Semantics

maintQualifier

Syntax Element	Description
`completedTimeSpec`	Specifies a range of time for completion of the backup or copy. See Also: `completedTimeSpec`
`DEVICE` `TYPE` `deviceSpecifier`	Allocates automatic channels for the specified device type only. This option is valid only if you have configured automatic channels and have not manually allocated channels. For example, if you configure automatic disk and tape channels, and issue `CHANGE...DEVICE` `TYPE` `DISK`, then RMAN allocates only disk channels. See Also: `deviceSpecifier`
`LIKE` `'string_pattern'`	Restricts datafile copies by specifying a filename pattern. The pattern can contain Oracle pattern matching characters percent sign (`%`) and underscore (`_`). RMAN only operates on those files whose name matches the pattern. Note: You cannot use the `LIKE` option with the `LIST` `...` `ARCHIVELOG` command or with backup pieces.
`BACKED` `UP` `integer` `TIMES` `TO` `DEVICE` `TYPE` `deviceSpecifier`	Restricts the command to archived logs that have been successfully backed up `integer` or more times to the specified media. This option applies only to archived redo logs. When the `BACKED UP` option is used with the `DELETE` `ARCHIVELOG` command, RMAN uses the `BACKED UP` setting rather than the configured settings to determine whether an archived log can be deleted. That is, `CONFIGURE` `ARCHIVELOG DELETION POLICY TO BACKED UP` is overridden. Use `FORCE` with `DELETE ARCHIVELOG` to override this configuration as well as any mismatches between media and repository.
`TAG` `tag_name`	Specifies the datafile copies and backup sets by tag. Tag names are not case sensitive and display in all uppercase. See Also: `BACKUP` for a description of how a tag can be applied to an individual copy of a duplexed backup set, and also for a description of the default filename format for tags

Example

Example 3-28 Listing Backups in a Specific Location

The following command lists all image copies located in /disk1:

RMAN> LIST COPY LIKE '/disk2/%';

Example 3-29 Deleting Archived Logs That Are Already Backed Up

The following command deletes only those archived logs that have been successfully backed up two or more times to tape. In this example, only the sequence 36 archived log meets these criteria.

RMAN> DELETE ARCHIVELOG ALL BACKED UP 2 TIMES TO DEVICE TYPE sbt;
 
released channel: ORA_SBT_TAPE_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=104 device type=DISK
