Oracle 12c 如何在 PDB 中添加 SCOTT 模式（手工方式）

Oracle 12c 建库后，没有 scott 模式，本篇使用手工脚本方式，在12c版本中创建 scott 模式及相关表。

目录

1. PDB中创建用户

2. PDB中用户授权

3. PDB中创建表空间

4. PDB中设置用户默认表空间

5. 运行脚本文件

6. 设置TNSNAMES.ora

7. 连接测试验证数据

1. PDB中创建用户

SQL> show pdbs

   CON_ID CON_NAME     OPEN MODE  RESTRICTED
--------- ------------ ---------- ----------
     2 　　PDB$SEED     READ ONLY  NO
     3 　　PDB1         READ WRITE NO
     4 　　PDB2         READ WRITE NO
     5 　　PDB3         READ WRITE NO
SQL> alter session set container=pdb2;

Session altered.

SQL> show pdbs

    CON_ID CON_NAME    OPEN MODE  RESTRICTED
---------- ----------- ---------- ----------
     4 　　PDB2 　　　　 READ WRITE NO
SQL> create user scott identified by tiger;

User created.

2. PDB中创建表空间

创建USERS表空间（测试环境名字可以自定义）。

注意语句没有指定路径，是因为这里在PDB中设置了参数 db_create_file_dest，启用了OMF（Oracle Managed Files），文件不用指定路径，自动管理。

SQL> create tablespace users datafile size 100m;

Tablespace created.

SQL> select name from v$tablespace;

NAME
-----------------------------------
SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS

3. PDB中用户授权

SQL> grant connect,resource,unlimited tablespace to scott;

Grant succeeded.

4. PDB中设置用户默认表空间

SQL> alter user scott default tablespace users;

User altered.

SQL> alter user scott temporary tablespace temp;

User altered.

5. 运行脚本文件

SQL> @scott.sql

6. 设置TNSNAMES.ora

[oracle@henry ~]$ cd $ORACLE_HOME/network/admin
[oracle@henry admin]$ vim tnsnames.ora 

添加

PDB2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = henry)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = PDB2)
    )
  )

7. 连接测试验证数据

[oracle@henry admin]$ sqlplus scott/tiger@pdb2
