Oracle 最简单的随系统自动启动
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 [root@db01 ~]# 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 [root@db01 ~]#su - oracle [root@db01 ~]#mkdir -p /home/oracle/.script/ [root@db01 ~]# 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 [oracle@db01 ~]$ lsnrctl status LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 03-OCT-2014 07:26:22 Copyright (c) 1991, 2011, Oracle. All rights reserved.

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：
