无效的最大堆大小 [英] Invalid maximum heap size

问题描述

我已经从另一个位置复制了一个jdk目录.从那时起，我收到以下错误消息.

I have copied a jdk directory from another location. Since then, I get the following error message.

Your environment has been set.

Invalid maximum heap size: -Xmx5096m
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.

这是否意味着我将不得不重新安装jdk，而不仅仅是复制任何安装目录?我要的是这个问题，而不是自己尝试尝试，因为该练习必须在客户端计算机上完成.

Does this mean I will have to re-install the jdk, and not just copy any installation directory? I'm asking this and not trying it out myself because this exercise will have to be done in a client machine.

当前计算机是Windows 2008服务器，并且具有 12GB 的RAM.

The current machine is a Windows 2008 server and has 12GB of RAM.

推荐答案

您正在使用32位VM(Java HotSpot(TM)客户端VM)，该VM可以映射到最大4G(实际上只有2 GB)2 ^ 32地址位置最大Java堆64位操作系统上的32位JVM的大小

You are using 32 bit VM (Java HotSpot(TM) Client VM) which can be mapped to maximum 4G (Only 2 GB in reality) 2^32 address locations Maximum Java heap size of a 32-bit JVM on a 64-bit OS

无效的最大堆大小:-Xmx5096m指定的大小超出了可表示的最大大小.

Invalid maximum heap size: -Xmx5096m The specified size exceeds the maximum representable size.

您可以修改-Xmx参数以使用anythinng< = 2g应该可以在这里工作

You can modify the -Xmx parameter to use anythinng <=2g should work here
