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