Abstract

An operation managing apparatus totalizes necessary resource amount information every the service so as to acquire necessary resource amount information every BP, and identifies the necessary resource amount information every the BP with resource amount information which can be utilized with respect to each of the service executing apparatuses so as to retrieve such service executing apparatuses capable of providing resource amounts by which the necessary resource amount information every the BP is stored. When the service executing apparatuses are retrieved, the operation managing apparatus allocates a service to the retrieved service executing apparatuses, whereas when the service executing apparatuses are not retrieved, the operation managing apparatus allocates the services to plural sets of the service executing apparatuses.

Claims

1. A resource allocating method executed in a BP (Business Process) processing system arranged by comprising:

a BP executing apparatus for executing activities of BPs (Business Processes);

a plurality of service executing apparatuses for executing services which are called by said activities; and

an operation managing apparatus for managing resources of said service executing apparatuses, which correspond to resources of physical computers utilized by said services to be executed, wherein;

said operation managing apparatus reads out correspondence information between the activities of the BPs and the services called by said activities, necessary resource amount information for each of the called services, and resource amount information which can be utilized every said service executing apparatus from a storage unit;

said operation managing apparatus totalizes necessary resource amount information every said service so as to acquire necessary resource amount information every said BP, and identifies the necessary resource amount information every said BP with resource amount information which can be utilized with respect to each of said service executing apparatuses so as to retrieve such service executing apparatuses capable of providing resource amounts by which the necessary resource amount information every said BP is stored;

when said service executing apparatuses are retrieved, the operation managing apparatus allocates a service which is called from an activity belonging to the same BP with respect to a resource of one set of said service executing apparatus from said retrieved service executing apparatuses;

when said service executing apparatuses are not retrieved, said operation managing apparatus allocates said services to plural sets of said service executing apparatuses by repeatedly performing a process operation in which the operation managing apparatus selects the services called from the activities of the BPs in the order from a service having a larger necessary resource amount, selects the service executing apparatuses in the order from a service executing apparatus having a larger providable resource amount, and allocates the selected service to the selected service executing apparatus.

2. A resource allocating method as claimed in claim 1 wherein:

in a step for allocating said services to one set of said service executing apparatuses, the services are allocated with respect to such a service executing apparatus whose providable resource amount is the largest resource amount among said retrieved service executing apparatuses.

3. A resource allocating method as claimed in claim 1 wherein:

in a step for allocating said services to one set of said service executing apparatuses, the services are allocated with respect to such a service executing apparatus whose providable resource amount is the smallest resource amount among said retrieved service executing apparatuses.

4. A resource allocating method as claimed in claim 1, wherein:

said operation managing apparatus further controls that a power supply of such a service executing apparatus is turned OFF to which the services have not been allocated as a result of the step for allocating said services.

5. A resource allocating method as claimed in claim 1 wherein:

when said operation managing apparatus further senses such an event that a load is increased which is given to the services allocated to one set of said service executing apparatus after a step for allocating said services, the operation managing apparatus once cancels the allocation as to the services called from the BP which calls the services whose load is increased, and thereafter, allocates the services with respect to the plural sets of said service executing apparatuses.

6. A resource allocating method as claimed in claim 1, wherein:

when said operation managing apparatus further senses such an event that a load is decreased which is given to the services allocated to plural sets of said service executing apparatuses after a step for allocating said services, the operation managing apparatus once cancels the allocation as to the services called from the BP which calls the services whose load is decreased, and thereafter, allocates the services with respect to one set of said service executing apparatus.

7. A resource allocating method as claimed in claim 1, wherein:

when said operation managing apparatus further senses that a structure of a BP has been changed which calls the allocated services after a step for allocating said services, said operation managing apparatus judges whether or not such a service which is called by an activity additionally provided due to the structural change can be allocated with respect to said service executing apparatus to which the services called by the structural-changed BP have been allocated;

if said service can be allocated thereto, then said operation managing apparatus adds the service called by the activity added with respect to said service executing apparatus;

if said service cannot be allocated thereto, then said operation managing apparatus once cancels the allocation of the services called by the structural-changed BP, and thereafter, allocates said services with respect to the plural sets of said service executing apparatus.

8. A resource allocation program for causing a computer to execute the resource allocating method recited in claim 1.

9. An operation managing apparatus employed in a BP (Business Process) processing system arranged by comprising:

a BP executing apparatus for executing activities of BPs (Business Process);

a plurality of service executing apparatuses for executing services which are called by said activities; and

said operation managing apparatus for managing resources of said service executing apparatuses, which correspond to resources of physical computers utilized by said services to be executed, wherein;

said operation managing apparatus is comprised of;

a storage unit; and

an allocation scheming unit; and

wherein;

said storage unit stores thereinto correspondence information between the activities of the BPs and the services called by said activities, necessary resource amount information for each of the called services, and resource amount information which can be utilized every said service executing apparatus;

said allocation scheming unit totalizes necessary resource amount information every said service so as to acquire necessary resource amount information every said BP, and identifies the necessary resource amount information every said BP with resource amount information which can be utilized with respect to each of said service executing apparatuses so as to retrieve such service executing apparatuses capable of providing resource amounts by which the necessary resource amount information every said BP is stored;

when said service executing apparatuses are retrieved, the allocation scheming unit allocates a service which is called from an activity belonging to the same BP with respect to a resource of one set of said service executing apparatus from said retrieved service executing apparatuses;

when said service executing apparatuses are not retrieved, said allocation scheming unit allocates said services to plural sets of said service executing apparatuses by repeatedly performing a process operation in which the allocation scheming unit selects the services called from the activities of the BPs in the order from a service having a larger necessary resource amount, selects the service executing apparatuses in the order from a service executing apparatus having a larger providable resource amount, and allocates the selected service to the selected service executing apparatus.
