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.
