使用RMAN DUPLICATE DATABASE From ASM 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dupdb在主机jingyong1上，并且数据文件是存储在磁盘组+DG1中
3.将目标数据库dupdb复制到远程主机oracle11g上生成数据库dupcp。
4.主机oracle11g上有ASM磁盘组+DISK1
5.将数据库dupcp的数据文件存储在磁盘组+DISK1中
6.在磁盘组+DISK1中存储两份控制文件
7.在主机jingyong1上创建的备份与归档重做日志必须能被主机oracle11g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dupcp)
[oracle@oracle11g dbs]$ orapwd file=/u01/app/oracle/10.2.0/db/dbs/orapwdupcp password=oracle entries=10 [oracle@oracle11g dbs]$ ls -lrt orapwdupcp -rw-r----- 1 oracle oinstall 2560 Mar 25 22:05 orapwdupcp
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oracle11g
[oracle@oracle11g admin]$ vi listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = dupcp)
(ORACLE_HOME =/u01/app/oracle/10.2.0/db)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.2)(PORT = 1521))
)
)
给辅助实例增加网络服务名
[oracle@oracle11g admin]$ vi tnsnames.ora
dupcp =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.2)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =dupcp)
(UR=A)
)
)
在目标主机上给辅助实例增加网络服务名
[oracle@jingyong1 admin]$ vi tnsnames.ora
dupcp =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.11)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =dupcp)
(UR=A)
)
)
测试网络连接
远程主机oracle11g
[oracle@oracle11g admin]$ export ORACLE_SID=dupcp [oracle@oracle11g admin]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Wed Mar 25 22:14:49 2015 Copyright (c) 1982, 2010, Oracle. All Rights Reserved. SQL> conn sys/oracle@dupcp as sysdba Connected to an idle instance.
目标主机jingyong1

3.创建辅助实例的参数文件
[oracle@oracle11g dbs]$ vi initdupcp.ora
db_name=dupcp
db_unique_name=dupcp
control_files=('+DISK1/control01.ctl','+DISK1/control02.ctl')
db_file_name_convert=('+DG1/','+DISK1/')
log_file_name_convert=('+DG1/','+DISK1/')
remote_login_passwordfile=exclusive
compatible = 10.2.0.5.0
db_block_size=8192
sga_target=160M
sga_max_size=160M
pga_aggregate_target=16M
[oracle@oracle11g dbs]$ export ORACLE_SID=dupcp
[oracle@oracle11g dbs]$ sqlplus / as sysdba

SQL> create spfile from pfile='/u01/app/oracle/10.2.0/db/dbs/initdupcp.ora';
File created.
4.启动辅助实例
[oracle@oracle11g dbs]$ export ORACLE_SID=dupcp
[oracle@oracle11g dbs]$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.5.0 - Production on Wed Mar 25 22:22:12 2015

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@jingyong1 u02]$ export ORACLE_SID=dupdb [oracle@jingyong1 u02]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Tue Mar 24 21:13:44 2015 Copyright (c) 1982, 2010, Oracle.

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）
[oracle@jingyong1 dbs]$ rman target sys/oracle@dupdb catalog rman/rman@jy

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:
