（解決了！通過僞造系統隨機生成，見下文）的Weblogic啓動緩慢（11mins）VM（VirtualBox和VMware的）
我設置了一個虛擬機圖像我的dev /建隊下。在該虛擬機內部，Weblogic域應該正在運行。我使用Ububtu服務器發行版，WLS 9.2MP3 + ALSB。
一切正常，相當快，但在開始時間WLS停止兩次可測量的時間。總共兩站的延遲時間約爲10分鐘。對於部署需要重新啓動服務器的任務，這非常煩人。 :-(
睡眠時間不是恆定的，有時在服務器啓動速度非常快，有時馬馬虎虎，有時10分鐘以上。
有趣的是，如果我按Enter鍵，同時觀察停止服務器，它喚醒WLST（Weblogic Jython shell）在VM中執行時也掛了很長一段時間，但它並沒有對Enter做出反應
這裏必須是一些開發人員運行WLS我想知道別人是否有同樣的問題？有人能解決嗎？
這裏的服務器的輸出（只是一個案例）：
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04)
Java HotSpot(TM) Client VM (build 1.5.0_12-b04, mixed mode)

UPDATE
我想我已經得到了軌道：它必須是randon種子初始化。這可以解釋爲什麼生成鍵盤事件釋放服務器。我所做的線程轉儲，並且一個線程處於可運行狀態，但等待：

感謝您發佈更新，但實際上您應該將解決方案作爲答案發布並接受它。 – 2010-04-01 21:32:03
謝謝，會做。我覺得這對自己來說有點不健康---) – 2010-04-02 00:12:54
事實上，它被鼓勵，特別是如果你找到了解決方案（你甚至可以使用SO作爲個人技術博客，使用危險風格）。 – 2010-04-03 00:45:16
