在根容器中创建并激活一个主密钥

ADMINISTER KEY MANAGEMENT SET KEY IDENTIFIED BY AAbb1234 WITH BACKUP;

PDB创建主密钥

ADMINISTER KEY MANAGEMENT SET KEY IDENTIFIED BY myPassword WITH BACKUP;

数据库关闭在开后

使用 TDE 的密钥库

CREATE TABLESPACE encrypted_ts

DATAFILE '/u02/oradata/CDB1/encrypted_ts01.dbf' SIZE 128K

AUTOEXTEND ON NEXT 64K

ENCRYPTION USING 'AES256'

DEFAULT STORAGE(ENCRYPT);

测试用户

CREATE USER lihao IDENTIFIED BY AAbb1234;

GRANT CREATE SESSION TO lihao;

grant create table to lihao;

ALTER USER lihao QUOTA UNLIMITED ON encrypted_ts;

创建表

CREATE TABLE tde_ts_test (

  id    NUMBER(10),

  data  VARCHAR2(50)

) TABLESPACE encrypted_ts;

INSERT INTO tde_ts_test VALUES (1, 'mi mi');

Commit;

PDB重新启动，则必须先在PDB中打开密钥库，然后才能访问数据

ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY AAbb1234;

show user

SELECT * FROM tde_ts_test;

重新启动CDB，则必须在CDB和PDB 中打开密钥库
