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

Redo Buffers                 bytes

6.启动rman

$ rman

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
> spfile
>      parameter_value_convert='/u11/app/oracle/oradata/ora11','/u11/app/oracle/oradata/dupdb'
>      set
>              log_file_name_convert='/u11/app/oracle/oradata/ora11','/u11/app/oracle/oradata/dupdb'
>              db_file_name_convert='/u11/app/oracle/oradata/ora11','/u11/app/oracle/oradata/dupdb';

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
