deviceSpecifier

Syntax

Text description of the illustration devicesp.gif

Purpose

A subclause specifying the type of storage for a backup or copy.

Keywords and Parameters

DISK

Specifies disk storage.

'media_device'

Specifies a sequential I/O device or access method for storage. The syntax and semantics of sequential I/O device types are platform-specific. Example values are sbt and sbt_tape (with or without quotes). These values are synonymous. The media_device variable specifies a media management device such as a third-party tape subsystem interface. Note that media device names are not case sensitive. The sbt variable is legal as input, but RMAN output always displays its synonym sbt_tape. It is stored in the catalog as sbt_tape for backwards compatibility.

}
