oracle自启动和关机自关闭，以前也没有好好弄过，只是曾经部署再AIX下使用过，也是利用的别人的现成代码，自己没有好好的理解过：
这次对linux下的实现方式，做一个初步的学习，脚本也同样来自互联网，我通过调试测试通过，通过这个学习也对自启动脚本有进一步的了解：
1、 修改Oracle系统配置文件/etc/oratab
/etc/oratab ：
把AUTO域设置为Y(大写)，只有这样，oracle 自带的dbstart和dbshut才能够发挥作用。
实际上在脚本里面也是利用dbstart和lsnrctl start来完成数据库的启动；
例如我修改的我得如下：
lht:/home/oracle/ora/products/9.2.0:Y
2、 编写服务脚本：
如下
#!/bin/bash
#
#################FUNCTION#############
#
# AutoStart Oracle and listener
# AutoStop Oracle and listener
#
#####################################
#
#
case "$1" in
start)
echo "Starting Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Databasee as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - oracle -c "dbstart" >> /var/log/oracle
echo "Done."
echo "Starting Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - oracle -c "lsnrctl start" >> /var/log/oracle
echo "Done."
echo ""
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
touch /var/lock/subsys/oracle
;;
stop)
echo "Stoping Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - oracle -c "lsnrctl stop" >> /var/log/oracle
echo "Done."
rm -f /var/lock/subsys/oracle
echo "Stoping Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - oracle -c "dbshut" >>/var/log/oracle
echo "Done."
echo ""
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
;;
restart)
$0 stop
$0 start
;;
*)
echo "Usage: oracle {start|stop|restart}"
exit 1
esac
将脚本命名为oracle，保存在/etc/rc.d/init.d下
改变文件属性：chmod 755 oracle
注意：在windows下编辑此文件时有DOS格式字符导致在linux下不能够正常运行，建议用gedit 或用 vi编辑
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。
