oracle跨版本與平臺執行傳輸表空間
將aix(10.2.0.4)平臺上的源資料庫中的tspitr表空間傳到linux(11.2.0.4)平臺，並在源主機上使用目錄/yb_oradata/transport來儲存被轉換的資料檔案。操作步驟如下:
1.將要被傳輸的表空間tspitr設定為只讀
SQL> alter tablespace tspitr read only; Tablespace altered. SQL> select tablespace_name,status from dba_tablespaces where tablespace_name='TSPITR'; TABLESPACE_NAME STATUS ------------------------------ --------- TSPITR READ ONLY
2.檢查源平臺與目標平臺資訊看是滯支援傳輸操作，資料庫所支援的平臺資訊如下:
SQL> select platform_name,endian_format from v$transportable_platform; PLATFORM_NAME ENDIAN_FORMAT -------------------------------------------------------------------------------- -------------- Solaris[tm] OE (32-bit) Big Solaris[tm] OE (64-bit) Big Microsoft Windows IA (32-bit) Little Linux IA (32-bit) Little AIX-Based Systems (64-bit) Big HP-UX (64-bit) Big HP Tru64 UNIX Little HP-UX IA (64-bit) Big Linux IA (64-bit) Little HP Open VMS Little Microsoft Windows IA (64-bit) Little IBM zSeries Based Linux Big Linux x86 64-bit Little Apple Mac OS Big Microsoft Windows x86 64-bit Little Solaris Operating System (x86) Little IBM Power Based Linux Big Solaris Operating System (x86-64) Little HP IA Open VMS Little
源平臺:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d where tp.platform_name=d.platform_name; PLATFORM_NAME ENDIAN_FORMAT -------------------------------------------------------------------------------- -------------- AIX-Based Systems (64-bit) Big
目標平臺:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d where tp.platform_name=d.platform_name; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux x86 64-bit Little
3.確認要被傳輸的表空間是否是自包含表空間(TSPITR):
SQL> exec sys.dbms_tts.transport_set_check('TSPITR',true);
PL/SQL procedure successfully completed.
SQL> select * from sys.transport_set_violations;
no rows selected
沒有記錄，表示該表空間只包含表資料，可以傳輸。
4.記錄表空間傳輸前表tspitr中的記錄：
SQL> select count(*) from tspitr.tspitr;
COUNT(*)
----------
50315
5.使用RMAN將源資料庫中的表空間tspitrt轉換為目標平臺位元組序格式，使用format引數來控制被轉換後資料檔案的檔名和儲存目錄.

查詢tspitr表中的記錄，與源資料庫中的記錄數一致。
SQL> select count(*) from tspitr.tspitr;
COUNT(*)
----------
50315
現在使用者tspitr的預設表空間不是tspitr
SQL> select username,default_tablespace,temporary_tablespace from dba_users where username='TSPITR'; USERNAME DEFAULT_TABLESPACE TEMPORARY_TABLESPACE ------------------------------ ------------------------------ ------------------------------ TSPITR USERS TEMP
將使用者tspitr的預設表空間修改為tspitr
SQL> alter user tspitr default tablespace tspitr;
User altered
SQL> select username,default_tablespace,temporary_tablespace from dba_users where username='TSPITR';
USERNAME DEFAULT_TABLESPACE TEMPORARY_TABLESPACE
------------------------------ ------------------------------ ------------------------------
TSPITR TSPITR TEMP
SQL> select count(*) from tspitr.tspitr;
COUNT(*)
----------
50315
現在表tspitr的儲存表空間也變為tspitr
SQL> select owner,table_name,tablespace_name from dba_tables where table_name='TSPITR'; OWNER TABLE_NAME TABLESPACE_NAME ------------------------------ ------------------------------ ------------------------------ TSPITR TSPITR TSPITR
9.將源資料庫中的tspitr表空間修改為讀寫模式
SQL> alter tablespace tspitr read write; Tablespace altered. SQL> select tablespace_name,status from dba_tablespaces where tablespace_name='TSPITR'; TABLESPACE_NAME STATUS ------------------------------ --------- TSPITR ONLINE
