QPR supports also a Transient license type. Transient license agreement defines a fixed period of time for using the product. With QPR Product Activation Server Transient License Account there can be a fixed expiration date or a number of days the software can be used after activation. Definitions for transient license types:
•Transient License with fixed expiration date – Hard Date Expiration. License Expiration Date is defined in QPR Product Activation Server's license account. Organizations can activate and use the product(s) with Transient Product Activation Code until the expiration date. After expiration date the Organization must renew the License Agreement.
•Transient License with fixed expiration time – Soft Date Expiration. Number of License Expiration Days (0-9999) is defined in QPR Product Activation Server's license account. Organizations can activate and use the product(s) with Transient Product Activation Code for a fixed number of days after activation. After expiration date the Organization must reactivate the product with Transient Product Activation Code.
Transient license with 0 (zero) day soft expiration is a special case that can be used for example pay-per-use type of business models. Zero day soft expiration means in practice that the product must be reactivated every day it is used. QPR Activation Utility supports this model by providing a possibility to reactivate a transient license silently. Silent reactivation for transient license can be set easily by changing QPR_Shared.ini configuration file (see chapter Transient Product Activation).
Organization rents a QPR Product for 6 months. The calendar period is agreed to be June 1st 2003 – December 31st 2003. Transient License Account with December 31st 2003 as hard expiration date is created and the Organization gets a Product Activation Code for product activations. The Organization can activate the product freely with transient product activation code between June 1st 2003 and December 31st 2003. Product activation expires on December 31st 2003 and the software cannot be used on January 1st 2004.
Organization makes a pay-per-use agreement with an ASP provider for using QPR Products. Transient License Account with 0 (zero) day soft expiration days is created and the Organization gets a Product Activation Code for product activations. Every time the product is started, silent reactivation is done to QPR Product Activation Server. The ASP provider gets activation reports from QPR Software Plc. and charges the organization based on actual usage.
