---其實只要做完crosscheck archivelog all; 就可以備份了，並不需要 delete expired archivelog all

。

當刪除了某個歸檔(1_3_770566677)後 用RMAN>list archivelog all ; 檢視的時候會有：

RMAN>  list archivelog all;

using target database control file instead of recovery catalog

List of Archived Log Copies
Key     Thrd Seq     S      Low Time    Name
-------     ---- -------  -           ---------        ----
132     1    3         A          22-DEC-11 /data/oracle/flash_recovery_area/LXC/archivelog/1_3_770566677.dbf
133     1    4         A          22-DEC-11 /data/oracle/flash_recovery_area/LXC/archivelog/1_4_770566677.dbf
可以看到1_138_764162411.dbf 狀態是A

但是這個檔案已經不在硬碟上了，

做完crosscheck archivelog all;

再 list archivelog all;看：

Key     Thrd Seq     S      Low Time    Name
-------     ---- -------  -           ---------        ----
132     1    3         X          22-DEC-11 /data/oracle/flash_recovery_area/LXC/archivelog/1_3_770566677.dbf
133     1    4         A          22-DEC-11 /data/oracle/flash_recovery_area/LXC/archivelog/1_4_770566677.dbf

狀態變成X了。這個時候在用 backup archivelog all 就不會報錯了。但是在 list archivelog all;裡面還有這個記錄

用delete expired archivelog all; 可以刪掉無效的記錄。
