Question

尝试在Win XP 32位操作系统（4GB）计算机上的OC4J 10.1.3上部署War文件时，我得到OutOfMemoryError。在Sun Solaris上使用相同的OC4J 10.1.3配置正确部署war文件。

我确实尝试了以下链接中提供的建议：

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

然而无法解决问题。有人可以就这个问题提出更多建议吗？

oc4j_opmn.xml是这样的：

<ias-component id="OC4J">
    <process-type id="home" module-id="OC4J" status="enabled">
      <module-data>
  <category id="start-parameters">
          <data id="java-options" value="-server -XX:MaxPermSize=128M -ms512M -mx1024M -XX:AppendRatio=3 -Djava.security.policy=$ORACLE_HOME/j2ee/home/config/java2.policy -Djava.awt.headless=true -Dhttp.webdir.enable=false"/>
        </category>
        <category id="stop-parameters">
          <data id="java-options" value="-Djava.security.policy=$ORACLE_HOME/j2ee/home/config/java2.policy -Djava.awt.headless=true -Dhttp.webdir.enable=false"/>
        </category>
      </module-data>
      <start   timeout="600" retry="2"/> 
      <stop    timeout="120"/>
      <restart timeout="720" retry="2"/>
      <port id="default-web-site" range="12501-12600" protocol="ajp"/>
      <port id="rmi" range="12401-12500"/>
      <port id="jms" range="12601-12700"/>
      <process-set id="default_group" numprocs="1"/>
    </process-type>
</ias-component>

真的很感激任何建议。

谢谢

java.lang.OutOfMemoryError通常表示您尝试运行的程序需要的RAM多于分配给它的RAM。尝试将XX:MaxPermSize=128M扩展为类似XX:MaxPermSize=1G之类的内容，看看它是否有帮助。

OC4J 10.1.3 java.lang.OutOfMemoryError：PermGen空间
