收到開發人員的變更郵件申請，需要在某個表增加字段，由於我們的環境ddl是沒有開啟的。用的訊息中介軟體kafka做傳輸消費，應用到目標庫。由於緊急變更，先做字段變更吧。
變更完成後，檢視ogg狀態；

手工停止該錶用到的程序，抽取和投遞均停止後，等待郵件報錯，找到對應的目標端機器；
找到kafka位址為10.1.x.9的位址，登陸機器

源端進行操作，先將原來的defgen檔案轉存乙份加時間日期。
[oracle@bapdb1 ggs12]$cd dirdef/
[oracle@bapdb1 ggs12]$mv defgen75_3.def defgen75_3.def_0531
[oracle@bapdb1 ggs12]$ pwd
/ggs/ggs12
[oracle@bapdb1 ggs12]$defgen paramfile ./dirprm/defgen75_3.prm
生成新的defgen75_3.def檔案，傳送到目標kafka伺服器中，
然後在目標庫中新增字段操作！
最後kafka目標機中ogg程序啟動即可，

看我把firefox改造成chrome的樣子
一直很喜歡chrome的主題，美觀，而且足夠簡介實用，標題欄和選單欄，狀態列都乾掉了，節省了很大的空間，尤其是對我這種小螢幕的電腦來說太棒了 昨天把firefox折騰成很想chrome的樣子了，跟大家分享一下，先看圖吧。如果你覺得好的花就下面看看我的做法吧 主題 乙個國人寫的firefox擴充套件，...
