千家信息网最后更新 2025年11月07日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 sysdbaSQL*Plus: Release 11.2.0.4.0 Production on Thu Aug 9 22:56:49 2018Copyright (c) 1982, 2013, Oracle.

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  lottuSQL> 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;
