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，欧博普通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，欧博娱乐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，欧博allbetoracle 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)
