RMAN> quit
再備份即ok =======================================================================================================================
正确使用rman crosscheck
crosscheck archivelog all 用RMAN的備份中（Veritas等備份軟體由于歸檔日志的異常導緻歸檔日志備份失敗）是經常碰到的，解決方法也是非常解單，就是執行2條RMAN的指令：
1. 進入rman
2. connect target /
3. crosscheck archivelog all; //檢查控制檔案和實際實體檔案的差别。
4. delete expired archivelog all; //同步控制檔案的資訊和實際實體檔案的資訊。
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
這2條指令做什麼事情，原理是什麼。下面說明一下：
在controlfile中記錄着每一個archivelog的相關資訊，當我們在OS下把這些實體檔案delete掉或異常變動後，在controlfile中仍然記錄着這些archivelog的資訊，當我們手工清除archive目錄下的檔案後，這些記錄并沒有被我們從controlfile中清除掉，也就是oracle并不知道這些檔案已經不存在了!這時候我們要做手工的清除。 crosscheck archivelog all；的作用就是檢查控制檔案和實際實體檔案的差别。
delete expired archivelog all;就是同步控制檔案的資訊和實際實體檔案的資訊。 如果單獨執行crosscheck而沒有執行delete那麼備份還是失敗的，原因是那些控制檔案的資訊和實際的資訊還是不同。 crosscheck backupset crosscheck backupset 是檢查備份集和實際的檔案 1 備份集有兩種狀态A(Available,RMAN認為該項存在于備份媒體上)X(Expired，備份存在于控制檔案或恢複目錄中，但是并沒有實體存在于備份媒體上）
2 crosscheck 的目的是檢查RMAN 的目錄以及實體檔案，如果實體檔案不存在于媒體上，将标記為Expired。如果實體檔案存在，将維持Available。如果原先标記為Expired的備份集再次存在于備份媒體上（如恢複了損壞的磁盤驅動器後），crosscheck将把狀态重新從Expired标記回Available。
3 crosscheck 輸出分兩部分。第一部分列出确定存在于備份媒體上的所有備份集片，第二部分列出不存在于備份媒體上的備份集片，并将其标記為Expired。當設定備份儲存政策後，一個備份過期，crosscheck之後标記為丢棄的備份狀态依舊為availabel,要删除丢棄備份delete obsolete itpub一執行個體
我的一個Unix下 oracle資料庫在遷移當中一個歸檔檔案丢失了，rman備份歸檔日志時提示 某個歸檔日志找不到， 請問如何在不停止oracle資料庫情況下 截斷歸檔日志，重新開始新的歸檔!
crosscheck archivelog all
delete archivelog all;
