推荐答案

你应该能够使用这篇文章中的信息。

You should be able to use the information found in this post.

-Xmszzzm

其中zzz是您的最小尺寸。

where zzz is your minimum size.

-Xmxzzzm

其中zzz是你的最大尺寸。

where zzz is your maximum size.

JAVA_OPTS="-Xms128m -Xmx512m"

您可以在VM args上找到更多信息此处。

You can find more info on VM args here.

如何在您的环境中全局设置它取决于您的操作系统。您使用的是哪种操作系统？

How to set it globally in your environment depends on your operating system. Which OS are you using?

编辑：我现在看到ubuntu标签。

EDIT: I see the "ubuntu" tag now.

您应该能够将JAVA_OPTs行放在 etc / environment 中。修改 etc / environment 后，您必须注销并重新登录才能使更新的环境变量生效。

You should just be able to put the JAVA_OPTs line in etc/environment. Once you modify etc/environment, you'll have to log out and back in for the updated environment variables to take effect.
