A Novel Approach for Web Service Run Time Exception Handling

Abstract

Service Computing has recently gained significant momentum to enable the IT services and computing technology to perform business services more efficiently and effectively. Runtime management has been given utmost significance as a potential strategy to handle runtime exceptions increases the adaptability of services to exceptional circumstances. service computing aims for efficiently handling run time issues during service computation such as exception handling, change management and dynamic reconfigurable services. There are many exceptions often raised during service consumption and execution at run time and some of them gets resolved, but many of them failed to resolve due to the lack of run time exception handling mechanism. In this paper we propose a model for context aware web service exception handling targeting service life time and service reaction time which could determine whether the exception is solvable or un solvable with respect to the exception context with time and policy constraints. Thus a novel approach for web service runtime exception handling has been proposed which affords facilities for managing the runtime exception with the help of a set of QoS parameters that are satisfying the service computational criteria such as computability, traceability, and decidability. In addition to that, it supports serviceability, manageability, availability and configurability. The results encourage new direction of research with performance upgrade in the field of service computing for runtime exception handling.
