CONFIGURE ARCHIVELOG DELETION POLICY CLEAR; - reset of adjustments (by default) politicians of storage of archive dens.
configure retention policy to redundancy 7; - adjustment of a policy of storage of backup copies. 7 last copies.
crosscheck archivelog all; - check of all archive dens.
delete FORCE noprompt obsolete; - removal ignoring errors of out-of-date backup copies (without acknowledgement).
delete noprompt expired archivelog all; removal of out-of-date backup copies of archive dens (without acknowledgement).
sql ' ALTER SYSTEM ARCHIVE LOG CURRENT '; - change of adjustments of archive dens - switching on a current broad gull.
backup as compressed backupset archivelog all delete input; - copying of archive dens with compression and after that to delete the copied.
