Abstract

A management apparatus includes a job definition information storage section for storing, at each period, a job definition file including execution characteristics indicating the start condition of each job in the execution schedule, the estimated execution time of the job, the state of the job, and a restriction at the time of setting the start schedule of the job; an exclusion information storage section for storing exclusion definition information indicating the jobs to be executed exclusively from each other; a reset job specifying section for acquiring a first job definition file of a schedule to be executed and a second job definition file of an executed schedule, then extracting, as a reset job, an abnormally terminated job from the second job definition file, and extracting a job using the reset job and the issue message of the reset job as start conditions, to store the extracted jobs in a related job set table; an execution possible time zone calculating section for searching, as an execution possible time zone, a time zone enabling execution of the job stored in the related job set table, from the first job definition file based on the second job definition file and the exclusion definition information; a start schedule adjusting section for setting the start schedule of the job stored in the related job set table based on the execution possible time zone; and a start schedule time setting section for setting the start time of the job set in the first job definition file, based on the start schedule of the job stored in the related job set table.

Claims

1. A management apparatus for managing an execution schedule in which a start schedule of a job is set for each predetermined period, the management apparatus comprising:

a job definition information storage section for storing, at each predetermined period, a job definition file including execution characteristics indicating the start condition of each of the jobs in the execution schedule, the estimated execution time of the job, the state of the job, and a restriction at the time of setting the start schedule of the job;

an exclusion information storage section for storing exclusion definition information indicating the jobs to be executed exclusively from each other;

a reset job specifying section for acquiring a first job definition file that is a schedule to be executed and a second job definition file that is an executed schedule, then extracting, as a reset job, an abnormally terminated job from the second job definition file, and extracting a job using the reset job and the issue message of the reset job as start conditions, so as to store the extracted jobs in a related job set table;

an execution possible time zone calculating section for searching, as an execution possible time zone, a time zone enabling execution of the job stored in the related job set table, from the first job definition file on the basis of the second job definition file and the exclusion definition information;

a start schedule adjusting section for setting the start schedule of the job stored in the related job set table on the basis of the execution possible time zone; and

a start schedule time setting section for setting the start time of the job set in the first job definition file, on the basis of the start schedule of the job stored in the related job set table.

2. The management apparatus according to claim 1,

wherein when the execution characteristics in the job definition information include a characteristic of completion wait indicating a restriction that execution of a job be completed before execution of the same job set in an unexecuted execution schedule,

the reset job specifying section performs processing for setting, as a reset job, a job extracted from the second job definition file and having the execution characteristic of completion wait, and

the start schedule adjusting section performs processing for setting the start schedule of the reset job having the characteristic of completion wait, by specifying, among the execution possible time zones, one execution possible time zone which is prior to the start schedule of the same job as the reset job and is not shorter than the estimated execution time of the reset job.

3. The management apparatus according to claim 1,

wherein when the execution characteristics of the job definition information include a characteristic of parallel execution indicating a restriction that execution of a job can be performed independently of the start schedule of a job set in the unexecuted execution schedule,

the reset job specifying section performs processing for setting, as a reset job, a job which is extracted from the second job definition file and has the characteristic of parallel execution, and

the start schedule adjusting section performs processing for setting the start schedule of the reset job having the characteristic of parallel execution by specifying one of the execution possible time zones.

4. The management apparatus according to claim 1,

wherein when the execution characteristics of the job definition information include a characteristic of discontinuation indicating a restriction that the job start schedule of a job is not set in the case where the job is the same as a job set in the unexecuted execution schedule,

the reset job specifying section performs processing in which, when the first job definition file does not include the same job as the job extracted from the second job definition file and having the characteristic of discontinuation, the job having the characteristic of discontinuation is set as a reset job, and

the start schedule adjusting section performs processing for setting the start schedule of the reset jobs having the characteristics of discontinuation and parallel execution by specifying one of the execution possible time zones.

5. The management apparatus according to claim 1,

wherein when the job definition information includes priority of job execution,

the reset job specifying section performs processing, when an execution possible time zone not shorter than the estimated execution time of the reset job cannot be specified, for specifying a job having priority lower than the priority of the reset job from the first job definition file and cancelling the start schedule of the specified job, and

the execution possible time zone calculating section performs processing for searching a time zone enabling execution of the reset job from the execution schedule obtained by cancelling the start schedule of the specified job in the first job definition file, and for setting the searched time zone as the execution possible time zone, and

the start schedule adjusting section performs processing for setting the start schedule of the reset job on the basis of the execution schedule obtained by cancelling the start schedule of the specified job in the first job definition file.

6. The management apparatus according to claim 5, further comprising

a start schedule deleted-job information output section for generating and outputting start schedule deleted-job information indicating a job whose start schedule is canceled from the execution schedule in the first job definition file.

7. The management apparatus according to claim 1,

wherein when one of the execution possible time zones is specified on the basis of the execution characteristics of the reset job, the start schedule adjusting section performs processing for setting the start schedule of the reset job, by specifying an execution possible time zone having the earliest start time of the time zone.

8. The management apparatus according to claim 1, further comprising

a job set extracting section for generating, for the each reset job, a related job set by extracting a job started in association with the reset job with reference to the second definition file,

wherein the start schedule adjusting section performs processing for setting the start schedule of each of the jobs of the related job set on the basis of the execution characteristic of the job.

9. The management apparatus according to claim 1, further comprising

an output section for outputting a chart data illustrating the execution schedule including the start time and the estimated execution time of the jobs set in the first job definition file and of the reset job.

10. A processing method executed by a computer for managing an execution schedule in which a start schedule of a job is set for each predetermined period, the processing method comprising:

storing, at each predetermined period, a job definition file including execution characteristics indicating the start condition of each of the jobs in the execution schedule, the estimated execution time of the job, the state of the job, and a restriction at the time of setting the start schedule of the job in a job definition information storage section;

storing exclusion definition information indicating the jobs to be executed exclusively from each other in an exclusion information storage section;

acquiring a first job definition file that is a schedule to be executed, and a second job definition file that is an executed schedule;

extracting, as a reset job, an abnormally terminated job from the second job definition file and extracting a job using the reset job and the issue message of the reset job as start conditions, so as to store the extracted jobs in a related job set table;
