As far as I know you can only change the JVM.

Example I use this:

eclipse -clean -vmargs -Xverify:none -XX:+UseParallelGC -XX:PermSize=20M
-XX:MaxNewSize=32M -XX:NewSize=32M -Xms128M -Xmx256M

Thanks in Advance...

Sorry.. for the most part you will only need to specify the start and
max size by using -Xms -Xmx. Of the two definitely specify -Xmx. I
think if you specify both it is better to specify the same size. More
than likely to round out the paging activity.

I have the -clean -vmargs specified in my window shortcut that start
Eclipse.

Just to let you know, I do not keep the -clean option on the param exec
list all of the time. I only specify if I had just installed anything
into Eclipse and on fresh installations. After that I take it off.

This makes sure that Eclipse knows about all of the plugins you just
installed, If you watch all of the problems people have after installing
plugins in the Eclipse newsgroups. 70% of the tine will be resolved by
reloading Eclipse with the clean option. You can leave it in all of the
time but requires much more time to load up naturally because of all the
verification it is doing. It is verifying\rewriting plugin information
in projects and etc.

> eclipse -Xms256M -Xmx512M

Even if i do this i get: "Exception in thread "main"
java.lang.OutOfMemoryError: Java heap space"...

Right before I get this exception I have:
Free memory: 18672 / 66650112 / 66650112

from:
Dara.gui.write2Console("Free memory: " + Runtime.getRuntime().freeMemory()
+
" / " + Runtime.getRuntime().totalMemory() +
" / " + Runtime.getRuntime().maxMemory());

What is wrong?

on the run command, set them in your options arguments | vm arguments
box.

This will only apply to program run in Eclipse. In regular java they
are not permanent settings. You specify them on the java.exe command
line each time you run.
