Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timeout method for an interactive job with a limited number of licenses, and more particularly to a limited number of licenses for executing an interactive program in which the number of licenses, which is the number of concurrently executable programs, is limited. Time-out method for interactive jobs with limited number of licenses, in which timeout processing of interactive jobs with limited number of licenses is performed only when there is no free license number, which is the difference between the number of licenses and the total number of interactive jobs with limited number of licenses being executed It is related to the technology effectively applied to.

[0002]

2. Description of the Related Art Among conventional interactive programs executed by a computer system, there is a limit on the number of licenses, which is the number of interactive programs that can be executed simultaneously.

When a new license-limited interactive job for executing the above-mentioned license-limited interactive program is newly started, the total number of the license-limited interactive jobs already executed is the above-mentioned. If the number of licenses has been reached, the request to start the new interactive job with new license limit is rejected.

For this reason, in the conventional computer system for executing the interactive program whose license number is limited, a time limit is set for the license-number-limited interactive job being executed, and the time limit is exceeded. By the timeout method that unconditionally stops abandoned license limited interactive jobs, the number of running license limited interactive jobs is limited and a new license limited interactive job start request is issued. I was supposed to be accepted.

As a publicly known example close to the conventional timeout method for the interactive job with a limited number of licenses, Japanese Patent Application Laid-Open No. Hei 3
There is No. 22120. The outline is that, in a portable terminal device that supplies power from a battery, time registration means for registering an arbitrary time when the terminal device is not operated, and the terminal device is operated within the time registered in the time registration means. If there is not, equipped with means for turning off the power of the terminal device,
By registering any time in the time registration means,
The time to turn off the power when the terminal device is not operated is arbitrarily changed.

[0006]

The present inventor has found the following problems as a result of examining the above-mentioned prior art.

That is, in the conventional timeout method for a license-number limited interactive job, even if there is no request to start a new license-number limited interactive job, a license-number limited interaction that has been left over for a limited time is left. There was a problem that the type job was unconditionally stopped.

In the conventional timeout method for a license-number limited interactive job, the time limit is set to be longer so that the time limit is set when there is no request to start a new license-number limited interactive job. To prevent unconditional termination of license-limited interactive jobs that have been left over, a new license limit is set after the total number of running license-limited interactive jobs reaches the number of licenses. When a request to start an attached interactive job is issued, there is a problem that the waiting time until the new interactive job with limited number of licenses can be activated becomes long.

An object of the present invention is to provide a technique capable of preventing unnecessary timeout and improving the throughput of a computer system.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.
