Double KNIME Server instance running in parallel

Hello,

I would like to run 2 instances of KNIME Server on the same Ubuntu Server. Just for testing purpose (no workflow execution)

When I start the second instance, it stops immediately.

Any idea ?

Thanks

Hi Jerome,

Two running KNIME Server running parallel on the same machine means two running Tomcat instances using the same communication ports. The first server instance get the ports, the second won’t as they are already occupied. Therefore the start fails.
We don’t recommend such a setup as even if the main used network ports are changed in the configuration files it might cause issues.

Best,
Michael
