此為11g的bug,需要在delete后加上force關(guān)鍵字,metalink上有記載
RMAN-08137 When deleting archivelogs even when Streams CAPTURE does not require them [ID 1079953.1]

Symptoms
Applies To:?11gR1-11gR2
RMAN is unable to delete archive logs from database even though they are not needed by CAPTURE process anymore.
Changes
?
Cause
In 11g, RMAN looks at MIN_REQUIRED_CAPTURE_CHANGE# in v$database and not at DBA_CAPTURE. By default this value is updated every 6 hours. So by default the value in v$database will be six hours behind the current value.
Solution
Since changing frequency of update to MIN_REQUIRED_CAPTURE_CHANGE# in v$database can not be controlled, following workaround can be used:
Archive log which are not needed by capture process can be deleted using:
delete noprompt force archivelog all completed before 'sysdate-10/1440';
PS:我們的環(huán)境是12C DG,該BUG在11g中有明確標(biāo)識(shí),12C就此MARK一下;
