#auxiliary端配置：
1. 复制密码文件到auxiliary端：
[oracle@rac01 ~]$ cd $ORACLE_HOME/dbs [oracle@rac01 dbs]$ ls hc_DBUA0.dat hc_orcl1.dat init.ora initorcl1.ora initorcl1.ora.bak.rac01 orapworcl1 snapcf_orcl1.f [oracle@rac01 dbs]$ scp orapworcl1 192.168.88.113:$ORACLE_HOME/dbs/orapwvm #复制节点的密码文件到auxiliary端，更改名为orapwvm
2.配置静态监听
[oracle@class113 trace]$ cd /opt/oracle/product/11.2/db_1/network/admin/ [oracle@class113 admin]$ ls listener.ora samples shrept.lst tnsnames.ora [oracle@class113 admin]$ more listener.ora # listener.ora Network Configuration File: /opt/oracle/product/11.2/db_1/network/admin/listener.ora # Generated by Oracle configuration tools. SID_LIST_LISTENER= #此处可以从samples里面复制样板来进行修改 (SID_LIST= (SID_DESC= (GLOBAL_DBNAME = vm) (ORACLE_HOME = /opt/oracle/product/11.2/db_1) (SID_NAME = vm) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.88.113)(PORT = 1521)) ) ) ADR_BASE_LISTENER = /opt/oracle [oracle@class113 admin]$
3. 根据target生成的参数文件进行修改如下：
[oracle@class113 dbs]$ cd $ORACLE_HOME/dbs
[oracle@class113 dbs]$ more initvm.ora
*.audit_file_dest='/opt/oracle/admin/vm/adump' #
*.audit_trail='db'

*.db_unique_name='vm'
*.db_file_name_convert='+DATA/orcl/datafile','/opt/oracle/oradata','+DATA/orcl/tempfile','/opt/oracle/oradata'
*.log_file_name_convert='+FRA/orcl/onlinelog','/opt/oracle/oradata'
*.db_block_size=8192
*.db_create_file_dest='/opt/oracle/oradata'
*.db_name='orcl'
*.db_recovery_file_dest='/opt/oracle/flash_recovery_area'
*.db_recovery_file_dest_size=9009600000

*.log_archive_config='DG_CONFIG=(vm,orcl)'
*.log_archive_dest_1='LOCATION=/opt/oracle/flash_recovery_area/arch'
*.log_archive_dest_2='SERVICE=TNS_ORCL LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcl'
*.log_archive_dest_state_2='enable'
*.log_archive_format='%t_%s_%r.arc'
*.log_archive_max_processes=8
#*.memory_target=15672864
*.open_cursors=300
*.processes=150
*.remote_login_passwordfile='exclusive'
*.standby_file_management='AUTO'
[oracle@class113 dbs]$
4. 创建数据库所需要的目录
mkdir -p /opt/oracle/admin/vm/adump
mkdir -p /opt/oracle/oradata
mkdir -p /opt/oracle/flash_recovery_area/arch
mkdir -p /opt/oracle/diag
5.启动监听;启动数据库到nomount状态
lsnrctl status
exit
startup nomount
exit
6.复制target数据到物理备库
[oracle@class113 ~]$ rman target sys/oracle@ORCL1 auxiliary sys/oracle@TNS_VM #从RAC01节点复制数据库到auxiliary端
