TDE 与 RAC 测试

How to configure TDE in pluggable database in 12c for standalone and RAC environment (Doc ID 2107821.1)

This document details step by step instructions to configure TDE in 12c pluggable database for standalone and RAC environment.

1. Add the below entry in sqlnet.ora file

1
2
3
4
5
6
ENCRYPTION_WALLET_LOCATION =
      (SOURCE = (METHOD = FILE)
          (METHOD_DATA =
               (DIRECTORY = /cdbrdbms/etc/$ORACLE_SID)
          )
      )

2. Create Key store on CDB database and generate encryption key for CDB

1
2
3
ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '/cdbrdbms/etc/MTc12c1' IDENTIFIED BY "welcome1";
ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY "welcome1";
ADMINISTER KEY MANAGEMENT SET KEY IDENTIFIED BY "welcome1" WITH BACKUP;

3. Verify the wallet has been opened in CDB database

select * from v$encryption_wallet;

STATUS WALLET_TYPE WALLET_OR FULLY_BAC
------------------------------ -------------------- --------- ---------
CON_ID
----------
FILE
/cdbrdbms/etc/MTc12c1/
OPEN PASSWORD SINGLE NO
0

4. Open the respective PDB and set the PDB as current database

4 MTC12P2 MOUNTED

SQL> alter pluggable database MTC12P2 open;

Pluggable database altered.

SQL> show pdbs

SQL> alter session set container=MTC12P2;

Session altered.

SQL> show con_name

MTC12P2

5. Open the keystore in that PDB and generate encryption key for the PDB

4 MTC12P2 READ WRITE NO


SQL> create tablespace enc128_ts
datafile '/cdbrdbms/64bit/app/oracle/oradata/MTc12c1/MTc12p2/Test_encrption.dbf'
size 1M autoextend on next 1M
encryption using 'AES128'
default storage (encrypt)
/ 2 3 4 5 6

Tablespace created.

7. For RAC environment

7.1 Make sure encryption_wallet_location parameter is configured in sqlnet.ora file of all other RAC nodes

1
2
3
4
5
6
ENCRYPTION_WALLET_LOCATION =
         (SOURCE = (METHOD = FILE)
              (METHOD_DATA =
                       (DIRECTORY = /cdbrdbms/etc/$ORACLE_SID)
                )
          )

7.2 Copy the wallet file ewallet.p12 from first RAC node to all other RAC nodes ENCRYPTION_WALLET_LOCATION directory.

Important Note: It is recommended to use shared file location like ACFS or ASM location to hold the TDE wallet file in case of RAC DB.
