Oracle数据库登录的身证验证

二、Oracle登录认证方式
《Oracle管理与维护.手工创建数据库以及脚本》一文中提到如下一个错误：
[oracle@liwei oracle]$ sqlplus "/ as sysdba"
SQL*Plus: Release 10.2.0.1.0 - Production on Thu May 1 14:51:59 2008
Copyright (c) 1982, 2005, Oracle. All rights reserved.
ERROR:
ORA-01031: insufficient privileges
这个便是登录认证方式的问题了。
Oracle登录认证有两种方式：基于操作系统的登录认证和基于Oracle密码文件的登录认证。
具体方式记录在服务端$ORACLE_HOME/network/admin/sqlnet.ora文件中，不过Windows与
Unix/Linux具体设置是不同的。
(一)<Windows>
sqlnet.ora文件为空时采用Oracle密码文件验证
SQLNET.AUTHENTICATION_SERVICES= (NTS) 基于操作系统验证；
SQLNET.AUTHENTICATION_SERVICES= (NONE) 基于Oracle密码文件验证
SQLNET.AUTHENTICATION_SERVICES= (NONE,NTS) 二者并存，注意是半角，否则不识别
sqlnet.ora示例一：
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.
#SQLNET.AUTHENTICATION_SERVICES = (NTS)
C:\Documents and Settings\Administrator>sqlplus " / as sysdba"
SQL*Plus: Release 9.2.0.1.0 - Production on Mon May 5 17:54:32 2008

使用子查询插入数据：
示例一：insert into employee (empno,ename,sal,deptno)
select empno,ename,sal,deptno from emp
where deptno=20;
示例二：insert /*+APPEND*/ into employee (empno,e ......
