Abstract

Recovery of a database system can be initiated by taking the database system offline. Thereafter, recovery operations specified by a redo log of the database system are replayed. During the replaying, updates to pages implicated by the recovery operations are blocked. In parallel, modified pages are flushed to physical disk storage. The database is later brought online after all of the recovery operations are replayed.
