A dynamic and reactive approach to the supervision of BPEL processes
Luciano Baresi, Sam Guinea · 2008
The distributed nature of BPEL processes, the absence of a single stakeholder, the fact that partner services can dynamically change their functionality and/or QoS, and the fact we can define abstract processes and look for actual services at run-time, preclude design-time validation of such systems. We cannot assume that the cooperation between the involved parties will always play out as planned. This uncertainty requires that the interactions between the BPEL orchestrator and selected services be suitably monitored, and that recovery capabilities be available to react accordingly to unexpected events and keep the execution on track
