第三种情况：
参数SQLNET.AUTHENTICATION_SERVICES 设置为 NONE 或NTS ----------------屏蔽操作系统认证都启用口令认证

第四种情况：
当数据库屏蔽了操作系统认证，启用口令认证方式的话，需要检查remote_login_passwordfile参数，如果该参数设置为NONE,该值表示不使用口令文件，因此，此时数据库将不能登录
解决办法：启动操作系统认证，登录数据库后将remote_login_passwordfile参数修改EXCLUSIVE，然后再屏蔽操作系统认证，启用口令认证。
> remote_login_passwordfile参数可以设置为3个值 none、exclusive、shared
