Linux Oracle服務啟動&停止腳本與開機自啟動

在CentOS 6.3下安裝完Oracle 10g R2，重開機之後，你會發現Oracle沒有自行啟動，這是正常的，因為在Linux下安裝Oracle的确不會自行啟動，必須要自行設定相關參數，首先先介紹一般而言如何啟動oracle。

一、在Linux下啟動Oracle

登入到CentOS，切換到oracle使用者權限

# su – oracle

接着輸入：

$ sqlplus "/as sysdba"

原本的畫面會變為

SQL>

接着請輸入

SQL> startup

就可以正常的啟動資料庫了。

另外停止資料庫的指令如下：

SQL> shutdown immediate

二、檢查Oracle DB監聽器是否正常

回到終端機模式，輸入：

$ lsnrctl status

檢檢視看監聽器是否有啟動

如果沒有啟動，可以輸入：

$ lsnrctl start

啟動監聽器

SQL> conn sys/密碼 as sysdba

sys以sysdba身份登入資料庫。

三、啟動emctl

另外也可以發現http://localhost.localdomain:1158/em 目前是沒有反應的，這邊要另外啟動，啟動的指令如下：

$ emctl start dbconsole

這個指令運作時間較長，執行完的畫面如下：

手動啟動Oracle資料庫完畢，下面建立系統自行啟動Oracle的腳本。

四、Oracle啟動&停止腳本

1. 修改Oracle系統配置檔案：/etc/oratab，隻有這樣，Oracle 自帶的dbstart和dbshut才能夠發揮作用。

# vi /etc/oratab

orcl:/opt/oracle/102:Y

# Entries are of the form:

# $ORACLE_SID:$ORACLE_HOME:<N|Y>:

2. 在 /etc/init.d/ 下建立檔案oracle，内容如下：

#!/bin/sh

# chkconfig: 35 80 10

# description: Oracle auto start-stop script.

# Set ORA_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 ORA_HOME.

ORA_HOME=/opt/oracle/102

ORA_OWNER=oracle

if [ ! -f $ORA_HOME/bin/dbstart ]

then

echo "Oracle startup: cannot start"

exit

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

su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" >>/var/log/oracle

echo "Done"

# Start the Listener:

echo "Starting Oracle Listeners ... "

date +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracle

su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start" >>/var/log/oracle

echo "Done."

date +" %T %a %D : Finished." >> /var/log/oracle

touch /var/lock/subsys/oracle

;;

'stop')

# Stop the Oracle Listener:

echo "Stoping Oracle Listeners ... "

date +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracle

su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop" >>/var/log/oracle

rm -f /var/lock/subsys/oracle

# Stop the Oracle Database:

echo "Stoping Oracle Databases ... "

date +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracle

su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut" >>/var/log/oracle

echo ""

'restart')

$0 stop

$0 start

esac

3. 改變檔案權限

# chmod 755 /etc/init.d/oracle

4. 添加服務

# chkconfig --level 35 oracle on

5. 需要在關機或重新開機機器之前停止資料庫，做一下操作

# ln -s /etc/init.d/oracle /etc/rc0.d/K01oracle //關機

# ln -s /etc/init.d/oracle /etc/rc6.d/K01oracle //重新開機

6. 使用方法

# service oracle start //啟動oracle

# service oracle stop //關閉oracle

# service oracle restart //重新開機oracle

7. 測試

a. 開機自啟動
