Abstract
The invention provides a method for fault handling in a co-operative workflow environment that employs a placement strategy for transaction scope and associated fault handlers and compensation handlers across different workfiow components. The method employs a fault propagation scheme for forwarding a fault occurring in any of the workflow components to a fault handler. The method employs a distributed data collection mechanism to facilitate recovery from a fault occurring in any the workfiow components. The method employs a fault recovery mechanism using compensation. The transaction scope defines a transaction boundary and provides a fault handling and a fault recovery context for a set of activities and the transaction scope may be nested inside another transaction scope resulting in outer and inner scopes.
