When you specify the backup or recovery operations to be performed by RMAN, you will frequently need to include several commands. If you make a mistake entering one of these commands, RMAN will abort the entire job. Because of this behavior, many DBAs use scripts containing a ready-made, correct set of RMAN commands.

You may wish to create operating system scripts containing all the commands needed to run an RMAN job, from setting the environment variables to actually backing up or restoring the database. You may also wish to create operating system scripts that pass variables to RMAN. The syntax for these scripts is the standard syntax for scripts for your operating system.

You can also create scripts to run within RMAN. The @ command calls an operating system script from within RMAN. The @@ command calls another script from within a called script. The @@ command must reference a script in the same directory as the originally called script.

You can store scripts in the recovery catalog with the following command syntax:

RMAN> script_name

You can delete a script from the catalog as follows:

RMAN> script_name
