限制 Java 堆空间,以便全局玩框架
2022-09-01 08:17:40
我有一个非常旧的Linux系统,并安装了java和play框架。当我运行java时,我得到:
java -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
所以我限制了 application.conf 中的 java 堆空间:
jvm.memory=-Xmx256M -Xms256M
有了这个设置,我可以运行播放测试,播放运行等...
但我不能运行:
play dependencies
~ _ _
~ _ __ | | __ _ _ _| |
~ | '_ \| |/ _' | || |_|
~ | __/|_|\____|\__ (_)
~ |_| |__/
~
~ play! 1.2.1, http://www.playframework.org
~
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
是否有全局配置文件或环境变量,我可以在其中限制java堆空间全局以用于Play框架?
更新:此外,以下内容不起作用:
play dependencies -Xmx256M -Xms256M
~ _ _
~ _ __ | | __ _ _ _| |
~ | '_ \| |/ _' | || |_|
~ | __/|_|\____|\__ (_)
