Linux Oracle服務啟動&停止指令碼與開機自啟動，linuxoracle服務

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的確不會自行啟動，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

接著輸入：

$ sqlplus "/as sysdba"

原本的畫面會變為
SQL>

接著請輸入
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

檢查看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@orcl as sysdba

然後輸入密碼，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

這個指令已耗用時間較長，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的指令碼。

四、Oracle啟動&停止指令碼

1. 修改Oracle系統設定檔：/etc/oratab，只有這樣，Oracle 內建的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，內容如下：

#!/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/102ORA_OWNER=oracleif [ ! -f $ORA_HOME/bin/dbstart ]then    echo "Oracle startup: cannot start"    exitficase "$1" in'start')# Start the Oracle databases:echo "Starting Oracle Databases ... "echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oraclesu - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" >>/var/log/oracleecho "Done"# Start the Listener:echo "Starting Oracle Listeners ... "echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oraclesu - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start" >>/var/log/oracleecho "Done."echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Finished." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oracletouch /var/lock/subsys/oracle;;'stop')# Stop the Oracle Listener:echo "Stoping Oracle Listeners ... "echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oraclesu - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop" >>/var/log/oracleecho "Done."rm -f /var/lock/subsys/oracle# Stop the Oracle Database:echo "Stoping Oracle Databases ... "echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oraclesu - $ORA_OWNER -c "$ORA_HOME/bin/dbshut" >>/var/log/oracleecho "Done."echo ""echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Finished." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oracle;;'restart')$0 stop$0 start;;esac

3. 改變檔案許可權
# chmod 755 /etc/init.d/oracle

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

5. 需要在關機或重啟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   //重啟 

6. 使用方法
# service oracle start        //啟動oracle
# service oracle stop        //關閉oracle
# service oracle restart     //重啟oracle

7. 測試

a. 開機自啟動
