使用RMAN duplicate database from file System to ASM
测试环境如下:
1.使用了恢复目录数据库jy
2.目标数据库test在主机oracle11g上，并且数据文件是存储在文件系统中
3.将目标数据库test复制到远程主机jingyong1上生成数据库dupdb。
4.主机jingyong1上有ASM磁盘组+dg1
5.将数据库dupdb的数据文件存储在磁盘组+dg1中
6.在磁盘组+dg1中存储两份控制文件
7.在主机oracle11g上创建的备份与归档重做日志必须能被主机jingyong1访问
执行步骤如下:
1.创建辅助实例的密码文件(这里辅助实例名为dupdb)
[oracle@jingyong1 dbs]$ orapwd file=/u01/app/oracle/product/10.2.0/db/dbs/orapwdupdb password=oracle entries=10 [oracle@jingyong1 dbs]$ ls -lrt orapwdupdb -rw-r----- 1 oracle oinstall 2560 Mar 25 20:49 orapwdupdb
2.创建辅助实例网络连接,修改监听文件，使用静态监听来监听辅助实例远程主机jingyong1
[oracle@jingyong1 admin]$ vi listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = dupdb)
(ORACLE_HOME =/u01/app/oracle/product/10.2.0/db)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.11)(PORT = 1521))
)
)
给辅助实例增加网络服务名
[oracle@jingyong1 admin]$ vi tnsnames.ora
dupdb =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.11)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =dupdb)
(UR=A)
)
)
在目标主机上给辅助实例增加网络服务名
[oracle@oracle11g admin]$ vi tnsnames.ora
dupdb =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.11)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =dupdb)
(UR=A)
)
)
测试网络连接
远程主机jingyong1
[oracle@jingyong1 admin]$ export ORACLE_SID=dupdb [oracle@jingyong1 admin]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Wed Mar 25 20:53:26 2015 Copyright (c) 1982, 2010, Oracle. All Rights Reserved. SQL> conn sys/oracle@dupdb as sysdba Connected to an idle instance.

3.创建辅助实例的参数文件
[oracle@jingyong1 dbs]$ vi initdupdb.ora
db_name=dupdb
db_unique_name=dupdb
control_files=('+DG1/control01.ctl','+DG1/control02.ctl')
db_file_name_convert=('/u01/app/oracle/oradata/test/','+DG1/')

db_block_size=8192
sga_target=160M

pga_aggregate_target=16M
[oracle@jingyong1 dbs]$ export ORACLE_SID=dupdb
[oracle@jingyong1 dbs]$ sqlplus / as sysdba

SQL> create spfile from pfile='/u01/app/oracle/product/10.2.0/db/dbs/initdupdb.ora';
File created.
4.启动辅助实例
[oracle@jingyong1 dbs]$ export ORACLE_SID=dupdb
[oracle@jingyong1 dbs]$ sqlplus / as sysdba

断开连接
SQL> exit Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - Production With the Partitioning, OLAP, Data Mining and Real Application Testing options
这里一定要断开启动辅助实例的会话否则在执行复制操作时会出现如下错误 ：
executing Memory Script RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of Duplicate Db command at 03/24/2015 18:28:32 RMAN-03015: error occurred in stored script Memory Script RMAN-06136: ORACLE error from auxiliary database: ORA-01013: user requested cancel of current operation
5.加载或打开目标数据库
[oracle@oracle11g ~]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Tue Mar 24 21:13:44 2015 Copyright (c) 1982, 2010, Oracle. All Rights Reserved.

6.确保有需要的备份和归档重做日志,对目标数据库（被复制的数据库）进行备份（包含数据文件和归档重做日志）

7.执行duplicate命令，如果没有配置自动通道，那么至少手动分配一个辅助实例如果是使用PFILE参数文件启动辅助实例需要指定pfile参数文件，且pfile参数文件必须存储在运行RMAN执行复制的主机上。这里辅助实例使用SPFILE参数文件来启动，并使用自动通道:
