Troubleshooting Qlik DataTransfer

Qlik DataTransfer is not running and the log shows there was an error executing a PowerShell script command

Qlik DataTransfer is not running. The log shows the following error message:

Possible cause  

ExecutionPolicy is disabled or restricted for that user.

Proposed action  

Enable or give permissions to execute PowerShell script by giving the user the RemoteSigned execution policy. You can do this from PowerShell in administrator mode by running PS C:\> Set-ExecutionPolicy RemoteSigned in PowerShell and selecting Y. You can contact your system administrator to do the same.

I am experiencing high CPU usage from Qlik DataTransfer

Qlik DataTransfer is using a high amount of CPU.

Possible cause  

There may be a shared folder configured as a data folder, Qlik DataTransfer may be polling on the folder, which uses more CPU.

Proposed action  

Do one of the following:

• To stop polling, navigate to the services.conf file, located in %Program Files%\Qlik\DataTransfer. Open the file and remove --usePolling. This will discontinue watching a shared folder after the service is restarted.

• To poll at a greater interval, you can change the default polling interval from 100 milliseconds to a greater value, such as 3000 milliseconds. Navigate to the services.conf file, located in %Program Files%\Qlik\DataTransfer. Open the file and add --pollingInterval after --usePolling. Set the polling interval in milliseconds, for example --pollingInterval 3000.

Qlik DataTransfer shows a blank page when installed on secondary nodes of Qlik Sense Enterprise on Windows cluster

Qlik DataTransfer has a blank page. Qlik Sense certificates are not exportable in a developer node.

Possible cause  

Qlik DataTransfer was not installed on the central node.

Proposed action  

Follow these step:

1. Perform the regular installation steps.

2. In Windows Services, stop the Qlik DataTransfer service.

3. Navigate to C:\ProgramData\Qlik\DataTransfer\DataUpload\certificate and delete the certificates in the folder.

4. In the Windows Certificate Store, delete the following certificates, if available:

   • Local Computer > Personal > QdtClient

   • Local Computer > Trusted Root Certification Authority > <hostname.domain> or <hostname>

   • Current User > Personal > QdtClient

Alternatively, you can run Remove-Certificate.ps1 (C:\Program Files\Qlik\DataTransfer\DataUploadService\install-utils) in PowerShell as the administrator.

5. Navigate to C:\Program Files\Qlik\DataTransfer\DataUploadService\install-utils.

6. Copy Configure-Service.ps1.

7. Log in to central node using Qlik Sense Enterprise on Windows service user account.

8. Paste this file to central node at any location.

9. Run Configure-Service.ps1 in PowerShell as the Qlik Sense services user.

1. For the first input dataTransferCertificatePath, enter any folder location on the machine. This will export certificates to this location.

2. For the second input qsefwPresent, enter Yes.

10. Navigate to location where certificates are exported and confirm the following files are present:

    1. root.pfx

    2. client.pfx

    3. server.pfx

11. Copy all three certificates.

12. Go to the Qlik DataTransfer installed machine.

13. Navigate to C:\ProgramData\Qlik\DataTransfer\DataUpload\certificate and paste all certificates.

14. Restart the Qlik DataTransfer service.
