Abstract

PURPOSE:To hold the consistency of the operation state of a work processing job by holding supervisory information on the operation state of the work processing job, supervising the real operation state at every prescribed time and restarting it at abnormal time. CONSTITUTION:An online system 10 receives a processing request telegram from an input/output terminal equipment 1. A resident batch job (work processing job) 9 succeeds the processing request and executes a work processing. At that time, a job supervisory part 7 is automatically started in a prescribed time unit and supervises the operation state of the work processing job 9 based on a job management table 5. When it does not coincide with the operation state of the work processing job which a job supervisory means 2 recognizes, the operation state is altered so that they are matched, and the work processing job 9 is restarted. When the job 9 in the middle of execution is in a loop-state, it is compulsorily terminated, and the operation state is altered so as to restart the job. Thus, the consistency of an job operation which is recognized to be a real operation is held.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for monitoring a resident batch job of a computer system in which an online system receives a processing request message and a resident batch job takes over the processing request to realize business processing.

The present invention relates to a computer system capable of maintaining the consistency between the actual operating state of a resident batch job and the operating state of a business processing job recognized by a business processing job monitoring means.

[0003]

2. Description of the Related Art In the conventional resident job monitoring system,
A resident batch job (business processing job) for performing business processing is managed by the business processing job monitoring means, and the business processing job monitoring means performs start / stop processing of the business processing job according to a request input by the operator from the control terminal device. At the same time, the operation status of the job processing job was managed as follows. a. Initial state (state in which business processing jobs are not running at all) The state before the business processing job monitoring means executes the start processing of business processing jobs. Alternatively, the status after the business processing job monitoring unit receives the business processing job stop notification from the business processing job. b. Start-up status (state from the start of the job processing job until the job processing executable state) The job processing job monitoring means performs the job processing start start processing, and then the job processing job starts accepting job processing Waiting for notification to be sent. c. Business process executable status (a state in which a business process job is waiting for a business process request to be issued from the business process job monitoring unit) The business process job monitoring unit has received a business process acceptance start notification from a business process job, A state in which no processing request has been sent to the business processing job because there is no unprocessed processing request message. Alternatively, the business processing job monitoring mechanism has received a business processing end notification from the business processing job but has not issued a processing request to the business processing job because there is no unprocessed processing request message. d. Business processing status (status in which business processing job is performing business processing) After the business processing job monitoring means sends a processing request message to the business processing job, the business processing job sends a business processing end notification. Waiting for. e. Ended status (state in which the job processing job is performing stop processing) Waiting for the job processing job monitoring unit to send a notification to stop the job processing job after the job processing job monitoring unit issues a stop request to the job processing job State.

[0004]

In the conventional resident job monitoring method, only the operation status of the business processing job as described above is managed, and when the business processing job ends abnormally or the business processing loops. Since it does not recognize the operating state when it falls into a state, it has the following drawbacks. A. If the job processing job ends abnormally even though the job processing job monitoring unit does not perform the stop processing, the operating state recognized by the job processing job monitoring unit and the operating state of the actual job processing job become inconsistent.

Therefore, even if the business processing ends abnormally in the start-up state, the business processing job monitoring means waits for the business processing job to notify the start of the business processing acceptance.

Further, even if the business processing job ends abnormally in the business processing execution state, the business processing job monitoring means waits for the business processing job to notify the end of the business processing.

These waits are not canceled because the job processing job has already ended abnormally.
The job processing job is in a substantially blocked state.

Further, even if the job processing job ends abnormally in the job processing executable state, the job processing job monitoring means sends a processing request message to the job processing job when the job processing message is received, Wait for notification of business process completion.

This waiting is not canceled because the job processing job has already ended abnormally, and the job processing job is in a substantially closed state, and the message sent to the job processing job that has ended abnormally is also canceled. Remains unprocessed and is invalid. I. Even if the business processing performed by the business processing job falls into a loop state due to a fraudulent processing request message or the like, the business processing job monitoring means waits for the business processing job to notify the end of the business processing.

Such a waiting process is not canceled because the business processing is in a loop, and the business processing job is substantially blocked.

The present invention solves such a problem by ensuring consistency between the actual operating status of a resident batch job (business processing job) and the operating status of a business processing job recognized by the business processing job monitoring means. The object is to provide a computer system that can be maintained.

[0012]
