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::=

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.
