本人新手 公司要求配置dataguard 我在自己的电脑上用虚拟机先做测试 然后再配置到服务器上去
redhat5+oracle 10.2.0.1
主库：192.168.0.100 SID/db_unique_name/db_name都是：orcl
备库：192.168.0.101 db_name:orcl db_unique_name:orcldg SID:orcldg
主备库都按照网上的文档配置成功了 可以在主库归档以后 在备库能接受到归档日志
现在想要主备库可以自动切换，网上说可以用broker,我不懂就按照网上的文档来配置
有几个问题想问问各位大侠
1 dgmgrl是必须在第三方客户机上启动么 我现在两台电脑 上面都是redhat5+oracle10.2.0.1
还是我只要在主库或者备库里面直接开启一个终端 然后输入dgmgrl就可以开始配置了
2 我是直接在备库里开终端 输入dgmgrl开始配置的 但是在enable configuration的时候就会卡 住不动，退出来show configuration的时候也是卡主不动
我的主库备库都是在mount状态下开始配置的 打开了falshback 也在主备库上配置了alter system set dg_broker_start = true scope=both;
一些配置文件贴出来 如下：
