4.18 recordSpec

Purpose

Use the recordSpec subclause to specify which backups or copies the CHANGE, CROSSCHECK, DELETE, and LIST commands process.

Most recordSpec options allow you to specify a primary key. Use the output of the LIST command to obtain primary keys.

Syntax

recordSpec::=

Description of the illustration recordspec.eps

Semantics

Syntax Element	Description
ARCHIVELOG	Specifies an archived redo log by either primary key or file name.
BACKUPSET	Specifies a backup set by primary key.
BACKUPPIECE	Specifies a backup piece by media handle, primary key, or tag name.
PROXY	Specifies a proxy copy by media handle, primary key, or tag name.
CONTROLFILECOPY	Specifies a control file copy by primary key, file name pattern ('filename'), or TAG tag_name. If you crosscheck a control file copy, then you must specify a file name rather than a primary key.
DATAFILECOPY	Specifies a data file copy by primary key, file name pattern ('filename'), tag (TAG tag_name), or matching string (LIKE 'string_pattern'). Specify ALL to indicate all data file copies recorded in the RMAN repository.
NODUPLICATES	Targets only one copy of the control file or data file copy for the operation, even when there are multiple copies.
