一. 安装规划

IP	ROLE
192.168.1.235	克隆对象
192.168.1.221	克隆库

二. 备库创建相应的dump文件夹

# 在主库查询对应的dump目录

select name, value

  from v$parameter

 where name in ('audit_file_dest',

                'background_dump_dest',

                'control_files',

                'core_dump_dest',

                'user_dump_dest',

                'db_recovery_file_dest'

                               )

 ORDER BY name ASC;

# 备库用oracle用户执行创建目录

mkdir -p $value

三. 创建实例密钥文件

主库生成密钥文件

orapwd FILE=/u01/app/oracle/dbs/orapwora235 password=li0924 entries=;

将密钥文件传输到备库

scp /u01/app/oracle/dbs/orapwora235 oracle@192.168.1.221:/u01/app/oracle/dbs

四. 创建参数文件

主库通过spfile生成pfile文件

create pfile from spfile;

复制参数文件到Standby库

scp /u01/app/oracle/dbs/initora235.ora oracle@192.168.1.221:/u01/app/oracle/dbs

将Standby端启动到nomount状态

[oracle@oracle221 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4. Production on Thu Aug  :: 

Copyright (c) , , Oracle.  All rights reserved.

Connected to an idle instance.

SQL> startup nomount pfile='/u01/app/oracle/dbs/initora235.ora';

ORACLE instance started.

Total System Global Area   bytes

Fixed Size       bytes

Variable Size     bytes

Database Buffers    bytes

Redo Buffers       bytes

五. 配置主备库的监听文件和网络文件

　　设置Primary库和Standby库的service_name

SQL> show parameter service_name;

NAME         TYPE  VALUE

------------------------------------ ----------- ---------------

service_names        string  lottu

SQL> alter system set service_names='db_primary' scope=both;

System altered.

SQL> show parameter service_name;

NAME         TYPE  VALUE

------------------------------------ ----------- ----------------

service_names        string  db_primary

　　备库的service_name设置为db_standby；需要到参数文件修改。

*.service_names='db_standby'

Primary库配置listener.ora

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

       (ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.235)(PORT = )(IP = FIRST)))

       (ADDRESS_LIST =

         (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))

       )

     )

  )

SID_LIST_LISTENER =

  (SID_LIST =

   (SID_DESC =

     (SID_NAME = ora235)

     (GLOBAL_DBNAME = db_primary)

     (ORACLE_HOME =/u01/app/oracle)

   )

  )

Standby库配置listener.ora

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

       (ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.221)(PORT = )(IP = FIRST)))

       (ADDRESS_LIST =

         (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))

       )

     )

  )

SID_LIST_LISTENER =

  (SID_LIST =

   (SID_DESC =

     (SID_NAME = ora235)

     (GLOBAL_DBNAME = db_standby)

     (ORACLE_HOME =/u01/app/oracle)

   )

  )

Primary库和Standby库设置tnsname.ora

tns_primary=

  (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.235)(PORT = ))

      (CONNECT_DATA =

  (SERVICE_NAME = db_primary)

      )

     (HS = OK)

  )

tns_standby=

  (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.221)(PORT = ))

    (CONNECT_DATA =

    (SERVICE_NAME = db_standby)

    )

 (HS = OK)

  )

　　重启监听lsnrctl restart

六. 克隆Oracle

　　在Standby库执行：DUPLICATE TARGET DATABASE TO ORA235 FROM ACTIVE DATABASE SPFILE NOFILENAMECHECK;

[oracle@oracle221 ~]$ rlwrap  rman target sys/li0924@tns_primary auxiliary sys/li0924@tns_standby
