用户管理的热备份方式复制数据库
1. 创建实例, 密码文件, 初始化参数文件, 以及目标库相应目录
> oradim -new -sid dup （Windows下需要）
> orapwd file=pwddup password=xxxxxx（Windows下需要）
> mkdir %ORACLE_BASE%\admin\dup
> mkdir %ORACLE_BASE%\admin\dup\adump
> mkdir %ORACLE_BASE%\admin\dup\bdump
> mkdir %ORACLE_BASE%\admin\dup\cdump
> mkdir %ORACLE_BASE%\admin\dup\udump
2. 在源库开始热备份, 并复制数据文件到目标库目录
GO> alter database begin backup;
3. 源库停止热备份
GO> alter database end backup;
4. 归档源库当前日志, 并拷贝到目标库归档目录
GO> select * from v$log;
GROUP# SEQUENCE# ARC STATUS
---------- --------- --- --------
1 10 YES ACTIVE
2 11 NO CURRENT
3 9 YES INACTIVE
GO> alter system archive log current;
5. 将目标库启动到 nomount 状态, 并创建控制文件
DUP> startup nomount

6. 对目标库做介质恢复
DUP> recover database using backup controlfile until cancel;
ORA-00279: change 2521364 generated at 09/23/2012 16:04:19 needed for thread 1
ORA-00289: suggestion : D:\DATA\ORACLE10GR2\FLASH_RECOVERY_AREA\DUP\ARCHIVELOG\2012_09_23\O1_MF_1_10_%U_.ARC
ORA-00280: change 2521364 for thread 1 is in sequence #10

...
Specify log: {
cancel
Media recovery cancelled.
7. 以 resetlogs 方式打开目标库
DUP> alter database open resetlogs;
8. 添加临时文件到目标库
DUP> alter tablespace temp add tempfile 'D:\Data\oracle10gr2\dup\temp01.dbf' size 5m reuse;
DUP> select file#,name from v$tempfile;
FILE# NAME
---------- ----------------------------------------
1 D:\DATA\ORACLE10GR2\DUP\TEMP01.DBF
9. 修改目标库DBID
DUP> select dbid,name from v$database;
DBID NAME
---------- ----------------------------------------

DUP> shutdown immediate
DUP> startup mount
> nid target=sys/oracle
