Explanation: ALL is an optional parameter specifying that all functions controlled by this command, except logging, are prevented.
If the EOD or EOV parameter is specified, then all functions (except ABACKUP, ARECOVER, FRBACKUP, and FRRECOV) are held using that parameter. If neither EOD nor EOV is specified, then each function is held according to its default: BACKUP, MIGRATION, and RECOVER are held as EOD, and DUMP is held as EOV. ABACKUP and ARECOVER ignore the EOD parameter.
Defaults: None.
