-- Oracle 12c Data Guard
-- 12c DG 特點及搭建注意點
- 特點;
Oracle 12c 的DataGuard 是在CDB級別實現的.但在有pdb的情況下與12c之前的版本有些區別.
在Oracle 12c的架構裏，online redo log 和控制文件是保存在CDB中的，PDB中只有自己的數據文件，
所以我們這裏加standby redo log，也是在CDB中加。
- 注意點;
備庫在 rman restore數據文件時,需要注意創建pdb(還有pdbseed數據庫)的目錄.
-- 規劃
- cat /etc/hosts
192.168.128.228 wh -- primary
192.168.128.229 sh -- standby
用主庫上的PDB：POC_PDB 做我們的主庫。
- 實例名：
DG Role --- DB_UNIQUE_NAME --- Oracle Net Service Name
Primary poc_sh

standby poc_wh

1. 在備庫rman restore database完成後, alert日誌報錯如下;
ORA-00313: open failed for members of log group 3 of thread 1
ORA-00312: online log 3 thread 1: '/u01/oradata/poc/redo03.log'
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3
Errors in file /u01/app/oracle/diag/rdbms/poc_sh/poc/trace/poc_lgwr_11161.trc:
在dg同步開啓後,主庫切換幾次日誌,備庫就會自動創建出 redo,standby redo
restore 完成後,備庫目錄;

在備庫開啓恢復後,會開始 clear redo, 注意alert日誌中的 "Clearing online redo logfile 3 complete".
