linux下oracle设置开机自启动实现方法

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
sql>

接着请输入
sql> startup

就可以正常的启动数据库了。

另外停止数据库的指令如下：
sql> shutdown immediate

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
orcl:/opt/oracle/102:Y

# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME::

2. 在 /etc/init.d/ 下创建文件oracle，内容如下：

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
# chmod 755 /etc/init.d/oracle

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

5. 需要在关机或重启机器之前停止数据库，做一下操作
# ln -s /etc/init.d/oracle /etc/rc0.d/K01oracle //关机
# ln -s /etc/init.d/oracle /etc/rc6.d/K01oracle //重启

6. 使用方法
# service oracle start //启动oracle
# service oracle stop //关闭oracle
# service oracle restart //重启oracle

7. 测试

a. 开机自启动

代码如下:
