rhel6.3_oracle11R2的DG搭建安装

安装环境：rhel6.3 oracle11gR2

主库： ip:192.168.38.38 hostname:pri

备库： ip:192.168.38.138 hostname:sty

主库安装oracle软件，安装数据库， 备库只安装oracle软件，没有安装数据库

在主库开启归档：

在主库拷贝数据，控制，日志文件到备库中

[oracle@pri oradata]$ cd /u01/app/oracle/oradata/

[oracle@pri oradata]$ scp -r orclpri/  oracle@192.168.38.138:/u01/app/oracle/oradata

重新启动主库的数据库

[oracle@pri oradata]$ sqlplus / as sysdba

在主库修改参数文件

SQL> create pfile from spfile;

File created.

以下是添加的参数

[oracle@pri dbs]$ vi initorclpri.ora

*.db_unique_name=orclpri
*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclpriXDB)'
*.fal_client='orclpri'
*.fal_server='orclsty'
*.local_listener='LISTENER_orclpri'

*.log_archive_dest_state_1='ENABLE'
*.log_archive_dest_state_2='ENABLE'
*.log_archive_format='%t_%s_%r.arc'

在主库 用上面修改pfile再创建spfile，并重启数据库

创建口令文件

[oracle@pri dbs]$ orapwd file=orapworclpri  password=sys force=y ignorecase=y

拷贝主库的参数和口令文件到备库中

[oracle@pri dbs]$ scp -r orapworclpri  initorclpri.ora  192.168.38.138:/u01/app/oracle/product/11.2.0/dbhome_1/dbs

oracle@192.168.38.138's password:

initorclpri.ora       100% 1359     1.3KB/s  00:00

备库中修改相应的pfile参数文件

[oracle@sty dbs]$ cat initorclpri.ora

这个需要在备库建立相应路径
*.audit_file_dest='/u01/app/oracle/admin/orclpri/adump'

修改控制文件
*.control_files='/u01/app/oracle/oradata/orclpri/standby.ctl'

以下是添加的参数
*.db_unique_name=orclsty
*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclpriXDB)'
*.fal_client='orclpri'
*.fal_server='orclsty'
*.db_file_name_convert='/u01/app/oracle/oradata','/u01/app/oracle/oradata'
*.log_file_name_convert='/u01/app/oracle/oradata','/u01/app/oracle/oradata'

Mount数据库

SQL> alter database mount standby database;

Database altered.

应用redo

SQL> alter database recover managed standby database disconnect from session;

Database altered.

查看数据库角色

SQL> select database_role from v$database;

DATABASE_ROLE
----------------
PHYSICAL STANDBY

查看归档日志scn

SQL> select max(sequence#) from v$archived_log;

MAX(SEQUENCE#)
--------------
19

在主库测试

SQL> alter system switch logfile;

System altered.

SQL> select max(sequence#) from v$archived_log;

备库查看，和主库一直，无问题

SQL> select max(sequence#) from v$archived_log;

MAX(SEQUENCE#)
--------------

附：

取消redo应用，但还是会接受redo的

SQL> alter database recover managed standby database cancel;

Database altered.

以只读模式打开数据库

SQL> alter database open read only;
