Nodefly

一個線上監控雲端伺服器服務的網站,透過簡單的指令安裝Agent後即可監控主機上的服務,目前監控看起來滿多樣化的∼
下面是網站上的介紹:

NodeFly - Providing real-time monitoring across cloud instances

  • Fast Set up - One line install so you can be monitoring in literally seconds
  • Unified Dashboard - Visualize all your data in one location

  • Monitor what is important to ensure applications stay up and running
  • Gain real-time insight into capacity utilization and instantly see how changing usage affects performance
  • Ensure instances aren't over or underutilized
  • Dig deep into you services layer to optimize your app performance

Simplicity is the key. NodeFly has developed "active discovery" which will proactively find and setup monitors for all of your available services.

We allow our users to gain detailed, real-time performance monitoring of cloud and application services so they can see everything that is happening, as it happens. From understanding system usage at every moment in time to uncovering and resolving issues within the application as they arise.

NodeFly makes adding servers from any of our 8 supported clouds takes seconds. All you do is add your API details and we pull all your details for you. Adding physical servers is also a snap; just install the NodeFly Agent.

Oracle LISTAGG

同事介紹的一個Oracle的好用查詢:LISTAGG
SELECT A.GROUP_ID,A.KEY, LISTAGG(A.VALUE,'; ')WITHINGROUP(ORDERBYA.VALUE)as GG  fromSYS_PROPERTIESaGROUP byA.GROUP_ID,A.KEY
LISTAGG可以將group後的結果會總顯示於一個欄位 上述SQL原本A.VALUE會是一個row一個row的排列 使用LISTAGG之後,可以將A.VALUE顯示在同一個row中 並且可以指定間隔符號(在此設定為';') 針對某一些報表查詢非常有用唷 :D

Flashback Query

感謝我的好友提供的: 在Oracle好用的指令...
Flashback Query: 讓異動過的資料表回到歷史時間點 Step 1. è
show parameter undo_retention  PS: 這個參數顯示系統上設定歷史保留時間(ex: 900 = 900秒) Step 2. è CREATETABLE XXXXX_0815 ASSELECT *  FROM XXXXXASOFTIMESTAMPTO_TIMESTAMP('2011-08-15 12:00:00','YYYY-MM-DD HH24:MI:SS');
PS: 透過as of timestamp方式取出該時間點的表格資料

Xoom 3.2 Upgrade

雖然Xoom早已經更新到3.2 但是台灣遲遲沒有更新版本@@ 終於按奈不住好奇心了... XDA上找到給604(台版Xoom)的3.2版本ROM(美版的) 動手刷拉~~ 出奇的順利阿... 下面是兩個相關網址:

我這邊是刷第二各網址下載的3.2 ROM(http://www.mediafire.com/?adsa081m3z8uykd) 3.1的就沒去測拉... 也沒有再去破解(遲早的ㄅ:P)
使用心得: 1. 順~比3.0操頻還順 2. 原生就支援micro-sd 3. 目前看是不支援USB...缺憾@@ 4. 因為美版的關係,所以有Books跟Videos兩個APP,但是因為網路地區的關係不能用就是了... 5. 沒有原生中文輸入法,不過對我沒差...我都用Google拼音 :D
