一，创建所需目录

1）创建审计文件目录

PROD1@dbrac1  /dsg/oracle11$ cd $ORACLE_BASE/admin
PROD1@dbrac1  /u01/app/oracle/admin$ mkdir -p PROD1/adump

2）创建数据文件目录

mkdir -p /dsg/oracle11/PROD1

二，创建参数文件和密码文件

这里，复制主库的参数文件和密码文件，参数文件稍作修改

PROD1@dbrac1  /dsg$ export ORACLE_SID=PROD
PROD@dbrac1  /dsg$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Tue Apr 29 14:00:54 2014

PROD@dbrac1  /dsg$ cd $ORACLE_HOME/dbs
PROD@dbrac1  /u01/app/oracle/product/11.2.0/dbs$ cp initPROD.ora initPROD1.ora
#复制密码文件
PROD@dbrac1  /u01/app/oracle/product/11.2.0/dbs$ cp orapwPROD orapwPROD1

修改参数文件

PROD1.__db_cache_size=272629760
PROD1.__java_pool_size=4194304
PROD1.__large_pool_size=4194304
PROD1.__oracle_base=‘/u01/app/oracle‘#ORACLE_BASE set from environment
PROD1.__pga_aggregate_target=3812622336
PROD1.__sga_target=536870912
PROD1.__shared_io_pool_size=0
PROD1.__shared_pool_size=243269632
PROD1.__streams_pool_size=0
*.audit_file_dest=‘/u01/app/oracle/admin/PROD1/adump‘
*.audit_trail=‘db‘
*.compatible=‘11.2.0.0.0‘
*.control_files=‘/dsg/oracle11/PROD1/control01.ctl‘,‘/dsg/oracle11/PROD1/control02.ctl‘
*.db_block_size=32768
*.DB_NAME=‘PROD1‘    ###如果辅助实例在同一台服务器上，DB_NAME不能相同
*.DB_UNIQUE_NAME=‘PROD1‘
*.diagnostic_dest=‘/u01/app/oracle‘
*.dispatchers=‘(PROTOCOL=TCP) (SERVICE=PROD1XDB)‘
*.LOG_ARCHIVE_FORMAT=‘log%t_%s_%r.arc‘

*.processes=150
*.REMOTE_LOGIN_PASSWORDFILE=‘EXCLUSIVE‘
*.sga_target=536870912
*.STANDBY_FILE_MANAGEMENT=‘AUTO‘
*.undo_tablespace=‘UNDOTBS1‘

###下面两个参数可选，但是推荐使用，如果不使用可以在rman的run块中指定恢复的目录
*.DB_FILE_NAME_CONVERT=‘/dsg/oracle11/PROD‘,‘/dsg/oracle11/PROD1‘
*.LOG_FILE_NAME_CONVERT=‘/dsg/oracle11/PROD‘,‘/dsg/oracle11/PROD1‘

三，配置监听及TNS

这里，使用静态监听

vi listener.ora 
 (ADDRESS_LIST=
      (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.70)(PORT=1521))
      (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))

SID_LIST_LISTENER=
  (SID_LIST=
      (SID_DESC=
         (GLOBAL_DBNAME=PROD)
         (SERVICE_NAME = PROD)
         (SID_NAME=PROD)
         (ORACLE_HOME=/u01/app/oracle/product/11.2.0)
        (PRESPAWN_MAX=20)
        (PRESPAWN_LIST=
          (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))
        )
       )
        (SID_DESC=
         (GLOBAL_DBNAME=PROD1)
         (SERVICE_NAME = PROD1)
         (SID_NAME=PROD1)
         (ORACLE_HOME=/u01/app/oracle/product/11.2.0)
        (PRESPAWN_MAX=20)
        (PRESPAWN_LIST=
          (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))
        )
       )
 )

tnsnames.ora添加

PROD =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.70)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = PROD)
    )
  )

PROD1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.70)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = PROD1)
    )
  )
 
####重启监听
lsnrctl reload

确认，

PROD@dbrac1  /home/oracle$ tnsping prod

四，启动辅助实例

启动辅助实例到nomount模式，也只能启动到nomount，一定要使用spfile参数文件

PROD@dbrac1  /home/oracle$ export ORACLE_SID=PROD1

PROD1@dbrac1  /home/oracle$ sqlplus  / as sysdba

五，rman连接TARGET和AUXILLARY实例，采用全字符串连接

六，总结及遇到的问题

1，在rman中恢复的时候总是报数据库名不一致，原来在同一个服务器上db_name不能相同且必须使用spfile

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of Duplicate Db command at 04/29/2014 15:21:38
RMAN-05520: database name mismatch, auxiliary instance has PROD, command specified PROD1

2，如果目标库与副本数据库的在线日志文件和数据文件路径不相同，则需要像本文一样配置db_file_name_convert和log_file_name_convert，否则会报错rman-06023

3，要是不配置db_file_name_convert和log_file_name_convert，可以通过如下命令达到相同的目的

RUN

{

  # The DUPLICATE command uses an automatic sbt channel.

  # Because the target datafiles are spread across multiple directories, 

  # run SET NEWNAME rather than DB_FILE_NAME_CONVERT

  SET NEWNAME FOR DATAFILE 1 TO ‘/oradata1/system01.dbf‘; 

  SET NEWNAME FOR DATAFILE 2 TO ‘/oradata2/undotbs01.dbf‘; 

  SET NEWNAME FOR DATAFILE 3 TO ‘/oradata3/cwmlite01.dbf‘; 

  SET NEWNAME FOR DATAFILE 4 TO ‘/oradata4/drsys01‘; 

  SET NEWNAME FOR DATAFILE 5 TO ‘/oradata5/example01.dbf‘; 

  SET NEWNAME FOR DATAFILE 6 TO ‘/oradata6/indx01.dbf‘;

  # Do not set a newname for datafile 7, because it is in the tools tablespace,

  # and you are excluding tools from the duplicate database.

  SET NEWNAME FOR DATAFILE 8 TO ‘/oradata7/users01.dbf‘; 

  DUPLICATE TARGET DATABASE TO dupdb

    SKIP TABLESPACE tools

    LOGFILE

      GROUP 1 (‘/duplogs/redo01a.log‘, 

               ‘/duplogs/redo01b.log‘) SIZE 200K REUSE, 

      GROUP 2 (‘/duplogs/redo02a.log‘, 

               ‘/duplogs/redo02b.log‘) SIZE 200K REUSE;

}

上面的命令还使用过SKIP TABLESPACE子句跳过指定表空间

另外还可以使用CONFIGURE AUXNAME 命令重命名数据文件，复制步骤如下： 

#configurethenewdesiredfilenames 

CONFIGURE AUXNAME FOR DATAFILE 1 TO ‘F:\oracle\oradata\jssdup\system01.dbf‘; 

CONFIGURE AUXNAME FOR DATAFILE 2 TO ‘F:\oracle\oradata\jssdup\undotbs01.dbf‘; 

#...addmoreCONFIGUREAUXNAMEcommandsasneeded 

不过需要注意的是，duplicate执行完之后，推荐清除CONFIGUREAUXNAME。这样就不会对未来的 

类似操作造成影响。 

#clearspecifiedauxiliarynamesforthedatafiles 

CONFIGURE AUXNAME FOR DATAFILE 1 CLEAR; 

CONFIGURE AUXNAME FOR DATAFILE 2 CLEAR; 

如果副本数据库与目标库不在同一台机器上，并且副本数据库的在线日志文件路径与目标库相同，NOFILENAMECHECK 

则运行duplicate命令时必须指定NOFILENAMECHECK参数以避免冲突提示。此处oracle表现的很傻，它不知道你要恢复的路径是在另一台机器上，它只是认为要恢复到的路径怎么跟目标数据库表现的一样呢？会不会是要覆盖目标数据库啊，为了避免这种情形，于是它就报错。所以一旦异机恢复，并且路径相同，那么你必须通过指定NOFILENAMECHECK来避免oracle的自动识别。 这里NOFILENAMECHECK不是必须的

4）如果备份文件保存在磁盘上，分配的通道越多则速度越快，如果备份文件在磁带上，最少指定设备数量个通道。

七，使用备份恢复辅助实例

1）在同一服务器上

先备份数据库

backup database plus archivelog ;

然后恢复

RUN
{
  # The DUPLICATE command uses an automatic sbt channel.
  # Because the target datafiles are spread across multiple directories,

 allocate channel prmy1 type disk;
 allocate channel prmy2 type disk;
 allocate channel prmy3 type disk;
 allocate channel prmy4 type disk;

  ALLOCATE AUXILIARY CHANNEL aux1 DEVICE TYPE DISK;
  ALLOCATE AUXILIARY CHANNEL aux2 DEVICE TYPE DISK;
  ALLOCATE AUXILIARY CHANNEL aux3 DEVICE TYPE DISK;

  # run SET NEWNAME rather than DB_FILE_NAME_CONVERT
  SET NEWNAME FOR DATAFILE 1 TO ‘/dsg/oracle11/PROD1/system01.dbf‘;
  SET NEWNAME FOR DATAFILE 2 TO ‘/dsg/oracle11/PROD1/sysaux01.dbf‘;
  SET NEWNAME FOR DATAFILE 3 TO ‘/dsg/oracle11/PROD1/undotbs01.dbf‘;
  SET NEWNAME FOR DATAFILE 4 TO ‘/dsg/oracle11/PROD1/users01.dbf‘;
  SET NEWNAME FOR TEMPFILE 1 TO ‘/dsg/oracle11/PROD1/temp01.dbf‘;
  # Do not set a newname for datafile 7, because it is in the tools tablespace,
  # and you are excluding tools from the duplicate database.
  DUPLICATE TARGET DATABASE TO PROD1 
    LOGFILE
      GROUP 1 (‘/dsg/oracle11/PROD1/redo01a.log‘,‘/dsg/oracle11/PROD1/redo01b.log‘) SIZE 50M REUSE,
      GROUP 2 (‘/dsg/oracle11/PROD1/redo02a.log‘,‘/dsg/oracle11/PROD1/redo02b.log‘) SIZE 50M REUSE,
      GROUP 3 (‘/dsg/oracle11/PROD1/redo03a.log‘,‘/dsg/oracle11/PROD1/redo03b.log‘) SIZE 50M REUSE;
}

说明：在使用DUPLICATE恢复数据库的时候使用的也是源数据库备份目录
