Hi,

which operating system are you using? How exactly do you start RapidMiner?

Best regards,
Marius

This page explains how to increase the maximum amount of memory via environment variables:

Hi,

oh my, what happened to the pictures on that page

(oh, just had to press Ctrl+F5, nvm ;D)
Anynway, this is a little odd, as the .exe file in the RapidMiner 64-bit version should allocate 90% of your available memory on a 64-bit windows..
To circumveit your problem you can however use the RapidMinerGUI.bat start script from the RapidMiner/scripts folder. Right-click, select edit, change


MAX_JAVA_MEMORY=1024

to the amount of RAM (in MB) you desire), e.g.


MAX_JAVA_MEMORY=4096

for 4GB of RAM. Then just launch the .bat script (NOT the .exe) to start RapidMiner, and you should have the specified amount of RAM available. If that is not the case, you have the MAX_JAVA_MEMORY environment variable set to something else and you will need to alter or delete it.

Hi again
I first opened rapidminer from the RapidMinerGUI.bat in the script file and when i checked the system monitor it showed that the max had increased to 1024MB which is good but the total also showed 1024MB this was just when opened surely the total should not be this high yet. I then tried to increase the MAX_JAVA_MEMORY but was not allowed to save these changes, how do i go about this.

Hi,

Total and Max do not show the current memory consumption, they only show the amount of RAM currently available to RapidMiner and the theoretical meximum amount of RAM RapidMiner will use if needed. The current memory consumption is indicated by the graph. For the permissions issue when editing please see the link Retegniw posted.
