昨天晚上4点被电话吵醒，夜班同事说产线无法使用，打开电脑，用Toad直接连数据库OK.查看log,说是无法写archive log.查看硬盘空间，有140G可用。Select * from v$lock,一分钟都没有跑出来，cancel掉。夜班同事又打电话催，干脆重新启动算了，也不找根本原因了。结果下了shutdown immediate命令之后，两分钟仍无反应。在等数据库shutdown的时候，再次检查了一下硬盘，天哪，只剩140M了，刚才没睡醒，看成了140G了，赶快删除掉一些archive log,数据库很快shutdown 了，赶快再startup,乌龙一场。
因为要休长假，将数据库交给其他同事管理，他一周都没清理archive log,我也没去检查，哎，自做自受。今天上班都没精神。以下是log。
