Change the Clarity LIMS Hostname

The core Clarity LIMS product includes the rename_claritylims_hostname.sh script, which allows you to change the hostname to which Clarity LIMS responds.

Prerequisites & considerations

Prerequisites

• Clarity LIMS must be fully installed and configured. If it is not, the script instructs you to complete the installation.

• The script stops all Clarity LIMS services. Make sure that all automation jobs are complete.

• If you are not using a wild card SSL Certificate, purchase a certificate for the new hostname.

• Update the hostname returned by the operating system to match the new name.

  Refer to Pre-script steps for more information.

• Running the renaming script requires root access.

Considerations

• The script does not update the Automation Worker installation. After you have completed the renaming steps, you must reconfigure all local and remote Automation Workers.

• You might need to reconfigure additional services, such as the Reporting and Sequencing services.

We recommend that you back up the database before performing the following renaming steps.

Settings changed

The following table lists the settings changed by the rename_claritylims_hostname.sh script.

Property	Global	Description	Location
namingProviderHost	Yes	Configures appropriate endpoint for the Automation Worker	/opt/gls/clarity/tomcat/current/lib/ activity-management-ui-config.groovy
api.uri	Per tenant setting	Base URI used by integrations for API calls	Property Table
ftp.host	Per tenant setting	Location of FTP host for this tenant*	Property Table
ServerName	Per tenant setting	Server name reference in lookup database	Lookup Database

*The ftp.host is only updated if it matches the previous IP address/hostname. This intended behavior accounts for the scenario in which the ftp host is on a different server.

Changing the LIMS hostname

Pre-script steps

1. Change the internal hostname

   Before running the rename_claritylims_hostname.sh script, change the internal hostname for the instance - that is, /etc/hosts and related areas. There is no need to change any other LIMS-related components.

   The new internal hostname will be used in the renaming process.

   • To verify the internal hostname, use the following command:

     hostname -f

     NOTE: If the hostname command does not return the correct new name, consult with your IT department to correct the name.

2. Verify SSL Certificate path:

   The script may prompt you for the SSL Certificate path. Be sure to have that ready.

Running the script

1. Use the following command to change to the root user:

   sudo su -

2. Navigate to the /opt/gls/clarity/config directory.

3. Run the rename_claritylims_hostname.sh script:bash rename_claritylims_hostname.sh

4. If prompted for your SSL Certificate path, enter this information.

5. The script prompts you to confirm that you have changed the internal hostname.

   • If you enter no, you will be prompted to manually change the hostname (output shown below).

     [root@qalocal config]# bash rename_claritylims_hostname.sh
     Does your internal hostname match the new Clarity server hostname?: n
     Please change your internal hostname to match the hostname you are passing to this script to ensure Clarity can connect to it.
      Do not change any Clarity related components.

   • If you enter yes, the script proceeds to modify Clarity LIMS-related components to use the new hostname.

6. When the renaming is complete, the script prompts you to restart Clarity LIMS by running the run_clarity.sh script:

   /opt/gls/clarity/bin/run_clarity.sh start

7. When all Clarity LIMS services have restarted, make sure that the hostname has been changed successfully. Complete the following steps:

   • Connect to all system components.

   • Log in and test the LIMS user interface in your web browser.
