Abstract-With the possibility of system crashes and network failures, the design of robust client/server interactions for collaborative process execution is a challenge. If a business process changes state, it sends messages to relevant processes to inform about this change. However, server crashes and network failures may result in loss of messages. In this case, the state change is performed by one party, resulting in state/behavior inconsistencies and possibly deadlocks. Our basic idea to solve the problem is to cache the response (in a synchronous interaction) if the state of the process instance has changed by the request message. The possible state inconsistencies are recognized and compensated by state-caching and retrying failed interactions. By doing this work, we have learnt the possible failures caused by system crashes and network failures. Our results make it possible to build robust interactions by cached-based process transformations.

“…Most existing approaches provide predefined adaptation mechanisms while adding further adaptation features at run-time is not possible. The reasons for these restrictions [6] are the tight coupling of the application business logic and the adaptation features. In consequence, most approaches omit or only have a limited separate management layer for reasoning and adapting which also impacts expressiveness and flexibility of application-specific adaptation features.…”

Abstract. Smartphones and tablet PCs are on the verge of revolutionizing the information society by offering high quality applications and almost permanent connectivity to the Internet in a mobile world. They naturally support new applications that take advantage of context information like location, time and other environmental conditions. However, developing these novel context-aware applications is challenging as it is difficult to a priori anticipate their execution context and the adaptations that might be necessary to use new context information. This issue is reinforced by the semantic gap between the low-level technical realization of adaptation mechanisms and the demand to describe adaptations in abstract and comprehensible business terms. This paper presents programming support for context-aware adaptations based on a semantic model that builds on the AOCI framework. Using such a model, applications and adaptations can be described by means of easy to comprehend business terms. Thereby the model enables the AOCI framework to store and publish both context and domain-specific run-time information and provides a basis for high-level and tailored programming support. This enables to transparently select adaptations based on various criteria and integrate them into applications at run-time. At the level of adaptation mechanisms our approach supports integration for permanent changes using Aspect-Oriented Programming and more importantly for spontaneous and short-time integration of web services by means of interceptors.
