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   NOSQL> alter session set container=pdborcl;  ##切换到pdbSession altered.

  确认使用sys连接到了pdborcl

SQL> alter session set container=pdborcl;Session altered.SQL> show userUSER 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 ProductionWith 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--------------------------------------------------------------------------------DEPTEMPBONUSSALGRADESQL> select * from DEPT;    DEPTNO DNAME      LOC---------- -------------- -------------    10 ACCOUNTING     NEW YORK    20 RESEARCH      DALLAS    30 SALES         CHICAGO    40 OPERATIONS      BOSTON
