1. þ A, D, and E. Using a recovery catalog allows you to create and maintain

stored scripts. In addition, it keeps a running history of all changes to the

database tablespaces and datafiles because the recovery catalog was created.

Finally, you can store recovery information for more than one database in a

recovery catalog.

ý B and C. B is not a good reason to use a recovery catalog because the

RMAN repository information is always stored in the controlfile even if

you use a recovery catalog. C is also not a good reason, because a recovery

catalog requires more setup and maintenance in addition to a backup of

another database. Also, the controlfile is simpler to manage, and its size can

be controlled with the parameter CONTROL_FILE_RECORD_KEEP_TIME.

It is much simpler to export a copy of the controlfile whenever the database

structure changes using ALTER DATABASE BACKUP CONTROLFILE TO

TRACE.
