Project abstract

Self-healing software is one of the challenges for IST research. This project aims to take a step in this direction by developing a framework for self-healing Web Services.
The project will produce:

an operational framework for self-healing service execution of conversationally complex Web Services, where monitoring, detection and diagnosis of anomalous situations, due to functional or non-functional errors (e.g., Quality of Service), is carried on and repair/reconfiguration is performed, thus guaranteeing reliability and availability of Web Services;
a methodology and tools for service design that guarantee effective and efficient diagnosability/repairability during execution;
demonstration of these results on real applications.

The project started in September 2005 and it will end in February 2008. A general architecture for diagnosis and management of web services and processes to provide self-healing behaviour has been defined. A methodology and tools to provide self-healing functionality for improving data quality have been defined and a prototype for managing self-healing processes (Self-healing BPEL - SH-BPEL) has been realized. A simulator for fault injecton for testing composed cooperating web services has been realized.
