recording job information for all jobs executed in the present system. 15 is 1
The job information recorded in 4 is searched and the collected result is
0. In the embodiment of the present invention, as will be described later, the job information monitored in the job information management table 14 is as shown in FIG.

The job information display system 20 has a data transmission / reception processing unit 21, a job information necessity determining unit 22, a display information updating unit 23, a timer 24, a screen 25, and a job information storage table 26. 21 has the same function as 12. 22 is based on the importance of the information of the job having the notified job name or the reliability of the information currently displayed,
Judge whether to make an inquiry, and only the information judged to be necessary is 1
5 to make an inquiry. The criteria for determining importance and reliability will be described later. 23 is for receiving the job information returned as a result of the inquiry made by 22 and updating the information displayed in 25 with the received job information. Numeral 24 is for measuring the elapsed time from the execution of the inquiry, and using it for determining the reliability of the displayed job information. Numeral 25 is for displaying job information and informing a user of the system or the like.
Reference numeral 26 is for holding a job information code of the job information to be displayed which can change with time. In the embodiment of the present invention, the job information storage table is as shown in FIG. 2, as described later.

The job execution systems 30 and 40 include a data transmission / reception processing unit 31, 41, a processor 32,
42, and processor execution job information monitoring means 33 and 43. 31 and 41 have the same functions as 12 and 21. 32 and 42 are for executing a job. Reference numerals 33 and 43 are for monitoring changes in information of the jobs executed in 32 and 42 and notifying 13 of the changes.

FIG. 2 shows the job information management table 14 and the job information storage table 2 according to the embodiment of the present invention.
6 is a table for explaining the configuration of FIG. In this system,
The job information includes “job name”, “job status”, “job execution start time”, “end code”, and “execution system name”. This table is for managing information on all jobs that can be executed by the present numerical calculation system. For example, the first line of the table corresponds to the job information of the job named JOB1. The job names are the names of all the jobs that can be executed by the systems 30 and 40. The job status is a status of each job. In this system, it is one of "waiting for input", "executing", "normal end", and "abnormal end". The job execution start time is a time at which execution of each job is started. For example, the job execution start time of JOB1 is 0:00.
Indicates that it will be executed immediately after. The end code is a code that the processor 32 or 42 notifies the processor execution job information monitoring unit 33 or 43 when the execution of the job is completed, and is a detailed classification of the end state. The execution system name indicates the name of a job execution system that executes each job. In this system,
Either “system 30” or “system 40”.
In addition, a job information code is defined as shown in the job information code definition 140 for those elements that can change with time among these elements constituting the job information. In this system, "job status" and "end code" are defined. The job information codes are stored in the systems 10 and 20.
This is for suppressing the communication amount during the period. To notify 20 that the information of a certain job has changed, 10
, The job name of the changed job and the type of the job information need only be notified to the server 20, and the changed job information itself is not necessary.

By defining the job information as described above, the following operations can be performed. That is, in the job information display system 20, the job names of all jobs,
There are two display modes: a schedule list screen that displays only the job status and the job execution start time and allows a list of job execution schedules to be displayed, and a job detail display screen that displays all job information of a single job. Take. Normally, the schedule list screen is displayed, and when the job status of a certain job is abnormally terminated, the job details display screen of the job is displayed, and by referring to the end code displayed in the screen, More detailed end information can be known.

FIG. 2 shows the job information storage table at this time. When the schedule list screen is being displayed, job names and job information codes indicating job statuses that can change with time are held for all jobs. When the job detail display screen of a certain job is being displayed, the job information code indicating the job name and the job status / end code is held for the relevant job. FIG.
Here, as an example, a job information storage table when the job detail display screen of JOB2 is being displayed is shown.

FIG. 3 is a block diagram for explaining a configuration necessary for introducing the present invention into a system. The present invention can be stored in the installation medium 53 in the form of a program executable by the system. By copying the program in this 53 into the storage means 51 using the reading means 52, it can be introduced into any system 50 and used.

FIG. 4 is a state transition diagram in the embodiment of the present invention. When this numerical calculation system starts,
The systems 30 and 40 can execute the job, and the system 10 is in a state where the job can be commanded and the job information can be monitored. The system 20 displays the job information. All the information to be displayed at this time is obtained by making an inquiry to 10 (state 001). When the job information changes, the system 30 or 40 immediately notifies the changed job name and information to 10 (state 002). 10 notifies 20 of the notified job name and the job information code corresponding to the notified job information (state 003). By notifying the job information code but not the job information itself, the communication amount between the systems 10 and 20 is suppressed.
20 determines whether an inquiry is necessary based on the job name and the job information code received from 10 (state 004). Only when it is determined that an inquiry is necessary, an inquiry is made to 10 (state 005), and the process returns to 001. If it is determined that the inquiry is unnecessary, nothing is performed and the process returns to 001. According to the method described above, the job information displayed at 25 is not updated unless a corresponding job is notified. In other words, even if the information of the corresponding job has changed, but the notification has not been performed due to a temporary communication failure or the like, 25
In some cases, the information being displayed may not match the information of the actual job. As a countermeasure against the above case, in the embodiment of the present invention, if the time measured by the timer 24 exceeds a certain value, the system 20 makes an inquiry to 10 (state 005) and returns to 001. Return. When an end command is issued by the operator in state 001, the present numerical calculation system ends.

FIG. 5 is a flowchart of the processing in the system 10. When the numerical calculation system starts, job information can be monitored (state 001). After the job execution start time 0:00 of JOB1 at 0:00 (step 104), 13 refers to the row of JOB1 at 14, and according to the execution system name (system 30),
11 is instructed to submit a job to the system 30 (step 105). At the same time, JOB1 at 14
Is updated from "waiting for input" to "executing" (step 106). Further 13 is 12 and 2
Via “1”, the name of the submitted job “JOB1” and the job information code “1” are notified to 22 (step 107). As a result of the determination in the system 20, when 15 receives the notification (inquiry) of the job name "JOB1" and the job information code "1" from 22 (step 1).
08), of the rows of JOB1 in the table 14, only the job status is obtained from 14 and 23 via 12 and 21.
(Step 109).

When the execution of JOB1 is completed normally (state 002), the job 13 receives the job name "JOB1" and the changed job information "normally completed" from 33 (step 103). 13 updates 14 with the received job information (step 106), and notifies 22 of the job name and job information code “1” whose job information has changed via 12 and 21 (step 107). System 20
As a result of the judgment, the job name "JOB
When a notification (inquiry) of “1” and the job information code “1” is received (step 108), only the job status in the row of JOB 1 of the table 14 is obtained from 14, and 12 and 2
It is returned to 23 via 1 (step 109). If the execution of JOB1 ends abnormally, 13 is set to 33
The process is the same as that of normal termination, except that the job information received from the server is "abnormal termination".

In the system 20, when the value of 24 exceeds a certain value, the job name “JO
By receiving "B1" and all the displayed job information codes, a job information inquiry of JOB1 is received (step 102). 15 obtains the information of JOB 1 indicated by 20 from 14 and returns the job information to 23 (step 109).

FIG. 6 is a flowchart of the processing in the system 20. When the numerical calculation system starts, the timer 24 is reset (step 201), and job information can be displayed (state 001). After the job execution start time 0:00 of JOB1 at 14:
The job status of JOB1 changes, and the job name "J
OB1 "and the job information code" 1 "are notified (step 204). 22 indicates that the information held in 26 is J
Based on whether or not the job status of OB1 is included, the necessity of inquiring the changed job information is determined. That is, when the schedule list screen or the job detail display screen of JOB1 is being displayed, the current information of JOB1 does not match the display content of the screen, so that an inquiry needs to be made. On the other hand, if the job detail display screen of the job other than JOB1 is being displayed, no inquiry is made. Therefore system 1
No communication occurs between 0 and the system 20 (step 205).

Only when it is determined that 22 makes an inquiry, 22 sends the job name “JOB1” and the job information code “1” to 15 to change the job status of JOB1 via 21 and 12. Query, result 10
The content displayed on the screen 25 is updated with the job status received from the server (step 206). Next, 24 is reset (step 201). 24 measures the elapsed time from the reset time.

When the information of a certain job changes, such as when the job execution is completed, the job name and the job information code are notified from 10 (step 204). When the job 1 ends normally, the job name “JOB1” and the job information code “1” are notified. 22 determines the necessity of inquiring the job information after the change based on the same criteria as in the case of job submission (step 205). That is, when the schedule list screen is being displayed, it is necessary to inquire only about the job status of JOB1. When the job detail display screen of JOB1 is being displayed, it is necessary to inquire about the job status and end code of JOB1. If the job details display screen of a job other than JOB1 is being displayed, no inquiry is made.

In the system 20, if the value of 24 exceeds a certain value, the 24 notifies the 22 (step 203). 22 determines from this notification that the displayed job information is unreliable, and 22 sends the job name “JOB1” and all the displayed job information codes to 15 to obtain the job information of JOB1. An inquiry is made, and the content displayed in 25 is updated with the job information received as a result (step 206). Then 24
Is reset (step 201). On the other hand, if the time measured at 24 does not exceed a certain value, 22
Determines that the reliability of the displayed job information is high at 25,
No inquiry is made unless the job name is notified from 13 (steps 203 and 204). Therefore, no communication occurs between the system 10 and the system 20.

FIG. 7 is a flowchart of the processing in the system 30 or 40. When the numerical calculation system starts, a job can be executed (state 001).
After 0:00 of the job execution start time of JOB1 in 14, 30 receives an instruction to submit JOB1 from 11 (step 302). Then, 30 inputs JOB1 to the processor 32, and 32 executes JOB1 (step 304). If the execution of JOB1 has been completed normally (step 305), 32 notifies 33 of an end code (step 306). Further, 33 notifies the job name and the changed job information to 13 via 31 and 12 (step 307).

The above description has been made with reference to the example of inputting and ending the execution of JOB1, but the processing performed in each system for all other jobs such as JOB2 is the same and independent.

[0033]

As described above, the job information inquiry / display system of the present invention has the following effects.

The system on the display side determines whether or not it is necessary before inquiring about job information, and therefore does not inquire about unnecessary information. Therefore, the communication amount between the systems can be suppressed as compared with a conventional system in which an inquiry is periodically made.

The system on the display side holds only the information being displayed, so that the amount of information to be stored by the system can be suppressed.
