Explanation:
About Stored Scripts
You can use a stored script as an alternative to a command file for managing frequently used sequences of
RMAN commands. The script is stored in the recovery catalog rather than on the file system.
Stored scripts can be local or global. A local script is associated with the target database to which RMAN is
connected when the script is created, and can only be executed when you are connected to that target
database. A global stored script can be run against any database registered in the recovery catalog, if the
RMAN client is connected to the recovery catalog and a target database.
The commands allowable within the brackets of the CREATE SCRIPT command are the same commands
supported within a RUN block. Any command that is legal within a RUN command is permitted in the stored
script. The following commands are not legal within stored scripts: RUN, @, and @@.
When specifying a script name, RMAN permits but generally does not require that you use quotes around the
name of a stored script. If the name begins with a digit or is an RMAN reserved word, however, then you must
put quotes around the name to use it as a stored script name. Consider avoiding stored script names that begin
with nonalphabetic characters or that are the same as RMAN reserved words.
