為了將整個PDB傳輸到不同的平臺，源平臺與目標平臺必須使用相同的位元組序。compatible引數在源CDB資料庫與目標CDB資料庫中必須設定為12.1或更高版本。

下面的例子將Linux平臺上的RAC CDB中的PDB資料庫(jypdb與testpdb)傳輸到windows平臺上的單例項CDB資料庫中。執行跨平臺傳輸的操作如下:
1.檢查源資料庫與目標資料庫的compatible引數是否設定為12.0.0或更高版本
源資料庫

SQL> show parameter compatible

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
compatible                           string      12.2.0
noncdb_compatible                    boolean     FALSE

目標資料庫

SQL> show parameter compatible

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
compatible                           string      12.2.0
noncdb_compatible                    boolean     FALSE

2.檢查源平臺與目標平臺的位元組序
源平臺

SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d  where tp.platform_name=d.platform_name;

PLATFORM_NAME                                                                                         ENDIAN_FORMAT
----------------------------------------------------------------------------------------------------- --------------
Linux x86 64-bit                                                                                      Little

目標平臺

SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d  where tp.platform_name=d.platform_name;

PLATFORM_NAME                                                                       ENDIAN_FORMAT
--------------------------------------------------------------------------------    --------------
Microsoft Windows x86 64-bit                                                        Little

3.將要被傳輸的pdb(jypdb,testpdb)設定為只讀狀態

SQL> alter pluggable database all close immediate;

Pluggable database altered.

SQL> set long 200
SQL> set linesize 200
SQL>  select name,open_mode from v$pdbs;

NAME                                                                                                                             OPEN_MODE
-------------------------------------------------------------------------------------------------------------------------------- ----------
PDB$SEED                                                                                                                         READ ONLY
JYPDB                                                                                                                            MOUNTED
TESTPDB                                                                                                                          MOUNTED

4.備份要傳輸的PDB資料庫，可以使用以下一種方法來跨平臺傳輸PDB
4.1使用RMAN連線到CDB的root容器，並使用backup for transport ... pluggable database或者backup to platform ... pluggable database命令來為PDB建立跨平臺備份。

4.2使用RMAN連線到PDB，並使用backup for transport或backup to platform命令來為PDB建立跨平臺備份。

因為我這裡要傳輸兩個PDB所以選擇第一種方法

RMAN> backup for transport unplug into '/ora_backup/tpdbs/metadata_jypdb.xml' pluggable database jypdb  format '/ora_backup/tpdbs/pdb_%U';

5.將在源平臺上使用rman backup命令生成的備份集與備份的控制檔案傳輸到目標平臺的D:\app\oracle\oradata\pdbs目錄中

6.將PDB(jypdb,testpdb)還原到目標資料庫

RMAN> restore from platform 'Linux x86 64-bit'   foreign pluggable database jypdb  to new from backupset 'D:\app\oracle\oradata\pdbs\pdb_8csqvqc5_1_1';

7.在目標主機上修改metadata_jypdb.xml與metadata_testpdb.xml檔案將資料檔案路徑修改為還原後資料檔案所在路徑

8.將傳輸過來的PDB(jypdb,testpdb)插入CDB

SQL> create pluggable database jypdb using 'D:\app\oracle\oradata\pdbs\metadata_jypdb.xml' nocopy;

插接式資料庫已建立。


SQL> create pluggable database testpdb using 'D:\app\oracle\oradata\pdbs\metadata_testpdb.xml' nocopy ;

插接式資料庫已建立。

SQL> set long 200
SQL> set linesize 200
SQL> select name,open_mode from v$pdbs;

JYPDB                                                                                                                    READ WRITE

9.查詢tts.t1與cs.t2表中的資料來驗證跨平臺傳輸PDB是否操作成功

SQL> select count(*) from tts.t1;

  COUNT(*)
----------
        90

SQL> select count(*) from cs.t2;

  COUNT(*)
----------
        92

到此，跨平臺傳輸PDB就完成了。

Oracle 12C RMAN Cross-Platform Transport of PDBs
