1 場景描述

源平臺爲：rhel6.5 + oracle 11.2.0.3.0 + asm 64位sql

目標平臺：windows xp 32系統 + oracle 11.2.0.1.0windows

要實現將自定義的應用程序表空間app1tbs,app2tbs,idxtbs從源平臺傳遞到目標平臺oracle

2 環境準備

2.1 在源庫上建立3個用戶應用的表空間

2.2 在相應的表空間建立表和索引

SQL> create table scott.app1_tab tablespace app1tbs as select * from scott.emp;

Table created.

SQL> create table scott.app2_tab tablespace app2tbs as select * from scott.dept;

Table created.

SQL> create index scott.idx_emp_ename on scott.app1_tab(ename) tablespace idxtbs;

Index created.

SQL> create index scott.idx_dept_dname on scott.app2_tab(dname) tablespace idxtbs;

Index created.

SQL>

3 判斷平臺支持並肯定字節序

若是傳輸表空間集到不一樣的平臺，則要肯定對於源和目標平臺這種跨平臺表空間被支持，也要肯定每一個平臺的字節序，若是平臺具備相同的字節序，則不須要進行轉化，不然必須作一個表空間集轉化，在源端或目標端。

3.1 在源平臺查詢

SQL> col platform_name for a40

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

2 where tp.platform_name=d.platform_name;

PLATFORM_NAME ENDIAN_FORMAT

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

Linux x86 64-bit Little

SQL>

結論：當前的系統平臺支持跨平臺表空間傳輸（由於上面的查詢有記錄返回）

3.2 在目標平臺查詢

SQL> col platform_name for a40

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

2 where tp.platform_name=d.platform_name;

PLATFORM_NAME ENDIAN_FORMAT

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

Microsoft Windows IA (32-bit) Little

結論：當前的windows 平臺支持跨平臺的表空間傳輸

源平臺和目標平臺的Endian_format 相同（均爲Little），不須要進行表空間集轉換

4 選擇自包含的表空間集（目前要傳輸app1tbs和idxtbs這2個表空間）

4.1 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.

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

PL/SQL procedure successfully completed.

4.2 查看檢查結果

SQL> col violations for a70

SQL> select * from transport_set_violations;

VIOLATIONS

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

ORA-39907: Index scott.IDX_DEPT_DNAME in tablespace IDXTBS points to table scott.APP2_TAB in tablespace APP2TBS.

SQL>

結論：在idxtbs表空間中IDX_DEPT_DNAME索引指向了表空間集外的SYS.APP2_TAB表，因此這裏選擇app1tabs,app2tabs,idxtbs做爲新的表空間集再次進行檢查

SQL> execute dbms_tts.transport_set_check('app1tbs,app2tbs,idxtbs',true);

PL/SQL procedure successfully completed.

SQL> select * from transport_set_violations;

no rows selected

SQL>

結論：此時這個表空間集已經不在違背自包含的條件，能夠肯定爲一個可傳輸表空間集

5 產生可傳輸表空間集

5.1 使自包含的表空間集中的全部表空間變爲只讀狀態

SQL> alter tablespace app1tbs read only;

Tablespace altered.

SQL> alter tablespace app2tbs read only;

Tablespace altered.

SQL> alter tablespace idxtbs read only;

Tablespace altered.

5.2 使用數據泵導出工具，導出要傳輸的各個表空間的元數據

5.2.1 肯定導出目錄

SQL> set line 9999

SQL> col directory_name for a25

SQL> col directory_path for a100

SQL> select directory_name,directory_path from dba_directories;

DIRECTORY_NAME DIRECTORY_PATH

本實例是源庫爲asm，目標庫爲os文件，另外，若是源庫爲os文件，而目標庫爲asm文件的話，以上步驟不變，在最後修改表空間對應的數據文件名稱的時候使用rman 鏡像拷貝來重命名文件便可。

② rman 執行：

backup as copy datafile 6 format ‘+DATA/ORCLASM/XXX.DBF’;

SWITCH TABLESPACE APP1TBS TO COPY;

ALTER DATABSE OPEN;
