所谓active duplicate 是指该恢复是基于数据库自己文件的在线传输，
因此该操做对网络是有要求的，不过咱们的同一个机房中一般的百兆宽带，我想在数据库物理文件较大时，这种迁移方式，反而比拷贝备份文件来的更直接，更快速。web
个人两个测试虚机，配置好hostssql
[oracle@hdpdup admin]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.80.128 hdp.oracle.com
192.168.80.137 hdpdup
在hupdup 安装oracle软件（不建立instance），这个不具表。DBA都烂熟于心了。
在auxiliary database(辅助库)手动建好初始化参数文件，这里注意指定db_create_file_dest(这等于默认启用了OMF)
[oracle@hdpdup dbs]$ cat initorcl.ora
compatible ='11.2.0.0'
db_name=dup
db_create_file_dest='/u01/app/oracle/oradata/dup/datafile'
db_unique_name='dup'
control_files=/u01/app/oracle/oradata/dup/datafile/control01.ctl,/u01/app/oracle/oradata/dup/datafile/control02.ctl
[oracle@hdpdup admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
dup库添加静听，由于咱们如今没有实例，动态监听不能起来，因此咱们须要手动添加static listener
静态监听(注意一下静态监听的格式吧)数据库
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl_prd)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = hdpdup)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle
若是不配置静态监听，监听的状态是blocked，这样咱们的target database是没法链接上的windows
Service "dup" has 1 instance(s).
Instance "dup", status BLOCKED, has 1 handler(s) for this service...
The command completed successfully
确认一下监听的状态的变化哦ruby
Service "dup" has 1 instance(s).
Instance "dup", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
每一个节点这样设置的oracle network设置(由于咱们要让两个节点互通嘛)网络

RMAN> duplicate target database to dup from active database;
报错以下：dom
RMAN-06136: ORACLE error from auxiliary database: ORA-00201: control file version 11.2.0.4.0 incompatible with ORACLE version 11.2.0.0.0
ORA-00202: control file: '/u01/app/oracle/oradata/dup/datafile/control01.ctl'
因此咱们从新修改下svg
[oracle@hdpdup dbs]$ cat initdup.ora
compatible ='11.2.0.4'
db_name=dup
db_create_file_dest='/u01/app/oracle/oradata/dup/datafile'
db_unique_name='dup'
control_files=/u01/app/oracle/oradata/dup/datafile/control01.ctl,/u01/app/oracle/oradata/dup/datafile/control02.ctl
[oracle@hdpdup dbs]$
有一个报错，好像是由于我把user offline了，在拷贝的过程当中竟然rman主动尝试去drop了,这也算咱们get了新的技能点
删干净文件，而后从新来吧！
完整的脚本以下，咱们可能须要仔细研究一下以下的信息。

总结：
这和咱们在装11gR2 的DATAGUARD很是相似啊！
ORACLE是Linux/UNIX/windows平台的超级软件，其可配置性太强了，感受像是手动挡的超级跑车，又像是水果刀界的瑞士军刀(具体是这个界吗？)，哈哈，技术是学无止境的，所谓高手，大师，也不过是闻道有前后，术业有专攻而已，是否是这样呢？不知道，由于我即不是高手，也不是大师。
