Description

  The present invention relates to a batch job execution control method implemented by a computer system, and in particular, a batch job processing time zone is predetermined, and extension of the time zone is strictly prohibited, but processing cannot be completed within the predetermined time zone. The batch job processing relates to a technique that is effective when applied to batch job execution control in a computer system, which is allowed to be processed in the next batch job processing time zone.

  When executing batch processing in a computer system, it is common to execute a batch job during a predetermined time period. On the other hand, there are various types of data handled by batch processing of computer systems, and when processing data that varies in data amount, such as when the amount of data is extremely large or small, the processing time zone specified at the peak In some cases, it cannot be completed by the end time.

  In such a case, conventionally, the batch job being processed is forcibly interrupted at the end time of the time zone, and the processing of the interrupted batch job and unprocessed data are processed in the next batch processing time zone. Inevitably, the end time of the predetermined batch processing time zone was extended by human judgment.

Even if the batch job processing service is delayed, the system is stopped at the system service end time specified in advance, and the batch job that could not be executed within the time will be processed at the business date that should be executed at the next system service. There is one that can be executed (for example, see Patent Document 1).
JP 2000-112887 A

  However, in the past, when batch processing is performed within a limited time zone, if the end of the batch job exceeds the end time of the default processing time zone, it is in operation at the end time There was no choice but to forcibly interrupt the batch job or extend the end time of the processing time zone.

  In addition, the batch job that is being executed at the system service end time is also forcibly interrupted and the batch job that cannot be executed within the time including the forcibly interrupted batch job Is executed at the next system service, so if the end of the batch job exceeds the end time of the default processing time zone, there will always be a batch job that does not end normally.

  Therefore, if the batch job is forcibly interrupted, the processing of the interrupted batch job is wasted and the end status of the batch job is abnormally ended. It is necessary to determine whether it is forcibly interrupted due to a failure or a failure, and it is difficult to make this determination automatically.

  In addition, for example, in the case of a batch job that processes one-day data or one-month data for each customer, if the processing is interrupted in the middle of processing, the result of processing with the batch job and the result of being unable to be processed However, there is a problem that consistency cannot be obtained in the subsequent processing.

  In addition, if the batch processing time zone is unavoidably extended, there is an effect on subsequent processing of the batch processing, and there is a problem that it is difficult to automate because judgment by a person is indispensable.

  Therefore, an object of the present invention is to avoid the processing of a batch job exceeding the end time of the default time zone in a computer system that executes the batch job in the predetermined time zone, and to end the end time of the default time zone. It is an object of the present invention to provide a batch job execution control method capable of avoiding abnormal termination of a batch job due to forcible interruption of the batch job and extension of a batch processing time zone due to human judgment.

  In the batch job execution control method according to the present invention, a batch processing time zone for executing a batch job is defined, batch processing is performed repeatedly in sequence during the batch processing time zone, and batch processing that cannot be processed during the batch processing time zone. Is a batch job execution control method in a system that is allowed to be executed in the next batch processing time zone as long as the processing execution order is observed, and information on the batch job to be executed before the batch job is executed. If the batch job end time is calculated based on the current time information and the calculated batch job end time exceeds the end time of the batch processing time zone, the next batch processing is not executed without executing the batch job. It will be executed during the time zone.

  Further, the batch job execution control method according to the present invention has a predetermined batch processing time zone for executing a batch job, and repeatedly performs batch processing sequentially during the batch processing time zone, and cannot be processed during the batch processing time zone. Batch processing is a batch job execution control method in a system that is allowed to be executed in the next batch processing time zone as long as the execution order of the processing is observed, and relates to a batch job executed during the batch processing time zone. The last batch job end time is calculated based on the information and the current time information. If the calculated batch job end time exceeds the end time of the batch processing time zone, the start time of the batch processing time zone is advanced. The batch job is executed.

  According to the present invention, the batch job is not processed beyond the end time of the predetermined batch time zone, and the forced interruption of the batch job due to the end time of the predetermined batch time zone can be avoided.

  Furthermore, according to the present invention, it is not necessary to determine whether the cause of abnormal termination of a batch job is due to a time zone end time or a failure.

  Further, according to the present invention, since unnecessary processing such that the time zone end time is exceeded and processing is performed again next time is eliminated, computer resources can be used efficiently accordingly.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a configuration diagram showing a configuration of a batch processing unit for implementing a batch job execution control method according to an embodiment of the present invention.

  In FIG. 1, a batch processing unit 10 includes a batch processing execution control unit 20 that controls execution of a batch job, a batch job information file 30 that is necessary for the batch processing execution control unit 20 to control execution of the batch job, and input data. The information file 40 includes a batch job 50 executed in a batch processing time zone, and an input data storage file 60 in which input data processed by the batch job 50 is stored.

  The batch processing unit 10 is provided in a computer system, for example, and the batch processing execution control unit 20 executes a batch job, and the processing result is used by the computer system.

  The batch processing unit 10 is provided in a batch processing computer provided in the computer system, and uses the processing result of the batch job by a processing system connected to the batch processing computer or the batch processing computer. It may be.

  The batch job information file 30 includes a batch time zone information record 31 in which information on a time zone for executing the batch job 50 is stored, a name for each batch job 50, an input file name input by the batch job 50, and data It has a batch job information record 32 in which information on one processing time is stored.

  The input data information file 40 has an input data information record 41 that holds the file name of each input data stored in the input data storage file 60 and the number of data items.

  Next, the processing operation of batch job execution control by the batch processing execution control unit 20 of this embodiment will be described.

  First, the batch processing execution control unit 20 refers to a batch job information record 32 storing a processing time and input file name for each batch job data and an input data information record 41 held in the input data information file 40. The time required for processing the batch job 50 is calculated.

  The batch processing execution control unit 20 acquires the current date and time (system date and time held in the computer) from the computer system or batch processing computer in which the batch processing unit 10 is provided, and the calculated processing time and The batch job end time is calculated from the acquired current date and time, and by comparing with the batch time zone end time stored in the batch time zone information record 31, it is determined whether or not the batch job 50 can be executed.

  If the batch job end time does not exceed the batch time zone end time, the batch process execution control unit 20 activates the batch job 50, and the batch job 50 inputs the input data storage file 60 and executes the process. If the batch job end time exceeds the batch time zone end time, the subsequent batch job is not started.

  Here, the details of the process for determining whether or not to execute the batch job executed in the batch time period by the batch process execution control unit 20 will be described.

  FIG. 2 is a flowchart showing processing for determining whether or not to execute a batch job executed in a batch time period. The batch job to be executed is determined based on the scheduling information of the batch job, and then whether or not to execute the batch job to be executed is determined. The process to determine is shown.

  First, a batch job to be executed is determined based on preset batch job scheduling information or the like (S100).

  Then, the batch processing execution control unit 20 inputs a batch time zone end time (a) registered in advance, a processing time (b) per piece of data of the execution target batch job, and an input file input by the execution target batch job. The name (c) is acquired from the batch time zone information record 31 and the batch job information record 32 stored in the batch job information file 30 (S101), and the input data information based on the acquired input file name (c) From the input data information record 41 stored in the file 40, the number of data items (d) to be processed by the batch job to be executed is acquired (S102).

  Then, the processing time (A) of the batch job is calculated from the processing time (b) per data item of the execution target batch job and the number of data items (d) processed by the batch job (S103). Further, in order to acquire the current date and time, the system date and time (e) are acquired from the computer system and the batch processing computer (S104), and the batch job processing time (A) is added to the acquired system date and time (e). ) Is added to calculate the batch job end time (B) to be executed (S105).

  Then, the batch processing execution control unit 20 compares the calculated batch job end time (B) to be executed with the batch time zone end time (a), and the batch job end time (B) is the batch time zone end time (a ) ((B) <= (a)) is determined (S106).

  If it is determined in S106 that the batch job end time (B) falls within the batch time zone end time (a) ((B) <= (a)), the batch job to be executed is executed (S107). If it is determined that the batch job end time (B) does not fall within the batch time zone end time (a) ((B)> (a)), the execution of the batch job to be executed is stopped and the current The batch job execution processing in the batch processing time zone is terminated, and unprocessed data is set as data for the next batch processing target (S108).

  Next, a specific example of batch job execution control by the batch processing execution control unit 20 of this embodiment will be described.

  3 to 6 are explanatory diagrams for explaining specific examples of batch job execution control by the batch processing execution control unit.

  First, as shown in FIG. 3, the batch job information record 32 of the batch job information file 30 stores information “BT001”, “BT002”,..., “BT00X” as a batch name. The batch job stores the information that the input file name is “A” and the processing time of one data is “1 minute”, and the batch job of “BT002” has the input file name “B” and the processing of one data Information that the time is “2 minutes” is stored, and the batch job “BT00X” has the information that the input file name is “X” and the processing time of one data is “10 minutes”.

  Further, the input data information record 41 of the input data information file 40 stores information “A”, “B”,..., “X” as input file names. Information with the number of cases “10” is stored, information with the file name “B” stores information with the number of data “10”, and data with the file name “X” has the number of data “2”. Is stored.

  The batch time zone information record 31 of the batch job information file 30 stores “0:00” as the start time and “5:00” as the end time. Is the batch time zone.

  First, as shown in FIG. 3, when “0:00” of the batch time zone start time is reached, a batch job “BT001” is first determined based on the scheduling information of the batch job.

  The batch job of “BT001” has the input file name “A”, the number of data of the input file name “A” is “10”, and the processing time of one data of the input file name “A” is “1 minute”. Therefore, the processing time of the batch job “BT001” is “10 minutes”, and the end time of the batch job is “0:10”.

  Since this end time falls within the batch time zone end time “5:00”, the batch job “BT001” is activated and executed.

  Then, as shown in FIG. 4, when the processing of the batch job “BT001” is completed (finished to “0:10”), the batch job “BT002” is determined based on the scheduling information of the batch job.

  In the batch job “BT002”, the input file name is “B”, the number of data of the input file name “B” is “10”, and the processing time of one data of the input file name “B” is “2 minutes”. Therefore, the processing time of the batch job “BT002” is “20 minutes”, and the end time of the batch job is “0:30”.

  Since this end time falls within the batch time zone end time “5:00”, the batch job “BT002” is activated and executed.

  Then, as shown in FIG. 5, when the processing of the batch job before “BT00X” is completed (finished at “4:50”), the batch job of “BT00X” is determined based on the scheduling information of the batch job.

  For the batch job of “BT00X”, the input file name is “X”, the number of data of the input file name “X” is “2”, and the processing time of one data of the input file name “X” is “10 minutes” Therefore, the batch job “BT00X” has a processing time of “20 minutes”, and the end time of the batch job is “5:10”.

  Since this end time does not fall within the batch time zone end time “5:00”, the batch job “BT00X” is activated NG and is carried over to the next day without being executed.

  As shown in FIG. 6, when the next day's batch time zone start time “0:00” is reached, first, the batch job “BT00X” carried over from the previous day is determined based on the scheduling information of the batch job. To do.

  For the batch job of “BT00X”, the input file name is “X”, the number of data of the input file name “X” is “2”, and the processing time of one data of the input file name “X” is “10 minutes” Therefore, the batch job “BT00X” has a processing time of “20 minutes”, and the end time of the batch job is “0:20”.

  Since the end time falls within the batch time zone end time “5:00”, the batch job “BT00X” is activated and executed.

  Thereafter, the batch job is determined based on the scheduling information of the normal batch job of the day, and the same processing is performed.

  As described above, in this embodiment, the end time of the batch job to be executed is calculated in advance, and if it does not fall within the batch time zone end time, the execution of the batch job is stopped by stopping the execution of the batch job. It is possible to avoid the batch job being forcibly terminated due to the end of the batch time zone.

  Next, a specific example of the batch job information file 30 will be described.

  FIG. 7 shows an example of a batch job information file.

  In FIG. 7, a batch job information file 30 is a batch job information in which a batch time zone information record (1 record) 31, a processing time per data for each batch job, a file name input by the batch job, and the like are stored. There are records (multiple records) 32, and each record is managed by key information set in each record.

  In the example shown in FIG. 7, the batch time zone information record (1 record) 31 is a record whose key value is all zero, and the batch job information record 32 having a plurality of records is managed by the key value assigned sequentially.

  Then, information on the batch time zone start time and batch time zone end time of the all-zero record, which is a key value of the batch time zone information record (1 record) 31 (for example, start time 2:00, end time 5:00) Is applied to a plurality of batch job information records 32 each having a key value assigned sequentially thereafter, and is used as batch time zone information of the batch job.

  Also, information on the batch time zone start time and batch time zone end time of another all-zero record, which is a key value of the batch time zone information record (1 record) 31 (for example, start time 0:00, end time 2: 00), the batch time zone information is applied to a plurality of batch job information records 32 each having a key value sequentially attached thereto.

  As a result, records having two types of meanings can be arranged in the batch job information file 30.

  In this embodiment, whether or not the batch job can be executed is determined based on whether or not the batch job processing end time exceeds the time based on the batch time zone end time. It is also possible to execute a batch job by accelerating the start time of the batch time zone. In this case, it is possible to increase the processing amount of the batch job.

  In this embodiment, the batch job processing time is calculated based on the information in the batch job information file 30 and the input data information file 40. However, if the information can be used to calculate the batch job processing time, The processing time of the batch job may be calculated based on other information.
