oracle系统表空间满

在用sqlplus user/password@truth登录数据库时报如下错误：
ORA-00604: error occurred at recursive SQL level 1
ORA-01653: unable to extend table SYS.AUD$ by 8192 in tablespace SYSTEM
ORA-02002: error while writing to audit trail
ORA-00604: error occurred at recursive SQL level 1
ORA-01653: unable to extend table SYS.AUD$ by 8192 in tablespace SYSTEM

ORA-00604: error occurred at recursive SQL level 1的错误指的是内部的SQL语句执行失败
ORA-01653: unable to extend table SYS.AUD$ by 8192 in tablespace SYSTEM 意思是表空间已满

解决方法：

alter tablespace system add datafile '/home/wanson/oradata/lecake/system02.dbf' size 10M;

SYS>select FILE_NAME,TABLESPACE_NAME,STATUS,AUTOEXTENSIBLE,MAXBYTES,INCREMENT_BY from dba_data_files;

FILE_NAME                                                    TABLESPACE_NAME      STATUS    AUT   MAXBYTES INCREMENT_BY
