database：12.2.0.1 + dbf
本次是以 oracle database 12.2.0.1 + dbf 的形式部署的，后面会记录 rac + asm 的形式。
任何时候都要说下三种模式：
最大保护：maximize protection
最高性能：maximize performance
最高可用：maximize availability
alter database set standby to maximize protection;
alter database set standby to maximize performance;
atler database set standby to maximize availability;
oradb-node1 192.168.56.101 master
adb-node1 192.168.56.101 master
安装好了12.2.0.1 的软件，并创建了数据库
dataguard 所有节点的 db_name 是相同的，通过db_unique_name来区分彼此。
