Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a job operation management system, a job operation management method, and a storage medium which are installed in a computer system, for example.

[0002]

2. Description of the Related Art Conventionally, a job operation management system has been used in a computer system.

[0003] In a job operation management system in a computer system, a job is usually defined as a set of job steps which are arbitrary execution programs. In job status management, abnormal termination of a job is a state in which one or more job steps constituting the job have terminated abnormally.

The means for re-executing an abnormally terminated job includes a re-executing function from the beginning of the job, a re-executing function from an abnormally terminated job step, and a re-executing function from a check point immediately before the job is stopped. Generally provided.

[0005]

In the conventional job operation management system, when re-executing an abnormally ended job,
Re-execution from the abnormally ended job step or re-execution from the latest checkpoint is performed. In this case, data and environment necessary for the execution of the job step may not be prepared. For example, when trying to re-execute a job from a job step that ended abnormally,
If there is an inconsistency in the data file read by the program due to a system failure or other causes, the program started by re-execution cannot correctly process data.

In such a case, the job is re-executed after the data recovery processing is performed. However, since the job step from which the execution is resumed is determined in advance by a fixed value, the job to be resumed is determined. In order to match the steps with the data, complicated work such as manually executing a program that has already been completed may be required.

For example, if it is set that a job is re-executed from the first job step at the time of abnormal termination, unnecessary job steps are also executed.
The time required to re-execute the job becomes longer, which is not efficient.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and it is an object of the present invention to efficiently execute necessary and sufficient processing when re-executing a job whose execution has been terminated due to abnormal termination of the job. Job operation management system,
It is an object to provide a job operation management method and a storage medium.

A job execution history display unit for displaying a list of the execution history and its end state stored in the storage unit for each of the plurality of job steps; and a job execution history display unit for displaying a desired job history among the plurality of job steps listed by the job execution history display unit. Job start instructing means for instructing start from the first job step; Control means for restoring the system environment of the job step whose start is instructed by the instruction means from the information of the job step execution environment stored in the job execution history storage means, and re-executing the job from the instructed job step Are provided.

According to a fourth aspect of the present invention, there is provided a job operation management method, comprising: a step of sequentially executing a job including a plurality of job steps; and a job step execution environment information for each job step as a history of sequentially executing each job step. When the job ends abnormally, the system environment is restored based on the saved job step execution environment information, and the job is restarted from the abnormally ended job step or the immediately preceding job step. And a step of executing.

According to a fifth aspect of the present invention, there is provided a storage medium which causes a computer to sequentially execute a job including a plurality of job steps, and stores information of a job step execution environment for each job step as a history of sequentially executing each job step. When a job is abnormally terminated, a program that restores the system environment based on the saved job step execution environment information and re-executes the job from the abnormally terminated job step or the immediately preceding job step It is characterized by being stored in a computer-readable manner.

According to the first, fourth and fifth aspects of the present invention, information on a job step execution environment for each job step is stored in the job execution history storage means as a history of job steps sequentially executed by the job execution means. When a job ends abnormally, the system environment is restored based on the job step execution environment information stored in the job execution history storage unit, and the job is re-executed from the abnormally ended job step or the immediately preceding job step This eliminates the need for complicated work such as manually executing an already completed job as in the past, and also re-executes the job from the beginning, for example, and executes unnecessary job steps.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing the configuration of the job operation management system according to the first embodiment of the present invention.

As shown in FIG. 1, the job operation management system includes a job definition file 10, a job operation management control program 20, a job step (program) 3
0, and a job execution history information file 40 as a history storage unit. Job definition file 1
“0” stores job definition information defining the execution order of the jobs. The job operation management control program 20 has a job re-execution function. The job operation management control program 20 reads the job definition information stored in the job definition file 10, and executes the program 3 in accordance with the execution order specified by the read job definition information.
0 (job step) is executed. Further, the job operation management control program 20 stores history information and control information of the executed job steps in the job execution history information file 4.
Store to 0. These units are stored as software on a hard disk device of a computer or the like. Therefore, the hardware configuration generally provided in a computer (memory such as ROM and RAM, CPU, hard disk device, keyboard, mouse, monitor, printer, etc.)
And an operating system (hereinafter referred to as an OS), software (such as a driver program) necessary for operating hardware, and user applications. In addition, programs that function equivalently to these components are stored on floppy disks, CD-ROMs,
The information may be stored in a storage medium such as a flash memory and read into a computer.

Next, the operation of the job operation management system will be described. First, a job execution function and an abnormal recovery processing function in the job operation management system will be described.

A user creates a job by defining an execution order by combining a plurality of programs such as an operating system command (hereinafter referred to as an OS command) and a user application.

The job operation management control program 20 reads the job definition information stored in the job definition file 1 and executes the program 30 according to the execution order specified by the job definition information.

At this time, the job operation management control program 2
0 checks the end state of the job step at the end of each job step of the program 30, saves the history information and control information of the executed job step in the job execution history information file 40, and executes the next job step. Executes control such as job termination.

Here, for example, when one or more job steps included in a job are abnormally terminated when a certain job is completed, the job is handled as abnormally terminated by the job operation management control program 20.

When a job ends abnormally, the job operation management control program 20 operates the job re-execution function to re-execute the job with this as a start trigger.

In this case, the job operation management control program 20 usually restores the execution history of the job steps, the system environment variables set for the job execution, the job control information, etc., which were saved at the time of the job execution. Then, re-execution is started from the abnormal job step. In addition, there is a method of re-executing the job from the beginning. As described above, in addition to automatically re-executing a job with an abnormal end of the job as a start trigger, re-execution may be started by a user's designation from the console screen. Next, FIG.
The job recovery processing function of the job operation management system will be described with reference to FIG. As shown in FIGS. 2 and 3, the job operation management control program 20 executes a job definition file 1 in which a job definition is described at the start of execution of a job.
0, the job definition information is read into the memory (S10
1), create job definition information (S102).

The job operation management control program 20 reads the job step information to be executed in accordance with the job definition information (S103), and stores system environment variables set for executing or changing the job steps, status variables for job control, and the like. The job step execution environment is stored in the job execution history information file 40 (S104). The state variable is information of data to be processed by the program 30 itself.

Thereafter, the designated program 30 (job step) is executed (S105), and the end of the job step is waited for (S106).

When the execution of the program 30 is completed, the job operation management control program 20 stores the information of the execution result, the end state of the job step, and the updated job control information in the job execution history information file 40 (S10).
7). The job control information refers to, for example, data itself or a data file name which is executed in step 1 of the job step 1 and passed to the job step 2, and can be said to be transfer information between job steps. The job control information refers to information that is restored in job step 2 for job step 3.

Subsequently, if there is a job step to be executed next (No in S108), the above processing is repeated.

When all the job steps are completed (Yes in S108), and the job ends normally (S108).
Since the environment variables and control information stored in the job execution history information file 40 become unnecessary, the job operation management control program 20 deletes unnecessary information from the job execution history information file 40 by the unnecessary history deletion function. Then, only the execution history of the job step and the status of the normal end of the job are stored in the job execution history information file 40 as log information, and thereafter, a series of processes is normally ended.

On the other hand, if any one of the plurality of job steps does not end normally (No in S109), the job execution history information file is prepared in order to prepare for job re-execution as a job abnormal end. 4
The history information of 0 is stored as it is.

As described above, according to the job operation management system of the first embodiment, every time a job step is executed, the job operation management control program 20 stores the system environment variables for each job step in the job execution history information file 40. Job step execution environment information such as state variables for job control is saved, and when a job ends abnormally, job step execution environment information is read from the job execution history information file 40 to restore the job step execution environment. Then, since the job is re-executed from the abnormally ended job step, complicated work such as manually executing the already-completed job as in the related art becomes unnecessary, and, for example, the job is re-executed from the beginning. As a result, unnecessary job steps are also executed, and the time required to re-execute the job becomes longer Said was also eliminated it. In other words, by providing a job recovery function, history information for each job step is stored, and when a job ends abnormally, the job is re-executed from the abnormally ended job step or the immediately preceding job step. It can be carried out.

Also, when all the jobs are completed normally, the job execution history information such as system environment variables and job control information stored in the job execution history information file 40 is deleted. Since only the execution history of the job step and the status of the normal end of the job are stored in the log information 40, the storage area for storing the execution history of the job can be minimized. In other words, for a job that has been completed successfully due to the provision of the garbage collection function, the information necessary for re-execution of the job saved for each step is deleted, so that the storage area used for job management can be reduced. it can.

As a result, necessary and sufficient processing can be efficiently executed when re-executing a job whose execution has been terminated due to abnormal termination of the job.

Next, the second embodiment of the present invention will be described with reference to FIGS.

0 displays a console screen 61 which is a GUI screen for job re-execution on the monitor screen 60 as shown in FIG. 6 (S202).

In the console screen 61, in addition to the execution start button 62 and the cancel button 63, the execution histories and end states of all job steps are shown in a table format. The selection cursor 64 is displayed at the job step before the step (e.g., job step 3).

The user or the operator moves the selection cursor 64 on the console screen 61 by operating the mouse or the keyboard to select a desired job step, or clicks the execution start button 62 at a default position. The re-execution start step is notified to the console program 50, and the console program 50 inputs a job step to start execution to the job operation management control program 2 (S203).

With this input, the job operation management control program 20 executes the job step execution history stored in the job execution history information file 40 during normal job execution, system environment variables set for job execution, The base information of the job execution environment such as control information is read (S204), and the job execution environment necessary for re-execution of the specified job step is restored (S20).
5) Re-execute the job from the designated job step (S206).

In this embodiment, the job step before the job step which has become abnormal with the default value is selected on the console screen 61, but in addition, the job step which has become abnormal is selected. The job can be re-executed from the job step.

As described above, according to the job operation management system of the second embodiment, the execution history of the job step is stored when the job is executed, and the job is abnormally terminated, and the operator manually re-executes the job from the console screen. When performing the execution, the execution history and the end state of a plurality of saved job steps are displayed for each job step on the console screen 61, and a desired job among the already executed job steps is displayed on the console screen 61. The re-execution of the job is started from the job step only by the selection operation of the step by the user, so that the necessary and sufficient processing in the re-execution of the job can be efficiently executed.

That is, since the console screen display function and the job re-execution control mechanism from the console screen are provided, the job can be re-executed from the job step desired by the operator even if the job does not end abnormally.
