Problems solved by technology

In such a system, when optimal service assignment (assignment of service to the best computer) is performed only by setting policy information, it occurs that the execution of the service cannot be guaranteed as the load state of the computer changes
Specifically, when performing automatic service switching, there have been situations where the switching occurs frequently as the load changes; it is not clear what action to take when a low-priority service was previously executing; A service does not execute when the computer starts

Embodiment Construction

[0018] Embodiments of the present invention will be described below with reference to the drawings.

[0019] (first embodiment)

[0020] FIG. 1 is a block diagram illustrating a system configuration of a computer system according to a first embodiment of the present invention.

[0021] For example, in the computer system, four computers C1 to C5 are configured to be connected to each other through a network N. Among the computers C1 to C5, the computers C1 to C4 are set so that each computer operates under the control of an operating system (OS-1 to OS-4). Here, the computer C5 is a reserved computer (temporary computer), which is connected to the computer system through the network N. In addition to the computer C5, one or more reserved computers can be connected to the network N.

[0022] The cluster system is constituted by computers C1 to C4. In this cluster system, a cluster control section (CS1) 10 operates. The cluster control section 10 is a virtual machine obtain...

Abstract

In a computer system which achieves a cluster system using two or more computers, a cluster control section has an optimal service allocation section which assigns a service to an optimal computer in accordance with policy information, and a service relocating section which executes relocation of a service according to a change of a load state of the each computer.

Description

technical field [0001] In general, the present invention relates to a computer system composed of a plurality of computers, and in particular, to a technology of a cluster system that obtains an optimal service distribution function according to a failure or a load state of a computer. Background technique [0002] In recent years, a software technology called "cluster system" has been developed, which enhances the services provided at the client (user) by executing application programs for a computer system composed of multiple computers (such as servers). Handle performance and reliability. A cluster system has a function for scheduling a certain service operating on a computer system to the best computer during computer startup or in response to a failure or a change in load status, and can improve availability or load distribution. [0003] Cluster systems are broadly classified into load distribution type cluster systems emphasizing load distribution functions and high...
