### Additive, Exclusive, and Aggregate License Codes

License codes are either additive or exclusive or aggregate.

An exclusive license code completely replaces other licenses, regardless of whether they are additive or exclusive.

Two additive licenses add up to become one additive license with one common start date, end date and limits (hard and soft).

Whereas, in the case of aggregate licenses, the individual start date and end date remain valid and the limits (hard and soft) congregate only during the overlapping license tenure.

Additive licenses are a better choice when a permanent hike in license demand pattern is inevitable and more number of licenses are required round the clock. Aggregate licenses are more like top-up licenses and make best choice for short term hikes in license demand.

Redundant license License Managers handle additive license codes slightly differently. A redundant License Manager 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.
