License descriptions

As a purchaser of an IBM® Rational® software product, you can choose from four types of product licenses:

The best choice for your organization depends upon how many people use the product, how often they require access, and how you prefer to purchase software.

Authorized User licenses

An IBM Rational Authorized User license authorizes an individual to use a Rational software product. You must obtain an Authorized User license for each individual user who accesses the product in any manner. An Authorized User license cannot be reassigned unless you replace the original assignee on a long-term or permanent basis.

For example, if you purchase one Authorized User license, you can assign that license to one individual who can use the Rational software product exclusively. The Authorized User license does not authorize a second individual to use that product at any time, even if the licensed individual is not using the product.
Note: If you purchase IBM Rational Performance Tester as part of IBM Rational Test Workbench, you do not require runtime licenses such as protocol key to run a schedule.
An IBM Rational Authorized User Fixed Term License (FTL) authorizes an individual to use a Rational software product for a specific length of time (the term). Purchasers must obtain an Authorized User FTL for each individual user who accesses the product in any manner. An Authorized User FTL cannot be reassigned unless the purchaser replaces the original assignee on a long-term or permanent basis.
Note: When you purchase an Authorized User FTL under the IBM Passport Advantage® Express® program, IBM automatically extends the license term for an additional year at the prevailing price unless you notify IBM before the license expires that you do not want an extension. The subsequent FTL term starts when the initial FTL term expires. The price for this subsequent term is currently 80% of the initial FTL price, but is subject to change.

Floating licenses

An IBM Rational Floating license is a license for a single software product that can be shared among multiple team members; however, the total number of concurrent users cannot exceed the number of floating licenses you purchase. For example, if you purchase one floating license for a Rational software product, any user in your organization can use the product at any given time. Another person who wants to access the product must wait until the current user logs off.

To use floating licenses, you must obtain floating license keys and install them on a Rational License Server. The server responds to user requests for access to the license keys; the server grants access to the number of concurrent users that equals the number of licenses the organization purchased.

Floating license enforcement provides these benefits:
  • License compliance enforcement throughout the organization
  • Fewer license purchases
  • License keys served for IBM Rational Team Unifying and IBM Rational Software Delivery Platform desktop products from the same license server
  • Some versions of Rational products require an upgraded version of the Rational License Server. See this support article for license upgrade information:

Token licenses

The token-based license model means that you can buy a certain number of token licenses. If you use a Rational tool that checks out a feature that is token-based, the feature line in the license file specifies the number of tokens that are checked out. Token-based licenses can only be used with floating licenses. They cannot be used for authorized user license. For more details about token licensing, contact your local IBM marketing representative.

Processor value unit (PVU) licensing

Processor value unit (PVU) licensing is for providing you pricing structures that are responsive to both the type and number of processors that are available to installed products.

Entitlements can be full capacity or subcapacity. Under the processor value unit licensing structure, you license software based on the number of value units assigned to each processor core. For example, processor type A is assigned 80 value units and processor type B is assigned 100 value units. If you license a product to run on two type A processors, you must acquire an entitlement for 160 value units. If the product is to run on two type B processors, the required entitlement is 200 value units.

The processor value units table, which assigns a number of value units to each supported processor type, is regularly updated to provide for the introduction of new processor technologies. Agents retrieve information about the number and type of processor on the monitored computer or partition and the table is used to determine the level of license use in terms of processor value units.
