Oracle 最简单的随系统自动启动

俗话说用户是上帝，他们有时候提出一个问题非常的简单，就只需要一句话，一分钟就完事了，但是拿到我们DBA来说，可能至少得半个小时甚至半个月才能满足他的一句话，有没有更好更快的办法呢，我告诉大家这是有的；

我就拿一个例子来说，用户通常都会为了维护简单，需要数据库自动随系统启动，一句非常简单的话，但是拿给DBA来说至少得多花半个小时的时间来配置实现这个功能。那么今天你看完这篇文档之后，可以在他的话还没有说完就可以完成自启动的配置，非常简单。

一、配置自动

1、添加启动项
[[email protected] ~]# cat >> /etc/rc.d/rc.local <<EOF

su - oracle -c "lsnrctl start"
su - oracle -c "sqlplus sys/oracle as sysdba @/home/oracle/.script/.startup"
su - oracle -c "emctl start dbconsole"
EOF

2、创建并编辑启动文件
[[email protected] ~]#su - oracle
[[email protected] ~]#mkdir -p /home/oracle/.script/

[[email protected] ~]# cat > /home/oracle/.script/.startup <<EOF
startup;
alter system register;
exit 0
EOF

二、重启验证:

三、确定数据库和EM以及监听是否都已经起来

###监听状态
[[email protected] ~]$ lsnrctl status

至此我们已经确定，这样也可以将数据库配置为自动启动，且比Oralce推荐的老方法更为简单，老方法见如下链接：
