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

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 eygle/eygle dumpfile=trans.dmp directory=dpdata transport_tablespace=trans

LRM-00101: unknown parameter name 'transport_tablespace'

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

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

Connected to: Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - 64bit Production

With the Partitioning, OLAP and Data Mining options

Starting "EYGLE"."SYS_EXPORT_TRANSPORTABLE_01": eygle/******** dumpfile=trans.dmp directory=dpdata TRANSPORT_TABLESPACES=trans

ORA-39123: Data Pump transportable tablespace job aborted

ORA-29335: tablespace 'TRANS' is not read only

Job "EYGLE"."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

Job "EYGLE"."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: EYGLE (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-EYGLE_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-EYGLE_I-1337390772_TS-TRANS_FNO-8_01fk92hg

$ 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

220 billing-center.hurray.com.cn FTP server (SunOS 5.8) ready.

User (172.16.33.32none)): gqgai

331 Password required for gqgai.

Password:

ftp> bye

221 Goodbye.

7.使用rman在目标数据库转换文件

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

恢复管理器: 版本10.1.0.2.0 - Production

连接到目标数据库: EYGLE (DBID=1587222708)

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

2> DB_FILE_NAME_CONVERT

3> 'E:\Oracle\oradata\eygle\dpdata\data_D-EYGLE_I-1337390772_TS-TRANS_FNO-8_01fk92hg','E:\Oracle\oradata\eygle\EYGLE\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\EYGLE\DPDATA\DATA_D-EYGLE_I-1337390772_TS-TRANS_FNO-8_01FK92HG

已转换的数据文件 = E:\ORACLE\ORADATA\EYGLE\EYGLE\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\eygle\dpdata>impdp eygle/eygle dumpfile=trans.dmp directory=dpdata transport_datafiles='E:\Oracle\orad

ata\eygle\EYGLE\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 "EYGLE"."SYS_IMPORT_TRANSPORTABLE_01"

启动 "EYGLE"."SYS_IMPORT_TRANSPORTABLE_01": eygle/******** dumpfile=trans.dmp directory=dpdata transport_datafiles='E:\

Oracle\oradata\eygle\EYGLE\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 "EYGLE"."SYS_IMPORT_TRANSPORTABLE_01" 因致命错误于 15:02 停止

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

ata\eygle\EYGLE\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 "EYGLE"."SYS_IMPORT_TRANSPORTABLE_01"

启动 "EYGLE"."SYS_IMPORT_TRANSPORTABLE_01": eygle/******** dumpfile=trans.dmp directory=dpdata transport_datafiles='E:\

Oracle\oradata\eygle\EYGLE\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 "EYGLE"."SYS_IMPORT_TRANSPORTABLE_01" 已于 15:03 成功完成

9.检查数据

E:\Oracle\oradata\eygle\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(*)

----------

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\eygle\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.
