oracle 修改设置密码复杂度渐增方法:
1、修改为常见密码(无特殊字符)

SQL> alter user chf identified by xifenfei;

User altered.

2、修改含一般特殊字符(如:$, %等)
SQL>
SQL> alter user chf identified by “xi%,fenfei”;

User altered.

SQL> conn chf/xi%,fenfei
Connected.

3、修改含”的特殊字符
3.1)修改制定用户密码(sys用户操作)
SQL> password chf
Changing password for chf
New password:
Retype new password:
Password changed
SQL> conn chf/aa”"bb
Connected.

3.2)修改当前用户密码(需要有修改密码权限)
SQL> password
Changing password for CHF
Old password:
New password:
Retype new password:
Password changed
SQL>
注:因为一般特殊字符可以使用双引号处理,但是如果密码中含有双引号,就不能用双引号处理,可以直接使用password修改密码

    在shell中无法使用含$的密码使用sqlplus直接登录,而使用sqlplus /nolog connect p/w方式可以登录
    原因是由于$在shell中是定义变量的,因为在sqlplus中直接登录含$的,就无法正常使用,需要转义,或者使用间接登录方式

    具体可以参考sqlplus 直接登录含有$的密码的oracle用户
