(A) partial reloading mechanism for database recovery

Abstract

This thesis is concerned with a mechanism for reloading a partial database to maintain a consistent database state when a failure occurs. The mechanism is based on the reload graph technique which uses a portion of database rather than the whole. It can also eliminate useless edges in a reload graph by obtaining minimum dump set. Through the optimized reload graph from the process of the construction of the graph, the system can maintain minimum dumps of database. A possible implementation of the reloading mechanism is presented and simulated by using CROMEMCO system Three.
