获取“Java堆空间”时的Eclipse内存设置和“内存不足” [英] Eclipse memory settings when getting "Java Heap Space" and "Out of Memory"

问题描述

当尝试在eclipse中启动并运行flex / java项目时，我使用Eclipse，Tomcat和JRE，不断获得Out of Memory Exception和Java Heap Space。

在研究尝试调整内存设置时，我找到三个调整位置的地方：

• Eclipse.ini




• 窗口>首选项下的JRE设置




• Catalina.sh或Catalina.bat

在这些不同的地方设置-xms和-xmx有什么区别，是什么意思？ >

有没有办法验证这些内存设置是否相应设置？

什么是最优的-xms和-xmx

任何其他内存提示？

谢谢。

解决方案

-xms是启动内存（在VM启动时），-xmx是VM的最大内存

• eclipse.ini：运行eclipse的VM的内存


• jre设置：从eclipse运行的java程序的内存


• catalina.sh：tomcat服务器的内存

When trying to launch and run a flex/java project in eclipse I kept getting a "Out of Memory Exception" and "Java Heap Space" using Eclipse, Tomcat and a JRE.

While researching trying to adjust the memory settings I found three places to adjust these:

• Eclipse.ini

• The JRE Settings under Window > Preferences

• Catalina.sh or Catalina.bat

What are the differences between setting -xms and -xmx in these different places and what does is mean?

Is there any way to verify these memory settings are being set accordingly?

What are the optimal -xms and -xmx settings for a computer with 2gb of RAM?

Any other memory tips?

Thanks.

解决方案

-xms is the start memory (at the VM start), -xmx is the maximum memory for the VM

• eclipse.ini : the memory for the VM running eclipse
• jre setting : the memory for java programs run from eclipse
• catalina.sh : the memory for your tomcat server
