安裝過程中遇到的問題:設定成高可用性模式後,主庫PROTECTION_LEVEL始終顯示為RESYNCHRONIZATION

 

standbyalert.log檔案,其中有如下錯誤提示:

FAL[client]: Failed to request gap sequence

GAP - thread 1 sequence 43-60

歸檔缺失,透過rman命令“restore archivelog sequence between 43 and 60;”恢復後,主備庫同步正常,再查主庫狀態:

SQL> select protection_mode,protection_level from v$database;

PROTECTION_MODE      PROTECTION_LEVEL

-------------------- --------------------
