11g dataguard 环境中用rman删除主库的归档，出现?RMAN-08137:
?WARNING: archived log not deleted, needed for standby or upstream capture process
通过下述两个sql检查，发现主库的归档都已经应用到standby库
select max(sequence#) from v$archived_log;
select max(sequence#) from v$archived_log where applied='YES';
尝试用下述命令删除7天前的归档
RMAN>crosscheck archivelog all;
RMAN>delete noprompt archivelog until time 'sysdate-7';
错误如下：?
RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process
检查发现数据库开启了附加日志：
select force_logging,supplemental_log_data_min from v$database;
FORCE_LOGGING SUPPLEMENTAL_LOG_DATA_MIN
------------- -------------------------
YES ? ? ? ? ? YES
附加日志之前同步数据时用到的，现在不用了可以关闭掉附加日志
alter database drop supplemental log data;
Database altered
检查dba_capture发现有记录：
select capture_name, status, captured_scn, applied_scn, capture_type from dba_capture;
利用dbms_capture_adm.drop_capture删除相关记录：
exec dbms_capture_adm.drop_capture(capture_name =>'......');?
PL/SQL procedure successfully completed
删除归档正常
RMAN> delete noprompt archivelog until time 'sysdate-7';
方法二：
最后加上force关键字，手动执行delete noprompt force archivelog until time 'sysdate-14'; 成功将归档删除！
