Activating a System-Specific License
This guide provides step-to-step instructions for activating or renewing a TigerGraph license, by generating and installing a license key unique to that TigerGraph system. This document applies to both non-distributed and distributed systems. In this document, a cluster acting cooperatively as one TigerGraph database is considered one system.
A valid license key activates the TigerGraph system for normal operation. A license key has a built-in expiration date and is valid on only one system. Some license keys may apply other restrictions, depending on your contract. Without a valid license key, a TigerGraph system can perform certain administration functions, but database operations will not work.
To activate a new license, a user first configures their TigerGraph system. The user then collects the fingerprint of theTigerGraph system (so-called license seed) using a TigerGraph-provided utility program. Then the collected materials are sent to TigerGraph or an authorized agent via email or web form. TigerGraph certifies the license based on the collected materials and sends a license key back to the user. The user then installs the license key on their system using another TigerGraph command. A new license key (e.g., one with a later expiration) can be installed on a live system that already has a valid license; the installation process does not disrupt database operations.
Note: Before beginning the license activation process, the TigerGraph package must be installed on each server, and the TigerGraph system must be configured with gadmin.
Collect the fingerprint of the whole TigerGraph system using the command tg_ lic_seed , which can be executed on any machine in the system. The command tg_lic_seed packs all the collected data into a local file (named tigergraph_seed). When tg_lic_seed has completed successfully, it outputs the path of the collected data to the console.
Collect Fingerprint of TigerGraph System
seed file is ready at /home/tigergraph/tigergraph/tigergraph_seed
Send the tigergraph_seed file to TigerGraph
, either through our license activation web portal (preferred) or by email to
If using email, please include the following information:
- Company/Organization name
- Contract number . If you do not know you contract number, please contact your sales representative or email@example.com.
- If the contract and license seed are in good order, a new license key file will be certificated and sent back to you.
- Copy the license key file to a directory on the TigerGraph system where the TigerGraph linux user has r ead permission .
To install the license key, run command tg_ lic_install , specifying the path to the license key file.
Usage: tg_lic_install <license_path>
If installation is completed successfully, the message "install license successfully" will be displayed in the console. Otherwise, another message "failed to install license" will be displayed.
Checking License Information
After a license key has been installed successfully on a TigerGraph system, the information of the installed license is available via the following REST API:

$ curl -X GET "localhost:9000/showlicenseinfo"
