How to Wipe a Datafile that had Sensitive Information

edited Sep 8, 2020 9:31PM in Database Administration (MOSC) 2 commentsAnswered

I have a tablespace that contains sensitive data that can not be exposed.  If I drop the tablespace I need to be able to wipe the datafiles.  Is there an Oracle way to do this ideally with the NIST SP-800-88r1 media sanitation standard in mind ???

We are already using TDE (transparent data encryption) on the the tablespace and encrypted backups with RMAN.

The platform is Linux and Oracle 12c.

Thanks,

Alan
