RMAN>
The database is now open and available for use. RMAN will pick the most efficient way to
perform the requested operation, minimizing the number of files accessed or the number of disk I/
Os to bring the database back to a consistent state in as short a time as possible. In the previous
example, RMAN used a full database backupset and archived redo log files to recover the database.
During a recovery operation, RMAN may need to restore archived redo logs from tape; to
limit the amount of disk space used during a recovery operation, the recover command used in
the previous example could use the following options instead:
RMAN> recover database delete archivelog maxsize 2gb;
The parameter delete archivelog directs RMAN to remove archived log files from disk that
were restored from tape for this recovery option; the maxsize 2gb parameter restricts the amount
of space that can be occupied by restored archived log files at any point in time to 2GB.
