How do I increase the heap size available to Eclipse/MyEclipse?

How do I increase the heap size available to Eclipse/MyEclipse?

Some JVMs put restrictions on the total size of memory available on the heap space. If you are getting Out of Memory Warning while running Eclipse/MyEclipse, the VM prompt corresponding box and let the heap grow to a larger amount by passing the -vmargs command to the Eclipse launcher.

For example, the following command would run Eclipse with a heap size of 512MB,

eclipse [normal arguments] -vmargs -Xmx512M [more VM args]

1. Sometimes, the changes which are done in eclipse/MyEclipse will reflect and heap size increase. If it fails just go with step 2.

2. Change as below in the eclipse.ini/myeclipse.ini file which is located in the installation path,

-install
...,
configuration
-vmargs
-Xmx1024m
-XX:MaxPermSize=256m
-XX:ReservedCodeCacheSize=64m

And this will increase heap size to 1024MB.
