License options in DWA
Licenses are acquired for each user session, but are managed on the server side rather than in the client process. The server acquires licenses from the license server when users connect. When users log off, the server releases the licenses. Users do not need direct access to the license server through any firewalls that might exist.
The IBM Common Licensing must be installed on your system. For information about the IBM Common Licensing, see IBM Common Licensing.
The licensing models differ between IBM Engineering Requirements Management DOORS (DOORS) and DWA. DOORS licensing is client-based and uses hostname, while DWA is server-based and uses username. Because the products use different licensing models, you cannot share DOORS licenses even if they are running on the same computer. For information about license usage and when it is required, see the following table.
Action | License requirement |
---|---|
Start and run the DWA server | No license is required |
Log in to DWA through the client | A license is required |
Another tool implements code directly against the OSLC RM domain to use it as a server API | A license is required |
Show DOORS data from an integrated product by using a delegated UI for selecting requirements or UI previews, such as compact rendering and rich hovers | A license is not required |
Use node-locked licenses on the DWA server | Not supported |
Link models and licensing
Two link models are used between products: back links and link discovery.The following products integrate with DOORS and use back links. When a user creates a link that requires an update to DOORS to add a back link, a license is required. The OSLC GET and PUT commands are used.
- IBM Engineering Workflow Management
- IBM Engineering Test Management
- DOORS
The following products integrate with DOORS and use link discovery. To determine traceability, you must authenticate to the user database of another tool, so a license is required. However, if a user creates a link, no DOORS data needs to change, so no license is required.
