After implementing full Oracle Data Redaction, you change the default value for the NUMBER data type as
follows:
After changing the value, you notice that FULL redaction continues to redact numeric data with zero.
What must you do to activate the new default value for numeric full redaction?
A.
Re-enable redaction policies that use FULL data redaction.
B.
Re-create redaction policies that use FULL data redaction.
C.
Re-connect the sessions that access objects with redaction policies defined on them.
D.
Flush the shared pool.
E.
Restart the database instance.
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.
Note:
* The DBMS_REDACT package provides an interface to Oracle Data Redaction, which enables you to mask
(redact) data that is returned from queries issued by low-privileged users or an application.
* UPDATE_FULL_REDACTION_VALUES Procedure
This procedure modifies the default displayed values for a Data Redaction policy for full redaction.* After you create the Data Redaction policy, it is automatically enabled and ready to redact data.
* Oracle Data Redaction enables you to mask (redact) data that is returned from queries issued by lowprivileged users or applications. You can redact column data by using one of the following methods:
/ Full redaction.
/ Partial redaction.
/ Regular expressions.
/ Random redaction.
/ No redaction.
