Execute failed: Java heap space

Good morning.
when I join 2 very large tables, of 6 million and 4 million records respectively, the processing gives me an error like "Execute failed: Java heap space.
what can I do?

Hi @menc

Have a look in the knimi.ini file that is located in the root directory of your KNIME installation. Check the value of -Xmx. A recommend pratice is to set this to about 70-80% of your available RAM.


The above example reflects 8 GB.
