Techniques are presented for dynamically adapting software components. An enhancement for a component is dynamically detected and installed. The enhancement is dynamically processed for requests directed to the component or for responses generated by the component.

Adaptive software component techniques

A distributed computer system in several embodiments includes several architectures or configurations. Each configuration exhibits a different degree of coupling between an application that provides data and an application that consumes that data. In an embodiment, a provider application knows the identity of a consumer application, converts data into the format of the consumer application, and transmits the data to the consumer application. In other embodiments, the provider application does not know the identity of the consumer application, and transmits data to the consumer application through an intermediary. In such embodiments, either the provider or the intermediary can perform the data conversion. In another embodiment, a manager object oversees the transformation of the system from one configuration to another in real time.

Distributed system architecture for variable coupling

A technique for facilitating coordination of actions by multiple programs involves providing an execution environment for active objects. The execution environment may be an object space. Client programs may write active objects to the object space, which execute on behalf of the client programs. The client programs may obtain the results of the executed active objects, even if the client program is disconnected from the object space while the active object is executing.
