问题：

SQL> conn / as sysdba
ERROR:
ORA-09817: Write to audit file failed.
Linux-x86_64 Error: 28: No space left on device
Additional information: 12
ORA-01075: you are currently logged on
分析原因：（经百度查询造成的原因是audit所在的文件系统满了，没有多余的空间）

查看报错日志：cd /u01/app/oracle/diag/rdbms/ora11gr2/ORA11GR2/trace   tail -100f alert_ORA11GR2

Non critical error ORA-48113 caught while writing to trace file "/u01/app/oracle/diag/rdbms/ora11gr2/ORA11GR2/trace/ORA11GR2_mmon_21952.trc"

Error message:
