如何为Netbeans分配更多的内存? [英] How to assign more memory to Netbeans?

问题描述

我的PC上有24 GB的RAM，但是有时Netbeans编译我的项目时，它说没有足够的内存来编译它，我查看了内存使用情况，它显示为:586/590 M.

I have 24 GB of RAM on my PC, but sometimes when Netbeans compiles my projects, it says not enough memory to compile it, I looked at the memory useage, it shows : 586/590 M.

那么如何告诉Netbeans，有足够的RAM，可以根据需要使用多少内存?

So how to tell Netbeans, there are plenty of RAM, use as much as you need ?

推荐答案

在Netbeans-Home下的 etc 目录中，编辑文件 netbeans.conf . -Xms 和 -Xmx 应该增加到允许您的程序进行编译的值.

In the etc directory under your Netbeans-Home, edit the file netbeans.conf file. -Xms and -Xmx should be increased to the values that allow your program to compile.

这是 netbeans.conf 中的说明:

# Note that default -Xmx and -XX:MaxPermSize are selected for you automatically.
# You can find these values in var/log/messages.log file in your userdir.
# The automatically selected value can be overridden by specifying -J-Xmx or
# -J-XX:MaxPermSize= here or on the command line.

将值放入 netbeans_default_options 字符串中.这是我的(删除换行符，为提高可读性而添加):

Put the values in the netbeans_default_options string. Here is mine (remove linebreaks, added for readability):

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m 
-J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true 
-J-Dsun.java2d.noddraw=true -J-Dsun.java2d.dpiaware=true 
-J-Dsun.zip.disableMemoryMapping=true  -J-Dsun.awt.disableMixing=true 
-J-Dswing.aatext=true -J-Dawt.useSystemAAFontSettings=lcd --laf Nimbus"

编辑:-J-Xms设置最小Java堆大小，-J-Xmx设置最大Java堆大小.

-J-Xms sets the minimum Java heap size, -J-Xmx sets the maximum Java heap size.
