linux下oracle设置开机自启动实现方法

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：

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

# 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

复制代码代码如下:
