对于熟悉Oracle或者接触过Oracle的人，scott这个用户大家一定相当的熟悉。12c推出了可插拔数据库，在一个容器cdb中以多租户的形式同时存在多个数据库pdb。pdb中默认不包含scott用户。

为了做数据泵的实验，需要一个测试用户，因此需要在pdb中添加scott用户。

oracle 12c自带了scott的脚本，$ORACLE_HOME/rdbms/admin/utlsampl.sql 内容如下：

下面就利用这段脚本，在pdb中恢复scott

1、为pdb添加tnsnames (步骤2后面用的到)

[oracle@xqzt admin]$ pwd

/data/app/oracle/product/12.1.0/dbhome_1/network/admin

[oracle@xqzt admin]$ cat tnsnames.ora

# tnsnames.ora Network Configuration File: /data/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

ORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = xqzt)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

PDBORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = xqzt)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME =pdborcl)

)

)

2、修改utlsampl.sql

将  connect scott/tiger 改为  connect  scott/tiger@PDBORCL

3、使用sys登录plsql，切换到要导入的容器pdb ,执行utlsampl.sql

切换到容器pdborcl

SQL> show pdbs

CON_ID CON_NAME OPEN MODE RESTRICTED

---------- ------------------------------ ---------- ----------

2 PDB$SEED READ ONLY NO

3 PDBORCL READ WRITE NO

SQL> alter session set container=pdborcl; ##切换到pdb

Session altered.

确认使用sys连接到了pdborcl

SQL> alter session set container=pdborcl;

Session altered.

SQL> show user

USER is "SYS"

SQL> show con_name;

CON_NAME

------------------------------

PDBORCL

执行utlsampl.sql 脚本

SQL> @$ORACLE_HOME/rdbms/admin/utlsampl.sql

Disconnected from Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production

With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options

4、验证导入结果

查询是否存在scott用户

SQL> alter session set container=pdborcl;

Session altered.

SQL> select username from dba_users where username = 'SCOTT';

USERNAME

--------------------------------------------------------------------------------

SCOTT

以scott登录 查询数据

SQL> conn scott/tiger@pdborcl

Connected.

SQL> select table_name from user_tables;

TABLE_NAME

--------------------------------------------------------------------------------

DEPT

EMP

BONUS

SALGRADE

SQL> select * from DEPT;

DEPTNO DNAME LOC

---------- -------------- -------------
