安装环境

IP地址与机器名 /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1          localhost.localdomain localhost

::1              localhost6.localdomain6 localhost6

172.16.0.173   oracle173       #primary

172.16.0.174   oracle174            #standby

准备安装环境172.16.0.173  oracle173       #primary把数据库软件与实例，监听安装好。

172.16.0.174   oracle174            #standby 只安装数据库软件

 

1.修改oracle173  #primaryr 的tnsnames.ora文件

[oracle@oracle173 ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/

[oracle@oracle173 admin]$ vi tnsnames.ora

 

orcl02 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle174)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

 

orcl01 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle173)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

 

ORCL =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle173)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

2.修改oracle173  #primaryr 的listener.ora

[oracle@oracle173 admin]$ vi listener.ora

 

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = orcl)

      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)

      (SID_NAME = orcl)

    )

  )

 

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = oracle173)(PORT = 1521))

    )

  )

 

ADR_BASE_LISTENER = /u01/app/oracle

3.拷oracle173  #primary 的listener.ora、tnsnames.ora及密码文件 orapworcl  到oracle174

#standby，并修改listener.ora、tnsnames.ora文件  

[oracle@oracle173admin]$cd /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/

$ scp  listener.ora    oracle174:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/

$ scp  tnsnames.ora  oracle174:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/

[oracle@oracle173 admin]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/dbs/

$ scp orapworcl oracle174:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/

 

[oracle@oracle174 ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/

[oracle@oracle174 admin]$ vi listener.ora

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = orcl)

      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)

      (SID_NAME = orcl)

    )

  )

 

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = oracle174)(PORT = 1521))

    )

  )

 

ADR_BASE_LISTENER = /u01/app/oracle

[oracle@oracle174 admin]$ vi tnsnames.ora

orcl02 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle174)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

 

orcl01 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle173)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

 

ORCL =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = oracle174)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

4.启动监听

[oracle@oracle173 dbs]$ lsnrctl start

[oracle@oracle174 admin]$ lsnrctl start

5.创建oracle目录

#oracle173  #primary

[root@oracle173 ~]# mkdir -p /u02/app/oracle/oradata/orcl/

[root@oracle173 ~]# chown -R oracle:oinstall /u02

[root@oracle173 ~]# chmod -R +x /u02

#oracle174   #standby

[root@oracle174 ~]# mkdir -p /u02/app/oracle/oradata/orcl/

[root@oracle174 ~]# chown -R oracle:oinstall /u02

[root@oracle174 ~]# chmod -R +x /u02

[oracle@oracle174 admin]$ mkdir -p /u01/app/oracle/oradata/orcl/

[oracle@oracle174 admin]$ mkdir -p /u01/app/oracle/flash_recovery_area/orcl/

[oracle@oracle174 admin]$ mkdir -p /u01/app/oracle/admin/orcl/adump/

[oracle@oracle174 admin]$ mkdir -p /u01/app/oracle/admin/orcl/dpdump/

[oracle@oracle174 admin]$ mkdir -p /u01/app/oracle/admin/orcl/pfile/

[oracle@oracle174 admin]$ mkdir -p /u01/app/oracle/admin/orcl/scripts/

6.配置oracle173 #primary数据库的参数

[oracle@oracle173 orcl]$ sqlplus / as sysdba

[oracle@oracle173 ~]$ cd /home/oracle/arch/

[oracle@oracle173 arch]$ scp * oracle174:/home/oracle/arch/

 

12. duplicate primary数据库上主库与备库防火墙要关闭

RMAN> connect auxiliary sys/sys_admin@orcl02

connected to auxiliary database: ORCL (not mounted)

RMAN> duplicate target database for standby nofilenamecheck;

13恢复standby数据库（oracle174）

SQL> recover managed standby database disconnect from session;

System altered.

 

#oracle174

16.通过命令查看是否有归档日志恢复

$ tail -f /u01/app/oracle/diag/rdbms/uqn_orcl02/orcl/trace/alert_orcl.log

17.使用LGWR进程进行primary和standby之间的归档日志传输

#添加standby logfile

standby 添加standby logfile

Database altered.

SQL> alter database add standby logfile group 7 ('/u02/app/oracle/oradata/orcl/stb_redo02.dbf') size 50M reuse;

Database altered.

SQL> alter database add standby logfile group 8 ('/u02/app/oracle/oradata/orcl/stb_redo03.dbf') size 50M reuse;

Database altered.

SQL> alter database add standby logfile group 9 ('/u02/app/oracle/oradata/orcl/stb_redo04.dbf') size 50M reuse;

Database altered.

19.修改primary和standby的初始化参数log_archive_dest_2

#primary

[oracle@oracle173 arch]$ vi /u01/app/oracle/product/11.2.0/dbhome_1/dbs/initorcl.ora

------------------------------------------------------

*.log_archive_dest_2='SERVICE=orcl02 VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=uqn_orcl02 LGWR SYNC REOPEN=10'
