Hello @Mateus Silva Menezes​,


It seems that your system was low on memory and the JVM (Java virtual machine) could not find 2GB of RAM to run.

Try to close some applications before trying to run again.

You may also lower the maximum memory size for the JVM by editing spoon.bat (look for the -Xmx argument). But note that this will, most probably, have a huge impact on PDI performance.

Hello @Sergio Ribeiro​ ,


Thank you very much I tested the change in memory and the Pentaho initialized.
