linux中oracle设置自动启动

1、修改Oracle系统配置文件/etc/oratab
添加下面这句，oracle 自带的dbstart和dbshut才能够发挥作用。我的为：
$ORACLE_SID:$ORACLE_HOME:Y
这儿的ORACLE_SID和ORACLE_HOME是oracle用户下的环境变量，如果不使用环境变量，就设置个固定的
orcl:/opt/oracle:Y


2、编写服务脚本
用root身份在/etc/rc.d/init.d目录下创建oracle文件作为启动脚本,内容如下:
#!/bin/sh
# chkconfig: 35 80 10
# description: Oracle auto start-stop script.


#
# Set ORACLE_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORACLE_HOME.
ORACLE_HOME=/installed_software/oracle
ORA_OWNER=oracle
if [ ! -f $ORACLE_HOME/bin/dbstart ]
then
    echo "Oracle startup: cannot start"
    exit
fi
case "$1" in
'start')
# Start the Oracle databases:
echo "Starting Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORACLE_HOME/bin/dbstart" >>/var/log/oracle
echo "Done"


# Start the Listener:
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 - $ORA_OWNER -c "$ORACLE_HOME/bin/lsnrctl start" >>/var/log/oracle
echo "Done."
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
touch /var/lock/subsys/oracle
;;


'stop')
# Stop the Oracle Listener:
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 - $ORA_OWNER -c "$ORACLE_HOME/bin/lsnrctl stop" >>/var/log/oracle
echo "Done."
rm -f /var/lock/subsys/oracle


# Stop the Oracle Database:
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 - $ORA_OWNER -c "$ORACLE_HOME/bin/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


3. 改变文件权限
# chmod 755 /etc/init.d/oracle


4. 添加服务
# chkconfig --level 35 oracle on


5. 需要在关机或重启机器之前停止数据库，做一下操作
#ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc2.d/S99oracle  //单用户启动

#ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc3.d/S99oracle  //多用户命令启动

#ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc5.d/S99oracle  //多用户图形化启动

#ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc0.d/K01oracle  //关机执行关闭

#ln -s /etc/rc.d/init.d/oracle /etc/rc.d/rc6.d/K01oracle  //重启执行关闭


6.修改$ORACLE_HOME/bin/dbstart文件

把ORACLE_HOME_LISTNER= /ade/vikrkuma_new/oracle/bin/tnslsnr

修改为ORACLE_HOME_LISTNER=$ORACLE_HOME

否则dbstart启动会报错

Failed to auto-start Oracle Net Listene using /ade/vikrkuma_new/oracle/bin/tnslsnr


6. 使用方法
# service oracle start        //启动oracle
# service oracle stop        //关闭oracle
# service oracle restart     //重启oracle


注意：测试时候使用oracle账号测试，因为大部分人没给root设置ORACLE_HOME环境变量
