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./dbhome_1)
(SID_NAME =ora11)
)
(SID_DESC =
(GLOBAL_DBNAME = dupdb)
(ORACLE_HOME = /u11/app/oracle/product/11.2./dbhome_1)
(SID_NAME =dupdb)
)
)
2.修改tnsnames.ora文件
ORA11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = mytest)(PORT = ))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora11)
)
) DUPDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = mytest)(PORT = ))
)
(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=
5.启动auxiliary 库
$ sqlplus /nolog SQL*Plus: Release 11.2.0.1. Production on Fri Jun :: Copyright (c) , , Oracle. All rights reserved. SQL> conn /as sysdba
Connected to an idle instance.
SQL> startup nomount pfile='/u11/app/oracle/product/11.2.0/dbhome_1/dbs/initdupdb.ora';
ORACLE instance started. Total System Global Area bytes

6.启动rman
$ rman Recovery Manager: Release 11.2.0.1. - Production on Fri Jun :: Copyright (c) , , Oracle and/or its affiliates. All rights reserved. RMAN> connect target sys/oracle@ora11 connected to target database: ORA11 (DBID=) RMAN> connect auxiliary / connected to auxiliary database: DUPDB (not mounted) RMAN>
7.执行duplicate target database ... from active database 命令开始duplicate操作
RMAN> duplicate target database to dupdb from active database

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
