delete force noprompt archivelog until time 'sysdate - _GLOBAL_ORACLE_STANDBY_ARCHIVELOG_RETENSION_DAYS_';

list archivelog all;
list expired archivelog all;

其中 _GLOBAL_ORACLE_STANDBY_ARCHIVELOG_RETENSION_DAYS_ 为 standby 节点需要保留归档日志的天数.
比如:

delete force noprompt archivelog until time 'sysdate - 3';
