How can a user test the redaction policies defined in Oracle Data Redaction?

The correct approach to test the redaction policies defined in Oracle Data Redaction is by using the None redaction type option. This method allows users to evaluate the impact of redaction policies without altering the actual data being displayed.

When the None redaction type is applied, it effectively means that no redaction will occur on the data, permitting users to see the original values. This is invaluable for debugging and validating the logic of the redaction policies. It enables users to understand how their policies are functioning, ensuring that they will redact the correct data when the policies are activated.

This approach is particularly useful in a controlled environment where one would want to assess the intended effects of the redaction policies or test the performance implications without compromising data security or integrity. In contrast, implementing redaction policies directly in production could lead to unforeseen consequences, and manually querying to assess performance does not provide an accurate depiction of how redaction policies will work in practice. Adjusting data types is unrelated to testing the redaction policies themselves but would be more relevant in defining policy applicability across different data types.
