新手学堂 Linux下Oracle的自动启动及停止

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dbstar

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
