操作系统:Oracle Linux 5.8 64位

oracle软件:oracle 11.2.0.1

角色主机名 IP地址数据库服务名

primary dg1 192.168.3.70 orcl tong

standby dg2 192.168.3.80 orcl cheng

一.primary主库操作

1.在primary服务器安装oracle软件,并创建数据库.在standby服务器只安装oracle软件,不创建数据库.

2.配置监听

[oracle@dg1 dbs]$ cd /u01/product/11.2.0.1/db_1/network/admin/

[oracle@dg1 admin]$ vim listener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = orcl) --primary库的名字

(ORACLE_HOME = /u01/product/11.2.0.1/db_1)

(SID_NAME = orcl)

)

LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.70)(PORT = 1521)) --prmary库的IP地址

)

ADR_BASE_LISTENER = /u01

[oracle@dg1 admin]$ vim tnsnames.ora

tong =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.70)(PORT = 1521)) --primary库的IP地址

)

(CONNECT_DATA =

(SERVICE_NAME = tong) --服务名必须与上面的服务名相同

)

cheng =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.80)(PORT = 1521)) --standby库的IP地址

)

(CONNECT_DATA =

(SERVICE_NAME = cheng)

)

[oracle@dg1 admin]$ lsnrctl stop

[oracle@dg1 admin]$ lsnrctl start

3.在primary库启用归档和日志强行写入redo文件

[oracle@dg1 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Wed Nov 16 14:38:46 2016

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

4.在primary 库添加standbt日志文件(standby文件和redo文件大小一至,文件个数比redo多一个)

SQL> select group#,type,member,IS_RECOVERY_DEST_FILE from v$logfile;

GROUP# TYPE MEMBER IS_

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

5.利用spfile文件内容生成pfile文件

SQL> create pfile='/tmp/2.txt' from spfile; --创建pfile文件,修改pfile文件的内容

File created.

SQL> shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> exit

6.修改pfile文件的内容

[oracle@dg1 ~]$ vim /tmp/2.txt

*.db_unique_name=tong --数据库节点的唯一名字

*.fal_server='cheng' --standby库的网络服务名

*.fal_client='tong' --primary库的网络服务名

*.standby_file_management=auto

*.log_archive_start=true

*.log_archive_config='dg_config=(tong,cheng)' --两个数据库节点的唯一名字

*.log_archive_dest_1='LOCATION=/u01/oradata/tong/archive valid_for=(all_logfiles,all_roles) db_unique_name=tong' --primary库的网络服务名

*.log_archive_dest_2='service=cheng LGWR SYNC AFFIRM valid_for=(online_logfiles,all_roles) db_unique_name=cheng' --standby库的网络服务名

*.log_archive_dest_state_1='ENABLE'

*.log_archive_dest_state_2='ENABLE'

*.log_file_name_convert='/u01/oradata/tong','/u01/oradata/tong'

*.db_file_name_convert='/u01/oradata/tong','/u01/oradata/tong'

[oracle@dg1 ~]$ mkdir -p /u01/oradata/tong/archive --存放归档文件

[oracle@dg1 dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Wed Nov 9 11:56:26 2016

8.备份数据库(备份文件在闪恢复区)

[oracle@dg1 dbs]$ rman target /

RMAN> backup database plus archivelog;

RMAN> backup current controlfile for standby;

镜像数据库：

rman target sys/oracle@orclpr auxiliary sys/oracle@orclst nocatalog
duplicate target database for standby from active database nofilenamecheck;

9.在standby服务器创建目录

[oracle@dg2 u01]$ cd /u01

[oracle@dg2 u01]$ mkdir flash_recovery_area oradata admin

[oracle@dg2 u01]$ mkdir -p /u01/admin/orcl/adump

[oracle@dg2 u01]$ mkdir -p /u01/admin/orcl/pfile

[oracle@dg2 u01]$ mkdir -p /u01/admin/orcl/dpdump

[oracle@dg2 u01]$ mkdir -p /u01/oradata/orcl

[oracle@dg2 u01]$ mkdir -p /u01/oradata/tong/archive --存放归档文件的目录

10.考贝文件到standby服务器

[oracle@dg1 dbs]$ cd /u01/flash_recovery_area/ --考贝闪回恢复区的备份文件

[oracle@dg1 flash_recovery_area]$ scp * oracle@dg2;/u01/flash_recovery_area/

[oracle@dg1 flash_recovery_area]$ cd /u01/product/11.2.0.1/db_1/dbs/

[oracle@dg1 dbs]$ scp *.ora orapwtong oracle@dg2:/u01/product/11.2.0.1/db_1/dbs/ --考贝pfile,spfile参数文件和密码文件(orapwtong)

[oracle@dg1 dbs]$ cd /u01/product/11.2.0.1/db_1/network/admin/

[oracle@dg1 admin]$ scp listener.ora tnsnames.ora oracle@dg2:/u01/product/11.2.0.1/db_1/network/admin/ --考贝监听文件

[oracle@dg1 admin]$

二.standby从库操作

11.修改监听的地址

[oracle@dg2 ~]$ cd /u01/product/11.2.0.1/db_1/network/admin/

[oracle@dg2 admin]$ vim listener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = cheng)

(ORACLE_HOME = /u01/product/11.2.0.1/db_1)

(SID_NAME = cheng)

)

LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.80)(PORT = 1521))

)

ADR_BASE_LISTENER = /u01

[oracle@dg2 admin]$ vim tnsnames.ora

tong =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.70)(PORT = 1521))

)

(CONNECT_DATA =

)

cheng =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.80)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = cheng)

)

[oracle@dg2 admin]$ cd /u01/product/11.2.0.1/db_1/dbs/

[oracle@dg2 dbs]$ mv inittong.ora initcheng.ora --修改pfile文件名

[oracle@dg2 dbs]$ mv orapwtong orapwcheng --修改密码文件名

[oracle@dg2 dbs]$ lsnrctl stop

[oracle@dg2 dbs]$ lsnrctl start
