資料庫備份日誌報錯：RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process，DB版本為11.2.0.4，根據備策略，每天備份歸檔，並且自動刪除檔，保留一個星期的歸檔，手功執如下命令：

delete noprompt archivelog until time 'sysdate-7'；

依然報錯，資訊如下：

在MOS搜尋發現這是11g中的一個bug，描述的原因是在11g中，RMAN檢視的是v$database中的MIN_REQUIRED_CAPTURE_CHANGE#，而不是DBA_CAPTURE。預設情況下，該值每6小時更新一次。因此，在預設情況下，v$database中的值將比當前值晚6個小時。
給出的解決方法是需要在delete 後面加上force。
手動執行delete noprompt force archivelog until time 'sysdate-7', 成功將歸檔刪除。
