Introduction
Centralised tracker licencing licensing is a new feature available in Sea360® and Witness ClearWay™ and AdvanceGuard® since from V4.8 and above. This significantly simplifies the process of licensing trackers and also removes any licencing licensing considerations when swapping radar in and out on a site. The primary difference compared to the older system is that the tracker software licence is no longer tied to any single item of hardware, instead the licence is tied to the site. This enables us to install the site licence on as many radar or servers as required and as long as the total number of active radar does exceed the licence count for the site then everything will be automatically authorised.
In addition there is a central licence that sits on one or both of the primary servers and this enforces the site limit for concurrent, active trackers. These central licences are tied to the hardware to ensure they remain unique to their designated site.

You will need to enable the feature in System Settings. Please refer to this documentation: https://navtechradar.atlassian.net/wiki/spaces/TUN/pages/206504312/System+Settings#Central-Tracker-Licensing. |
| Note |
|---|
For central licensing to work correctly the entire system has to be time synchronised, when using onboard tracking this requires that the radars have been configured with an NTP source. |
| Note |
|---|
Centralised licensing will not work on Witness™ versions older than V4.8. (e.g. Centralised licence will not work on V4.7) |

The definition of an active radar is one that is powered, connected to the Witness Witness™ software and has been allocated a software tracker. Only an active radar can generate real-time target data. A non-active radar is one that is not part of a live system. For example a radar which is being stored offsite in case a rapid replacement is required, is a non-active radar.

Licensing Components
There are two tracker licencing licensing components, both of which are deployed as part of the central Witness Witness™ licence file:
Management Server Licence
This is the central part of the site licence. This component contains the tracker count and controls how many concurrent trackers can be deployed on the site. This component is linked to the hardware on which the Management Server is running using the MAC / Physical address of the active network adapter.
| Info |
|---|
Note that each Each Management Server must have its own Witness Witness™ licence file, so if using a fully redundant setup with two Management SeversServers, both must have access to Witness Witness™ licence with the embedded central tracking licence. Note that each Witness Each Witness™ licence file will need its own version of the Management Server Licence component that is the linked to the relevant MAC address of its host hardware server. |
Tracker Licence
The tracker licence component is distributed to all radar or servers where the tracking software will run. This is just a single component and it is shared by all trackers. If additional, spare radar are available for a site then these will also require the same tracker licence component. This allows radar to be swapped as required and as long as the total number of active radar has not changed then no further action is required.
Deploying the Licences
Both the Management Server Licence and the Tracker Licence components are stored inside the Witness Witness™ licence file. Once this file is loaded by the Management Server on system start-up all the components are automatically deployed to where they are needed.
No further action is required to licence the trackers.

Requesting a Licence
In order to create the Witness Witness™ licence, Navtech must know the total number of active radar that will be deployed on the site. In addition we must know the MAC address of one or both servers which will be hosting the Witness Witness™ Management Server application.
...
When requesting a licence from Navtech you will need to provide us the following information so we can provide the correct tracker licencing licensing components:
How many active radar are required
The MAC / Physical address of the Primary Management Server hardware
The MAC / Physical address of the Secondary Management Server hardware, if using a fully redundant configuration
Examples
Example 1
The customer is deploying 8 active radar all of the same model and is using only a single Management Server
...
A single Management Server Licence with a tracker limit of 8x radar.
A single Tracker Licence (for use on all radar).
Navtech will require the MAC / Physical address of the server that is hosting the Management Server app.
Example 2
The customer is deploying 10 active radar, 4 of one model, 6 of another, and has also purchased a spare radar for rapid replacement. The customer is not using redundancy.
...
A single Management Server Licence with a tracker limit of 10x radar.
A single Tracker Licence (for use on all radar, including the spare).
The models make no difference to the tracker licence
No additional licence is required for the hot spare but it can have the Tracker Licence installed
Navtech will require the MAC / Physical address of the server that is hosting the Management Server app.
Example 3
The customer is deploying 50 active radar, has two spares and is also using a fully redundant setup
...
Two (2x) Management Server Licences each with a tracker limit of 50x radar.
A single Tracker Licence (for use on all radar, including the spares).
No additional licence is required for the hot spares but they can have the Tracker Licence installed
Navtech will require the MAC / Physical address of both servers that are hosting the primary and secondary Management Server apps.
Adding Additional Radar
If the customer needs to expand the site by adding more active radar, then the software will require an updated Witness Witness™ licence. The central Management Server Licence component needs to be updated with the new active tracker limit.
...
| Info |
|---|
If using a redundant setup you will need to replace the Witness Witness™ licence containing the new Management Server component on both servers hosting the Management Server app. |
