1.环境
Target DB:
IP:10.131.119.114

HOSTNAME:openstack-node1.example.com

ORACLE_SID:orcl11g


Auxiliary DB:

IP:10.131.119.114
HOSTNAME:openstack-node1.example.com
ORACLE_SID:aux

2.创建Auxiliary DB 参数文件
[oracle@openstack-node1 dbs]$ cat initaux.ora
*.audit_file_dest='/u2/oracle/admin/aux/adump'
*.audit_trail='db'
*.compatible='11.2.0.0.0'
*.control_files='/u2/oracle/oradata/aux/control01.ctl','/u2/oracle/fast_recovery_area/aux/control02.ctl'
*.db_block_size=8192
*.db_domain='us.oracle.com'
*.db_name='aux'
*.db_recovery_file_dest='/u2/oracle/fast_recovery_area'
*.db_recovery_file_dest_size=4227858432
*.diagnostic_dest='/u2/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=auxXDB)'
*.log_archive_dest_1='location=/u2/oracle/arch/aux'
*.open_cursors=300
*.pga_aggregate_target=104857600
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.sga_max_size=272629760
*.sga_target=272629760
*.undo_tablespace='UNDOTBS1'
*.db_file_name_convert=('orcl11g','aux')


3.创建Auxiliary DB需要的目录
[oracle@openstack-node1 ~]$ mkdir -p /u2/oracle/admin/aux/adump
[oracle@openstack-node1 ~]$ mkdir -p /u2/oracle/oradata/aux
[oracle@openstack-node1 ~]$ mkdir -p /u2/oracle/fast_recovery_area/aux
[oracle@openstack-node1 ~]$ mkdir -p /u2/oracle/arch/aux

4.创建Auxiliary DB密码文件
[oracle@openstack-node1 dbs]$ cp orapworcl11g orapwaux


5.配置监听与TNS
监听：
[oracle@openstack-node1 admin]$ cat listener.ora
# listener.ora Network Configuration File: /u2/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = orcl11g)
      (ORACLE_HOME = /u2/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = orcl11g)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = aux)
      (ORACLE_HOME = /u2/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = aux)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.114)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /u2/oracle


TNS：


[oracle@openstack-node1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u2/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORCL11G =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.114)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl11g)
    )
  )

aux =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.114)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = aux)
    )
  )


6.开始复制操作
[oracle@openstack-node1 ~]$ rman target /     ----连接target DB
