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
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
[root@db01 ~]# cat >> /etc/rc.d/rc.local
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 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
