Oracle最簡單的隨系統自動啟動

Oracle 最簡單的隨系統自動啟動

俗話說用戶是上帝，他們有時候提出一個問題非常的簡單，就只需要一句話，一分鐘就完事了，但是拿到我們DBA來說，可能至少得半個小時甚至半個月才能滿足他的一句話，有沒有更好更快的辦法呢，我告訴大家這是有的；
我就拿一個例子來說，用戶通常都會為了維護簡單，需要數據庫自動隨系統啟動，一句非常簡單的話，但是拿給DBA來說至少得多花半個小時的時間來配置實現這個功能。那麼今天你看完這篇文檔之後，可以在他的話還沒有說完就可以完成自啟動的配置，非常簡單。

一、配置自動

1、添加啟動項
[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、創建並編輯啟動文件
[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、重啟驗證:




三、確定數據庫和EM以及監聽是否都已經起來

###監聽狀態
[oracle@db01 ~]$ lsnrctl status

###數據庫狀態
SQL> select instance_name,host_name,status from v$instance;

INSTANCE_N HOST_NAME  STATUS
---------- ---------- ------------
woo        db01       OPEN


###EM狀態
[oracle@db01 ~]$ emctl status dbconsole

至此我們已經確定，這樣也可以將數據庫配置為自動啟動，且比Oralce推薦的老方法更為簡單，老方法見如下鏈接：
