载安装9ias的时候碰见这么一个错误：
Installation has detected that a fully qualified hostname has not been specified for this host.Oracle 9i Application Server installation requires  a
default domain name to be specified for each host where it is installed. Please consult your operating system instructions for detials on assigning a default domain name. If you are not using a DNS server,  then the file
c:\WINNT\system32\drivers\etc\hosts must also include a line of the form:

<IP_ADDRESS><FULL_QUALIFIED_HOSTNAME><ALIASES>
After making these changes,please reboot the host and restart the install.


我不太明白为什么还需要域啊，还有后面说那个如果没有域的话
配置那个hosts，我没看明白是怎么个配法，比如我说我的机器名
叫student,我的ip地址是192.168.0.222那该如何配置啊？

在里面随便加上一个域
比如: students.neu.edu.cn

在你的hosts文件中加入以下一行
your IP hostname.domain_name
比如
192.168.0.2 students.neu.edu.cn
