Abstract

In a system in which requests to an application are distributed to computers on which the application in question is executed, computers are managed so as to prevent lowering of the service level of each application. A resource assignment manager 1 manages specifications of server computers 3. Further, the resource assignment manager 1 manages, for each application, correspondence between specifications of a server computer 3 and the number of processed requests in the case where the application in question is executed on a server computer 3 having those specifications. For each application, the resource assignment manager 1 monitors the number of received requests and the number of processed requests on server computers 3 to which the application in question, to specify an application deficient in resources. Then, the resource assignment manager 1 determines server computers 3 that are assigned additionally to the specified application, based on the required resource amount for the specified application, specifications of each of pooled server computers 3, and the correspondence between specifications of a server computer 3 and the number of processed requests expected when the specified application is executed on a server computer 3 having those specifications.

Claims20

Dependent claims

A resource assignment manager that determines computers on which an application is newly executed out of pooled computers, adopted in a system in which each of a plurality of applications is executed on at least one of a plurality of computers and requests to an application are distributed to and processed by computers on which said application is executed, comprising:

a resource information storage means, which stores specification information of each computer;
a processing capacity storage means, which stores, for each of said plurality of applications, correspondence between specification information of a computer and a number of processed requests per unit of time, said number being expected if the application in question is executed on a computer having said specification information;
a required resource amount estimation means, which specifies, for each of said plurality of applications, an application deficient in resources based on a difference between a number of received requests per unit of time and a number of processed requests per unit of time in each of computers assigned to the application in question, and calculates said difference in number of requests as a required resource amount for said application specified as one deficient in resources;
and
a configuration change means, which determines computers required for processing the required resource amount estimated by said required resource amount estimation means, out of said pooled computers, based on the specification information (stored in said resource information storage means) of each of said pooled computers, the specification information of a computer stored in said processing capacity storage means, and the correspondence between the specification information of the computer and the number of processed requests per unit of time, said number being expected if the specified application deficient in resources is executed on the computer having said specification information.

A resource assigning method in which a resource assignment manager determines computers on which an application is newly executed out of pooled computers, adopted in a system in which each of a plurality of applications is executed on at least one of a plurality of computers and requests to an application are distributed to and processed by computers on which said application is executed, wherein:

a storage unit of said resource assignment manager memorizes:
a resource information management table that stores specification information of each computer;
and
a processing capacity management table that stores, for each of said plurality of applications, correspondence between specification information of a computer and a number of processed requests per unit of time, said number being expected if the application in question is executed on a computer having said specification information;
an operation unit of said resource assignment manager performs:
a step, in which, for each of said plurality of applications, an application deficient in resources is specified based on a difference between a number of received requests per unit of time and a number of processed requests per unit of time in each of computers assigned to the application in question, and said difference in number of requests is determined as a required resource amount for said application specified as one deficient in resources;
and
a step, in which computers required for processing said determined required resource amount are determined out of said pooled computers, based on the specification information stored in said resource information management table of each of said pooled computers, the specification information of a computer stored in said processing capacity management table, and the correspondence between the specification information of the computer and the number of processed requests per unit of time, said number being expected if the specified application deficient in resources is executed on the computer having said specification information.
