一.3  相關知識點掃盲

可傳輸表空間的特性主要用於進行庫對庫的表空間複製，要進行傳輸的表空間必須置於read-only模式。如果生產庫不允許表空間置為只讀模式，沒關係，方法還是有的，通過RMAN備份也可以建立可傳輸表空間集。要使用可傳輸表空間的特性，oracle至少是8i企業版或更高版本。如果是相同作業系統平臺相互匯入，則8i及以上版本均可支援，但如果是不同作業系統平臺，資料庫版本至少10g。被傳輸的表空間即可以是字典管理，也可以是本地管理。並且自oracle9i開始，被傳輸表空間的block size可以與目標資料庫的block size不同。

 

可傳輸表空間(還有個集)最大的優勢是其速度比export/import或unload/load要快的多。因為可傳輸表空間主要是複製資料檔案到目標路徑，然後再使用export/import或Data Pump export/import等應用僅匯出/匯入表空間物件的後設資料到新資料庫。

關於可傳輸表空間，還有個集(Transportable Tablespace Sets)的建立，其中都提到了很重要一點，就是被傳輸的表空間在傳輸過程中必須置為 read-only。而在實際操作過程中，對於某些生產資料庫，將表空間置為 read-only 是件非常複雜的事情甚至完全不允許，有了 RMAN 的 Transportable Tablespace，這一切都得以避免。RMAN 通過備份建立可傳輸表空間集，它並不需要存取活動的資料檔案，相應也就不需要將表空間置為 read-only。因此，資料庫可用性得到提升，尤其對於超大的表空間，因為被傳輸的表空間在此期間仍可進行讀寫操作，而且把表空間置為 read-only 模式可能會花費較長時間，

使用 RMAN 建立可傳輸表空間集，允許你在傳輸過程中指定目標恢復時間點或 SCN，這樣傳輸的資料可以更靈活，不必完全複製現有表空間，只要備份中存在，你就可以選擇性的恢復資料。例如，你的備份策略為保留一週，你希望建立的可傳輸表空間中資料是截止本月底最後一天的資料，那麼你在下個月第一週內任何時候都可以進行傳輸操作而不需要考慮這期間生產庫是否會有寫入操作。

 

一.3.1  注意事項

 

 

 

?  注意：

 

① source和target database的資料庫版本最好一致，否則會因為db time zone 不一致導致報如下錯誤，但是如果source大於等於target的話是可以的，向下相容的

ORA-39002: invalid operation

ORA-39322: Cannot use transportabletablespace with timestamp with timezone columns and different timezone version.

 

② source和target端的字符集必須一致，例如如下情況報錯：

source為 ZHS16GBK，target為AL32UTF8

ORA-39123: Data Pump transportable tablespace job aborted

ORA-29345: cannot plug a tablespace into a database using an incompatible character set

 

Tartget db char set AL32UTF8 is not a superset of ZHS16GBK.

Failed to plug in a tablespace due to incompatible

  database character set"AL32UTF8" and

  transportable set database character set "ZHS16GBK"

 

  ③ source和target database的compatible 引數最好一致，但source如果小於等於target端的話是可以的，例如source為11.2.0.4.0，target為11.2.0.0.0就不行，impdp的時候報錯：

ORA-39123: Data Pump transportable tablespace job aborted

ORA-00721: changes by release 11.2.0.4.0 cannot be used by release 11.2.0.0.0

一.4.2  實驗目標

 

要實現將自定義的應用程式表空間app1tbs,app2tbs,idxtbs從源平臺傳遞到目標平臺，而在實際的工作過程中，需要將AIX上的資料庫遷移到Linux，或者將Linux上的資料庫遷移到AIX上，除了exp/imp和expdp/impdp外，最常用的就是傳輸表空間了，若是整個庫遷移的話，我們需要做的就是把業務使用者和業務表空間的資料遷移過來就行，Undo、temp、system等等的就不用遷移了，整個處理過程和本文件的處理過程大同小異，需要關注的是業務物件的個數、大小、狀態等。

一.6  判斷平臺支援並確定位元組序

如果傳輸表空間集到不同的平臺，則要確定對於源和目標平臺這種跨平臺表空間被支援，也要確定每個平臺的位元組序，如果平臺具有相同的位元組序，則不需要進行轉化，否則必須做一個表空間集轉化，在源端或目標端。

一.6.1  在源平臺查詢

PLATFORM_NAME                            ENDIAN_FORMAT

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

AIX-Based Systems (64-bit)               Big

 

 

 

結論： 當前的AIX平臺支援跨平臺的表空間傳輸

源平臺和目標平臺的Endian_format 不同，source端為Little，target端為Big，所以需要進行表空間集轉換，前邊說過在源端或目標端都可以進行轉換，這裡我們選擇在目標端來進行轉換。

 

一.7  選擇自包含的表空間集

一.7.1  進行檢查

Indicates whether a full or partial dependency check is required. If TRUE, treats all IN and OUT pointers(dependencies) and captures them as violations if they are not self-contained in the transportable set.

先試試要傳輸app1tbs和idxtbs這2個表空間：

 

SQL> execute dbms_tts.transport_set_check('app1tbs,idxtbs',true);

 

PL/SQL procedure successfully completed.

 

 

一.7.2  檢視檢查結果

SQL> col violations for a70

 

23:50:53 SQL> select * from transport_set_violations;

 

VIOLATIONS

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

ORA-39907: 索引 USER_APP2.IDX_DEPT_DNAME (在表空間 IDXTBS 中) 指向表 USER_APP2.APP2_TAB (在表空間 APP2TBS 中)。

 

已用時間:  00: 00: 00.18

23:51:14 SQL>

 

結論： 在idxtbs表空間中IDX_DEPT_DNAME索引指向了表空間集外的USER_APP2.APP2_TAB表，所以這裡選擇app1tabs,app2tabs,idxtbs作為新的表空間集再次進行檢查

 

23:51:14 SQL> execute dbms_tts.transport_set_check('app1tbs,app2tbs,idxtbs',true);

 

PL/SQL 過程已成功完成。

 

已用時間:  00: 00: 07.24

未選定行

 

已用時間:  00: 00: 00.00

23:52:54 SQL>

結論： 此時這個表空間集已經不再違背自包含的條件，可以確定為一個可傳輸表空間集。在實際生產環境中也是如此檢查的，若是全庫遷移，得把需要遷移的表空間修改為自包含的。

 

一.8  產生可傳輸表空間集
