2.创建一个独立的自包含表空间

用于测试.

代码:


$ sqlplus "/ as sysdba"

5.确认导出文件已生成.

$ ls /tmp/data*

$ ls -l /tmp/data*
-rw-r----- 1 oracle dba 10493952 Apr 27 14:12 /tmp/data_D-EYGLE_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\vilen\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: VILEN (DBID=1587222708)


RMAN> CONVERT DATAFILE 'E:\Oracle\oradata\vilen\dpdata\data_D-EYGLE_I-1337390772_TS-TRANS_FNO-8_01fk92hg'

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\VILEN\DPDATA\DATA_D-EYGLE_I-1337390772_TS-TRANS_FNO-8_01FK92HG
已转换的数据文件 = E:\ORACLE\ORADATA\VILEN\VILEN\DATAFILE\TRANS01.DBF
通道 ORA_DISK_1: 数据文件转换完毕, 经过时间: 00:00:04

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\vilen\dpdata>impdp eygle/eygle dumpfile=trans.dmp directory=dpdata transport_datafiles='E:\Oracle\orad

9.检查数据

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

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

SQL> select count(*) from test;

COUNT(*)

1

SQL> exit
从 Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production

E:\Oracle\oradata\vilen\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.

然而这一简单改进带来的方便之处是显而易见的.
