How to install Knime server and Webportal

#1

Hi Team,

We are able to successfully installed Knime Desktop and Webportal with licenced key in Linux.

But when we started executing existing example workflows in Knime Webportal we are facing below error:

We tried to debug using log files and came to know that some RMI files are not installed or executed, it’s a configuration error.

Log File :
An error has occurred. See the log file
/home/rohit/Documents/knime/workflow_repository/runtime/runtime_knime-rmi-50100/.eclipse/1173489313_linux_gtk_x86_64/configuration/1561437845552.log.
Also check log file in /home/rohit/Downloads/knime_3.7.2/configuration

Dear @RameshK,

can you check that the extension “KNIME Server Executor (server-side extension)” is installed for your executor, as stated in https://docs.knime.com/2018-12/server_installation_guide/index.html#_knime_server_executor_configuration.

Best,
Marten
