linux下oracle设置开机自启动实现方法

时间:2021-07-21人气:-


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: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
