可能新巡檢某臺Oracle數據庫服務器alert日誌會忽然發現有如下輸出：
Wed Nov 21 05:46:04 2018 Incremental checkpoint up to RBA [0x5d02.5e5b.0], current log tail at RBA [0x5d02.7b8b.0] Wed Nov 21 06:06:05 2018 Incremental checkpoint up to RBA [0x5d02.dfe7.0], current log tail at RBA [0x5d02.10ffa.0] Wed Nov 21 06:26:06 2018 Incremental checkpoint up to RBA [0x5d02.16053.0], current log tail at RBA [0x5d02.1859d.0]
不過、這並不是數據庫錯誤，只是因為log_checkpoints_to_alert參數的值設置的是true了，表示允許把checkpoint的信息寫到alert日誌中。
驗證：
SQL> select name,value from v$parameter where name =‘log_checkpoints_to_alert‘;
