本文介绍了一种在Linux系统中实现Oracle数据库自动启动和关闭的方法。通过修改配置文件/etc/oratab并设置正确的SID和状态标记，结合创建自定义的服务脚本和相应的系统启动链接，实现了系统启动时自动启动Oracle数据库及监听器，并能在系统关闭时自动停止。

今天晚上学习了如何在启动Linux系统时自动启动oracle数据库,之前也练习了出了点问题,今天继续练习了下,成功了.

练习步骤如下:

Linux下 Oracle自动启动与停止

1、修改Oracle系统配置文件/etc/oratab
/etc/oratab 格式为： SID:ORACLE_HOME:AUTO
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。我的为：
ora9i:/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
