在CentOS 6.3下安装完Oracle 10g R2，重开机之后，你会发现Oracle没有自行启动，这是正常的，因为在Linux下安装Oracle的确不会自行启动，必须要自行设定相关参数，首先先介绍一般而言如何启动oracle。 一、在Linux下启动Oracle 登录到CentOS，切换到oracle用户权限 # su – oracle 接着输入： $ sqlplus "/as sysdba" 原本的画面会变为 接着请输入 就可以正常的启动数据库了。 另外停止数据库的指令如下： 二、检查Oracle DB监听器是否正常 回到终端机模式，输入： $ lsnrctl status 检查看看监听器是否有启动 如果没有启动，可以输入： $ lsnrctl start 启动监听器 SQL> conn sys@orcl as sysdba 然后输入密码，sys以sysdba身份登入数据库。 三、启动emctl 另外也可以发现http://localhost.localdomain:1158/em 目前是没有反应的，这边要另外启动，启动的指令如下： $ emctl start dbconsole 这个指令运行时间较长，执行完的画面如下： 手动启动Oracle数据库完毕，下面创建系统自行启动Oracle的脚本。 四、Oracle启动&停止脚本 1. 修改Oracle系统配置文件：/etc/oratab，只有这样，Oracle 自带的dbstart和dbshut才能够发挥作用。 # vi /etc/oratab # Entries are of the form: 2. 在 /etc/init.d/ 下创建文件oracle，内容如下： 复制代码 代码如下: #!/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 $0 start esac 3. 改变文件权限 4. 添加服务 5. 需要在关机或重启机器之前停止数据库，做一下操作 6. 使用方法 7. 测试 a. 开机自启动 复制代码 代码如下: Last login: Mon Nov 26 19:57:06 2012 from 10.0.0.145 [root@ORS ~]# su - oracle [oracle@ORS ~]$ sqlplus "/as sysdba" SQL*Plus: Release 10.2.0.1.0 - Production on Mon Nov 26 20:07:33 2012 Copyright (c) 1982, 2005, Oracle.
