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:

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.

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。

这里是从10.2.0.5(源数据库的compatible参数为10.2.0.5.0)向10.2.0.4(这里目标数据库中的compatible参数却为10.2.0.3.0，不是10.2.0.4.0）跨平台传输表空间不会成功，也就是从高版本向低版本传输表空间不能成功。但从低版本向高版本传输表空间是可以成功，例如下面的示例：

为了从10.2.0.5向10.2.0.4(compatible=10.2.0.3.0)跨平台传输表空间，我这里测试一下将10.2.0.1源数据库升级到 10.2.0.5但compatible设置为10.2.0.1.0或小于目标数据库的compatible=10.2.0.3.0来进行测试。

可以看到，将源数据库10.2.0.5的compatible设置为10.2.0.3.0与目标数据库10.2.0.4的compatible一样，执行传输表空间是可以执行成功的。
之前使用pfile参数文件参源数据库的compatible参数从10.2.0.1.0修改为10.2.0.3.0了，现在将其修改为10.2.0.1.0，并重新使用pfile文件启动源数据库会报错。
[oracle@weblogic28 dbs]$ vi initjytest.ora 省.... *.compatible='10.2.0.1.0' SQL> startup pfile='/u01/app/oracle/product/10.2.0/db/dbs/initjytest.ora'; ORACLE instance started.

这也就证明从oracle 10g开始,compatible参数只能增大，不能缩小。
总结:
1.跨小版本执行跨平台与字节序的表空间传输时，源数据库的compatible参数必须小于或等于目标数据库的compatible参数
2.当源数据库的compatible参数大于目标数据库的compatible参数时，要执行跨平台与字节序的表空间传输只有将目标数据库升级为与源数据库相同的版本号且compatible参数要大于或等于源数据库的compatible参数。
3.从oracle 10g开始，compatible参数只能增大，不能缩小。
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$transportable_platform; PLATFORM_NAME ENDIAN_FORMAT -------------------------------------------------------------------------------- -------------- Solaris[tm] OE (32-bit) Big Solaris[tm] OE (64-bit) Big Microsoft Windows IA (32-bit) Little Linux IA (32-bit) Little AIX-Based Systems (64-bit) Big HP-UX (64-bit) Big HP Tru64 UNIX Little HP-UX IA (64-bit) Big Linux IA (64-bit) Little HP Open VMS Little Microsoft Windows IA (64-bit) Little IBM zSeries Based Linux Big Linux x86 64-bit Little Apple Mac OS Big Microsoft Windows x86 64-bit Little Solaris Operating System (x86) Little IBM Power Based Linux Big Solaris Operating System (x86-64) Little HP IA Open VMS Little
源平台:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux 64-bit for AMD Little
目标平台
SQL> select d.platform_name,endian_format from v$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.

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。

在将源数据库的compatible参数修改为10.2.0.3.0后无法启动数据库。
这里是从10.2.0.5(源数据库的compatible参数为10.2.0.5.0)向10.2.0.4(这里目标数据库中的compatible参数却为10.2.0.3.0，不是10.2.0.4.0）跨平台传输表空间不会成功，也就是从高版本向低版本传输表空间不能成功。但从低版本向高版本传输表空间是可以成功，例如下面的示例：
我们要将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$transportable_platform; PLATFORM_NAME ENDIAN_FORMAT -------------------------------------------------------------------------------- -------------- Solaris[tm] OE (32-bit) Big Solaris[tm] OE (64-bit) Big Microsoft Windows IA (32-bit) Little Linux IA (32-bit) Little AIX-Based Systems (64-bit) Big HP-UX (64-bit) Big HP Tru64 UNIX Little HP-UX IA (64-bit) Big Linux IA (64-bit) Little HP Open VMS Little Microsoft Windows IA (64-bit) Little IBM zSeries Based Linux Big Linux x86 64-bit Little Apple Mac OS Big Microsoft Windows x86 64-bit Little Solaris Operating System (x86) Little IBM Power Based Linux Big Solaris Operating System (x86-64) Little HP IA Open VMS Little
源平台:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux 64-bit for AMD Little
目标平台
SQL> select d.platform_name,endian_format from v$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.

可以看到，从10.2.0.1(compatible=10.2.0.1.0)向10.2.0.4(compatible=10.2.0.3.0)跨平台和字节序传输表空间是可以执行成功。
为了从10.2.0.5向10.2.0.4(compatible=10.2.0.3.0)跨平台传输表空间，我这里测试一下将10.2.0.1源数据库升级到 10.2.0.5但compatible设置为10.2.0.1.0或小于目标数据库的compatible=10.2.0.3.0来进行测试。

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.

可以看到，将源数据库10.2.0.5的compatible设置为10.2.0.3.0与目标数据库10.2.0.4的compatible一样，执行传输表空间是可以执行成功的。
之前使用pfile参数文件参源数据库的compatible参数从10.2.0.1.0修改为10.2.0.3.0了，现在将其修改为10.2.0.1.0，并重新使用pfile文件启动源数据库会报错。
[oracle@weblogic28 dbs]$ vi initjytest.ora 省.... *.compatible='10.2.0.1.0' SQL> startup pfile='/u01/app/oracle/product/10.2.0/db/dbs/initjytest.ora'; ORACLE instance started. Total System Global Area 1073741824 bytes Fixed Size 2101736 bytes Variable Size 335547928 bytes Database Buffers 729808896 bytes Redo Buffers 6283264 bytes ORA-00201: control file version 10.2.0.3.0 incompatible with ORACLE version 10.2.0.1.0 ORA-00202: control file: '/u01/app/oracle/oradata/jytest/control01.ctl'
这也就证明从oracle 10g开始,compatible参数只能增大，不能缩小。
总结:
1.跨小版本执行跨平台与字节序的表空间传输时，源数据库的compatible参数必须小于或等于目标数据库的compatible参数
2.当源数据库的compatible参数大于目标数据库的compatible参数时，要执行跨平台与字节序的表空间传输只有将目标数据库升级为与源数据库相同的版本号且compatible参数要大于或等于源数据库的compatible参数。
3.从oracle 10g开始，compatible参数只能增大，不能缩小。
