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:<n|y>:

2. 在 /etc/init.d/ 下创建文件oracle,内容如下:

#!/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
