在CentOS 6.3下安裝完Oracle 10g R2，重開機之后，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
登錄到CentOS，切換到oracle用戶權限
# 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
就可以正常的啟動數據庫了。
另外停止數據庫的指令如下：
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
然后輸入密碼，sys以sysdba身份登入數據庫。
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
這個指令運行時間較長，執行完的畫面如下：
手動啟動Oracle數據庫完畢，下面創建系統自行啟動Oracle的腳本。
四、Oracle啟動&停止腳本
1. 修改Oracle系統配置文件：/etc/oratab，只有這樣，Oracle 自帶的dbstart和dbshut才能夠發揮作用。
# vi /etc/orataborcl:/opt/oracle/102:Y# Entries are of the form:# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
2. 在 /etc/init.d/ 下創建文件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. 改變文件權限
# chmod 755 /etc/init.d/oracle
4. 添加服務
# chkconfig --level 35 oracle on
5. 需要在關機或重啟機器之前停止數據庫，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
