ERROR:
ORA-09925: Unable to create audit trail file
Linux-x86_64 Error: 2: No such file or directory
Additional information: 9925
ORA-01075: you are currently logged on
查看参数文件：
*.audit_file_dest='/u01/app/oracle/admin/PROD/adump'
在服务器上查看没有这个目录，解决方法就是建立这个目录并且赋予读写权限
原因：
| $ORACLE_HOME/rdbms/audit 是不是空间满了? 当前用户对$ORACLE_HOME/rdbms/audit 没有写权限? audit_file_dest的设置是不是改了,不是默认的$ORACLE_HOME/rdbms/audit 路径了? 不管audit_trace设不设, DB对以下三项都是要audit的: 1.conn / as sysdba or / as sysoper 2.db shutdown 3.db startup |
