I’ve come across this old but very handy option in Oracle JDeveloper. Basically it’s something I find very useful but often forget how to turn it on.
Open the jdev.conf file assiociated with Oracle JDeveloper. This file should be in the jdevmwhome/jdeveloper/jdev/bin folder.
At the end of this file add the following option.
AddVMOption -DMainWindow.MemoryMonitorOn=true
Once restarted you’ll have a nice memory overview at the bottom right of your screen.
It even allows you to force a garbage collection, just in case you are running close to memory limits.
