Abstract

In one embodiment, a method for allocating programs to resources suited to operating conditions thereof comprises generating composition management information for a plurality of resources based on management information relating to performance and capacity of each of the resources. The composition management information includes identification information for the resources used by a plurality of programs. The method further comprises searching for and locating the composition management information of a resource identified by the identification information for each of the programs, based on the composition management information of the resources, and generating program information which associates composition management information of each of the programs with the composition management information of the located resource; and outputting information indicating that a resource abnormality has occurred with one of the programs, in cases where the composition management information of the resource which is associated with the program in the program information corresponds to one or more rules for detecting a resource abnormality in the program.

Claims

1. A method of allocating a virtual resource to a business application, said virtual resource being managed by a management server, the method comprising steps of:

providing a resource quantity necessary to execute said business application, said resource quantity being stored in a business application configuration table;

providing a usable quantity for each virtual resource, said usable quantity being stored in a resource configuration table;

providing a connectivity relation among said resources, said connectivity relation being stored in said resource configuration table; and

allocating said usable virtual resource quantity to said business application on the basis of said connectivity relation among said resources when said usable virtual resource quantity meets said resource quantity necessary for each resource.

2. The method of claim 1, wherein said dependency relation between resources is a relation for a resource to call on another resource.

3. The method of claim 2, wherein said dependency relation is based on detailed information from a section which manages said detailed information for each resource.

4. The method of claim 3, wherein said detailed information is information relating to a database used by said business application, the method further comprising:

obtaining information of a data path which said business application utilizes;

obtaining information of a storage volume from said information of said data path;

specifying an identified storage volume as a virtual resource from said information of said storage volume; and

confirming said dependency relation between said database and said storage volume.

5. A system configured to allocate a business application to a virtual resource comprising:

a management server managing said virtual resource;

a business application configuration table;

a resource configuration table;

a management information of said business application is stored in said business application configuration table; and

a configuration information is stored in said resource configuration table, said management server comprising a processing unit configured to;

provide a resource quantity necessary to execute said business application, said resource quantity being stored in a business application configuration table;

provide a usable quantity for each virtual resource, said usable quantity being stored in a resource configuration table;

providing a connectivity relation among said resources, said connectivity relation being stored in said resource configuration table; and

allocating said usable virtual resource quantity to said business application on the basis of said connectivity relation among said resources when said usable virtual resource quantity meets said resource quantity necessary for each resource.

6. The system of claim 6, wherein said dependency relation between resources is the relation for a resource to call on other resource.

7. The system of claim 6, wherein said dependency relation is based on detailed information from a section which manages said detailed information for each resource.

8. The system of claim 7, wherein said detailed information is information relating to a database used by said business application, said management server further configured to:

obtain information of a data path which said business application utilizes;

obtain information of a storage volume from said information of said data path;

specify an identified storage volume as a virtual resource from said information of said storage volume; and

confirm said dependency relation between said database and said storage volume.
