替你百度了一下,不知道对不对，没验证过~

1.命令ps -ef | grep -i ora_arc*找到所有的归档日志进程

oracle 26934 1 0 2017 ? 05:01:52 ora_arc0_orcl
oracle 26936 1 0 2017 ? 02:11:25 ora_arc1_orcl
oracle 26938 1 0 2017 ? 00:17:55 ora_arc2_orcl
…

2.根据路径中的“thread_1”猜测是“ora_arc1_orcl”这个进程锁了文件
3.命令kill -9 26936结束进程“ora_arc1_orcl”
4.命令delete noprompt archivelog all;，没有再遇到"currently being accessed"这样的问题
提醒：过段时间运行命令ps -ef | grep -i ora_arc*会发现刚才杀掉的进程“ora_arc1_orcl”会自动恢复

不错
