The files to modify
The following 2 files must be modified
here I have used the default installation folder that is proposed by JDev. If you have another just search the 2 files in hte installaiton folder.
Tweak the following lines
these are the setting I use and my jdeveloper.exe limits up to around 1200MB
Remember the limit of the mem that can me allocated to a java process in Windows is around 1.5Gigs.
These so if (Xmx + XX:MaxPermSize) around 1.5 gigs JDeveloper will not start and through a related jvm.dll error.
This is a common and old practice to increase memory of JDeveloper (back to the first days of 11g release when the mem leaks where creting pools of memory). These days are in to the past and the tool now behaves almost ideally.
Also if you machine is really old, decreasing history of JDeveloper might help a lot.
