Fault Tolerant Web Service Orchestration by Means of Diagnosis

Abstract

Abstract. 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.

An Approach to Web Service Faults Diagnosis Based on Conditional Random Fields

“…The local diagnosis component tried to explain the fault and then reported the interpretation to global diagnosis component. Later, Ardissono extended their work [14]. Ardissono appended a fault repair component which was used to repair fault according to the interpretation.…”

Maintenance Research in SOA - Towards a Standard Case Study

“…From this selection of papers we noticed that some authors created their own simple non-industrial examples as case systems, which contain a very small number of services, e.g., [11] and [14] have one and three services respectively. It is arguable whether these small case study systems are representative of real servicebased software systems.…”

“…Guidi et al [7] regard synchronous invoke activities: they propose to wait for the reply message regardless of faults in parallel branches in the process before executing the termination handler. Ardissono et al [8] shows how hypothesis about the cause of a fault can be constructed and how this information can be used in business processes. Friedrich at al.…”
