Configuring the License Server - Basics

Additive and Exclusive License Codes

License codes are either additive or exclusive.

An additive license code adds users to an existing license code and saves you from recreating licenses while an exclusive license code completely replaces the old license with a new recreated license.

There can be multiple exclusive license codes per product in the license file. Only the last exclusive license code added to the file is used by the license server, if exclusive licenses are used. All other license codes, additive or exclusive, are ignored by the license server.

There can also be multiple additive license codes per product in the license file. Unless there are exclusive license codes for the same feature/version, then each additive license simply adds to the permitted uses defined by previous additive license codes. For example:

Let’s say there is a product with a feature name 77 and version 5.0.

There may be two additive license codes for 77 5.0. One of these license codes may authorize five concurrent users. The other may authorize two concurrent users.

A license server provided with both license codes will authorize up to seven concurrent users of the application that uses feature name 77 and version 5.0.

Additive license codes are generally used to increase the number of available licenses or number of client computers or to change the expiration date. Your vendor can tell you exactly what parameters have been changed by the additive license codes given to you.

Note: Redundant license servers handle additive license codes slightly differently. A redundant license server may service both redundant and non-redundant license codes. A redundant license code that is additive will always override any exclusive or additive non-redundant license codes for the same application feature and version.

You may receive a permanent, non-redundant or redundant license code that replaces a temporary, trial license. Additive permanent licenses always replace trial licenses even if the trial license has not yet expired.
