一、安装前提#

1.1 物理DG参数#

HOSTNAME	IP	DB_NAME	DB_UNIQUE_NAME	INSTANCE_NAME	SERVICE_NAME	TNSNAME
dg1	192.168.169.220	prod	uni_dg1	prod	dg1	uni_dg1
dg2	192.168.169.221	prod	uni_dg2	Prod_stdby	dg2	uni_dg2

1.2 文件物理路径#

datafile	controlfile	logfile	archivelog	auditfile
/u01/oradata/prod	/u01/oradata/prod /u01/fast_recovery_area/prod	/u01/oradata/prod	/u01/arch	/u01/admin/prod/adump
/u01/oradata/prod_stdby	/u01/oradata/prod_stdby /u01/fast_recovery_area/prod	/u01/oradata/prod_stdby	/u01/arch	/u01/admin/prod_stdby/adump

二、服务器配置修改#

2.1 配置网络#

主库dg1:

[root@dg1 ~]# vi /etc/hosts
[root@dg1 ~]# scp /etc/hosts dg2:/etc/
The authenticity of host 'dg2 (192.168.169.201)' can't be established.RSA key fingerprint is 26:5c:d2:36:66:2b:e2:b3:12:0d:c4:fb:a6:44:97:7b.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'dg2,192.168.169.201' (RSA) to the list of known hosts.root@dg2's password: 123456

Copy

2.2 修改备库实例名#

备库dg2:

[root@dg2 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.169.200 dg1
192.168.169.201 dg2
[root@dg2 ~]# su - oracle
[oracle@dg2 ~]$ vi .bash_profile 
[oracle@dg2 ~]$ source .bash_profile 
[oracle@dg2 ~]$ env |grep SIDORACLE_SID=prod_stdby

Copy

2.3 建立备库目录#

备库dg2:

[oracle@dg2 ~]$ mkdir -p /u01/oradata/prod_stdby
[oracle@dg2 ~]$ mkdir -p /u01/arch
[oracle@dg2 ~]$ mkdir -p /u01/fast_recovery_area/prod_stdby/
[oracle@dg2 ~]$ mkdir /u01/admin/prod/adump -p

Copy

三、建立物理DG#

3.1 主库强制记录日志#

主库dg1:

[oracle@dg1 ~]$ sqlplus / as sysdba
SQL> select log_mode,force_logging from v$database;
LOG_MODE     FOR
------------   ---
NOARCHIVELOG NO
SQL> alter database force logging;
SQL> select log_mode,force_logging from v$database;
LOG_MODE     FOR
------------   ---
NOARCHIVELOG YES
SQL> shutdown immediate
SQL> startup mount;
SQL> alter database archivelog;
SQL> alter database open;
SQL> select log_mode,force_logging from v$database;
LOG_MODE     FOR
------------   ---
ARCHIVELOG    YES

Copy

3.2 配置主备监听#

[oracle@dg1 ~]$ cd /u01/oracle/network/admin/
[oracle@dg1 admin]$ vi tnsnames.orauni_dg1 =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = dg1)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = uni_dg1)))uni_dg2 =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = dg2)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = uni_dg2) ) )[oracle@dg1 admin]$ scp ./tnsnames.ora dg2:/u01/oracle/network/admin/
The authenticity of host 'dg2 (192.168.169.221)' can't be established.RSA key fingerprint is 26:5c:d2:36:66:2b:e2:b3:12:0d:c4:fb:a6:44:97:7b.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'dg2,192.168.169.221' (RSA) to the list of known hosts.oracle@dg2's 
password: [oracle@dg2 ~]$ cd /u01/oracle/network/admin/
[oracle@dg2 admin]$ cat tnsnames.ora 

Copy

3.3 配置主库信息#

主库dg1:

SQL> exit
