recordSpec

Purpose

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

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

Syntax

Semantics

Syntax Element	Description
`ARCHIVELOG`	Specifies an archived redo log by either primary key or filename.
`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, filename pattern (`'filename'`), or `TAG` `tag_name`. If you crosscheck a control file copy, then you must specify a filename rather than a primary key.
`DATAFILECOPY`	Specifies a datafile copy by primary key, filename pattern (`'filename'`), tag (`TAG` `tag_name`), or matching string (`LIKE 'string_pattern'`). Specify `ALL` to indicate all datafile copies recorded in the RMAN repository.
`NODUPLICATES`	Specifies that only one copy of the control file or datafile copy specified by the rest of the clause should be the target of the operation, even when there are multiple copies.
