2.相关知识点
oracle Data Guard，以最低成本实现最高的数据保护。在硬件上没有特殊要求，普通PC机即可实现。
简单的来说，Data Guard，就是自动创建和维护生产数据库（或主数据库）的一个或多个事务一致的副本（备用数据库）。如果主数据库不可用（因为故障、维护或者灾难），那么可以激活一个备用数据库并使之承担主数据库的角色。然而，在配置完成Data Guard后，若需要实现主备数据库间的切换，需要在主数据库及备用数据库上分别输入多个命令，切换步骤稍显麻烦。所以，一般情况下，DBA会将整个切换过程编辑成脚本，以便自动运行，进行状态切换。当然，oracle也提供了工具Data Guard broker，仅在控制端输入一个命令就能方便实现主备数据库间的切换。
在Data Guard broker的基础上，配置并启用Fast-Start Failover，就能自动检测发现主机故障，实现主备切换，故障转移。
Data Guard broker是建立在Data Guard基础上的一个对Data Guard配置，集中管理操作的一个平台。broker的推出是为了简化DG复杂的管理过程，它最大的作用就是集中化的统一管理。
配置Data Guard broker使用到的客户端工具是DGMGRL。它是一个命令行管理工具。
3.实验部分
3.1实验目标
Data Guard broker的配置并完成实验。
3.2前提条件
注意前提条件，Data Guard已经成功配置完成。
1.设置primary和standby启动时参数文件为spfile
2.配置DG_broKER_CONfig_FILEn
DG_broKER_CONfig_FILEn代表2个参数，分别为DG_broKER_CONfig_FILE1，DG_broKER_CONfig_FILE2，它们是Data Guard broker的配置文件名。它们都有默认值（windows下是在ORACLE_HOME/database目录下，linux下是在ORACLE_HOME/dbs目录下），所以一般我们可以不进行特别设置。
3.设置listener
在Data Guard broker环境中，需要在listener.ora静态添加一个service_name为db_unique_name_DGMGRL.db_domain的注册。这个service_name会在DGMGRL重启数据库的时候用到。通过DGMGRL重启数据库时DMON进程会先将数据库关闭，然后DGMGRL用此service_name通过listener连接到数据库，发出启动命令。
4.设置DG_broKER_START为TRUE
这一步是启动Data Guard broker monitor（DMON）进程，需要在2个数据库上面都运行下面的命令
alter system set dg_broker_start=true scope=both;

在配置broker完成后，我们就可以利用broker完成switchover了。在DGMGRL中只需要简单的一个命令。
switchover to standby-database
(standby-database: 此参数是db_unique_name，大小写敏感。如果名称是大写的，需要用引号。表示切换standby-database为主机，原主机转换为备机状态)
oradg11g - 主数据库
oradgphy - 物理备用数据库
DGMGRL>switchover to oradgphy;
立即执行切换,请稍候...
新的主数据库 "oradgphy" 正在打开...
操作要求关闭实例 "oradg11g" (在数据库 "oradg11g" 上)
正在关闭实例 "oradg11g"...
ORACLE 例程已经关闭。
操作要求启动实例 "oradg11g" (在数据库 "oradg11g" 上)
正在启动实例 "oradg11g"...
ORACLE 例程已经启动。
数据库装载完毕。
数据库已经打开。
切换成功,新的主数据库为 "oradgphy"
oradgphy - 主数据库
oradg11g - 物理备用数据库
再切换一次，回到最初状态：
DGMGRL>switchover to oradg11g;
新的主数据库 "oradg11g" 正在打开...
操作要求关闭实例 "oradgphy" (在数据库 "oradgphy" 上)
正在关闭实例 "oradgphy"...
操作要求启动实例 "oradgphy" (在数据库 "oradgphy" 上)
正在启动实例 "oradgphy"...
数据库为 "oradg11g"
