Oracle's database operations are recorded in the redo log for undo (rollback) or redo (redo) at the time of the database exception. Redo log is also divided into online (online log) and archive (archive log) two parts.Oracle has 3 online log files by default, usually written in sequential order with one and the next, while full online log files are organized into archived logs.
