An orchestration engine may execute multiple, concurrently running instances of a process model, where each of the instances of the process model includes one or more receiving objects. A messaging endpoint may be shared by the instances of the process model and may be configured to receive messages. A subscription handler may handle multiple subscriptions for the instances and may be configured to define a first subscription for a first instance of the multiple instances, where the first subscription includes a correlation expression, an association with the messaging endpoint, and an association with a first receiving object within the first instance. The subscription handler also may associate the first subscription with the first instance and initialize the first subscription associated with the first instance. A routing manager may route received messages that match the first subscription to the first receiving object.

Subscriptions for routing incoming messages to process instances in a process execution engine

A system may include a thread monitor that is arranged and configured to monitor progress of multiple threads of a workflow process at a synchronization point with each of the threads having a state, and configured to generate at least one inspection trigger for inspection of the threads. A thread inspector may inspect the threads at the synchronization point for a change in the state in any of the threads in response to the inspection trigger. A firing rules engine may determine whether or not the synchronization point should fire based at least in part on the change in the state of at least one of the threads.

Evaluation of synchronization gateways in process models

A system may include a gateway that is configured to intercept messages being exchanged between multiple services, a message repository that is logically coupled to the gateway and that is configured to store the intercepted messages, a service description repository that is configured to store multiple service descriptions, where each of the service descriptions corresponds to one of the services, a rules repository that is configured to store mapping rules and an adaptation engine that is configured to generate a sequence of firing rules using the service descriptions and the mapping rules responsive to the intercepted messages, to generate one or more outgoing messages in response to the intercepted messages using the sequence of firing rules, and to detect at runtime an occurrence of a termination anomaly.

Service adaptation machine

In one embodiment, the present invention includes a computer-implemented method of adapting software component interfaces by providing a user interface for specifying a provided interface, a required interface and interface operators. In another embodiment the present invention includes a computer-implemented method of adapting interfaces comprising receiving an adapter specification, receiving a plurality of communication actions from a first software component, transforming one or more of the communication actions in accordance with predefined interface operations; and sending transformed communication actions to a second software component.

Systems and methods for adapting service interface behaviors

A process model specified using, for example, UML activity diagrams can be translated into an event-based model that can be executed on top of a coordination middleware. For example, a process model may be encoded as a collection of coordinating objects that interact with each other through a coordination middleware including a shared memory space. This approach is suitable for undertaking post-deployment adaptation of process-oriented composite applications. In particular, new control dependencies can be encoded by dropping new (or enabling existing) coordinating objects into the space and/or disabling existing ones.
