利用imp/impdp传输表空间transport_tablespace满足以下条件
1.字符集相同
2.要导出的表空间必须是read only,而且是自包含的，就是说该表空间的对象不能依赖其他表空间。
3.先导出源数据，传输表空间的数据文件拷贝到另一个数据库相应目录下。
而RMAN不需要表空间READ ONLY，因为它是备份集进行传输，但是也需要字符集相同和自包含。
下面基于RMAN传输表空间的测试。
测试环境
源数据库：
OS=RHEL 6.4;
DB=ORACLE11GR2 ;
IP=192.168.1.171;
SID=hjj;
ASM存储。
目标数据库：
OS=WIN7 64BIT;
DB=ORACLE11GR2;
IP=192.168.1.1;
SID=orcl;
FS存储。
一、在源数据库端
1.创建测试表空间
SQL> create tablespace tt1 datafile '+DATA_DG/hjj/datafile/test01.dbf' size 100m;


Tablespace created.
2.创建用户并授权
SQL> create user tt1 identified by oracle default tablespace tt1;


User created.


SQL> grant connect,resource to tt1;


Grant succeeded.
3.创建测试表
SQL> create table tt1.t as select * from dba_objects;


Table created.
4.查看数据
SQL> conn tt1/oracle
Connected.
SQL> select count(*) from t;


  COUNT(*)
----------
     21293
4.确认传输表空间的平台是否兼容
在源数据库端：
SQL> select tp.* from v$transportable_platform tp,v$database d where tp.PLATFORM_NAME = d.PLATFORM_NAME;


PLATFORM_ID PLATFORM_NAME                                      ENDIAN_FORMAT
----------- -------------------------------------------------- --------------
         10 Linux IA (32-bit)                                  Little
在目标数据库端：
SQL> select tp.* from v$transportable_platform tp,v$database d where tp.PLATFORM_NAME = d.PLATFORM_NAME;


PLATFORM_ID PLATFORM_NAME                                      ENDIAN_FORMAT
----------- -------------------------------------------------- ----------------------------
         12 Microsoft Windows x86 64-bit                       Little
可以看到windows平台和linux都是Little，是兼容的。
5.确认源数据库的表空间是否自包含
SQL> exec dbms_tts.transport_set_check('tt1',true,true);


PL/SQL procedure successfully completed.


SQL> select * from transport_set_violations;


no rows selected
6.备份源数据库
[oracle@myrac1 ~]$ rman target sys/oracle@hjj catalog rman/rman

说明：这里使用全库备份，因为除了目标表空间的备份以外，RMAN还需要SYSTEM、SYSAUX以及UNDO表空间的备份，如果任意一个表空间的备份不存在，则就会导致“RMAN-06019: 无法转换表空间名称"TTB1"”的错误。

tt01.dbf --数据文件，可以发现生成的数据文件和原来的数据文件一模一样。
HJJ是/s01/dd下的一个临时目录。


8.目标数据库中导入元数据集
a.使用asm存储体系，使用dump导入
convert datafile '/opt/tts/td/tts.288.755520393' format '+datagroup';
如果是使用的asm则需要把os上面的文件放到asm里面，上面这条命令可以在os和asm之间转换数据文件。
impdp system/oracle@orcl directory=dp dumpfile=dmpfile.dmp nologfile=y transport_datafiles='+DATAGROUP/ORCL/DATAFILE/TTS.290.755528197';
b.使用文件系统，使用dump导入。
impdp system/oracle@orcl directory=dp dumpfile=dmpfile.dmp nologfile=y transport_datafiles='/opt/oradata/tts.288.755520393';
c.@/opt/tts/td/impsctpt.sql
9.复制源数据库/s01/dd目录和数据文件到目标数据库D:\dd
D:\dd>ls
dmpfile.alg   dmpfile.dmp   impscrpt.sql  tt01.dbf
10.检查源数据库和目标数据库的数据块大小是否一致
源数据库：
SQL> select block_size from dba_tablespaces where tablespace_name = 'TT1'; 


BLOCK_SIZE
----------
      8192
目标数据库：
SQL> show parameter db_block_size


NAME                                 TYPE                   VALUE
------------------------------------ ---------------------- ---------
db_block_size                        integer                8192
11.在目标数据上创建用户

impdp执行，你可以运行impscrpt.sql，也是成功。因为两种方式报的错误都是一样的。

目标端导入的表空间默认是READ-ONLY；将表空间改为READ WRITE
SQL> select tablespace_name,status from dba_tablespaces where tablespace_name = 'TT1';

至此表空间从linux ASM磁盘组迁移到win FS系统下。
遇到的问题以及注意项
1.源数据库表空间的名字不能为test，因为test是RMAN的关键字。
RMAN> transport tablespace test tablespace destination "/s01/dd" auxiliary destination "/s01/dd";


RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00558: error encountered while parsing input commands

http://docs.oracle.com/cd/B19306_01/backup.102/b14194/rcmcomma001.htm#RCMRF909有说明
2.如果两个平台的字节顺序不一致，可以使用rman进行转化。
RMAN> convert tablespace tt1 to platform 'Microsoft Windows IA (32-bit)' format '/tmp/%N_%F';   
RMAN> convert datafile '/tmp/BOOKS_5' db_file_name_convert '/tmp/BOOKS_5','/tmp/books01.dbf';  
3.创建传输集过程报错如下
ORA-19502: write error on file "/s01/dd/HJJ/datafile/o1_mf_system_9kj14qc1_.dbf", block number 82816 (block size=8192)
ORA-27072: File I/O error

ORA-01110: data file 1: '+DATA_DG/hjj/datafile/system.260.837919351'
因为创建传输集时，需要一个临时目录/s01/dd，会将备份集中的datafile，onlinelog，controlfile存放于此，所以要提前估算好空间。
这个错误就是因为空间不足引起的。
