记一次DG搭建过程中ORA-09925: Unable to createaudit trail file 错误

今天做Oracle DG 编写initorcl的时候，修改完以后，sqlplus就不能再登陆，一直报

ERROR:

ORA-09925: Unable to createaudit trail file

Linux Error: 2: No such file ordirectory

Additional information:9925

ORA-01075: you are currentlylogged on

一直找不到原因，后来在网上偶然找到个帖子说了这样一个情况，试了下，果然有效

[oracle@Allen adump]$ ps -ef|grep smon

oracle 2479 1 0 02:52 ? 00:00:00ora_smon_allen

oracle 27854 1 0 08:43 ? 00:00:00 ora_smon_prod
