RMAN跨小版本跨平台与字节序传输表空间


将Linux平台上的源数据库中的tspitr与test表空间传输到AIX平台上。并在源主机上使用目录/u02/transport来存储被转换的数据文件。操作步骤如下:

1.将要被传输的表空间tspitr与test设置为只读
SQL> alter tablespace tspitr read only;

Tablespace altered.

SQL> alter tablespace test read only;

Tablespace altered.


2.检查源平台与目标平台信息支不支持传输操作
 数据库所支持的平台信息:
SQL> select platform_name,endian_format from v$transportable_platform;

PLATFORM_NAME                                                                    ENDIAN_FORMAT

源平台:
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.确认要被传输的表空间是否是自包含表空间(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


如果没有行选择,表示该表空间只包含表数据,可以传输。

4.记录表空间传输前表tspitr与test中的记录:
SQL> select count(*) from tspitr.tspitr;

  COUNT(*)
----------
    50315

SQL> select count(*) from test.test;

  COUNT(*)
----------
    50316


5.使用RMAN将源数据库中的表空间tspitr,test转换为目标平台字节序格式,使用format参数来控制被转换后数据文件的文件名和存储目录.

Grant succeeded.

出错原因是因为源数据库的compatible=10.2.0.5.0,目标数据库的compatible=10.2.0.3.0这里在导出使用version=10.2.0.3.0导出元数据后再执行导出也是同样会报这个错误,因为这里不是逻辑导出,而是传输表空间,所以version参数不起作用。所以想修改源数据库的compatible参数为10.2.0.3.0,但在10g以后,compatible参数只能增大不能减少。
SQL> show parameter compatible
