OC4J 10.1.3 java.lang.OutOfMemoryError：PermGen空間

Question

在Win XP 32位操作系統（4GB）機器上嘗試在OC4J 10.1.3上部署War文件時，出現OutOfMemoryError。 Sun Solaris上OC4J 10.1.3的配置相同，war文件得到正確部署。

我沒試過提供下面的鏈接推薦：

https://community.oracle.com/thread/616067

但是沒能解決問題。請問有人可以就此問題提供更多建議嗎？

的oc4j_opmn.xml是這樣的：

<ias-component id="OC4J"> 
    <process-type id="home" module-id="OC4J" status="enabled"> 
     <module-data>

真的很感激任何形式的建議。

謝謝

java.lang.OutOfMemoryError通常表明你正在嘗試運行該程序需要更多的內存比你分配給它。嘗試將XX:MaxPermSize=128M加入像XX:MaxPermSize=1G這樣的大片，看看它是否有幫助。
