Detection and resolution of atomicity violation in service composition

Atomicity is a desirable property that safeguards application consistency for service compositions. A service composition exhibiting this property could either complete or cancel itself without any side effects. It is possible to achieve this property for a service composition by selecting suitable web services to form an atomicity sphere. However, this property might still be breached at runtime due to the interference between various service compositions caused by implicit interactions. Existing approaches to addressing this problem by restricting concurrent execution of services to avoid all implicit interactions however compromise the performance of service compositions due to the long running nature of web services. In this paper, we propose a novel static approach to analyzing the implicit interactions a web service may interfere and their impacts on the atomicity property in each of its service compositions. By locating afflicted implicit interactions in a service composition, ...
