使用duplicate target database ... from active database复制数据库
使用duplicate target database ... from active database复制数据库
source db：ora11
auxiliary db：dupdb
1.修改监听文件，静态注册监听
SID_LIST_ORA11 = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = ora11) (ORACLE_HOME = /u11/app/oracle/product/11.2.0/dbhome_1) (SID_NAME =ora11) ) (SID_DESC = (GLOBAL_DBNAME = dupdb) (ORACLE_HOME = /u11/app/oracle/product/11.2.0/dbhome_1) (SID_NAME =dupdb) ) )
2.修改tnsnames.ora文件
ORA11 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = mytest)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ora11) ) ) DUPDB = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = mytest)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = dupdb) ) )
3.为duplicate 数据库创建参数文件initdupdb.ora
db_name=dupdb
4.创建口令文件
$ orapwd password=<sys_pwd> file=orapwtest1 entries=20
5.启动auxiliary 库
$ sqlplus /nolog SQL*Plus: Release 11.2.0.1.0 Production on Fri Jun 26 12:28:26 2015 Copyright (c) 1982, 2009, Oracle. All rights reserved. SQL> conn /as sysdba Connected to an idle instance.

6.启动rman
$ rman Recovery Manager: Release 11.2.0.1.0 - Production on Fri Jun 26 12:31:07 2015 Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved.

7.执行duplicate target database ... from active database 命令开始duplicate操作

完成！
"active database duplication"过程完成的操作：
·数据文件从source库被copy到duplicate库
·重建控制文件；如果是standby库，控制文件会从source库拷贝到standby
·根据参数db_create_file_dest设置，重建temp文件
·重建online redo log
·根据需要，拷贝归档日志文件
·如果只是指定了spfile，会拷贝spfile文件
·standby库需要拷贝口令文件；如果只是duplicate库，看duplicate database命令是否指定
·快速闪回区不会被copy，闪回日志文件、口令文件和块改变跟踪文件不会被创建
