Oracle與weblogic自動啟動與停止
最近做開發時，發覺每次重新啟動服務器時oracle數據庫若沒有關閉，則必須先關閉后在重新啟動redhat advance server，oracle才能夠正常運行。感覺這樣麻煩，想到能否使數據庫與web服務器與操作系統一同關閉與啟動。在網上查找了一下相關資料，只找到一篇“Oracle Database HOWTO 自動啟動及停止.htm”但是沒有找到有關weblogic自動啟動與停止的文章。經過摸索，我最初的想法實現了，因此想把它寫出來，與大家交流。
服務器環境：
RedHat Advance Server2.1
Oracle 9.2.2 for linux
Weblogic7.0 for Linux
一、 oracle自動啟動與停止
1、 修改Oracle系統配置文件/etc/oratab
/etc/oratab 格式為： SID:ORACLE_HOME:AUTO
把AUTO域設置為Y(大寫)，只有這樣，oracle 自帶的dbstart和dbshut才能夠發揮作用。我的為：
ora9i:/home/oracle/ora/PRodUCts/9.2.0:Y
2、 編寫服務腳本：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 {startstoprestart}"
exit 1
esac
將腳本命名為oracle，保存在/etc/rc.d/init.d下
改變文件屬性：chmod 755 oracle
注重：在windows下編輯此文件時有DOS格式字符導致在linux下不能夠正常運行，建議用gedit 或用 vi編輯
3、建立服務連接：
系統啟動時啟動數據庫，我們需要以下連結∶
--------------------------------------------------------------------------------
$ 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
--------------------------------------------------------------------------------
要在重新啟動時停止數據庫，我們需要以下連結∶
--------------------------------------------------------------------------------
$ ln -s ../init.d/oracle /etc/rc.d/rc0.d/K01oracle # 停止
$ ln -s ../init.d/oracle /etc/rc.d/rc6.d/K01oracle # 重新啟動
二、weblogic自動啟動與停止
假設weblogic安裝在/home/weblogic/bea下。
1、 編寫服務腳本：如下
#!/bin/bash
#
#################FUNCTION#############
#
# AutoStart Weblogic
# AutoStop Weblogic
#
#####################################
#
# Created by ZhouYS 2003-11-26
# Wellhope Information Technology Co.,Ltd
# PUJIANG Science Park(浦江科學園)
#
shutdownweblogic()
{
cd /
# make temp work dir ,you can create it in /tmp
mkdir -p /home/weblogic/zhouys
#
cd /home/weblogic/zhouys
#find weblogic main process
ps -aux grep /home/weblogic >tmp01
#
awk '{print $2}' tmp01 sort > tmp02
#produce kill-main-process script
echo "kill -9 " `sed -n '1p' tmp02` > tmp03
#
chmod 755 tmp03
# kill weblogic
./tmp03
cd /home/weblogic/
sleep 3
rm -rfv zhouys
}
case "$1" in
start)
echo "Starting Weblogic ... "
echo "-------------------------------------------------" >> /var/log/weblogic
date +" %T %a %D : Starting Weblogic as part of system up." >> /var/log/weblogic
echo "-------------------------------------------------" >> /var/log/weblogic
cd /home/weblogic/bea/user_projects/mydomain/ >> /dev/null
. startWebLogic.sh & >> /var/log/weblogic
echo "Done."
echo ""
echo "-------------------------------------------------" >> /var/log/weblogic
date +" %T %a %D : Finished." >> /var/log/weblogic
echo "-------------------------------------------------" >> /var/log/weblogic
touch /var/lock/subsys/weblogic
;;
stop)
echo "Stopping Weblogic ... "
echo "-------------------------------------------------" >> /var/log/weblogic
date +" %T %a %D : Stopping Weblogic as part of system down." >> /var/log/weblogic
echo "-------------------------------------------------" >> /var/log/weblogic
shutdownweblogic
echo "Done."
echo ""
echo "-------------------------------------------------" >> /var/log/weblogic
date +" %T %a %D : Finished." >> /var/log/weblogic
echo "-------------------------------------------------" >> /var/log/weblogic
;;
restart)
$0 stop
#sleep 2 sec to stop all weblogic-process
sleep 2
$0 start
;;
*)
echo "Usage: $0 {startstoprestart}"
exit 1
esac
將腳本命名為weblogic，保存在/etc/rc.d/init.d下
改變文件屬性：chmod 755 weblogic
注重：在windows下編輯此文件時有DOS格式字符導致在linux下不能夠正常運行，建議用gedit 或用 vi編輯, shutdownweblogic函數中沒有加入錯誤控制，各位可以自己完善。
2、 建立服務連接：
要在重新啟動時停止weblogic，我們需要以下連結∶
[root@js-oracle init.d]# ln -s ../init.d/weblogic /etc/rc.d/rc0.d/K01weblogic
[root@js-oracle init.d]
