[0001] 1. Field of the Invention [0002] The present invention relates to a failure recovery system in an information processing apparatus, and more particularly, to a batch job recovery system.

[0002]

2. Description of the Related Art As a method of restarting a job after a system failure, for example, Japanese Patent Application Laid-Open No. 3-225434 discloses a means for storing information for restarting a job, information on steps being executed, and a restart method. There is disclosed a configuration that includes information described in a (executing job detailed information storage device), includes a unit that refers to the stored information after a system failure and restarts a user step interrupted by the system failure.

[0003] For example, Japanese Patent Application Laid-Open No. Sho 62-177633 discloses a method in which a failure recovery management module is applied to a batch program. A batch job failure recovery management method has been proposed in which a file update without any inconsistency can be realized only by executing the job, and a batch job can be automatically started without selecting an abort job.

[0004]

However, the conventional control method described above has the following problems.

As a first problem, the above-mentioned Japanese Patent Laid-Open Publication No.
In the automatic job restart processing method described in Japanese Patent Application Laid-Open No. 225434, only a batch job being executed at the time of occurrence of a system failure is to be restarted.

The reason for this is that the information to be referred to is described in the in-execution job detailed information storage device, and whether the execution result is normal or abnormal, when the job execution is completed, This is because the information is deleted.

The above-mentioned Japanese Patent Application Laid-Open No. 3-225434 does not mention at all a mechanism for automatically starting a recovery job for restoring a job when it ends abnormally.

For this reason, in the case of a pattern C or D in FIG. 2 schematically showing a job execution pattern, the job schedule is stagnated unless an operator intervenes.

[0009] The second problem is the above-mentioned JP-A-3-2254.
In the job restart method described in Japanese Patent Application Publication No. 34-34 and the automatic job restart processing method described in Japanese Patent Application Laid-Open No. Sho 62-177633, the only recovery method is to perform restart. is there.

The third problem is the above-mentioned Japanese Patent Application Laid-Open No. Sho 62-177.
In the method described in Japanese Patent Application Laid-Open No. 633, a dedicated device such as a previous operation job execution history device must be newly installed.

Accordingly, the present invention has been made in view of the above problems, and has as its object to detect and recover (recover) a batch job interrupted by a system failure.
It is to provide a system that enables the following.

[0012]

According to the present invention, a batch job started under the control of a job automatic running system is executed after a system failure has occurred, and the batch job interrupted by the system failure has occurred. ,
A job status search unit that searches a job information storage database that stores the status of a batch job started by the job automatic running system, and a job that treats a batch job whose status is being executed when a system failure occurs as an abnormal end An abnormal end notification unit and a recovery job start unit that starts a recovery job again for a batch job that is being recovered by a recovery job and whose recovery job has been interrupted due to a system failure.

In the present invention, the recovery job started by the recovery job starting means is treated as re-execution, normal end,
The alternative job activation and no action are displayed on the screen as options, and re-execution, normal termination, and activation of the alternative job are controlled according to the operator's selection.

Further, in the present invention, the job status search means refers to the attributes of the batch job stored in the job information storage database, and for a job determined to be a simple rerun-capable job, the job automatic running The system may further include a simple rerun enabled job restart notification unit that notifies the system of the restart of the job.

Embodiments of the present invention will be described below. According to a preferred embodiment of the present invention, a job recovery system for recovering a batch job started under the control of a job automatic running system when a system failure occurs, after the system failure has occurred, A job status search unit (see FIG. 1) that searches for a batch job interrupted by the job information storage database (2 in FIG. 1) that stores the status of the batch job started by the automatic job running system (1 in FIG. 1). 31), a job abnormal end notifying unit (32 in FIG. 1) for treating a batch job whose status is being executed at the time of occurrence of the system failure as abnormal termination,
For a batch job that is being recovered by a recovery job and the recovery job is interrupted due to a system failure, a recovery job starting unit (33 in FIG. 1) configured to start the recovery job again is configured. .

More specifically, in the embodiment of the present invention, the job status search means (31 in FIG. 1) includes a job information storage database (FIG. 1) for storing the status of the batch job started by the automatic job running system. 2) is searched, and the job status of the batch job is checked. If the job status is “executing”, the schedule number of the batch job is sent to the job abnormal end notifying means (32 in FIG. 1). Notice.

The job abnormal end notifying means (32 in FIG. 1) receiving the notification of the schedule number notifies the job automatic running system by inputting the abnormal end notification command of the batch job to the mail. Upon receiving the abnormal termination notification for the batch job, the job automatic running system changes the job status of the batch job stored in the job information storage database from “executing” to “abnormal termination”, and performs recovery. Start the job.

The recovery job is provided to the operator as (1) "re-execute" and (2) "handled normally" as a treatment for the abnormally terminated batch job.
A screen is displayed so as to select one of (3) "start an alternative job" and (4) "do nothing".
(A) When "re-execute" is selected and input, a restart notification of the batch job is input via the mail server 7, and (b)
When “treat normally” is selected and input, a normal end notification is input via the mail server. (C) When “start alternative job” is selected and input, the alternative job is started.

The job status search means searches the job information storage database and checks the job status of the batch job. If the job status is "abnormal end", the recovery job activation means (33 in FIG. 1) In response to the notification of the schedule number of the batch job, the recovery job starting means having received the notification of the schedule number starts a recovery job for the batch job,
The activated recovery job is provided to the operator as a treatment for the abnormally terminated batch job.
"Re-execute", (2) "Treat normally", (3)
A screen is displayed so as to select one of “start an alternative job” and (4) “do nothing”. (A) When “re-execute” is selected, a restart notification of the batch job Is sent via mail, and if (b) "Treat normally" is selected, a notification of normal end is sent via mail. (C) If "Start alternative job" is selected, substitute Start the job.

Further, in the embodiment of the present invention,
A simple rerun enabled job restart notification unit (34 in FIG. 5) is further provided, and the job status search unit refers to the attribute of the batch job stored in the job information storage database and is determined to be a simple rerun enabled job. With respect to the job, the simple rerun-capable job restart notifying unit notifies the simple rerun-capable job restart notifying unit of the schedule number of the job. May be notified.

In the embodiment of the present invention, (a) a batch job which has been executed under the control of the automatic job running system is replaced with the batch job interrupted by the occurrence of the system failure after the occurrence of the system failure.

After the system failure occurs, when the system failure batch job support means 3 is started, first,
The job status search means 31 searches the job information storage database 2.

If the job status is "executing" as a result of the search, it is considered that the job was being executed when a system failure occurred (pattern B in FIG. 2). 7, an abnormal end notification of the job is issued. Note that the mail 7 is a notification (command) to the job automatic running system 1.
To accumulate and manage.

When the automatic job running system 1 receives the abnormal termination notification stored in the mail server 7 at the time of startup, it updates the status of the job from "executing" to "abnormal termination". In addition, the recovery job 6 is started to prevent the job schedule from stagnating.

On the other hand, as a result of searching the job information storage database 2, for a batch job whose job status is “abnormal termination”, the recovery job 6 started by the automatic job running system 1 because the job has terminated abnormally is being executed. It is assumed that a system failure has occurred (Pattern D in FIG. 2). For such a job, the job status in the job information storage database 2 has already been abnormally terminated, and there is no need to send another “abnormal termination” notification.

Therefore, the recovery job 4 which operates in the same manner as the recovery job 6 is transferred to the automatic job running system 1.
Start on behalf of.

The recovery jobs 4 and 6 are (1) re-executed as a treatment for a batch job that has ended abnormally.
One of (2) normal termination, (3) activation of an alternative job, and (4) nothing is selected and input from the operator response input screens 10 and 11.

Here, when "start an alternative job" of (3) is selected, alternative jobs 8 and 9 are started.

In this way, by detecting and recovering a job interrupted due to a system failure, it is possible to prevent a job schedule from stagnating.
