Disable data mask in database 11g

please provide more information:

database version

how did you implement data masking ?

.....etc

I guess you have to revoke the privileges required for running the masking process, for example:

SELECT_CATALOG_ROLE

SELECT ANY DICTIONARY

EXECUTE on SYS.DBMS_CRYPTO

remove the DM_FMTLIB package

With all this revoked from the users granted to masking should be enought in 11g

Regards

Why do you want to disable it? Just don't use it.

If the question is really "How do I see the actual data that has been masked?" then you need to have DBA role or login as sysdba, if you have masked the data using dbms_crypto.

...and when you refer to an Oracle "doc", please include the link to that doc or article so we can see what you are referring to.
