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 Copyright (c) 1982, 2009, Oracle.

Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, Real Application Clusters, OLAP, Data Mining and Real Application Testing options SQL> create pfile from spfile; File created. SQL> exit Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, Real Application Clusters, OLAP, Data Mining and Real Application Testing options 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

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' *.open_cursors=300 *.pga_aggregate_target=3809476608 *.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，

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
PROD1@dbrac1 /home/oracle$ rman target sys/oracle@PROD AUXILIARY sys/oracle@PROD1 Recovery Manager: Release 11.2.0.1.0 - Production on Tue Apr 29 14:26:12 2014 Copyright (c) 1982, 2009, Oracle and/or its affiliates.

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:oracleoradatajssdupsystem01.dbf'; CONFIGURE AUXNAME FOR DATAFILE 2 TO 'F:oracleoradatajssdupundotbs01.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; }

2）在不同的服务器
拷贝源数据库的备份集到和源数据库放置备份集相同的目录下，或者NFS挂载到相同的目录下再执行上面的操作
八，参考
