redhat 6.4 oracle 11g dataguard 搭建（一）

概述：了解oracle先从安装开始，在日常工作中很大一部分也将会是从安装开始；在oracle中的高可用中有RAC（能够做到实例级别的高可用），而dataguard能够做到操作系统、硬件层面的高可用；当然oracle goldengate也是可以实现并还支持异构跨数据库厂商等优势；本次我们将测试dataguard的安装，dataguard的安装有很多种方法，本人列举三种方法：1、使用冷备搭建；2、使用传统的rman搭建，3、使用rman中的duplicate 复制进行；本文使用冷备搭建，后续测试使用2、3的方法进行；
实验简单步骤：
1、主库安装oracle数据库软件并且dbca监控
2、备库安装oracle数据库软件
3、主库归档模式开启
4、主库修改dataguard 数据库参数
5、主备库监听配置
6、主库关库开始备份数据库文件
7、主库mount状态生产standby control file
8、将备份文件、standby control file、参数文件、密码文件拷贝至备库
9、主库open，备库mount开始应用日志
10、查看dataguard状态，测试dataguard是否搭建成功
实验：

总结：使用冷备份搭建DG完成，各位自行测试吧。明后天会出其他两种方法搭建方法。谢谢

2、备库安装oracle数据库软件
3、主库归档模式开启
4、主库修改dataguard 数据库参数
5、主备库监听配置
6、主库关库开始备份数据库文件
7、主库mount状态生产standby control file
8、将备份文件、standby control file、参数文件、密码文件拷贝至备库

将stand.ctl 拷贝至对用的文件夹中
[oracle@jakki ~]$ cp stand.ctl /u01/app/oracle/oradata/JAKKI1/control01.ctl
[oracle@jakki ~]$ cp stand.ctl /u01/app/oracle/fast_recovery_area/JAKKI1/control02.ctl
