RMAN跨小版本跨平臺與字節序傳輸表空間
將Linux平臺上的源數據庫中的tspitr與test表空間傳輸到AIX平臺上。並在源主機上使用目錄/u02/transport來存儲被轉換的數據文件。操做步驟以下:
1.將要被傳輸的表空間tspitr與test設置爲只讀web
SQL> alter tablespace tspitr read only; Tablespace altered. SQL> alter tablespace test read only; Tablespace altered.
2.檢查源平臺與目標平臺信息支不支持傳輸操做
數據庫所支持的平臺信息:sql
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

3.確認要被傳輸的表空間是不是自包含表空間(TSPITR,TEST):app
SQL> exec sys.dbms_tts.transport_set_check('TSPITR',true);
PL/SQL procedure successfully completed.
SQL> exec sys.dbms_tts.transport_set_check('TEST',true);
PL/SQL procedure successfully completed.
SQL> select * from sys.transport_set_violations;
no rows selected
若是沒有行選擇，表示該表空間只包含表數據，能夠傳輸。ide
4.記錄表空間傳輸前表tspitr與test中的記錄：工具
SQL> select count(*) from tspitr.tspitr; COUNT(*) ---------- 50315 SQL> select count(*) from test.test; COUNT(*) ---------- 50316
5.使用RMAN將源數據庫中的表空間tspitr,test轉換爲目標平臺字節序格式，使用format參數來控制被轉換後數據文件的文件名和存儲目錄.測試

出錯緣由是由於源數據庫的compatible=10.2.0.5.0,目標數據庫的compatible=10.2.0.3.0這裏在導出使用version=10.2.0.3.0導出元數據後再執行導出也是一樣會報這個錯誤，由於這裏不是邏輯導出，而是傳輸表空間，因此version參數不起做用。因此想修改源數據庫的compatible參數爲10.2.0.3.0,但在10g之後,compatible參數只能增大不能減小。

在將源數據庫的compatible參數修改成10.2.0.3.0後沒法啓動數據庫。
這裏是從10.2.0.5(源數據庫的compatible參數爲10.2.0.5.0)向10.2.0.4(這裏目標數據庫中的compatible參數卻爲10.2.0.3.0，不是10.2.0.4.0）跨平臺傳輸表空間不會成功，也就是從高版本向低版本傳輸表空間不能成功。但從低版本向高版本傳輸表空間是能夠成功，例以下面的示例：
咱們要將Linux平臺上的源數據庫中的tspitr與test表空間傳輸到AIX平臺上。並在源主機上使用目錄/u02/transport來存儲被轉換的數據文件。操做步驟以下:
1.將要被傳輸的表空間tspitr與test設置爲只讀
SQL> alter tablespace tspitr read only; Tablespace altered. SQL> alter tablespace test read only; Tablespace altered.
2.檢查源平臺與目標平臺信息支不支持傳輸操做

3.確認要被傳輸的表空間是不是自包含表空間(TSPITR,TEST):
SQL> exec sys.dbms_tts.transport_set_check('TSPITR',true);
PL/SQL procedure successfully completed.
SQL> exec sys.dbms_tts.transport_set_check('TEST',true);

no rows selected
若是沒有行選擇，表示該表空間只包含表數據，能夠傳輸。
4.記錄表空間傳輸前表tspitr與test中的記錄：
SQL> select count(*) from tspitr.tspitr; COUNT(*) ---------- 50315 SQL> select count(*) from test.test; COUNT(*) ---------- 50316
5.使用RMAN將源數據庫中的表空間tspitr,test轉換爲目標平臺字節序格式，使用format參數來控制被轉換後數據文件的文件名和存儲目錄.

能夠看到，將源數據庫10.2.0.5的compatible設置爲10.2.0.3.0與目標數據庫10.2.0.4的compatible同樣，執行傳輸表空間是能夠執行成功的。
以前使用pfile參數文件參源數據庫的compatible參數從10.2.0.1.0修改成10.2.0.3.0了，如今將其修改成10.2.0.1.0，並從新使用pfile文件啓動源數據庫會報錯。
[oracle@weblogic28 dbs]$ vi initjytest.ora 省.... *.compatible='10.2.0.1.0' SQL> startup pfile='/u01/app/oracle/product/10.2.0/db/dbs/initjytest.ora'; ORACLE instance started.

這也就證實從oracle 10g開始,compatible參數只能增大，不能縮小。
總結:
1.跨小版本執行跨平臺與字節序的表空間傳輸時，源數據庫的compatible參數必須小於或等於目標數據庫的compatible參數
2.當源數據庫的compatible參數大於目標數據庫的compatible參數時，要執行跨平臺與字節序的表空間傳輸只有將目標數據庫升級爲與源數據庫相同的版本號且compatible參數要大於或等於源數據庫的compatible參數。
3.從oracle 10g開始，compatible參數只能增大，不能縮小。
將Linux平臺上的源數據庫中的tspitr與test表空間傳輸到AIX平臺上。並在源主機上使用目錄/u02/transport來存儲被轉換的數據文件。操做步驟以下:
1.將要被傳輸的表空間tspitr與test設置爲只讀
SQL> alter tablespace tspitr read only; Tablespace altered. SQL> alter tablespace test read only; Tablespace altered.
2.檢查源平臺與目標平臺信息支不支持傳輸操做
數據庫所支持的平臺信息:
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$database d where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux 64-bit for AMD Little
目標平臺
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT -------------------------------------------------------------------------------- -------------- AIX-Based Systems (64-bit) Big
3.確認要被傳輸的表空間是不是自包含表空間(TSPITR,TEST):
SQL> exec sys.dbms_tts.transport_set_check('TSPITR',true);
PL/SQL procedure successfully completed.
SQL> exec sys.dbms_tts.transport_set_check('TEST',true);
PL/SQL procedure successfully completed.
SQL> select * from sys.transport_set_violations;
no rows selected
若是沒有行選擇，表示該表空間只包含表數據，能夠傳輸。
4.記錄表空間傳輸前表tspitr與test中的記錄：
SQL> select count(*) from tspitr.tspitr; COUNT(*) ---------- 50315 SQL> select count(*) from test.test; COUNT(*) ---------- 50316
5.使用RMAN將源數據庫中的表空間tspitr,test轉換爲目標平臺字節序格式，使用format參數來控制被轉換後數據文件的文件名和存儲目錄.

出錯緣由是由於源數據庫的compatible=10.2.0.5.0,目標數據庫的compatible=10.2.0.3.0這裏在導出使用version=10.2.0.3.0導出元數據後再執行導出也是一樣會報這個錯誤，由於這裏不是邏輯導出，而是傳輸表空間，因此version參數不起做用。因此想修改源數據庫的compatible參數爲10.2.0.3.0,但在10g之後,compatible參數只能增大不能減小。

在將源數據庫的compatible參數修改成10.2.0.3.0後沒法啓動數據庫。
這裏是從10.2.0.5(源數據庫的compatible參數爲10.2.0.5.0)向10.2.0.4(這裏目標數據庫中的compatible參數卻爲10.2.0.3.0，不是10.2.0.4.0）跨平臺傳輸表空間不會成功，也就是從高版本向低版本傳輸表空間不能成功。但從低版本向高版本傳輸表空間是能夠成功，例以下面的示例：
咱們要將Linux平臺上的源數據庫中的tspitr與test表空間傳輸到AIX平臺上。並在源主機上使用目錄/u02/transport來存儲被轉換的數據文件。操做步驟以下:
1.將要被傳輸的表空間tspitr與test設置爲只讀
SQL> alter tablespace tspitr read only; Tablespace altered. SQL> alter tablespace test read only; Tablespace altered.
2.檢查源平臺與目標平臺信息支不支持傳輸操做
數據庫所支持的平臺信息:
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$database d where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux 64-bit for AMD Little
目標平臺
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT -------------------------------------------------------------------------------- -------------- AIX-Based Systems (64-bit) Big
3.確認要被傳輸的表空間是不是自包含表空間(TSPITR,TEST):
SQL> exec sys.dbms_tts.transport_set_check('TSPITR',true);
PL/SQL procedure successfully completed.
SQL> exec sys.dbms_tts.transport_set_check('TEST',true);
PL/SQL procedure successfully completed.
SQL> select * from sys.transport_set_violations;
no rows selected
若是沒有行選擇，表示該表空間只包含表數據，能夠傳輸。
4.記錄表空間傳輸前表tspitr與test中的記錄：
SQL> select count(*) from tspitr.tspitr; COUNT(*) ---------- 50315 SQL> select count(*) from test.test; COUNT(*) ---------- 50316
5.使用RMAN將源數據庫中的表空間tspitr,test轉換爲目標平臺字節序格式，使用format參數來控制被轉換後數據文件的文件名和存儲目錄.

能夠看到執行成功。雖然源數據庫是10.2.0.5，但其compatible爲10.2.0.1.0,而目標數據庫是10.2.0.4，其compatible參數爲10.2.0.3.0，傳輸表空間是能成功執行的。
下面將源數據庫的compatible修改成10.2.0.3.0（與目標數據庫的compatible同樣)

能夠看到，將源數據庫10.2.0.5的compatible設置爲10.2.0.3.0與目標數據庫10.2.0.4的compatible同樣，執行傳輸表空間是能夠執行成功的。
以前使用pfile參數文件參源數據庫的compatible參數從10.2.0.1.0修改成10.2.0.3.0了，如今將其修改成10.2.0.1.0，並從新使用pfile文件啓動源數據庫會報錯。
[oracle@weblogic28 dbs]$ vi initjytest.ora 省.... *.compatible='10.2.0.1.0' SQL> startup pfile='/u01/app/oracle/product/10.2.0/db/dbs/initjytest.ora'; ORACLE instance started. Total System Global Area 1073741824 bytes Fixed Size 2101736 bytes Variable Size 335547928 bytes Database Buffers 729808896 bytes Redo Buffers 6283264 bytes ORA-00201: control file version 10.2.0.3.0 incompatible with ORACLE version 10.2.0.1.0 ORA-00202: control file: '/u01/app/oracle/oradata/jytest/control01.ctl'
這也就證實從oracle 10g開始,compatible參數只能增大，不能縮小。
總結: 1.跨小版本執行跨平臺與字節序的表空間傳輸時，源數據庫的compatible參數必須小於或等於目標數據庫的compatible參數 2.當源數據庫的compatible參數大於目標數據庫的compatible參數時，要執行跨平臺與字節序的表空間傳輸只有將目標數據庫升級爲與源數據庫相同的版本號且compatible參數要大於或等於源數據庫的compatible參數。 3.從oracle 10g開始，compatible參數只能增大，不能縮小。
