“此平台不支持运行64位JVM".在64位linux上使用java -d64选项 [英] "Running a 64-bit JVM is not supported on this platform" with java -d64 option on 64bit linux

问题描述

我有一个64位linux操作系统:

I have a 64 bit linux os:

$ uname -p
x86_64

列出的java -version:

java -version listed:

java version "1.6.0_43"
Java(TM) SE Runtime Environment (build 1.6.0_43-b01)
Java HotSpot(TM) Server VM (build 20.14-b01, mixed mode)

我正在尝试以4096分钟的堆大小运行64位的jvm(这是一个重量级的应用程序).当我添加-d64选项时，我收到消息

I am trying to run a 64 bit jvm with 4096 min heap size ( Its a heavy weight app ). When i add -d64 option i get the message

Running a 64-bit JVM is not supported on this platform

如果没有-d4选项，并且堆大小为2048，则可以正常工作.但是内存不足，因此我需要将64位JVM与4Gigs配合使用.谁能告诉我为什么它不接受d64吗?

With out -d4 option and with heap size 2048 it works fine. But the memory isnt enough so i need to use 64 bit JVM with 4Gigs. Can anyone tell me why its not accepting d64 ?

推荐答案

感谢@Adi Dembark和@nos发现了问题.确实是32位的jvm.更改为64位固定.

Thanks @Adi Dembark and @nos found the issue. It was indeed a 32 bit jvm. changing to 64 bit fixed it.
