使用duplicate target database ... from active database復制數據庫
source db：ora11
auxiliary db：dupdb
1.修改監聽文件，靜態注冊監聽
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.為duplicate 數據庫創建參數文件initdupdb.ora
db_name=dupdb
4.創建口令文件
$ orapwd password=<sys_pwd> file=orapwtest1 entries=20
5.啟動auxiliary 庫
$ 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.啟動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. RMAN> connect target sys/oracle@ora11 connected to target database: ORA11 (DBID=785451981) RMAN> connect auxiliary / connected to auxiliary database: DUPDB (not mounted) RMAN>
7.執行duplicate target database ... from active database 命令開始duplicate操作
RMAN> duplicate target database to dupdb from active database
2> spfile
3> parameter_value_convert='/u11/app/oracle/oradata/ora11','/u11/app/oracle/oradata/dupdb'
4> set
5> log_file_name_convert='/u11/app/oracle/oradata/ora11','/u11/app/oracle/oradata/dupdb'
6> db_file_name_convert='/u11/app/oracle/oradata/ora11','/u11/app/oracle/oradata/dupdb';

完成！
"active database duplication"過程完成的操作：
·數據文件從source庫被copy到duplicate庫
·重建控制文件；如果是standby庫，控制文件會從source庫拷貝到standby
·根據參數db_create_file_dest設置，重建temp文件
·重建online redo log
·根據需要，拷貝歸檔日志文件
·如果只是指定了spfile，會拷貝spfile文件
·standby庫需要拷貝口令文件；如果只是duplicate庫，看duplicate database命令是否指定
·快速閃回區不會被copy，閃回日志文件、口令文件和塊改變跟蹤文件不會被創建
