oracle12c存在pdb情况下的dataguard简单搭建

--  Oracle 12c Data Guard




-- 12c DG 特点及搭建注意点
- 特点;
Oracle 12c 的DataGuard 是在CDB级别实现的.但在有pdb的情况下与12c之前的版本有些区别.
在Oracle 12c的架构里，online redo log 和控制文件是保存在CDB中的，PDB中只有自己的数据文件，
所以我们这里加standby redo log，也是在CDB中加。


- 注意点;
备库在 rman restore数据文件时,需要注意创建pdb(还有pdbseed数据库)的目录.




-- 规划
- cat /etc/hosts
192.168.128.228 wh -- primary
192.168.128.229 sh   -- standby 


用主库上的PDB：POC_PDB 做我们的主库。


- 实例名：
DG Role --- DB_UNIQUE_NAME ---  Oracle Net Service Name
Primary poc_shpoc_sh
standby poc_whpoc_wh


- 归档路径;
/u01/fra -- FRA

1. 在备库rman restore database完成后, alert日志报错如下;
ORA-00313: open failed for members of log group 3 of thread 1

在dg同步开启后,主库切换几次日志,备库就会自动创建出 redo,standby redo


restore 完成后,备库目录;
