Fault Tolerant Web Service Orchestration by Means of Diagnosis
نویسندگان
چکیده
Web Service orchestration frameworks support a coarse-grained kind of exception handling because they cannot identify the causes of the occurring exceptions as precisely as needed to solve problems at their origin. This paper presents a framework for Web Service orchestration which employs diagnostic services to support a fine grained identification of the causes of the exceptions and the consequent execution of effective exception handlers. Our framework is particularly suitable for intelligent exception handling in Enterprise Application Integration.

Architectural Plan for Constructing Fault Tolerable Workflow Engines Based on Grid Service
In this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. The engines are assumed to be implemented as composite web services. Current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. The difficulty is to rollback the execution state of the workflo...

متن کاملFT-Net Traveler: Fault-Tolerant and Scalable Web Service Broker Architecture
Web services are becoming the ultimate response for organizations and companies offering their core business services over the Internet. In fact, those business services are being offered through Web services which act like APIs providing the logic to handle a business service. Although, some Web services do not require other Web services to accomplish their tasks, the most interesting ones do ...
متن کاملFault Diagnosis and Fault-Tolerant SVPWM Technique of Six-phase Converter under Open-Switch Fault
In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...
متن کاملA Runtime Dependability Evaluation Framework for Fault Tolerant Web Services
Service-oriented systems are usually built on top of Web service components, which are distributed across the Internet, making dependability a big challenge. In this paper, we propose a runtime dependability evaluation framework for fault tolerant Web services to attack this crucial problem. We first propose a user-collaborative framework for collecting Web service QoS information from both the...
