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）
1[oracle@xqzt admin]$ pwd 2/data/app/oracle/product/12.1.0/dbhome_1/network/admin 3[oracle@xqzt admin]$ cat tnsnames.ora 4# tnsnames.ora Network Configuration File: /data/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora 5# Generated by Oracle configuration tools. 6 7ORCL = 8 (DESCRIPTION = 9 (ADDRESS = (PROTOCOL = TCP)(HOST = xqzt)(PORT = 1521)) 10 (CONNECT_DATA = 11 (SERVER = DEDICATED) 12 (SERVICE_NAME = orcl) 13 ) 14 ) 15 16 17PDBORCL = 18 (DESCRIPTION = 19 (ADDRESS = (PROTOCOL = TCP)(HOST = xqzt)(PORT = 1521)) 20 (CONNECT_DATA = 21 (SERVER = DEDICATED) 22 (SERVICE_NAME =pdborcl) 23 ) 24 )
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
1SQL> show pdbs 2 3 CON_ID CON_NAME OPEN MODE RESTRICTED 4---------- ------------------------------ ---------- ---------- 5 2 PDB$SEED READ ONLY NO 6 3 PDBORCL READ WRITE NO 7SQL> alter session set container=pdborcl; ##切换到pdb 8 9Session altered.
确认使用sys连接到了pdborcl
1SQL> alter session set container=pdborcl; 2 3Session altered. 4 5SQL> show user 6USER is "SYS" 7SQL> show con_name; 8 9CON_NAME 10------------------------------ 11PDBORCL
执行utlsampl.sql 脚本
1SQL> @$ORACLE_HOME/rdbms/admin/utlsampl.sql 2Disconnected from Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production 3With 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
1SQL> alter session set container=pdborcl; 2 3Session altered. 4 5SQL> select username from dba_users where username = 'SCOTT'; 6 7USERNAME 8-------------------------------------------------------------------------------- 9SCOTT
以scott登录 查询数据
1SQL> conn scott/tiger@pdborcl 2Connected. 3SQL> select table_name from user_tables; 4 5TABLE_NAME 6-------------------------------------------------------------------------------- 7DEPT 8EMP 9BONUS 10SALGRADE 11 12SQL> select * from DEPT; 13 14 DEPTNO DNAME LOC 15---------- -------------- ------------- 16 10 ACCOUNTING NEW YORK 17 20 RESEARCH DALLAS 18 30 SALES CHICAGO 19 40 OPERATIONS BOSTON
