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$parameter where name in ( ' audit_file_dest ' , ' background
一. 安装规划
二. 备库创建相应的dump文件夹
# 在主库查询对应的dump目录
select name, value
from v$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

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
LISTENER =
(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)
)
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
