在设置Oracle密码时，我们经常会将密码设置的特别复杂（一般由字母、数字和特殊符号组成），值得注意的是，在有特殊符号时，修改密码或着导入导出数据时会遇到很多不必要的麻烦，本文中将会对此情况进行详细的解释和说明：
注:本文中，将以特殊符号“/”为例。
Linux环境下，使用Oracle数据库10g
修改密码
[oracle@olivenan oracle]$ sqlplus '/as sysdba'

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
