The Impact of Service Semantics on the Consistent Recovery in SOA

This paper addresses a problem of consistent recovery of SOA processing. So far, the recovered state was considered as consistent if all events that have occurred before the failure were transparently recovered. However, providing such a strict consistency introduces a high performance overhead. Thus, we propose the semantic-based classification of services that enables to slack the notion of consistent recovered state from the viewpoint of services. We also present the extension of RESERVE rollback-recovery protocol that guarantees the proposed relaxed recovery consistency.
