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;
