Abstract
High reliability is achieved using logical computers without having to provide logical computers for a standby system in advance. By monitoring a status of an active system to predict failures, standby logical computers are newly created to switch logical computers running the system.
Claims10
A logical computer system comprising:
- monitoring means for monitoring execution statuses of programs running on a first logical computer;
- detection means for detecting an indication of a failure of the first logical computer from statuses of said monitoring means;
- and
- switching means, when an indication of a failure is detected, for creating a second logical computer and switching from the first logical computer to the second logical computer.
1 more element
A method for controlling a configuration of a logical computer system, comprising the steps of:
- monitoring execution statuses of programs running on a first logical computer;
- detecting an indication of a failure of the first logical computer from statuses of monitoring means;
- and
- when an indication of a failure is detected, creating a second logical computer and switching from the first logical computer to the second logical computer.
1 more element
A configuration control program of a logical computer system, designed to allow a computer for increasing reliability of logical computers to function as:
- monitoring means for monitoring execution statuses of programs running on a first logical computer;
- detection means for detecting an indication of a failure of the first logical computer from statuses of said monitoring means;
- and
- switching means, when an indication of a failure is detected, for creating a second logical computer and switching from the first logical computer to the second logical computer.
