主、备库均为Linux相同的系统版本,数据库版本均为Oracle11gR2
主库:10.1.1.1 备库:10.2.2.2
1、确认主备数据库系统
系统:
[root@LINUXIDC1 ~]# uname -a
Linux LINUXIDC1 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
备库:
[root@LINUXIDC2 ~]# uname -a
Linux LINUXIDC2 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
2、在主库设置:
SQL>ALTER DATABASE FORCE LOGGING;
查看下面参数:
如:SQL> show parameter LOG_ARCHIVE_DEST_1
主库
DB_NAME=bhoms
DB_UNIQUE_NAME=bhoms01 (如果是spfile文件,alter system set db_unique_name='bhoms01' scope=spfile; 统一修改参数后,可以重启数据库)
LOG_ARCHIVE_COnFIG='DG_COnFIG=(bhoms01,bhoms02)' (alter system set log_archive_cOnfig='dg_cOnfig=(bhoms01,bhoms02)';)
LOG_ARCHIVE_DEST_1='location=/u01/app/oracle/flash_recovery_area/BHOMS/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=bhoms01'
(alter system set log_archive_dest_1='location=/u01/app/oracle/flash_recovery_area/BHOMS/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=bhoms01';)
LOG_ARCHIVE_DEST_2='service=bhoms02 async valid_for=(online_logfiles,primary_role) db_unique_name=bhoms02'
(alter system set log_archive_dest_2='service=bhoms02 async valid_for=(online_logfiles,primary_role) db_unique_name=bhoms02';)
LOG_ARCHIVE_DEST_STATE_1=ENABLE (alter system set LOG_ARCHIVE_DEST_STATE_1=ENABLE;)
LOG_ARCHIVE_DEST_STATE_2=ENABLE (alter system set LOG_ARCHIVE_DEST_STATE_2=ENABLE;)
FAL_SERVER=bhoms02 (alter system set fal_server=bhoms02;)
FAL_CLIENT=bhoms01 (alter system set fal_client=bhoms01;)
DB_FILE_NAME_COnVERT='bhoms02','bhoms01' (alter system set DB_FILE_NAME_COnVERT='bhoms02','bhoms01' scope=spfile;)
LOG_FILE_NAME_COnVERT='/u01/app/oracle/oradata/bhoms/','/u01/app/oracle/oradata/bhoms','/u01/app/oracle/flash_recovery_area/BHOMS02/onlinelog','/u01/app/oracle/flash_recovery_area/BHOMS01/onlinelog'
(alter system set log_file_name_cOnvert='/u01/app/oracle/oradata/bhoms/','/u01/app/oracle/oradata/bhoms','/u01/app/oracle/flash_recovery_area/BHOMS02/onlinelog','/u01/app/oracle/flash_recovery_area/BHOMS01/onlinelog' scope=spfile;)
STANDBY_FILE_MANAGEMENT=AUTO (alter system set STANDBY_FILE_MANAGEMENT=AUTO;)
关闭数据库:
SQL> shutdown immediate;
启动:
SQL> startup
查看:
SQL> select * from v$dataguard_config;
DB_UNIQUE_NAME
------------------------------
bhoms01
bhoms02
3、在主库备份
[oraoms@LINUXIDC1 ~]$ rman target/
RMAN> backup database;
把备份的数据文件ftp上传到备库/home/oraoms/backup上
ftp 10.2.2.2
输入用户、密码
cd /home/oraoms/backup
bin
put 文件名
bye
在主库上创建备库的控制文件
SQL> alter database create standby controlfile as '/home/oraoms/bhoms02.ctl';
Database altered.
在主库上创建备份需要的pfile文件
SQL> create pfile='/home/oraoms/initbhoms.ora' from spfile;
File created.
把上面的控制文件、pfile文件、密码文件上传到备库
(密码文件位于:$ORACLE_HOME/dbs/orapwbhoms)
4、在备库上对文件授权
[oraoms@LINUXIDC2 backup]$ pwd
/home/oraoms/backup
[oraoms@LINUXIDC2 backup]$ chmod 777 *
5、假设备库上已经安装好数据库名为bhoms的数据库
关闭数据库,,备份数据文件到其他的目录
SQL>shutdown immediate
配置备库tnsnames.ora($ORACLE_HOME/network/admin/tnsnames.ora)
bhoms01 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.1.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bhoms01)
)
)
bhoms02 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.2.2.2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bhoms02)
)
)
测试:
[oraoms@LINUXIDC2 admin]$ tnsping bhoms01
[oraoms@LINUXIDC2 admin]$ tnsping bhoms02
同时配置主库的tnsnames.ora($ORACLE_HOME/network/admin/tnsnames.ora)
bhoms01 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.1.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bhoms01)
)
)
bhoms02 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.2.2.2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = bhoms02)
)
)
测试:
[oraoms@LINUXIDC1 admin]$ tnsping bhoms01
[oraoms@LINUXIDC1 admin]$ tnsping bhoms02
