@ (at sign)

Purpose

Use the @ command to execute a series of RMAN commands stored in an operating system file with the specified path name.

Note:

The file must contain complete RMAN commands. Partial commands generate syntax errors.

Prerequisites

The command file must contain complete RMAN commands.

If you use the @ command within a RUN command, then the @ command must be on its own line (see Example 2-2).

Usage Notes

RMAN processes the file as if its contents had appeared in place of the @ command. As shown in Example 2-3, you can specify substitution variables in a command file and then pass values to the command file during execution.

Syntax

@::=

Semantics

Syntax Element Description
filename Specifies the name of a command file, for example, @/oracle/dbs/cmd/cmd1.rman. If you do not specify the absolute path name, then the current working directory is assumed, for example, @cmd1.rman.

Any file extension (or no file extension) is valid. Do not use quotes around the string or leave whitespace between the @ keyword and the file name.


Examples

Example 2-1 Running a Command File from the Operating System Command Line

This example creates an RMAN command file and then executes it from the operating system command line.

% echo "BACKUP DATABASE;" > backup_db.rman
% rman TARGET / @backup_db.rman

Example 2-2 Running a Command File Within RMAN

This example shows how you can execute a command file from the RMAN prompt and from within a RUN command. User-entered text appears in bold.

RMAN> @backup_db.rman
RMAN> RUN {
2> @backup_db.rman
3> backup database;
4> **end-of-file**
5> }

Example 2-3 Specifying Substitution Variables

Suppose that you use a text editor to create command file whole_db.rman with the following contents:

# name: whole_db.rman
BACKUP TAG &1 COPIES &2 DATABASE;
EXIT;

The following example starts RMAN from the operating system prompt and connects to the target database. The example then runs the @ command, passing variables to the command file to create two database backups with tag Q106:

% rman TARGET /
RMAN> @/tmp/whole_db.rman Q106 2
