Eclipse Heap Size

[Somnath Mallick]

Hi Everyone,

Few days ago i had problems with my Eclipse running out of memory, and so i increased it but somehow the heap size shown at the bottom of Eclipse still remains the same. My current eclipse.ini file is something like this:

-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
org.eclipse.epp.package.jee.product
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
768m
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms256m
-Xmx512m
-Dsun.lang.ClassLoader.allowArraySyntax=true

I increased the heap size to 768MB and still the heap size is shown as 495MB. Could you tell me how to increase the heap size of Eclipse permanently?

-Xmx512m  

This should be the JVM parameter that sets the maximum (mx) heap size.

Oh.. ok! I changed it to 1024MB and the 768MB to 1024MB and Eclipse failed to start. Gave an exception of Exit Code 1 or something. So i changed it to lower values.
