0、准备工作
--创建被传输的表空间
SQL> create tablespace tbs_single
datafile 'c:\oracle\oradata\ora9i\tbs_single01.dbf' size 100M
extent management local;
--创建用户，并将表空间作为默认表空间
SQL> create user tranp identified by oracle default tablespace tbs_single;
SQL> grant connect,resource to tranp;
--在该表空间创建表，用于测试
SQL> create table tranp.t01 as select * from sys.dba_objects;
1、检查源、目标平台Endianness
在源数据库平台上：
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
在目标数据库平台上：
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
由于源和目标平台的Endianness一致，可以省去convert这一步。
2、检查要表空间是否自包含
SQL> EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK('TBS_SINGLE',true);
PL/SQL 过程已成功完成。
SQL> SELECT * FROM TRANSPORT_SET_VIOLATIONS;
未选定行
说明表空间是自包含的。
3、产生传输表空间集
创建目录对象
SQL> create DIRECTORY tranp_dir as 'c:\software';
目录已创建。
SQL> grant read,write on DIRECTORY tranp_dir to public;
授权成功。
将表空间置为只读。
SQL> alter tablespace tbs_single read only;
表空间已更改。
使用数据泵导出传输表空间的元数据
注：如果Endianness不一致，还需要使用RMAN进行转换表空间的数据文件。
4、传送表空间集
将表空间的数据文件和导出的DMP文件，传送到目标数据库平台上。
5、导入表空间
在目标数据库中，创建相应的目录对象和用户。
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.
使用数据库泵，导入到目标数据库中。
[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
将被导入的表空间置为read write。
SQL> alter tablespace TBS_SINGLE read write;
Tablespace altered.
6、测试
目标库中，进行测试。
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元数据库：
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目标数据库：
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,

TAB1.AA||'_'||TAB2.BB||'.'||TAB3.CC
----------------------------------------------------------------------
AMERICAN_AMERICA.AL32UTF8
原因：由于源和目标数据库的字符集不一致或不是子集和超集的关系，所以造成不能导入表空间的字符集。
解决方法：将源数据库和目标数据库的字符集调整为一致的字符集；或者源数据库的字符集是目标数据库的子集。
源数据库的修改：
SQL> alter database character set internal_use utf8;
alter database character set internal_use utf8
