Oracle Encrypted Tablespaces


实验:创建加密表空间,并插入测试数据

一:查看现有wallet
SQL>  select * from v$encryption_wallet;
WRL_TYPE             WRL_PARAMETER                       STATUS
-------------------- ----------------------------------- ------------------
file                 /u01/app/oracle/admin/orcl/wallet  CLOSED

二:创建目录
SQL> ho mkdir /u01/app/oracle/admin/orcl/wallet

三:创建加密KEY
SQL> alter system set encryption key identified by oracle;

四:查看现有wallet状态
SQL> select * from v$encryption_wallet;
WRL_TYPE             WRL_PARAMETER                       STATUS
-------------------- ----------------------------------- ------------------
file                 /u01/app/oracle/admin/orcl/wallet   OPEN

五:创建加密表空间
SQL> create tablespace test_encrypt datafile '/u01/app/oracle/oradata/orcl/test_encrypt01.dbf' size 10M encryption default storage(encrypt);
Tablespace created.

SQL> SELECT TABLESPACE_NAME, ENCRYPTED FROM DBA_TABLESPACES;

TABLESPACE_NAME                ENC
------------------------------ ---
SYSTEM                         NO
SYSAUX                         NO
UNDOTBS1                       NO
TEMP                           NO
USERS                          NO
TEST_ENCRYPT                   YES

6 rows selected.

SQL> SELECT NAME, ENCRYPTIONALG ENCRYPTEDTS
FROM V$ENCRYPTED_TABLESPACES, V$TABLESPACE
WHERE V$ENCRYPTED_TABLESPACES.TS# = V$TABLESPACE.TS#; 

NAME                           ENCRYPT
------------------------------ -------
TEST_ENCRYPT                   AES128

六:创建测试数据
SQL> create table t1(id number,name varchar2(20)) tablespace test_encrypt;
SQL> create table t2(id number,name varchar2(20)) tablespace users;

SQL> insert into t1 values(1,'a');
SQL> commit;
SQL> insert into t2 values(2,'b');
SQL> commit;

七:重启数据库后,钱包自动关闭,并且无法查询加密表空间里的数据
SQL> shutdown immediate
SQL> startup

SQL> select * from t1;
select * from t1
              *
ERROR at line 1:
ORA-28365: wallet is not open

---数据库重启后,钱包会自动关闭
SQL> select * from v$encryption_wallet;
WRL_TYPE             WRL_PARAMETER                       STATUS
-------------------- ----------------------------------- ------------------
file                 /u01/app/oracle/admin/orcl/wallet   CLOSED

八:打开钱包
SQL> alter system set wallet open identified by oracle;
System altered.
---SQL> alter system set wallet close identified by oracle;(关闭钱包)

SQL> select * from t1;
        ID NAME
---------- --------------------
         1 a

九:将t2表移动到加密表空间中
SQL> alter table t2 move tablespace test_encrypt;
System altered.
