Explanation/Reference:
Section: Backup, Recovery & Recovery Manager (RMAN)
To create and execute an RMAN stored script, you must use a recovery catalog because RMAN stored scripts
are stored in the recovery catalog. You cannot use RMAN stored scripts if you are using the control filefor your
RMAN repository.
The option that states when executing a stored script and a command fails, the remainder of the scriptis
executed, and a message is written to the alert logfile is incorrect. If you are executing a stored RMAN script
and one of the commands in the script fails, the other subsequent commands in the script are not executed
because a stored RMAN script is created within a RUNblock.
The option that states RMAN stored scripts can always be executed against any target database that is
registered in the recovery catalog is incorrect. RMAN stored scripts can be created as local scripts oras global
scripts. Local scripts can only be executed againstthe target database to which you are connected when you
create the script. To create a global script that can be executed against any target database registered in the
recovery catalog, you must include the GLOBAL keywordwhen you create the script.
The option that states when you execute a stored script, it always executes using the persistent channel
settings set with the CONFIGURE command is incorrect. You can override any persistent channel settings by
including an ALLOCATE CHANNEL command in the RUN block before executing the script.
