Oracle通过rman进行克隆,你知道如何做吗？

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 $value
三.?创建实例密钥文件
  • 主库生成密钥文件
orapwd FILE=/u01/app/oracle/dbs/orapwora235 password=li0924 entries=5;
  • 将密钥文件传输到备库
scp /u01/app/oracle/dbs/orapwora235 oracle@192.168.1.221:/u01/app/oracle/dbs
四.?创建参数文件
  • 主库通过spfile生成pfile文件
create pfile from spfile;
  • 复制参数文件到Standby库
scp /u01/app/oracle/dbs/initora235.ora oracle@192.168.1.221:/u01/app/oracle/dbs
  • 将Standby端启动到nomount状态
[oracle@oracle221 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4.0 Production on Thu Aug 9 22:56:49 2018

Copyright (c) 1982, 2013, 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  780824576 bytes
Fixed Size      2257312 bytes
Variable Size    511708768 bytes
Database Buffers   264241152 bytes
Redo Buffers      2617344 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 = 1521)(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

  (DESCRIPTION_LIST =
    (DESCRIPTION =
       (ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.221)(PORT = 1521)(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 = 1521))
      (CONNECT_DATA =
  (SERVICE_NAME = db_primary)
      )
     (HS = OK)
  )
  
tns_standby=
  (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.221)(PORT = 1521))
    (CONNECT_DATA =
    (SERVICE_NAME = db_standby)
    )
 (HS = OK)
  )

　

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
