oracle自动启动

1、编辑Oracle系统配置文件/etc/oratab，可能没有该文件，直接创建
/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：
orcl:/oracle/product/10g:Y

2、 编写服务脚本：

直接拷贝即可，不需要修改

#!/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，可以先手动运行一下，看是否正常。

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∶

--------------------------------------------------------------------------------c
$ ln -s /etc/init.d/oracle /etc/rc.d/rc3.d/S99oracle  对应启动级别3
 
--------------------------------------------------------------------------------

如果要在重新启动时停止数据库，我们需要以下连结∶

-------------------------------------------------------------------------------

$ ln -s /etc/init.d/oracle /etc/rc.d/rc0.d/K01oracle # 停止
$ ln -s /etc/init.d/oracle /etc/rc.d/rc6.d/K01oracle # 重新启动
