Java SE >= 8


1º - Download the latest JCL release on our Dowload page:

1.1 - Click "Downloads'

1.2 Then click at the  "JCL server/client binaries" link to download the ZIP with the deployable module binaries from the latest JCL release

Note: The image below shows th process being done using 7-zip, but you can se another program

From this point on, the next sessions are completely optional. The JCL now has a simpler deploy that enables the Server discovery and auto start when it's not found, thus you don't need to start the server neither specify it'ts adress at the configuration file. All you need to do is start a Host and this process will be performed. For more information on this, go to How to Start a Host on Windows . If you still want to start the Server explicitly, you can continue this tutorial to through the next sessions

3º - In 'jcl_JARS_pacu" folder click on Server.bat

After performing step four, a command prompt window will open. If everything goes well, the "JCL server ok" message will print


JCL bat and sh files to start Server, Super-peers and Hosts configere Java heap. By default JCL configures 2GB, as the figure below illustrates. JCL BIG Sorting requires ate least 8GB per JCL host, since ir executes Terabytes of data. Raspberry Pi clusters normally requires 128 or 256 megabytes for Java heap. Just NOT FORGET TO CONFIGUTE THE JAVA HEAP ACCORDING TO YOUR NEEDS!!
