Abstract

Nowadays eager update everywhere replication protocols are widely proposed for replicated databases. They work together with recovery protocols in order to provide highly available and fault-tolerant information systems. This paper proposes two enhancements for reducing the recovery times, minimizing the recovery information to transfer. The idea is to consider on one hand a more realistic failure model scenario –crash recovery with partial amnesia– and on the other hand to apply a compacting technique. Moreover, it is provided amnesia support avoiding possible state inconsistencies –associated to the failure model assumed– before starting the recovery process at recovering replicas.
