一.3 相关知识点扫盲
可传输表空间的特性主要用于进行库对库的表空间复制，要进行传输的表空间必须置于read-only模式。如果生产库不允许表空间置为只读模式，没关系，方法还是有的，通过RMAN备份也可以创建可传输表空间集。要使用可传输表空间的特性，oracle至少是8i企业版或更高版本。如果是相同操作系统平台相互导入，则8i及以上版本均可支持，但如果是不同操作系统平台，数据库版本至少10g。被传输的表空间即可以是字典管理，也可以是本地管理。并且自oracle9i开始，被传输表空间的block size可以与目标数据库的block size不同。
可传输表空间(还有个集)最大的优势是其速度比export/import或unload/load要快的多。因为可传输表空间主要是复制数据文件到目标路径，然后再使用export/import或Data Pump export/import等应用仅导出/导入表空间对象的元数据到新数据库。
关于可传输表空间，还有个集(Transportable Tablespace Sets)的创建，其中都提到了很重要一点，就是被传输的表空间在传输过程中必须置为 read-only。而在实际操作过程中，对于某些生产数据库，将表空间置为 read-only 是件非常复杂的事情甚至完全不允许，有了 RMAN 的 Transportable Tablespace，这一切都得以避免。RMAN 通过备份创建可传输表空间集，它并不需要存取活动的数据文件，相应也就不需要将表空间置为 read-only。因此，数据库可用性得到提升，尤其对于超大的表空间，因为被传输的表空间在此期间仍可进行读写操作，而且把表空间置为 read-only 模式可能会花费较长时间，
使用 RMAN 创建可传输表空间集，允许你在传输过程中指定目标恢复时间点或 SCN，这样传输的数据可以更灵活，不必完全复制现有表空间，只要备份中存在，你就可以选择性的恢复数据。例如，你的备份策略为保留一周，你希望创建的可传输表空间中数据是截止本月底最后一天的数据，那么你在下个月第一周内任何时候都可以进行传输操作而不需要考虑这期间生产库是否会有写入操作。
一.3.1 注意事项
☞ 注意：
① source和target database的数据库版本最好一致，否则会因为db time zone 不一致导致报如下错误，但是如果source大于等于target的话是可以的，向下兼容的
ORA-39002: invalid operation
ORA-39322: Cannot use transportabletablespace with timestamp with timezone columns and different timezone version.
② source和target端的字符集必须一致，例如如下情况报错：
source为 ZHS16GBK，target为AL32UTF8
ORA-39123: Data Pump transportable tablespace job aborted
ORA-29345: cannot plug a tablespace into a database using an incompatible character set
Tartget db char set AL32UTF8 is not a superset of ZHS16GBK.
Failed to plug in a tablespace due to incompatible
database character set"AL32UTF8" and
transportable set database character set "ZHS16GBK"
③ source和target database的compatible 参数最好一致，但source如果小于等于target端的话是可以的，例如source为11.2.0.4.0，target为11.2.0.0.0就不行，impdp的时候报错：
ORA-39123: Data Pump transportable tablespace job aborted
ORA-00721: changes by release 11.2.0.4.0 cannot be used by release 11.2.0.0.0

一.4.2 实验目标
要实现将自定义的应用程序表空间app1tbs,app2tbs,idxtbs从源平台传递到目标平台，而在实际的工作过程中，需要将AIX上的数据库迁移到Linux，或者将Linux上的数据库迁移到AIX上，除了exp/imp和expdp/impdp外，最常用的就是传输表空间了，若是整个库迁移的话，我们需要做的就是把业务用户和业务表空间的数据迁移过来就行，Undo、temp、system等等的就不用迁移了，整个处理过程和本文档的处理过程大同小异，需要关注的是业务对象的个数、大小、状态等。

一.6 判断平台支持并确定字节序
如果传输表空间集到不同的平台，则要确定对于源和目标平台这种跨平台表空间被支持，也要确定每个平台的字节序，如果平台具有相同的字节序，则不需要进行转化，否则必须做一个表空间集转化，在源端或目标端都可以，在源端用convert tablespace，在目标端用convert datafile。
SYS@ora11g> col platform_name for a40
SYS@ora11g> select tp.platform_name, tp.endian_format
2 from v$transportable_platform tp
3 where tp.platform_name in ('Linux x86 64-bit', 'AIX-Based Systems (64-bit)');
PLATFORM_NAME ENDIAN_FORMAT
---------------------------------------- ----------------------------
AIX-Based Systems (64-bit) Big
Linux x86 64-bit Little
SQL>
源平台和目标平台的Endian_format 不同，source端为Big，target端为Little，所以需要进行表空间集转换，前边说过在源端或目标端都可以进行转换，这里我们选择在目标端来进行转换。
一.7 选择自包含的表空间集
一.7.1 进行检查
Indicates whether a full or partial dependency check is required. If TRUE, treats all IN and OUT pointers(dependencies) and captures them as violations if they are not self-contained in the transportable set.
execute sys.dbms_tts.transport_set_check('app1tbs,app2tbs,idxtbs',true);
select * from sys.transport_set_violations;
先试试要传输app1tbs和idxtbs这2个表空间：
SYS@ora11g> execute sys.dbms_tts.transport_set_check('app1tbs,idxtbs',true);
PL/SQL procedure successfully completed.
SQL> col violations for a70
SYS@ora11g> select * from sys.transport_set_violations;
VIOLATIONS
----------------------------------------------------------------------
ORA-39907: Index USER_APP2.IDX_DEPT_DNAME in tablespace IDXTBS points
to table USER_APP2.APP2_TAB in tablespace APP2TBS.
SQL>
结论： 在idxtbs表空间中IDX_DEPT_DNAME索引指向了表空间集外的user_app2.APP2_TAB表，所以这里选择app1tabs,app2tabs,idxtbs作为新的表空间集再次进行检查
SYS@ora11g> execute sys.dbms_tts.transport_set_check('app1tbs,app2tbs,idxtbs',true);
PL/SQL procedure successfully completed.
SYS@ora11g> select * from sys.transport_set_violations;
no rows selected
SYS@ora11g>
结论： 此时这个表空间集已经不在违背自包含的条件，可以确定为一个可传输表空间集
一.8 产生可传输表空间集
一.8.1 使自包含的表空间集中的所有表空间变为只读状态
SYS@ora11g> alter tablespace app1tbs read only;

SYS@ora11g> alter tablespace app2tbs read only;

一.12 target端开始导入数据
一.12.1 创建source库的2个用户并赋权限
如果不创建用户会报如下的错误：
ORA-39123: Data Pump transportable tablespace job aborted
ORA-29342: user USER_APP1 does not exist in the database
create user user_app1 identified by user_app1;
create user user_app2 identified by user_app2;
grant connect , resource to user_app1;
grant connect , resource to user_app2;
SYS@orclasm> create user user_app1 identified by user_app1;
User created.
SYS@orclasm> create user user_app2 identified by user_app2;
User created.
SYS@orclasm> grant connect , resource to user_app1;
Grant succeeded.
SYS@orclasm> grant connect , resource to user_app2;
Grant succeeded.
SYS@orclasm> exit
一.12.2 开始导入
导入元数据，注意这里的TRANSPORT_DATAFILES为转换后的新文件名称：

一.13 总结
到此所有的处理算是基本完毕，过程很简单，但是不同的场景处理方式有很多种，我们应该学会灵活变通。
