Prerequisites

NovaSeq 6000 Integration v3.6.0 has the following prerequisites:

Prerequisite 1: Clarity LIMS v6.2 and above

This integration requires Clarity LIMS v6.2 and above and uses the Clarity LIMS Secret Utility. The Secret Utility is installed and configured by the installation tooling for Clarity LIMS v6.2 and above. No additional configuration is required.

For more information on Secret Utility configuration, refer to the Clarity LIMS (Clarity & LabLink Reference Guide) documentation.

Prerequisite 2: Illumina Preset Protocols (IPP) v2.6

The integration package depends on the configuration provided in Illumina Protocols (IPP) v2.6.

The installation procedure provided in this document includes steps that install the following IPP configurations on the server used for the NovaSeq 6000 integration installation:

• NovaSeq configuration

• Library Prep Validation configuration (optional, but recommended)

For details on IPP v2.6 installation and configuration, refer to the Illumina Preset Protocols documentation.

Prerequisite 3: Proxy Update

The Illumina cloud hosted installation configures an additional include directive for /etc/httpd/conf.d/clarity.conf in the proxy configuration. Additional proxy configuration files for the Sequencer API service are expected to be placed in the /etc/httpd/conf.d/clarity folder.

Sequencer API RPM Installation Components

NovaSeq Integration v3.6.0 is distributed as the BaseSpaceLIMS-sequencer-api RPM package. This package must be installed on the Clarity LIMS server.

The BaseSpaceLIMS-sequencer-api RPM installs the following files and scripts:

• Sequencer API WAR file

• application.yml configuration file

• configure_sequencer_api_proxy.sh configuration script

• configure_sequencer_api_env.sh configuration script

• configure_sequencer_api_application.sh configuration script

Sequencer API WAR

The RPM installs the Sequencer API WAR file into the same Tomcat container as Clarity LIMS. The WAR file is at /opt/gls/clarity/tomcat/current/webapps/Illumina#Sequencer#v2##2.6.0.0.war. The version number can differ.

The WAR file is deployed automatically when Clarity LIMS launches. Because the RPM installs a new WAR file, Clarity LIMS is automatically stopped during installation of the RPM. Restart Clarity LIMS before installing the NovaSeq and Library Prep Validation workflow configuration from the IPP.

Configuration File

The application.yml configuration file is installed at /opt/gls/clarity/extensions/sequencer-api/application.yml. As part of the installation process, the file is configured with one of the configuration scripts.

For a complete list of all properties included in the application.yml file, refer to NovaSeq 6000 Integration v3.6.0 Configuration.

Configuration Scripts

The scripts in the following table are installed at the /opt/gls/clarity/config/ folder. During installation, the RPM runs these scripts as they are needed.

Script Name	User	Description
configure_sequencer_api_proxy.sh	root	Adds configuration to the proxy to allow communication with the Sequencer API after Tomcat has been started. Run this script in the following scenarios: When the Sequencer API is first installed. When reconfiguring the Clarity LIMS proxy. This process happens until a version of Clarity LIMS that includes the necessary configuration files from /etc/httpd/clarity/.conf* is available. ℹ️ Not required for Illumina cloud hosted installations.
configure_sequencer_api_env.sh	root	Adds Secret Management setting into the Clarity LIMS Tomcat configuration.
configure_sequencer_api_application.sh	glsjboss	Configures the installed application.yml file. Sets the Clarity LIMS URL and the key to use when signing access tokens. ⚠️ Run this script when the Sequencer API is first installed. If you run the script multiple times, the script reconfigures each setting to its default. The only exception is the signing key. For this setting, you are asked if you want a reset. If the reset is done, all previously issued tokens are no longer valid.

Installation Steps

If running the sequencing service and Automation Worker on the same instance, the instance must also be running a compatible version of Oracle Linux. For compatibility, refer to NovaSeq 6000 Integration v3.6.0 Release Notes.
