Demo Questions

Your database is running in archivelog mode and a nightly backup of the database, along with an autobackup of the control file, is taken by using RMAN. Because of a media failure, the SPFILE and the control files are lost.

Examine the steps to restore the SPFILE and the control file to mount the database:

Set DBID of the target database in RMAN.
Start the database instance by using the startup force nomount command in RMAN.
Restore the control files from the backup.
Mount the database.
Restore the SPFILE from the autobackup.
Create a PFILE from the recovered SPFILE.
Restart the instance in nomount state.

Identify the required steps in the correct order.

Correct answer: C

After implementing full Oracle Data Redaction, you change the default value for the number data type as follows:

SQL> SELECT NUMBER_VALUE FROM REDACTION_VALUES_FOR_TYPE_FULL; NUMBER_VALUE

-------------------------

SQL> EXEC DBMS_REDACT.UPDATE_FULL_REDACTI0N_VALUES(-1)

PL/SQL procedure successfully completed.

SQL> select number_value from redaction_values_for_type_full;

NUMBER VALUE

------------------------

-1

After changing the value, you notice that FULL redaction continues to redact numeric data with a zero.

What must you do to activate the new default value for numeric full redaction?

Re-enable redaction policies that use FULL data redaction.
Re-create redaction policies that use FULL data redaction.
Re-connect the sessions that access objects with redaction policies defined on them.
Flush the shared pool.
Restart the database instance.

Correct answer: E

Explanation:

About Altering the Default Full Data Redaction Value You can alter the default displayed values for full Data Redaction polices. By default, 0 is the redacted value when Oracle Database performs full redaction (DBMS_REDACT.FULL) on a column of the NUMBER data type. If you want to change it to another value (for example, 7), then you can run the DBMS_REDACT.UPDATE_FULL_REDACTION_VALUES procedure to modify this value. The modification applies to all of the Data Redaction policies in the current database instance. After you modify a value, you must restart the database for it to take effect.

You want to create a guaranteed restore point for your database by executing the command:

SQL> CREATE RESTORE POINT dbrsp1 GUARANTEE FLASHBACK DATABASE;

Identify two prerequisites for the successful execution of this command. (Choose two.)
