Hi,

I'm trying to install Rapid Miner server to a windows 10 server.

 

the installation was successful, but when opening the standalone file an error occurs:

 

Calling "C:\Users\Full-\Desktop\rapidminer-server-installer-8.0.1\bin\standalone.conf.bat"

Setting JAVA property to "C:\Program Files (x86)\Java\jre1.8.0_131\bin\java"

Press any key to continue . . .

 

I already increased the RAM of the machine to 12GB and am running on a 64bit windows os.

    Hi Dana,

     

    the problem here is that you are running the application with a 32bit JRE that only supports ~1.5GB of main memory. This is a Java limitation and you need to download and install a 64bit JRE of Java 8. Once this is done please edit "<RM-SERVER-DIR>\bin\standalone.conf.bat" at line 36 where it states the path to your local JRE (in your case "C:\Program Files (x86)\Java\jre1.8.0_131"). Please provide the new path of the 64bit version here which might look like "C:\Program Files\Java\jre1.8.0_151".

     

    Cheers,

    Helge

    Hi Helge, thanks for your reply!

     

    I already had a java 64 bit version, but I tinstalled the one you suggested and I still get the same error:

    Hi Dana,

     

    as Helge pointed out in the second part of his post it is necessary that you edit the path to your Java within the file

    "C:\Users\Full-\OneDrive\Documents\rapidminer\bin\standalone.conf.bat"

    (see line 1 of your pasted log) which is called in your process.

    At line 36 where it states the path to your local JRE (in your case "C:\Program Files (x86)\Java\jre1.8.0_131"). Please provide the new path of the 64bit version here which might look like "C:\Program Files\Java\jre1.8.0_151"

     

    Best,

    Edin
