os: Centos 7.4
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;

规划如下

                    maser             slave
$ORACLE_SID          orcl              orcl

db_name:             orcl              orcl
db_unique_name:     orclp            orcls1

acitive dataguard 要求所有成员的 db_name 必须保持一致，通过 db_unique_name 区分各成员。

下面这个图比较常见且经典.
