增加Eclipse的JVM最大堆大小 [英] Increase JVM max heap size for Eclipse
问题描述
eclipse.ini
或通过命令行中指定,但不工作。 我的最大堆大小具有完全相同的限制(运行jconsole)和之后( System.out.println(java.lang.Runtime) getRuntime()。maxMemory());
)启动Eclipse。 1.8G
- 在启动JVM堆大小之前是否有任何方法修改(例如,配置文件?)
- 当指定堆大小为Eclipse时,我可能做错了什么?
这是命令:
./ eclipse / eclipse -debug -consoleLog -vmargs -Xms1000m -Xmx6000m -XX:-UseGCOverheadLimitcl
这是我的 eclipse.ini
(这些值被指定的eclipse启动参数覆盖):
-startup
plugins / org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins / org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120522-1813
-product
org.eclipse.epp.package $。
- b --launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion = 1.6
-Dhelp.lucene.tokenizer = standard
-XX:MaxPermSize = 6000m
-Xms1000m
-Xmx6000m
可以使用命令行选项增加Java虚拟机(JVM)分配的堆大小。
-Xms< size>设置初始Java堆大小
-Xmx< size>设置最大Java堆大小
-Xss< size>设置java线程堆栈大小
如果使用tomcat服务器,可以通过进行更改堆大小到Eclipse /运行/运行配置并选择Apache Tomcat / your_server_name / Arguments,并在VM参数部分下使用以下内容:
-XX :MaxPermSize = 256m
-Xms256m -Xmx512M
如果您没有使用任何服务器,在运行代码之前,可以在命令行中键入以下内容:
java -Xms64m -Xmx256m HelloWorld

I am trying to increase the max heap size for my Eclipse. I have tried specifying in eclipse.ini
or through the command line, but are not working.
My max heap size has the exact same limit before (running jconsole) and after (System.out.println(java.lang.Runtime.getRuntime().maxMemory());
) starting Eclipse. 1.8G
- Is there any way to modify JVM heap size before it is launched (ex. a config file?)
- What could I be doing wrong when specifying heap size to Eclipse?
This is the command:
./eclipse/eclipse -debug -consoleLog -vmargs -Xms1000m -Xmx6000m -XX:-UseGCOverheadLimitcl
This is my eclipse.ini
(which values are overwritten by the specified eclipse launching parameters):
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120522-1813
-product
org.eclipse.epp.package.java.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Dhelp.lucene.tokenizer=standard
-XX:MaxPermSize=6000m
-Xms1000m
-Xmx6000m
It is possible to increase heap size allocated by the Java Virtual Machine (JVM) by using command line options.
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xss<size> set java thread stack size
If you are using the tomcat server, you can change the heap size by going to Eclipse/Run/Run Configuration and select Apache Tomcat/your_server_name/Arguments and under VM arguments section use the following:
-XX:MaxPermSize=256m
-Xms256m -Xmx512M
If you are not using any server, you can type the following on the command line before you run your code:
java -Xms64m -Xmx256m HelloWorld
