Hi,

could anyone tell me how to increase the java heap space size of the rapid miner application on a MAC pc?
I tried to edit the scripts/rapidminer.txt file and the scripts/rapidminer_gui.txt file by changing the #MAX_JAVA_MEMORY variable from 64mb to 2056mb but this action didn't help. After loading the rapidminer gui again, still 64mb RAM were dedicated for the rapidminer application which isn't sufficient for my application.

Thanks in advance
Geert

    Hi Geert,

    basically it should work as follows:

    1. edit the scripts/RapidMinerGUI file
    2. change the line you mentioned e.g. to 
    MAX_JAVA_MEMORY=1024
    3. be careful that the charakter [tt]#[/tt] is deleted, since this character indicates a comment in the file
    4. restart RapidMiner by executing the file scripts/RapidMinerGUI (therefore the script has to be executable!)

    Then it should work. The same should hold for the command line version scripts/rapidminer.
    Kind regards,
    Tobias
