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.
