maintSpec

Purpose

Use the maintSpec subclause to specify the backup files operated on by the CHANGE, CROSSCHECK, and DELETE commands.

Syntax

maintSpec::=

Surrounding text describes maintspec.gif.

(listObjList::=, maintQualifier::=, archivelogRecordSpecifier::=, recordSpec::=, deviceSpecifier::=)

Semantics

maintSpec

Syntax Element Description
BACKUP Processes backup sets. For processing image copies, use the option COPY.

If you do not use the OF clause with CHANGE BACKUP, then RMAN changes all backup sets recorded in the repository. If you do not use the OF clause with CROSSCHECK BACKUP, then RMAN crosschecks backups of the whole database. If you do not use the OF clause with DELETE BACKUP, then RMAN deletes backups of the whole database.

   OF listObjList Restricts the list of files operated on to the object type specified in the listObjList clause.

See Also: listObjList

archivelogRecordSpecifier Processes the specified archived redo log files.

If you specify DELETE ARCHIVELOG without the BACKED UP clause, then RMAN uses the configured settings to determine whether an archived log can be deleted (CONFIGURE ARCHIVELOG DELETION POLICY TO BACKED UP). If you specify DELETE ARCHIVELOG with the BACKED UP clause, then RMAN uses the DELETE settings to determine whether an archived log can be deleted. Use FORCE with DELETE ARCHIVELOG to override a configured deletion policy as well as any mismatches between media and repository.

See Also: archivelogRecordSpecifier

COPY Processes datafile copies, control file copies, and archived redo log files.

If you do not specify an option for CHANGE COPY, then the command operates on all image copies recorded in the repository. If you are using CROSSCHECK COPY, then by default the command checks all image copies of all files in the database with status AVAILABLE or EXPIRED. If you are using DELETE COPY, then by default COPY removes copies of all files in the database. Specify the EXPIRED option to remove only copies that are marked EXPIRED in the repository.

   OF listObjList Restricts the list of objects operated on to the object type specified in the listObjList clause. If you do not specify an object, then the command defaults to all copies. Note that CHANGE COPY OF DATABASE includes datafiles but not control files.

See Also: listObjList

foreignlogRecordSpecifier Processes the specified foreign archived redo log files.

See Also: foreignlogRecordSpecifier

maintQualifier Restricts the command based on the specified options.

See Also: maintQualifier

recordSpec Specifies the file that you are performing maintenance on.

If you use the BACKUPSET parameter in recordSpec, then the keys identify backup sets for use with the CHANGE, CROSSCHECK and DELETE commands. For more details, see "LIST Command Output" for an explanation of the column headings of the LIST output tables. Use the KEY column of the output to obtain the primary key usable in the CHANGE and DELETE commands.

See Also: recordSpec

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 run CROSSCHECK...DEVICE TYPE DISK, then RMAN allocates only disk channels.

See Also: deviceSpecifier


Examples

Example 4-30 Crosschecking Backups

The following command crosschecks backups of archived redo log files:

RMAN> CROSSCHECK BACKUP OF ARCHIVELOG ALL;
 
allocated channel: ORA_SBT_TAPE_1
channel ORA_SBT_TAPE_1: SID=103 device type=SBT_TAPE
channel ORA_SBT_TAPE_1: Oracle Secure Backup
using channel ORA_DISK_1
