RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 4121 and starting SCN of 152305555

在11g官方文件error messages中對錯誤描述如下：
RMAN-06054: media recovery requesting unknown archived log for thread string with sequence string and starting SCN of string

Cause: Media recovery is requesting a log whose existence is not recorded in the recovery catalog or target database control file.
Action: If a copy of the log is available, then add it to the recovery catalog and/or control file via a CATALOG command and then retry the RECOVER command. If not, then a point-in-time recovery up to the missing log is the only alternative and database can be opened using ALTER DATABASE OPEN RESETLOGS command.

可見，出先此錯誤的原因是恢復需要的日誌記錄在控制檔案或恢復目錄中找不到。解決方法分兩種情況：
1.如果相關的日誌存在且可用的話，就將此日誌記錄新增到控制檔案或恢復目錄中。
2.如果相關的日誌已經被刪除了或不可用了，那麼就按照錯誤的提示scn將資料庫恢復到此scn，本案例是152305555。也就是說此時資料庫只能進行不完全恢復了.
3.在開啟資料庫時得使用resetlogs開啟。

RMAN>  recover database until scn 152305555;
