Abstract

PURPOSE:To efficiently execute a job by providing an urgent job execution priority alteration means which improves the allocation priority of respective resources as against the job designated by means of an urgent job instruction command and altering the job which is previously executed into the urgent job. CONSTITUTION:The urgent job instruction command designating the job which is made into the urgent job among the jobs under execution is inputted by an input means 1 and an urgent job instruction command analysis means 2 analyzes the inputted urgent job instruction command and recognizes the job which is made into the urgent job. The urgent job execution priority alteration means 3 improves the allocation priority of respective resources as against the job which the urgent job instruction command analysis means 2 recognizes. Thus, the job under execution is altered into the urgent job and the jobs can efficiently be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an emergency job execution method in a computer system.

[Conventional technology]

It has been a conventional practice to designate a job whose processing should be completed quickly as an emergency job, and conventionally, when starting a job, an instruction is given as to whether or not the job should be designated as an emergency job. In other words, in the past, it was necessary to specify whether or not to make the job an emergency job at startup, and it was not possible to change a normal job to an emergency job during execution.

For this reason, when an operator wants to quickly complete the processing of a job that is currently being executed, conventionally the operator inputs a pause command for jobs other than the above job to cause the other jobs to be paused, or I am trying to interrupt the job and start it again as an emergency job.

[Problem to be solved by the invention]

As mentioned above, in the past, other jobs were suspended or restarted as an emergency job, which made it impossible to execute the job efficiently or placed a burden on the operator. There was such a problem.

An object of the present invention is to enable a job in progress to be changed to an emergency job.

[Means to solve the problem]

To achieve the above object, the present invention provides, in a computer system capable of operating in a multiprogramming environment, an input for inputting an emergency job instruction command that specifies a job to be made an emergency job among jobs being executed in the computer system. means, an emergency job instruction command analysis means for analyzing an emergency job instruction command input from the input means and recognizing a job to be made into an emergency job, and allocation of various resources to the job recognized by the emergency job instruction command analysis means. Emergency job execution priority changing means for raising the priority is provided.

[For production]

The input means inputs an emergency job instruction command that designates a job to be an emergency job among the jobs being executed in the computer system. The emergency job instruction command analysis means analyzes the emergency job instruction command input from the input means and recognizes the job to be made into an emergency job. The emergency job execution priority changing means increases the allocation priority of various resources to the job recognized by the emergency job instruction command analysis means.

〔Example〕

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

FIG. 1 is a prosock diagram of an embodiment of the present invention.

The computer system 100 is capable of operating in a multi-programming environment, and includes an input/output means 1 consisting of a CRT, a keyboard, etc., and a job that analyzes an emergency job instruction command input from the input/output means 1 and converts it into an emergency job. The emergency job instruction command analysis means 2 recognizes various resources g<cpu. and an emergency job execution priority changing means 3 for increasing the allocation priority of memory, etc.).

Next, the operation of this embodiment will be explained.

For example, assume that job group 4 shown in FIG. 2 has been submitted to the computer system 100, and jobs 10, 20, and 30 are being executed. Note that each job 10, 20, and 30 has a priority for allocating various resources, and job 10 has a CPU priority of 11 and a memory usage priority of 12, job 20 has a CPU priority of 21, a memory usage priority of 22, and job 3 has a CPU priority of 21 and a memory usage priority of 22.
0 has a CPU priority of 31 and a memory use priority of 32.

Of the three running jobs included in job group 4,
For example, if the operator wants to complete the processing of job 20 quickly, the operator inputs an emergency job instruction command from the input/output means 1 instructing to make job 2o an emergency job.

The emergency job instruction command analysis means 2 analyzes the emergency job instruction command input from the input/output means 1, and
When it recognizes that it is requested to make 0 an emergency command, it passes information indicating job 20 and passes control to the emergency job execution priority changing means 3.

The emergency job execution priority change step 3 determines whether or not the job 20 specified by the information passed from the emergency job instruction command analysis means 2 exists in the job group 4 currently submitted to the computer system 100. investigate. If it does not exist, an error notification is sent to the input/output means 1 and the process is terminated. If job 20 exists, the CPU priority 21 and memory usage priority 22 of job 20 are set to C of the executing job other than job 20.
Set higher than PU priority and memory usage priority.

For details, see Job 10 regarding CPU priority.
's CPU priority 1l is "05" job 30 C
Since the PU priority 31 is "03", the CPU priority 2l of the job 20 is changed to "02" which is higher than either of them (the smaller the priority is, the higher the priority is). Regarding the memory usage priority, the memory usage priority 12 of job 10 is "04" and the memory usage priority 32 of job 30 is "07", so the memory usage priority 22 of job 20 is set higher than either of them. Change it to “03”.

By performing the above processing, the CP of job 20 is
U priority 21, memory usage priority 22
is the highest among the currently running job group 4,
Naturally, this job occupies the CPU and memory for a longer period of time than the other jobs 10 and 30, and is processed faster.

〔Effect of the invention〕

As explained above, the present invention is equipped with an emergency job execution priority changing means that increases the allocation priority of various resources to the job specified by the emergency job instruction command, and by inputting the emergency job instruction command, Since a job that is already running can be changed to an emergency job, it is easier to change the job compared to the conventional method where other jobs had to be paused or restarted as an emergency job. This has the effect of enabling efficient execution and reducing the burden on the operator.
