2 FROM V$TRANSPORTABLE_PLATFORM tp, V$DATABASE d
3 WHERE tp.PLATFORM_NAME = d.PLATFORM_NAME;

PLATFORM_NAME ENDIAN_FORMAT
---------------------------------------- --------------

2.创建一个独立的自包含表空间

用于测试

$ sqlplus "/ as sysdba"

SQL*Plus: Release 10.1.0.2.0 - Production on Tue Apr 27 14:04:08 2004

Connected to:
Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options

SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/opt/oracle/oradata/wwl/system01.dbf
/opt/oracle/oradata/wwl/undotbs01.dbf
/opt/oracle/oradata/wwl/sysaux01.dbf
/opt/oracle/oradata/wwl/users01.dbf
/data1/oradata/systemfile/wwl01.dbf
/opt/oracle/oradata/wwl/wwl/datafile/o1_mf_test_03xv34ny_.dbf
/opt/oracle/oradata/wwl/wwl/datafile/o1_mf_itpub_03xv5g66_.dbf

7 rows selected.

SQL> create tablespace trans
2?datafile '/data1/oradata/systemfile/trans01.dbf'
3?size 10M;

Tablespace created.

SQL> create user trans identified by trans
2?default tablespace trans;

User created.

SQL> grant connect,resource to trans;

Grant succeeded.

SQL> connect trans/trans
Connected.

SQL> create table test as select * from user_objects;

Table created.

SQL> select count(*) from test;

COUNT(*)
----------
1

SQL> select * from test;

OBJECT_NAME
--------------------------------------------------------------------------------
SUBOBJECT_NAME?OBJECT_ID DATA_OBJECT_ID OBJECT_TYPE
------------------------------ ---------- -------------- -------------------
CREATED?LAST_DDL_TIM TIMESTAMP?STATUS?T G S
------------ ------------ ------------------- ------- - - -
TEST
15604?15604 TABLE
27-APR-04?27-APR-04?2004-04-27:14:05:42 VALID?N N N

SQL> exit
Disconnected from Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - 64bit Production
With the Partitioning, OLAP and Data

3.导出要传输的表空间

$ pwd
/opt/oracle
$ cd dpdata
$ ls
$ expdp wwl/wwl dumpfile=trans.dmp directory=dpdata transport_tablespace=trans
LRM-00101: unknown parameter name 'transport_tablespace'

$ expdp wwl/wwl dumpfile=trans.dmp directory=dpdata TRANSPORT_TABLESPACES=trans

Export: Release 10.1.0.2.0 - 64bit Production on Tuesday, 27 April, 2004 14:07

Job "wwl"."SYS_EXPORT_TRANSPORTABLE_01" stopped due to fatal error at 14:08

注意:传输表空间必须置为只读状态

$ sqlplus "/ as sysdba"

SQL*Plus: Release 10.1.0.2.0 - Production on Tue Apr 27 14:08:13 2004

Connected to:
Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options

SQL> alter tablespace trans read only;

Tablespace altered.

SQL> exit
Disconnected from Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options

$ expdp wwl/wwl dumpfile=trans.dmp directory=dpdata TRANSPORT_TABLESPACES=trans

Export: Release 10.1.0.2.0 - 64bit Production on Tuesday, 27 April, 2004 14:08

Connected to: Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
Starting "wwl"."SYS_EXPORT_TRANSPORTABLE_01": wwl/******** dumpfile=trans.dmp directory=dpdata TRANSPORT_TABLESPACES=trans
Processing object type TRANSPORTABLE_EXPORT/PLUGTS_BLK

Dump file set for wwl.SYS_EXPORT_TRANSPORTABLE_01 is:
/opt/oracle/dpdata/trans.dmp
Job "wwl"."SYS_EXPORT_TRANSPORTABLE_01" successfully completed at 14:09

4.使用rman转换文件格式

$ rman target /

Recovery Manager: Release 10.1.0.2.0 - 64bit Production

connected to target database: wwl (DBID=1337390772)

RMAN> convert tablespace trans
2> to platform 'Microsoft Windows IA (32-bit)'
3> Format '/tmp/%U';

Starting backup at 27-APR-04
using target database controlfile instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=148 devtype=DISK
channel ORA_DISK_1: starting datafile conversion
input datafile fno=00008 name=/data1/oradata/systemfile/trans01.dbf
converted datafile=/tmp/data_D-wwl_I-1337390772_TS-TRANS_FNO-8_01fk92hg
channel ORA_DISK_1: datafile conversion complete, elapsed time: 00:00:01
Finished backup at 27-APR-04

RMAN> exit

Recovery Manager complete.

5.确认导出文件已生成

$ ls /tmp/data*
/tmp/data_D-wwl_I-1337390772_TS-TRANS_FNO-8_01fk92hg
$ ls -l /tmp/data*
-rw-r----- 1 oracle dba 10493952 Apr 27 14:12 /tmp/data_D-wwl_I-1337390772_TS-TRANS_FNO-8_01fk92hg
$ chmod 777 /tmp/data*
$ chmod 777 /opt/oracle/dpdata/*

6.通过ftp传输文件至目标主机

220 billing-center.hurray.com.cn FTP server (SunOS 5.8) ready.
User (192.168.96.10none)): gqgai
331 Password required for gqgai.

226 Binary Transfer complete.
ftp: 73728 bytes received in 0.03Seconds 2457.60Kbytes/sec.
ftp> bye
221 Goodbye.

7.使用rman在目标数据库转换文件

E:\Oracle\oradata\wwl\dpdata>rman target /

恢复管理器: 版本10.1.0.2.0 - Production

连接到目标数据库: wwl (DBID=1587222708)

RMAN> CONVERT DATAFILE 'E:\Oracle\oradata\wwl\dpdata\data_D-wwl_I-1337390772_TS-TRANS_FNO-8_01fk92hg'
2> DB_FILE_NAME_CONVERT
3> 'E:\Oracle\oradata\wwl\dpdata\data_D-wwl_I-1337390772_TS-TRANS_FNO-8_01fk92hg','E:\Oracle\oradata\wwl\wwl\DATAFILE\trans01.dbf';

启动 backup 于 27-4月 -04
使用通道 ORA_DISK_1
通道 ORA_DISK_1: 启动数据文件转换
输出文件名=E:\ORACLE\ORADATA\wwl\DPDATA\DATA_D-wwl_I-1337390772_TS-TRANS_FNO-8_01FK92HG
已转换的数据文件 = E:\ORACLE\ORADATA\wwl\wwl\DATAFILE\TRANS01.DBF
通道 ORA_DISK_1: 数据文件转换完毕, 经过时间: 00:00:04
完成 backup 于 27-4月 -04

RMAN>

8.在目标数据库plugin数据文件

注意目标数据库中的目标用户必须存在,否则会报错.

E:\Oracle\oradata\wwl\dpdata>impdp wwl/wwl dumpfile=trans.dmp directory=dpdata transport_datafiles='E:\Oracle\orad
ata\wwl\wwl\DATAFILE\TRANS01.DBF'

Import: Release 10.1.0.2.0 - Production on 星期二, 27 4月, 2004 15:02

连接到: Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options
已成功加载/卸载了主表 "wwl"."SYS_IMPORT_TRANSPORTABLE_01"
启动 "wwl"."SYS_IMPORT_TRANSPORTABLE_01": wwl/******** dumpfile=trans.dmp directory=dpdata transport_datafiles='E:\
Oracle\oradata\wwl\wwl\DATAFILE\TRANS01.DBF'
处理对象类型 TRANSPORTABLE_EXPORT/PLUGTS_BLK
ORA-39123: 数据泵可传输的表空间作业中止
ORA-29342: 数据库中不存在用户 TRANS

作业 "wwl"."SYS_IMPORT_TRANSPORTABLE_01" 因致命错误于 15:02 停止

E:\Oracle\oradata\wwl\dpdata>sqlplus "/ as sysdba"

SQL*Plus: Release 10.1.0.2.0 - Production on 星期二 4月 27 15:03:03 2004

连接到:
Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options

SQL> create user trans identified by trans;

用户已创建。

SQL> grant connect,resource to trans;

授权成功。

SQL> exit
从 Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options 断开

E:\Oracle\oradata\wwl\dpdata>impdp wwl/wwl dumpfile=trans.dmp directory=dpdata transport_datafiles='E:\Oracle\orad
ata\wwl\wwl\DATAFILE\TRANS01.DBF'

Import: Release 10.1.0.2.0 - Production on 星期二, 27 4月, 2004 15:03

连接到: Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options
已成功加载/卸载了主表 "wwl"."SYS_IMPORT_TRANSPORTABLE_01"
启动 "wwl"."SYS_IMPORT_TRANSPORTABLE_01": wwl/******** dumpfile=trans.dmp directory=dpdata transport_datafiles='E:\
Oracle\oradata\wwl\wwl\DATAFILE\TRANS01.DBF'
处理对象类型 TRANSPORTABLE_EXPORT/PLUGTS_BLK
处理对象类型 TRANSPORTABLE_EXPORT/TABLE
处理对象类型 TRANSPORTABLE_EXPORT/TTE_POSTINST/PLUGTS_BLK
作业 "wwl"."SYS_IMPORT_TRANSPORTABLE_01" 已于 15:03 成功完成

9.检查数据

E:\Oracle\oradata\wwl\dpdata>sqlplus trans/trans

SQL*Plus: Release 10.1.0.2.0 - Production on 星期二 4月 27 15:03:50 2004

连接到:
Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options

SQL> select count(*) from test;

COUNT(*)
----------
1

SQL> exit
从 Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options 断开

E:\Oracle\oradata\wwl\dpdata>

可以选择把表空间更改为读写

SQL> alter tablespace trans read write;

表空间已更改。

10.总结

10g的表空间跨平台迁移，，较9i就是增加了一个使用Rman进行的文件格式转换的过程.
实际上也就是转换了数据文件头的格式信息而已.
