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引數，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使用者許可權
# 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@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
這個指令執行時間較長，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系統配置檔案：/etc/oratab，只有這樣，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，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/102 ORA_OWNER=oracle if [ ! -f $ORA_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 - $ORA_OWNER -c "$ORA_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 - $ORA_OWNER -c "$ORA_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 - $ORA_OWNER -c "$ORA_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 - $ORA_OWNER -c "$ORA_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 ;; esac
3. 改變檔案許可權
# chmod 755 /etc/init.d/oracle
4. 新增服務
# 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
