3、建立服务连接：
系统启动时启动数据库，我们需要以下连结∶
--------------------------------------------------------------------------------
$ ln -s ../init.d/oracle /etc/rc.d/rc2.d/S99oracle
$ ln -s ../init.d/oracle /etc/rc.d/rc3.d/S99oracle
$ ln -s ../init.d/oracle /etc/rc.d/rc5.d/S99oracle #rc4.d unused
--------------------------------------------------------------------------------
要在重新启动时停止数据库，我们需要以下连结∶
--------------------------------------------------------------------------------
$ ln -s ../init.d/oracle /etc/rc.d/rc0.d/K01oracle # 停止
$ ln -s ../init.d/oracle /etc/rc.d/rc6.d/K01oracle # 重新启动
如果启动时候遇到这样的错误：
Can't find init file for Database "lht".
Database "lht" NOT started.
这个错误可以/var/log/oracle中看到
解决办法：缺少init file，需要生成initlht.ora文件；
可以去ls /$oracle_home/dbs核实，会发现缺少initlht.ora；
sqlplus "/as sysdba"
create pfile from spfile;
生成完毕；
接着测试，执行dbstart；
[oracle@oracelserver oracle]$ dbstart

至此，算是完成了。
