在CentOS 6.3下安裝完Oracle 10g R2,重開機以後,你會發現Oracle沒有自行啓動,這是正常的,由於在Linux下安裝Oracle的確不會自行啓動,必需要自行設定相關參數,首先先介紹通常而言如何啓動oracle。web
1、在Linux下啓動Oraclesql
登陸到CentOS,切換到oracle用戶權限數據庫
# su – oracleoracle
接着輸入:dom
$ sqlplus "/as sysdba"測試
本來的畫面會變爲
SQL>ui
接着請輸入
SQL> startupspa
就能夠正常的啓動數據庫了。rest
另外中止數據庫的指令以下:
SQL> shutdown immediatecode
2、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啓動
若是沒有啓動,能夠輸入:
$ lsnrctl start
啓動監聽器
SQL> conn sys@orcl as sysdba
而後輸入密碼,sys以sysdba身份登入數據庫。
3、啓動emctl
另外也能夠發現http://localhost.localdomain:1158/em 目前是沒有反應的,這邊要另外啓動,啓動的指令以下:
$ emctl start dbconsole
這個指令運行時間較長,執行完的畫面以下:
手動啓動Oracle數據庫完畢,下面建立系統自行啓動Oracle的腳本。
4、Oracle啓動&中止腳本
1. 修改Oracle系統配置文件:/etc/oratab,只有這樣,Oracle 自帶的dbstart和dbshut纔可以發揮做用。
# vi /etc/oratab
orcl:/opt/oracle/102:Y
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
2. 在 /etc/init.d/ 下建立文件oracle,內容以下:
#!/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 ]thenecho "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. 須要在關機或重啓機器以前中止數據庫,作一下操做
# ln -s /etc/init.d/oracle /etc/rc0.d/K01oracle //關機
# ln -s /etc/init.d/oracle /etc/rc6.d/K01oracle //重啓
6. 使用方法
# service oracle start //啓動oracle
# service oracle stop //關閉oracle
# service oracle restart //重啓oracle
7. 測試
a. 開機自啓動
