Using the three-server redundancy capability in FlexNet Publisher, all three license servers operate to form a triad. The license servers send periodic messages to each other to make sure that at least two servers are running and communicating. A quorum is formed when at least two of the three license servers are running and communicating with each other. For more information, see the FlexNet Administration Guide on the FlexNet license server installation and licensing page.
Teamwork Cloud and Magic Collaboration Studio versions earlier than 2024x Refresh1 do not support the redundant three-server configuration. |
In order to run a license server in a Three-Server Redundancy mode (Triad License Server), you must first obtain a license key suited for it.
The license key must contain 3 SERVER lines with hostnames and MAC addresses defined.
root.LicenseEngine started with redundant configuration - xxxxx@xxxxxxx, xxxxx@xxxxxxx, xxxxx@xxxxxxx. root.Quorum is starting up. root.Quorum is waiting |
Licenses will only be served when there are at least 2 license servers running.
If lmadmin was previously started with a different, single server license, there is additional action needed. By starting a single license server, it goes into a single license server mode, and thus won't accept Three-Server redundancy (Triad) license keys.
There are two options:
To do a clean installation of lmadmin, first, you need to remove the previous installation. Then you can proceed with the fresh installation (see Starting on a fresh installation of lmadmin).
Reconfigure the current lmadmin and change the license mode:
Steps to change server mode:
Type lmadmin -import <new_license_file> -force -configDir <config_dir>
This is an example (change the paths according to your machine): lmadmin -import "C:\Program Files\FlexNet Publisher 64-bit License Server Manager11_17\licenses\cameo\triadKey.txt" -force -configDir "C:\ProgramData\FLEXlm\lmadmin11_17\conf" |
After executing the command, in the cmd line you should see:
Configured new vendor daemon, cameo. |
root.LicenseEngine started with redundant configuration -xxxxx@xxxxxxx, xxxxx@xxxxxxx, xxxxx@xxxxxxx. root.Quorum is starting up. root.Quorum is waiting. |
