Information processing system
First Claim
1. An information processing system comprising a plurality of host systems each having resources including a plurality of instruction processors and a plurality of memory segments, wherein each of said host systems has a system status monitering and change instructing mechanism for managing statuses of said resources by a status management table, and said system status monitering and change instructing mechanism has means for instructing an enhancement or reduction of an ability of a self host system in accordance with said status management table in accordance with a load that is applied to the self host system.

Abstract
A system for enabling a system down due to a lack of ability to be avoided and enabling a dynamic backup to be performed by properly allocating resources to a processing ability is provided. Each of a plurality of host systems connected through an information network is provided with a system status monitering and change instructing mechanism which is physically independent of other component elements of the relevant host system, has a status management table of resources such as IPs, memory segments, and the like, and can enhance and reduce an ability of the host.

5. An information processing system comprising a plurality of host systems which mutually independently operate and include instruction processors and memory segments and in which there is a surplus in the resources, wherein
each of said host systems has a system status monitering and change instructing mechanism which is physically independent of other component elements in said relevant host system and has an operating status management table of said resources, and each of said host systems has a function for automatically enhancing or reducing an ability of a self host system in accordance with said status management table in accordance with a load that is applied to the self host system.

10. A control method for an information processing system having a plurality of instruction processors and a plurality of memory segments, comprising the steps of:
-
setting an upper limit value and a lower limit value of a mean use rate of said plurality of instruction processors as a stable operating range;
activating the inactive instruction processors when said mean use rate of said instruction processors exceeds said upper limit value during the operation; and
inactivating the active instruction processor when said mean use rate of said instruction processors is lower than said lower limit value during the operation. - View Dependent Claims (11)
