0、準備工作

--創建被傳輸的表空間

SQL> create tablespace tbs_single

datafile 'c:\oracle\oradata\ora9i\tbs_single01.dbf' size 100M

extent management local;

--創建用戶，并將表空間作為默認表空間

SQL> create user tranp identified by oracle default tablespace tbs_single;

SQL> grant connect,resource to tranp;

--在該表空間創建表，用于測試

SQL> create table tranp.t01 as select * from sys.dba_objects;

1、檢查源、目標平臺Endianness

在源 數據庫 平臺上：

SQL> SELECT d.PLATFORM_NAME, ENDIAN_FORMAT

2 FROM V$TRANSPORTABLE_PLATFORM. tp, V$DATABASE d

3 WHERE tp.PLATFORM_NAME = d.PLATFORM_NAME;

PLATFORM_NAME ENDIAN_FORMAT

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

Microsoft Windows IA (32-bit) Little

在目標數據庫平臺上：

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 IA (32-bit) Little

由于源和目標平臺的Endianness一致，可以省去convert這一步。

2、檢查要表空間是否自包含

SQL> EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK('TBS_SINGLE',true);

PL/SQL過程已成功完成。

SQL> SELECT * FROM TRANSPORT_SET_VIOLATIONS;

未選定行

說明表空間是自包含的。

3、產生傳輸表空間集

創建目錄對象

SQL> create DIRECTORY tranp_dir as 'c:\software';

目錄已創建。

SQL> grant read,write on DIRECTORY tranp_dir to public;

授權成功。

將表空間置為只讀。

SQL> alter tablespace tbs_single read only;

表空間已更改。

使用數據泵導出傳輸表空間的元數據

注：如果Endianness不一致，還需要使用RMAN進行轉換表空間的數據文件。

4、傳送表空間集

將表空間的數據文件和導出的DMP文件，傳送到目標數據庫平臺上。

5、導入表空間

在目標數據庫中，創建相應的目錄對象和用戶。

SQL> create directory tranp_dir as '/home/oracle';

Directory created.

SQL> grant read,write on directory tranp_dir to public;

Grant succeeded.

SQL> create user tranp identified by oracle;

User created.

SQL> grant connect,resource to tranp;

Grant succeeded.

使用數據庫泵，導入到目標數據庫中。

[oracle@ocmu ~]$ impdp system/oracle dumpfile=TBSINGLE.DMP directory=tranp_dir transport_datafiles=/u01/app/oracle/oradata/PROD/TBS_SINGLE01.DBF remap_schema=tranp:tranp

Job "SYSTEM"."SYS_IMPORT_TRANSPORTABLE_01" successfully completed at 23:40:29

將被導入的表空間置為read write。

SQL> alter tablespace TBS_SINGLE read write;

Tablespace altered.

6、測試

目標庫中，進行測試。

SQL> select name from v$tablespace;

NAME

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

SYSTEM

UNDOTBS1

SYSAUX

USERS

TEMP

TBS_SINGLE

。。。。。。。。。。。。。。。。。

13 rows selected.

SQL> conn tranp/oracle

Connected.

SQL> select * from tab;

TNAME TABTYPE CLUSTERID

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

T01 TABLE

SQL> select count(*) from t01;

COUNT(*)

----------

49795

SQL> conn / as sysdba

Connected.

SQL> select TABLESPACE_NAME,STATUS from dba_tablespaces;

TABLESPACE_NAME STATUS

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

SYSTEM ONLINE

UNDOTBS1 ONLINE

SYSAUX ONLINE

TEMP ONLINE

。。。。。。。。。。。。。。。。。。。。。。。。

a元數據庫：

SQL> select tab1.aa||'_'||tab2.bb||'.'||tab3.cc from

2 (select VALUE$ aa from sys.props$ where name='NLS_LANGUAGE')tab1,

3 (select VALUE$ bb from sys.props$ where name='NLS_ISO_CURRENCY')tab2,

b目標數據庫：

SQL> select tab1.aa||'_'||tab2.bb||'.'||tab3.cc from

2 (select VALUE$ aa from sys.props$ where name='NLS_LANGUAGE')tab1,

3 (select VALUE$ bb from sys.props$ where name='NLS_ISO_CURRENCY')tab2,

4 (select VALUE$ cc from sys.props$ where name='NLS_CHARACTERSET')tab3;

TAB1.AA||'_'||TAB2.BB||'.'||TAB3.CC

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

AMERICAN_AMERICA.AL32UTF8

原因：由于源和目標數據庫的字符集不一致或不是子集和超集的關系，所以造成不能導入表空間的字符集。

解決方法：將源數據庫和目標數據庫的字符集調整為一致的字符集；或者源數據庫的字符集是目標數據庫的子集。

源數據庫的修改：

SQL> alter database character set internal_use utf8;

alter database character set internal_use utf8
