Abstract

According to an aspect of the embodiment provides a method for controlling a processing device for distributing jobs among a plurality of job processing devices for executing the jobs, respectively. The method comprises the steps of: transmitting a job to one of the job processing devices to have the job executed by the one of the job processing devices; generating a procedure information for transmitting a continuation data from the one of the job processing devices before completion of execution of the job back to the processing device, the continuation data enabling another job processing device to continue execution of the job; and transmitting the procedure information to and receiving the continuation data from the one of the job processing devices.

Claims

1. A method for controlling a system including a first computer and a second computer for executing a job and a third computer for distributing the job to the first computer and the second computer, the method comprising:

generating, by the third computer, job script data;

generating, by the first computer, VM (Virtual Machine) image data for processing VM for executing the job before completion of execution of the job, the VM image data including state information of the VM at a given internal time, the VM including a starter function for monitoring a completion of job processing;

transmitting the generated VM image data from the first computer to the third computer;

transmitting the VM image data and job script data regarding the job from the third computer to the second computer when the second computer takes over the job;

receiving, by the second computer, the VM image data and the job script data from the third computer;

resuming, by the second computer, the job based on the VM image data and the job script data;

detecting, by the first computer, a completion of the job executed in the VM on the basis of the starter function; and

notifying, by the first computer, a batch system of the completion of the job.

2. The method according to claim 1,

wherein the transmitting the VM image data and job script data transmits the VM image data and the job script regarding the job from the third computer to the second computer upon detecting abnormal completion of the job by the first computer.

3. A system comprising:

a first computer and a second computer for executing a job; and

a third computer for distributing the job to the first computer and the second computer,

wherein the third computer generates job script data;

wherein the first computer generates VM (Virtual Machine) image data for processing VM for executing the job before completion of execution of the job;

the VM image data including state information of the VM at a given internal time, the VM including a starter function for monitoring a completion of job processing;

wherein the first computer transmits the generated VM image data to the third computer;

wherein the third computer transmits the VM image data and job script data regarding the job to the second computer when the second computer takes over the job;

wherein the second computer receives the VM image data and the job script data from the third computer;

wherein the second computer resumes the job based on the VM image data and the job script data; and

wherein the first computer detects a completion of the job executed in the VM on the basis of the starter function, and notifies a batch system of the completion of the job.

4. The system according to claim 3, wherein one of the first computer and the second computer executes the job by a virtual machine of the one of the first computer and the second computer.

5. The system according to claim 4 wherein the virtual machine has a common directory capable of accessing from the first computer and the second computer, wherein the one of the first computer and the second computer transmits completion information of the job to said common directory.
