Oracle用户密码含有特殊字符应当如何处理

通常我们在设置Oracle密码时会将密码设置的比较复杂，一般有字母数字特殊符号组成
但是在有特殊符号时，修改密码或着导入导出数据时会遇到麻烦，下文便是对该情况下的解释说明：
本文以特殊符号“/”作为例子
一、Linux环境，数据库为Oracle10g
1、修改密码

[oracle@olivenan oracle]$ sqlplus '/as sysdba'

SQL> alter user test identified by aa/aa;

alter user test identified by aa/aa

                                  *

此处应该使用""

SQL> alter user test identified by "aa/aa";

此处应该进行转义使用 " "处理密码，使用 ' '处理用户名和密码

[oracle@olivenan oracle]$ exp 'test/"aa/aa"' file=test.dmp buffer=65536

二、Windows Xp下，数据库为Oracle9i

C:\Documents and Settings\w>sqlplus /nolog
