本文介绍如何利用Oracle12c的新特性将PDB从Linux环境迁移到Windows环境，涉及PDB元数据导出、数据文件拷贝及新PDB创建等关键步骤。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

对ArcSDE for Oracle数据库来说，数据迁移包括的方式比较多：逻辑迁移、冷备份、热备份、RMAN，当然也包括ArcGIS本身的Copy/Paste方式，那么在Oracle12c这个新的版本也引入了PDB和CDB的概念，感兴趣的用户可以查看Oracle12c的官方帮助。

今天介绍的就是使用Oracle12c新特性的方法来京CDB中的PDB迁移到另外一个CDB中。对PDB的概念，一般大家认为是可插入式的数据库，就像你使用U盘原来在别人的电脑上，现在从别人电脑上拔出，然后插入你自己的电脑上，这种方式也就是相当于数据的迁移。

测试环境：

源环境：

Redhat 5.5 、Oracle12.1.0.1（CDB:orcl 、PDB:pdborcl)、 ArcSDE10.2.1 、192.168.220.203

目标环境：

Windows Server2012、Oracle12.1.0.1（CDB：orcl、PDB：pdborcl1和pdborcl2 ）、ArcSDE10.2.1、192.168.100.213

我的Linux环境下的ArcSDE10.2.1 for Oracle12c的业务数据已经导入，而且可读可写，所在的PDB为pdborcl，希望将这个pdborcl迁移到Window环境下。

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

迁移原理：将Linux环境的PDB生成一个描述该PDB的XML元数据文件，然后将该PDB的相关数据文件和该XML元数据文件拷贝到Windows机器上，在创建新的PDB使用这些XML元数据文件和数据文件即可。

1：查看Linux环境的PDB状态

[oracle@oracle12c orcl]$ sqlplus sys/oracle@orcl as sysdba

SQL*Plus: Release 12.1.0.1.0 Production on Sat Feb 15 06:30:09 2014

SQL> select name from v$datafile;

14 rows selected.

SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;

    CON_ID       DBID NAME                           OPEN_MODE
---------- ---------- ------------------------------ ----------

         3 2266793495 PDBORCL                        MOUNTED

2：导出Linux环境的PDB的元数据文件

SQL> alter pluggable database pdborcl unplug into '/home/oracle/pdborcl.xml';

Pluggable database altered.

SQL> !ls /home/oracle
app  database  Desktop  pdborcl.xml

3：将Linux环境的导出的XML文件和PDBORCL的数据文件物理拷贝到Windows环境下。默认的路径为c:\pdborcl.xml和c:\pdborcl\*.dbf。

4：打开相关的pdborcl.xml

5：使用创建PDB语句

C:\Users\Administrator>sqlplus sys/oracle@localhost/orcl as sysdba

SQL*Plus: Release 12.1.0.1.0 Production on 星期五 2月 28 22:59:53 2014

Copyright (c) 1982, 2013, Oracle.  All rights reserved.


连接到:
Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production
With the Partitioning, Oracle Label Security, OLAP, Advanced Analytics
and Real Application Testing options

SQL> select con_id,dbid,name,open_mode from v$pdbs;

    CON_ID       DBID NAME                           OPEN_MODE
---------- ---------- ------------------------------ ----------
         2 4083344342 PDB$SEED                       READ ONLY
         3 1246209042 PDBORCL1                       MOUNTED
         4 1218627613 PDBORCL2                       MOUNTED


SQL> create pluggable database pdbsde using 'C:\pdborcl.xml' copy file_name_conv
ert=('/home/oracle/app/oracle/oradata/orcl/pdborcl/','C:\app\oracle\oradata\orcl
\pdborcl\');
create pluggable database pdbsde using 'C:\pdborcl.xml' copy file_name_convert=(
'/home/oracle/app/oracle/oradata/orcl/pdborcl/','C:\app\oracle\oradata\orcl\pdbo
rcl\')
*
第 1 行出现错误:
ORA-19505:
无法识别文件"/home/oracle/app/oracle/oradata/orcl/pdborcl/system01.dbf"
ORA-27041: 无法打开文件
OSD-04002: 无法打开文件
O/S-Error: (OS 3) 系统找不到指定的路径。

6：将pdborcl.xml文件里面的数据文件路径修改为存储在Windows环境的实际路径，如c:\pdborcl\sde01等，而且在数据文件参数设置也应该设置为Windows路径下，而且这些数据文件的目的存储为C:\app\oracle\oradata\orcl\pdborcl\

该步骤涉及到数据文件的拷贝，根据数据量大小时间有所不一样

SQL> create pluggable database pdbsde using 'C:\pdborcl.xml' copy file_name_conv
ert=('c:\pdborcl\','C:\app\oracle\oradata\orcl\pdborcl\');

插接式数据库已创建。

7：打开新的PDB（pdbsde）并查看状态

[oracle@oracle12c orcl]$ sqlplus sys/oracle@orcl as sysdba

SQL*Plus: Release 12.1.0.1.0 Production on Sat Feb 15 06:30:09 2014

SQL> select con_id,dbid,name,open_mode from v$pdbs;

    CON_ID       DBID NAME                           OPEN_MODE
---------- ---------- ------------------------------ ----------
         2 4083344342 PDB$SEED                       READ ONLY
         3 1246209042 PDBORCL1                       MOUNTED
         4 1218627613 PDBORCL2                       MOUNTED
         5 2266793495 PDBSDE                         MOUNTED

SQL> alter pluggable database pdbsde open;

插接式数据库pdbsde已打开

SQL> select con_id,dbid,name,open_mode from v$pdbs;

    CON_ID       DBID NAME                           OPEN_MODE
---------- ---------- ------------------------------ ----------
         2 4083344342 PDB$SEED                       READ ONLY
         3 1246209042 PDBORCL1                       MOUNTED
         4 1218627613 PDBORCL2                       MOUNTED
         5 2266793495 PDBSDE                         READ WRITE

8：使用sqlplus 连接sde用户

SQL> conn sde/sde@192.168.100.213/pdbsde
ERROR:
ORA-01035: ORACLE ？？？êDí？？óD RESTRICTED SESSION
è¨？Tμ？ó？？§ê1ó？


警告: 您不再连接到 ORACLE。

提示ORA-01035错误，需要赋予RESTRICTED SESSION权限

SQL> conn system/oracle@192.168.100.213/pdbsde
已连接。
SQL> grant restricted session to sde;

授权成功。

SQL> conn sde/sde@192.168.100.213/pdbsde
已连接。

9：使用ArcCatalog10.2.1进行读写测试

总结：个人感觉，该方面有点类似于Oracle的冷备份，不过在实施过程中操作比较简单，尤其是ArcGIS版本化数据的迁移，既保证了简单操作性又保持了高效，值得用户进行参考！
