Methods, systems, and computer program products for aggregating service components in a data processing system according to predefined aggregation rules. The method includes providing a plurality of visual elements, each visual element representing a corresponding service component; selecting a new visual element for addition to an aggregation structure; determining a set of eligible visual elements of eligible service components among the instantiated service components; associating a visual cue with the eligible visual elements; and aggregating the new service component to a selected eligible service component in the aggregation structure. The new service component is compatible for aggregation with each eligible service component according to the aggregation rules. The aggregation structure includes an aggregation of instantiated visual elements of instantiated service components to define an aggregated service according to the aggregation of the instantiated service components.

Aggregating service components

A solution for metering usage of services&#x2014;for example, in a SOA Framework&#x2014;is proposed. For this purpose, the submission of any invocation of a provider service by a consumer service is intercepted by a license manager; a corresponding request is then submitted to a dedicated licensing service, which returns an entitlement code when the consumer service is entitled to submit the service invocation. The service invocation is decorated with this entitlement code and actually submitted to the provider service. The (decorated) service invocation addressed to the provider service is likewise intercepted by another license manager; a request is then submitted to the licensing service for verifying the received entitlement code. The running of the provider service is then enabled only if the entitlement code is correct.

Meeting usage of services in a environment

A mechanism is provided for implementing an adaptive model. The mechanism allows an authority to define a desired target state of several kinds of resources, which are directly controlled by different subjects. The authority publishes 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 the rules corresponding to its logic category from the shared repository. The rules are then applied 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.

Resource management with rule based consistency check

A resource management method () 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 () a series of rules in a shared repository; each rule indicates the target state of a resource for a corresponding category of the subjects. Each subject retrieves (--) the rules corresponding to its category from the shared repository. The rules are then applied () by the subject directly. In this way, the subjects self-adapt to the rules, without requiring any direct interaction with the authority.

The helper then enforces () application of the rules on the subject. In this way, the subjects adapt to the rules without requiring any direct interaction with the authority, even if they do not have the necessary computational power required to be completely autonomous.
