DBA: 拥有全部特权，是系统最高权限，只有DBA才可以创建数据库结构。

RESOURCE:拥有Resource权限的用户只可以创建实体，不可以创建数据库结构。

CONNECT:拥有Connect权限的用户只可以登录Oracle，不可以创建实体，不可以创建数据库结构。

没用过grant insert,select这些权限的，不过你可以试试可以吗

如何打开oracle10g审计功能

个表名为SYS.AUD$，位于数据目录下。在一些操作系统中，你还可以给操作系统自己的事件日志子系统写审计记录。 Oracle 10g增加了第三个选项：在一个操作系统目录中写入文件的功能。这些文件可以为XML格式。

在oracle中开启审计功能

sqlplus "/ as sysdba"

show parameter audit

alter system set audit_sys_operations=TRUE scope=spfile;

alter system set audit_trail=DB scope=spfile;

shutdown immediate;

startup force;

Oracle 11g起audit是自动开启的。我很烦这个审计开启，审计日志半个月10G，烦烦烦。我一把都关闭Oracle的审计功能，提高Oracle的空闲率。

oracle数据库的审计功能

在oracle11g中，数据库的审计功能是默认开启的（这和oracle10g的不一样，10g默认是关闭的），

oracle11gr2的官方文档上写的是错的，当上说default是none，而且是审计到db级别的，这样就会

往aud$表里记录统计信息。

1.如果审计不是必须的，可以关掉审计功能；

sql

show

parameter

audit_trail;

------------------------------------

audit_trail

string

sql

alter

system

set

audit_trail=none

scope=spfile;

sql

shut

immediate;

sqlstartup

2.删除已有的审计信息

可以直接truncate表aud$,

truncate

table

sys.aud$;

3.或者将aud$表移到另外一个表空间下，以减少system表空间的压力和被撑爆的风险。
