Release Notes

KNIME Server 4.12 is a feature release of the 4.x release line. All clients that have worked with KNIME Server 4.11 will continue to work with KNIME Server 4.12 without restrictions.

To find out which version of KNIME Server you are currently running, you can check the Administration pages on the WebPortal.

New Features

For a list that includes the new Analytics Platform 4.3 features see here.

Highlighted new functionality is:

A detailed changelog for KNIME Server 4.12 is also available.

Java 11 support

KNIME Server 4.12 adds support for Java 11. While it is possible to continue using Java 8 for existing installations, we recommend the use of Java 11 for fresh installations. Note: Java 11 support is only confirmed for Tomcat-based installations of KNIME Server. TomEE-based installations should continue to use Java 8

Configuration for email notifications

Configuration for email notifications sent by KNIME Server has moved from the knime.xml file to knime-server.config. In order for email notifications to still work, please migrate your settings to the new location. This can be done at runtime, it is not necessary to restart KNIME Server.

Revised job states

Job state handling has been revised to be more consistent. Among other things, it is now easier to identify jobs that have failed. See here for a list of all job states.

New configuration options

Various new configuration options were added to KNIME Server to improve usability:

com.knime.server.job.max_schedule_failures=<number>: It is now possible to configure the number of attempts to create a job before a schedule is disabled. Set to -1 to deactivate auto-disabling of schedules. This was previously hardcoded to 3.

com.knime.server.gateway.timeout=<duration with unit, e.g. 30s, 1m>: Allows increasing the timeout for loading jobs in the Remote Editor. This was previously hardcoded to 20s

com.knime.server.action.job.force_discard_on_failure=<true|false> com.knime.server.action.job.force_discard_on_success=<true|false> com.knime.server.action.job.enable_discard_checkboxes=<true|false>: Automatic discarding of jobs after execution is now more flexible. Previously, it was only possible to discard jobs after successful execution. We have now added an option to also discard on failure. Default values for discard on success/failure can be configured using the first two options listed above. The third option allows the admin to enforce these settings by disabling the checkbox that would change the behavior.

Local file system access by KNIME workflows

A growing number of KNIME nodes are being revised to use a new shared framework for file access. More nodes will follow over the next releases, so that eventually the file access of all KNIME nodes uses the shared framework.

When executing on KNIME Server, a preference controls whether those nodes may access the local file system of the KNIME Server Executor or not. With this release, local file system access is disallowed by default (previously it was allowed).

To allow local file system access (not recommended), you can add the following line to the customization profile used by your KNIME Server Executor(s):

/instance/org.knime.filehandling.core/allow_local_fs_access_on_server=true

This preference affects all nodes that are part of the revised file handling framework. Old nodes that have not yet been ported to the new framework are not affected by this setting.

Introduction to the update process

This document guides you through the steps that are needed to upgrade an existing KNIME Server installation from version 4.11 to 4.12 or update by applying a bugfix to version 4.12.

You will find a complete guide to installing KNIME Server in the KNIME Server Installation Guide, and a complete description of all configuration options in the KNIME Server Administration Guide.

If you have any questions or need assistance with the update process, please contact your dedicated KNIME support specialist.

Since version 4.11, new installations of KNIME Server are based on Apache Tomcat, rather than Apache TomEE which was used in previous releases. In addition, we continue to offer a TomEE based installer for the time being and the TomEE version for this has been updated to version 8.0.3 (from TomEE 7.0.5).

You will need to perform a fresh installation of KNIME Server if:

  • You want to upgrade from a TomEE based installation to a Tomcat based one

  • You want to update to the newest TomEE version 8.0.3 from an older TomEE version.

You can instead follow the upgrade process explained in this documentation if you either want to upgrade from an older installation of KNIME Server that is already Tomcat based, or want to upgrade from an older installation of KNIME Server based on TomEE 7.0.5 but maintaining this older TomEE version.

In order to upgrade a TomEE-based KNIME Server, TomEE needs to be at least version 7.0.5. Older versions are not supported, and require a fresh installation.

KNIME Executors from version 4.3 are not affected by these changes, and can be updated following the standard procedure.

Due to some updated libraries, the KNIME Server REST API documentation available at https://<your-server>/knime/rest/doc/index.html does not work anymore in installations based on TomEE 7.0.5. If you need this functionality, please install a fresh KNIME Server, which is based on TomEE 8.0.3 (or move directly to Tomcat). This does not affect the per-workflow Swagger pages (right-click in KNIME Explorer > Show API Definition), which continue to work on all TomEE versions.
In addition, the newly-added Administration portal on KNIME WebPortal is read-only for TomEE 7.0.5 Servers. While configuration values are shown, you will not be able to modify them.

Prerequisites

Server

  • You have already KNIME Server 4.11.x or KNIME Server 4.12.x running.

  • A KNIME Server installation based on Tomcat application server

  • A KNIME Server installation based on TomEE application server of at least version 7.0.5.

You will not be able to upgrade to a Tomcat based installation or to update your underlying TomEE application server. If you want to perform one of these two operations you will need to perform a fresh KNIME Server installation.
For the sake of readability, this documentation uses <apache-tomcat>/ to refer to the installation directory of the server application. Apart from the directory name, the location will be the same on TomEE-based folders.

Client & Executor

  • KNIME Analytics Platform clients with KNIME ServerSpace 4.0+ otherwise it will not be able to talk to the Server.

  • KNIME Analytics Platform 4.3 as Executor with the corresponding KNIME Executor Connector extension version 4.12 installed on the Server side.

Backup

Even though all the data on the Server should be preserved during the update it is highly recommended to create a backup of all important data (see KNIME Server Administration Guide for backup information).

With KNIME Server 4.12 the email configuration moved from the knime.xml to the <knime-server-repository>/config/knime-server.config, so any existing custom configuration must be moved. More information concerning the email configuration can be found in the KNIME Server Administration Guide

Upgrade/update steps

Application server upgrade/update

Start by downloading the following files and make sure that the owner of these files is your KNIME user:

  • The <knime-tomcat>.jar file listed here

  • If you are updating using Tomcat: the latest Tomcat .war file listed here

  • If you are updating using TomEE: the latest TomEE .war file listed here

  • The latest KNIME Server Executor file listed here

Next backup these files before starting the update process:

  • The knime.xml file located in <apache-tomcat>/conf/Catalina/localhost/ Please be aware that the name of the file might be different if the .war file had a different name (e.g. com.knime.enterprise.server.xml or webportal.xml).

    Failure to backup this file will result in losing access to your scheduled jobs since it contains the secret key that is used to encrypt the schedule.

  • The server.xml file located in <apache-tomcat>/conf/

Then follow these steps:

  1. Stop KNIME Server.

    1. On Windows: If you have KNIME Server installed as a service, stop KNIME Server and Executor.

      If you don’t have KNIME Server installed as a service, then run the shutdown.bat file located in <apache-tomcat>/bin

    2. On Linux: If you have KNIME Server installed as a service, stop KNIME Server by running the systemctl stop knime-server.service command

      If you don’t have KNIME Server installed as a service, then run the shutdown.sh file located in <apache-tomcat>/bin

  2. Delete the existing folder <apache-tomcat>/webapps/knime. You may not have a folder with this name located in the webapps folder. If this is the case, delete the folder that matches the file name of the .war file located in the webapps folder. E.g. if you see a webportal.war file in the webapps folder, delete the webportal folder.

  3. Move the <filename>.war file located in the webapps folder to a different folder. Then copy the new downloaded war-4.12.x.y.war file to the webapps folder and rename it to <filename>.war.

  4. Check if the knime.xml file that you backed up before still exists. If not copy the backup to the previous location.

  5. Copy the downloaded file <knime-tomcat>.jar to <apache-tomcat>/lib. Delete the existing old <knime-tomcat>.jar file that was already in that directory.

Now you will need to follow the steps in the KNIME Executor update section to update the KNIME Server Executor, before starting Tomcat application server.

KNIME Executor update

KNIME Server 4.12 requires KNIME Analytics Platform 4.3 or later.

Updating from KNIME Analytics Platform 4.3.0

If possible, start the executor installation in graphical mode (using the correct installation user!). If you have internet access, go to File → Update KNIME… and it will suggest updating to the new version. Follow the steps in the wizard. If you don’t have direct internet access, you must download the zipped update sites from the commercial downloads page. Then register the ZIP files in File → Preferences → Install/Update → Available Software Sites and go to File → Update KNIME…​

Under Linux, if you cannot start the graphical user interface, you can use the update-executor.sh script that is in the root of the executor installation.

Call the script on the command line and provide a list of update sites that contain the new versions of the installed extensions and all installed extension will be updated (given that an update is available):

./update-executor.sh https://update.knime.com/analytics-platform/4.3

If you get error messages when executing update-executor.sh about missing "installable units", make sure that you have provided all necessary update sites.

If you want to selectively update only certain extensions, you have to build the update command yourself. An update is performed by uninstalling (-u) and installing (-i) an extension at the same time:

./knime -application org.eclipse.equinox.p2.director -nosplash -consolelog -r <list-of-update-sites> -i
<list-of-features> -u <list-of-features> -d <knime-installation-folder>

Upgrading from KNIME Analytics Platform 4.2.x and older

Due to some larger changes, it is not possible to upgrade to KNIME Analytics Platform 4.3.x from a version older than 4.3.0. Therefore, you need to install KNIME Executor 4.3.x version from scratch.

Before starting the KNIME Executor installation process create a backup of the <executor-folder> renaming it to <executor-folder>.old. After you succesfully install the desired version of KNIME Executor, rename the new folder containing the Executor installation to the old folder name.

Then proceed with the installation of KNIME Executor by downloading the KNIME Executor full build from here and extracting it. This installer includes all extensions required for running as an Executor for KNIME Server.

Alternatively you can also install KNIME Analytics Platform from scratch and install the KNIME Executor connector extension version 4.12 into it. In this case, you will need to run the newly installed KNIME Analytics Platform 4.3 instance as the user that owns the installation.

Please refer to the KNIME Server Installation Guide for more details about installing a KNIME Executor.

Upgrading using the standard procedures is possible again from KNIME Analytics Platform 4.3.1 onwards.

knime.ini file

In case you want to use custom settings from your old KNIME Executor’s knime.ini file, please copy only the lines following -vmargs to the new knime.ini. The only exception to this are the four lines related to Server Managed Customizations (-profileLocation…​), in case those are set. The remaining lines above -vmargs contain paths to resources that have been changed in the new release, so they are not compatible.

server.xml file

For fresh installations, please note that a server.xml file (<apache-tomcat>/conf/server.xml) from an older installation cannot be copied over due to some larger changes. Any custom changes applied to your existing server.xml need to be manually copied over to the new server.xml. For upgrades the existing server.xml continues to work, and does not need any adjustments.

Configuration of the updated KNIME Server

KNIME Server license

The KNIME Server license continues working with the new Server. If you haven’t received a license file or if it is not working correctly, please contact KNIME support or your dedicated KNIME account manager.

Enabling execution via Apache Qpid

KNIME Server 4.11 introduced an integrated message broker for communication between KNIME Server and KNIME Executor, based on Apache Qpid (https://qpid.apache.org/). This can be thought of as using an architecture that corresponds closely to distributed KNIME Executors, but runs on a single host, which is used by both KNIME Server and KNIME Executor.

Unlike distributed KNIME Executors, it is not necessary to install a separate message broker such as RabbitMQ. Instead, Apache Qpid is bundled as part of all KNIME Server installations. New installations of KNIME Server use Qpid by default. To switch your current installation to Qpid, changes are required in two locations:

Application Server

Activate queue in knime-server.config. The file can be found in <knime-server-repository>/config/knime-server.config. Set the parameter

com.knime.enterprise.executor.embedded-broker= to true

In addition, comment out the line com.knime.server.executor.knime_exe= by placing a # character at the start of the line.

KNIME Executor

In the KNIME Executor installation directory, add the following line to the knime.ini file, anywhere after the -vmargs line:

-Dcom.knime.enterprise.executor.msgq=amqp://knime:20knime16@localhost/

Unlike the RMI-based execution, using the Qpid message broker requires to startup KNIME Server and KNIME Executor separately. For starting up KNIME Server, you can still use the startup.sh/.bat file located in <apache-tomcat>/bin. For starting the Executor, you can use <executor directory>/start-executor.sh (Linux) or <executor directory>/start-executor.bat (Windows)

In case the Executor startup script is not present, you can start the Executor from command line by running

./knime -nosplash -consolelog -application com.knime.enterprise.slave.KNIME_REMOTE_APPLICATION

For setting up the KNIME Server service, please follow the steps outlined in the KNIME Server Installation Guide. Installing the Executor as a service follows the same procedure as described for distributed KNIME Executors.

For increased security, we recommend to run both services by different users.

Preferences file

Note that when switching from RMI to Qpid, the old preferences.epf file in ./workflow_repository/config is not used anymore. In order to set preferences on the Executor (e.g. database drivers or Python configuration), please use a preference profile as described in the KNIME Server Admin Guide.

Server temp directory

Switching to Qpid also uses a different temp directory than RMI. On Linux, this defaults to /tmp, which might have size restrictions. In order to manually set a different temp directory, please add the following to the knime.ini file of the KNIME Executor, anywhere below the -vmargs line: -Djava.io.tmpdir=/path/to/tmpdir

Qpid port

In some environments, it is necessary to explicitly open a port for connections to Qpid on localhost (even though Server and Executor are running on the same host). By default, the port is 5672. This can be changed in the knime-server.config file.

Server host name in /hosts

By default, the host name of the machine is available in /etc/hosts/. If this is not the case, KNIME Server will not work using Qpid. This can be resolved by adding the server’s host name to /etc/hosts/, e.g. 127.0.0.1 <hostname>.

Compressed responses

Due to a change in Tomcat responses sent by KNIME Server 4.11 and 4.12 are not compressed even though compression is configured in the server.xml. In order to enable compression again, you have to add the attribute noCompressionStrongETag=false to all <Connector> elements in your server.xml, e.g.

...
<Connector noCompressionStrongETag="false" compressibleMimeType="..." compression="on"/>
...

If you create a new server installation using the KNIME Server Installer for 4.12.4 this attribute will be added automatically.

Troubleshooting

All schedules are lost after updating

One important step during update process is the backup of the knime.xml file so that it can be copied back into the KNIME Server installation folder. The knime.xml file contains a secret key for encrypting the communication between the server and the installation folder. If this is not restored before starting the server, the server will not be able to load jobs and schedules previously created.

Access to KNIME WebPortal version > 4.11 is not possible

Access gives error 404

If you cannot access the URL of the KNIME WebPortal version > 4.11
https://<server-address>/knime/webportal/
and it fails with error 404, usually indicates that during update or installation process the Context Root used to define the KNIME WebPortal URL was left empty (/). This is not possible starting with the release of KNIME WebPortal version 4.11+ for which it is necessary to always specify a Context Root.

Please refer to the KNIME Server Installation Guide.

Access gives error 500

If you cannot access the URL of the KNIME WebPortal version > 4.11
https://<server-address>/knime/webportal/
and it fails with error 500, usually indicates that the update did not work as expected.

Please contact KNIME support team via support@knime.com to get this fixed.

Update of KNIME Executor via command line is not possible

This is a known bug when updating from a KNIME Server version 4.11.1. This bug is fixed starting with KNIME Server version 4.11.2.

To solve the issue you need to follow these steps:

  1. Create a copy of the file named knime.ini-copy

  2. Remove the -profileLocation option from the knime.ini file

  3. Update the KNIME Executor via command line

  4. After a successful update, overwrite your knime.ini file with knime.ini-copy.

If this solution does not work, please contact KNIME support team via support@knime.com

Workflows deployed on the server cannot be executed

  • If the following error message appears:

Unable to load workflow, it was created with a future version of KNIME

The KNIME Analytics Platform client with which you are connecting to the KNIME Server and with which the server was built needs to have a lower or equal version to the KNIME Executor. If this is not the case, please ask your KNIME Server Administrator to update the KNIME Server and/or KNIME Executor to the release version of the KNIME Analytics Platform client you are using locally.

  • If a missing node is reported, instead, check if the node is already installed and if the version of the respective extension is the same in both the KNIME Analytics Platform client and the KNIME Executor.

  • Finally, if your scripting (R or Python) snippets fail, it is possible that the respective packages are missing on KNIME Server. Please refer to the respective guides to install Python and R packages. Please also make sure the user under which you install those packages is the same user running the KNIME Executor.

Connection to KNIME Executor hosts after switching to Qpid is not possible

  • Make sure the hostname of the KNIME Server is mentioned in the /etc/hosts file

  • Check that the following ports are accessible on localhost. They do not need (and in fact should not) to be accessible from other systems (usually this is the case).

    • With RMI: com.knime.server.executor.start_port (default 60100)

    • With QPid: com.knime.enterprise.executor.embedded-broker.port (default 5672)

    • With RabbitMQ: For KNIME Server and for the KNIME Executor that is setup on a separate machine (default 5672)

  • Starting with QPid, KNIME Executor needs to be started manually. Please follow the instructions in the KNIME Server Installation Guide to do so.

  • It might be necessary to change the user running the service. Please follow the instructions in the KNIME Server Installation Guide to do so.

Reading from my local file system after update to KNIME Server 4.11+ is not possible

Starting with KNIME Analytics Platform version 4.2, which is the KNIME Executor version for the KNIME Server 4.11 we are, by default, not allowing access to the local file system on the KNIME Server via the new File Util nodes. You can enable this again as described in KNIME Server Admin Guide.

Please note that this only affects nodes that are part of the revised file handling framework.

The authentication field is empty

Please update the knime-tomcat.jar as described in the Application server update section. This must be done before restarting the KNIME Server.
