Abstract

The ability to adapt running process instances is a key requirement to handle exceptions in service orchestrations. The design of the orchestration
middleware and its underlying meta-model plays an important role to fulfill this requirement. However, current service orchestration middleware such as BPEL engines suffer from their imperative and tightly coupled task execution mechanisms making it difficult to adapt running process instances. In this paper we present a novel service orchestration middleware and its underlying meta-model to overcome this limitation. To achieve this, we combine the benefits of the models@runtime concept with the event-driven publish-subscribe mechanism. We evaluate our approach for its support to process instance adaptation and compare its performance to an existing orchestration runtime.
