Jakarta ee 无法启动Glassfish 3.1:java.io.IOException:错误=12，无法分配内存

我刚从A2Hosting购买了一个Ubuntu9.0.4VPS（256MB的专用RAM（512MB的Burstable）），并尝试在上面安装一个Glassfish服务器。当我尝试

asadmin start domain

时，我遇到了这个错误

JVM failed to start: java.io.IOException: Cannot run program "/usr/local/jdk1.6.0_22/bin/java" 
(in directory "/home/harry/glassfish3/glassfish/domains/domain1/config"):
java.io.IOException: error=12, Cannot allocate memory
Command start-domain failed.

以下是

命令的结果

尝试减少-Xmx512m行中的金额，直到您得到一些有效的东西。然后联系您的提供商，看看您的限制在哪里。

它包含大约400行代码，我有与

jvm

相关的东西，如果您想查看全部内容，请让我知道。

-Xmx512m

代表什么，普雷斯顿？试着减少到

64m

，它仍然不起作用。我购买的VPS具有

256 MB专用RAM（512 MB Burstable）

。还有别的想法吗？谢谢，manXmx是您的最大堆大小。Xms是您的初始堆大小。也许您需要显式地将Xms设置为256。请记住，最低要求是1GB的RAM。但是，我有在512上运行的实例。您还可以查看旧的2.1性能调优指南。3.0版似乎还没有。man最低要求为1GB内存。我不知道。所以你认为错误

无法分配内存是因为我没有足够的内存？我尝试将
-Xms128m
添加到
domain.xml
，但它仍然会给我相同的错误。您的问题肯定与系统试图分配的内存比它的内存多有关。如果您无法通过调整Xms、Xms选项使其工作，那么您应该尝试将可用RAM增加到最小。
