Abstract
A resource management method (400c) and a corresponding system implementing an adaptive model are proposed. The method allows an authority to define a desired target state of several kinds of resources, which are directly controlled by different subjects. The authority publishes (460) a series of rules in a shared repository; each rule indicates the target state of a resource for a corresponding logic or physic category of the subjects. Each subject retrieves (444-456;462-468) the rules corresponding to its logic category from the shared repository. The rules are then applied (458;469) by the subject; as a result, the physic category of the subject is updated. The subject now retrieves and applies the rules corresponding to its physic category. In this way, different dependency schemes may be implemented without any explicit definition in the rules.

8. A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program, when executed in a data processing system including a plurality of subject entities and at least one authority entity, performs a resource management method for consistently self-configuring a subject entity within the plurality of subject entities when the computer readable program is run on a computer of the subject entity, wherein each subject entity in the plurality of subject entities controls an instance of at least one resource and belongs to at least one logic category of a plurality of logic categories and to at least one physic category of a plurality of physic categories, the at least one authority entity defining a target state of the at least one resource by publishing a plurality of rules, at least one rule of the plurality of rules including an indication of the target state of the at least one resource for the at least one logic category of each subject entity and at least a further rule of the plurality of rules including the indication of the target state of the resource for the at least one physic category of each subject entity, and for each subject entity:
-
determining if a current state of the at least one resource on the subject entity corresponds to the target state;
responsive to the current state failing to correspond to the target state, enforcing a management action to bring the current state of the at least one resource to the target state;
responsive to the current state corresponding to the target state, retrieving a first set of rules from the plurality of rules corresponding to the at least one logic category of the subject entity;
configuring each subject entity according to the target state by applying the first set of rules;
retrieving a second set of rules corresponding to the at least one physic category of each subject entity; and
configuring the subject entity according to the target state by applying the second set of rules. - View Dependent Claims (11, 12, 13, 14)
