客戶虛擬化平臺斷電，導致oracle其數據庫啓動ORA-01200錯誤
SQL> alter database open;alter database open*ERROR at line 1:ORA-01122: database file 1 failed verification checkORA-01110: data file 1: '/oradata/orcl/system01.dbf'ORA-01200: actual file size of 1122560 is smaller than correct size of 1131520 blocks |
對應的alert日誌如下

報錯比較明顯system01.dbf文件本來大小應該爲1131521個block,但是實際上只有1122561個block,因此無法正常啓動,通過修改數據文件欺騙數據庫
然後對異常的system文件進行處理,把人工構造的部分除掉
SQL> alter database datafile 1 resize 8770M;Database altered. |
rman檢測system文件正常
數據庫恢復完成,數據完美恢復(0丟失,不用邏輯遷移),該庫可以繼續使用,以前有過類似case:
bbed處理ORA-01200故障
ORA-01122 ORA-01200故障處理
ORA-1200/ORA-1207數據庫恢復
