Upload a License

This article explains how to upload a license to an Exasol database.

All Exasol deployments start with a license that allows you to load 10 GiB of raw data for testing purposes. For larger data sizes, you must upload a license to the database.

Prerequisites

  • Exasol must be installed.

  • You must have a valid Exasol license file.

Exasol 7.1 licenses are not valid in later versions of Exasol because of differences in the license format. For information about how to obtain a valid license, create a support case.

Procedure - ConfD

The following examples use ConfD through the command-line tool confd_client, which is available on all database nodes. You can also access ConfD through XML-RPC in your own Python programs. For more information, see ConfD.

  1. Download the license file to a directory on your local machine.

  2. To upload the contents of the license file to COS, use the cat Linux command and the ConfD job license_upload.

    Copy 
    cat <license_name>.exasol_license | c4 connect -s cos -i <play_id> -- confd_client license_upload license: '\""{< -}\""'

    Replace <license_name> with the name of the license file and <play_id> with the ID of the deployment. To find the ID of the deployment, use c4 ps.

    Example:
    Copy 
    cat 1234567890.exasol_license | c4 connect -s cos -i c3275f84 -- confd_client license_upload license: '\""{< -}\""'

When the license has been successfully uploaded to COS it is automatically applied after a few minutes.

The server may in some cases respond with an error message even if the upload was successful. To verify that the license was correctly uploaded, use the ConfD job license_info. For more information, see Check License.
