The backup policy of Oracle OLAP
Abstract:Data is the most important resource. The security of data depends on the safety of database performance. For the high availability database, backup is vital. In this paper, we present a formulation of backup based on Better Life Commercial Chain Share Co.,Ltd'Oracle 10g Warehouse Builder of the Linux platform.The formulation combines the logic backup with physical backup and incremental backup, ZLIB algorithm, in the OLAP environment.The simulation results that the proposed formulation is safety,efficiency and fast.Both the backup strategy and implement steps are described in details.
