QUESTION 86
What is the purpose of the RMAN recovery catalog? (Choose all that apply.)
A. Make backups faster
B. Store RMAN metadata
C. Store RMAN scripts
D. Provide the ability to do centralized backup reporting.
E. Make recovery faster
Answer: BCD
Explanation:
A recovery catalog is a database schema used by RMAN to store metadata about one or more Oracle databases. Typically, you store the catalog in a dedicated database. A recovery catalog provides the following benefits:
A recovery catalog creates redundancy for the RMAN repository stored in the control file of each target database. The recovery catalog serves as a secondary metadata repository. If the target control file and all backups are lost, then the RMAN metadata still exists in the recovery catalog.
A recovery catalog centralizes metadata for all your target databases. Storing the metadata in a single place makes reporting and administration tasks easier to perform.
A recovery catalog can store metadata history much longer than the control file. This capability is useful if you must do a recovery that goes further back in time than the history in the control file. The added complexity of managing a recovery catalog database can be offset by the convenience of having the extended backup history available.
Some RMAN features function only when you use a recovery catalog. For example, you can store RMAN scripts in a recovery catalog. The chief advantage of a stored script is that it is available to any RMAN client that can connect to the target database and recovery catalog. Command files are only available if the RMAN client has access to the file system on which they are stored.
A recovery catalog is required when you use RMAN in a Data Guard environment. By storing backup metadata for all primary and standby databases, the catalog enables you to offload backup tasks to one standby database while enabling you to restore backups on other databases in the environment.
QUESTION 87
RMAN provides more granular catalog security through which feature?
A. Virtual private database
B. Virtual private catalog
C. RMAN virtual database
D. RMAN secure catalog
E. Oracle Database Vault
Answer: B
Explanation:
About Virtual Private Catalogs
By default, all of the users of an RMAN recovery catalog have full privileges to insert, update, and delete any metadata in the catalog. For example, if the administrators of two unrelated databases share the same recovery catalog, each administrator could, whether inadvertently or maliciously, destroy catalog data for the other’s database. In many enterprises, this situation is tolerated because the same people manage many different databases and also manage the recovery catalog. But in other enterprises where clear separation of duty exists between administrators of various databases, and between the DBA and the administrator of the recovery catalog, you may desire to restrict each database administrator to modify only backup metadata belonging to those databases that they are responsible for, while still keeping the benefits of a single, centrallymanaged, RMAN recovery catalog. This goal can be achieved by implementing virtual private catalogs.
QUESTION 88
You can back up the RMAN recovery catalog with RMAN.
A. True
B. False
Answer: A
Explanation:
When backing up the recovery catalog database, you can use RMAN to make the backups.

QUESTION 89
What RMAN command must you use before you can back up a database using the recovery catalog?
A. create catalog
B. install database
C. catalog database
D. merge Catalog with database
E. register database
Answer: E
