4.15 maintQualifier


Use the maintQualifier subclause to specify database files and archived redo log files.



Syntax Element Description


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 data file copies by specifying a file name 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.

GUID guid_name

Specifies the GUID of the pluggable database (PDB) on which the specified action is performed. Each PDB is identified using a unique GUID. You can determine the GUID of a dropped PDB by querying the dba_pdb_history view.

BACKED UP integer TIMES TO DEVICE TYPE deviceSpecifier

Restricts the command to archived logs and backup sets that have been successfully backed up integer or more times to the specified media.

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 is overridden. Use FORCE with DELETE ARCHIVELOG to override this configuration and any mismatches between media and repository.

TAG tag_name

Specifies the data file 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 file name format for tags


Example 4-30 Listing Backups in a Specific Location

The following command lists all image copies located in directory /disk2:

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

Example 4-31 Deleting Archived Logs That Are 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.

released channel: ORA_SBT_TAPE_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=104 device type=DISK
