永久增加java堆大小? [英] increase the java heap size permanently?

问题描述

有没有办法可以在我自己的计算机上为 jvm 设置默认堆大小?我想将它设置为 1g，因为我总是运行自定义程序，这些程序总是达到默认 jvm 大小的超额点.

Is there a way that I can set the default heap size for the jvm on my own computer? I want to set it to 1g, because I'm always running custom programs that always hit the overage point in the default jvm size.

我只是不想每次从命令行运行我的 Java 应用程序时都要记住输入 -XmX1g...

I just dont want to have to remember to type -XmX1g everytime I run my java app from the command line...

必须有一种管理方式才能做到这一点吗?

There has to be an admin way to do this right?

推荐答案

显然，_JAVA_OPTIONS 也适用于 Linux:

Apparently, _JAVA_OPTIONS works on Linux, too:

$ export _JAVA_OPTIONS="-Xmx1g"
$ java -jar jconsole.jar &
Picked up _JAVA_OPTIONS: -Xmx1g
