4.运行RMAN DUPLICATE命令
登录到A机：
$ rman target sys/oracle@A auxiliary sys/oracle@B
RMAN> duplicate target database to testdb from active database;
具体过程如下：

5.打开辅助实例
登录到B机，
$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.4.0 Production on Thu Nov 5 16:06:29 2015 Copyright (c) 1982, 2013, Oracle. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production With the Partitioning, Real Application Clusters, OLAP, Data Mining and Real Application Testing options SQL> select status, instance_name from v$instance; STATUS INSTANCE_NAME ------------ ---------------- OPEN testdb SQL> select dbid, open_mode from v$database; DBID OPEN_MODE ---------- -------------------- 2678316385 READ WRITE |
至此，成功duplicate数据库TESTDB。可以发现使用RMAN DUPLICATE复制的数据库DBID是不同的。
