搭建11g data guard(duplicate from active database方式)

原创 Linux操作系统 作者:renjixinchina 时间:2013-08-08 17:42:27 0 删除 编辑

1)   安装备库服务器oracle 软件

2)   配置主库服务器和备库服务器网络

[root@db11g01 ~]# more /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

172.16.94.33 db11g01.oracle.com db11g01

172.16.94.34 db11g02.oracle.com db11g02

 

[root@db11g02 ~]# more /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

172.16.94.34 db11g02.oracle.com db11g02

172.16.94.33 db11g01.oracle.com db11g01

3)   主库Enable Forced Logging

SQL>  ALTER DATABASE FORCE LOGGING;

 

Database altered.

4)   主库设置归档

mkdir -p /u01/app/oracle/archivelog

[oracle@db11g01 ~]$ sqlplus / as sysdba

-rw-r----- 1 oracle oinstall 2939392 Aug  8 06:51 1_156_821520350.dbf

 

5)   设置主库初始化参数

添加如下参数

DB_NAME=orcl

DB_UNIQUE_NAME=orcl

LOG_ARCHIVE_CONFIG='DG_CONFIG=(orcl,stdby)'

LOG_ARCHIVE_DEST_1='LOCATION=/u01/app/oracle/archivelog  VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=orcl'

LOG_ARCHIVE_DEST_2='SERVICE=stdby ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=stdby'

LOG_ARCHIVE_DEST_STATE_1=ENABLE

LOG_ARCHIVE_DEST_STATE_2=ENABLE

REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE

 

 

 

FAL_SERVER=stdby

DB_FILE_NAME_CONVERT='stdby','orcl'

LOG_FILE_NAME_CONVERT='stdby','orcl'

STANDBY_FILE_MANAGEMENT=AUTO

 

6)   配置主库listenertnsname

修改主库listener

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = stdby)

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

      (SID_NAME = stdby)

    )

  )

 

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = db11g02.oracle.com)(PORT = 1521))

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

    )

  )

 

ADR_BASE_LISTENER = /u01/app/oracle

 

注意配置静态注册(主库和备库都设置)

 

修改主库tnsnames

ORCL =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = db11g01.oracle.com)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

stdby =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = db11g02.oracle.com)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = stdby)

    )

  )

7)   创建备库目录

mkdir -p /u01/app/oracle/oradata/stdby

mkdir -p /u01/app/oracle/fast_recovery_area/stdby

mkdir -p /u01/app/oracle/admin/stdby/adump

8)   配置备库listenertnsname

从主库copy过来 把侦听的机器名进行修改即可

启动侦听

9)   创建备库初始化参数

*.audit_file_dest='/u01/app/oracle/admin/stdby/adump'

*.audit_trail='db'

*.compatible='11.2.0.0.0'

*.control_files='/u01/app/oracle/oradata/stdby/control01.ctl','/u01/app/oracle/fast_recovery_area/stdby/control02.ctl'

*.db_block_size=8192

*.db_domain=''

*.db_name='orcl'

*.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'

*.db_recovery_file_dest_size=5218762752

*.diagnostic_dest='/u01/app/oracle'

*.log_checkpoints_to_alert=TRUE

*.memory_target=1698693120

*.open_cursors=300

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.undo_tablespace='UNDOTBS1'

 

DB_UNIQUE_NAME=stdby

LOG_ARCHIVE_CONFIG='DG_CONFIG=(stdby,orcl)'

LOG_ARCHIVE_DEST_1='LOCATION=/u01/app/oracle/archivelog  VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=stdby'

LOG_ARCHIVE_DEST_2='SERVICE=orcl ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcl'

LOG_ARCHIVE_DEST_STATE_1=ENABLE

LOG_ARCHIVE_DEST_STATE_2=ENABLE

REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE

 

 

 

FAL_SERVER=orcl

DB_FILE_NAME_CONVERT='orcl','stdby'

LOG_FILE_NAME_CONVERT='orcl','stdby'

STANDBY_FILE_MANAGEMENT=AUTO

10)        创建备库
