Oracle TDE 12.1.0.2: Encrypting the system table spaces and column in the system tables

edited Feb 1, 2020 10:43PM in Database Security Products (MOSC) 1 commentAnswered ✓

Hi,

  1. Is it possible to encrypt the system table spaces using TDE in "ORACLE 12.1.0.2"
  2. Is it possible to encrypt individual columns in the tables in system tablespace using TDE in "ORACLE 12.1.0.2" ?

Here is the reason why I am asking. In Oracle 12.2, if the system tablespace  in multitenant container database (CDB) is encrypted with TDE, then the database cannot be started directly. Below are the steps to start the database when system tablespace is encrypted.

  1. Open the CDB in the mount mode
  2. Open the TDE keystore
  3. Open the CDB database.

I am trying to understand, in Oracle 12.1.0.2 during the startup, would there ever be a need to start the CDB in the mount mode, open the TDE keystores and then continue with open of the database ?
