2.创建一个独立的自包含表空间

用于测试

$ sqlplus "/ as sysdba"

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'

Copyright (c) 1995, 2004, Oracle. All rights reserved.

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

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

 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

Copyright (c) 1995, 2004, Oracle. All rights reserved.

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

Copyright (c) 2003, Oracle. All rights reserved.

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:\

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

Copyright (c) 1982, 2004, Oracle. All rights reserved.

 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.
