RMAN> delete noprompt force archivelog all completed before 'sysdate-2';
---说明---
此为11g的bug，需要在delete后加上force关键字，metalink上有记载 RMAN-08137 When deleting archivelogs even when Streams CAPTURE does not require them [ID 1079953.1]
In this Document Symptoms Changes Cause Solution References
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：我们的环境是12C DG，该BUG在11g中有明确标识，12C就此MARK一下；
