You can change default jvm args which will apply to all Run/Debug configurations and you don't have to change individual configuration.

In eclipse go to Window -> Preference -> Java -> Installed JREs -> Edit default JRE. There add -XX:MaxPermSize=512m under Default VM arguments

  1. Click the arrow next to the run button, and select Run Configurations...
  2. Select your application from the left list
  3. Go to Arguments
  4. In VM arguments add -Xmx6g -Xms2g
  5. Click Apply.

This will increase the heap size for that launch configuration to 6G.

Try changing in the eclipse.ini file. Here is an example configuration

-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.v20120913-144807
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Xms512m
-Xmx1024m
-XX:+UseParallelGC
-XX:PermSize=256M
-XX:MaxPermSize=512M
