Licensing for Rational ClearCase and Rational ClearCase MultiSite

Both Rational Common Licensing and ClearCase® Atria licensing are supported for use with Rational® ClearCase .

You can use either Rational Common Licensing (powered by FLEXlm software) or ClearCase Atria licensing. During installation, you can only choose one: Rational Common Licensing or ClearCase Atria licensing. You can dynamically switch license modes after installation.

The benefit of using Rational Common Licensing is that you can have a single Rational License Key Server manage your Rational ClearCase, IBM® Rational ClearQuest®, and other IBM Rational product license keys using Rational Common Licensing.

IBM Rational License Key Center shows two types of license keys for IBM Rational ClearCase: "classic" Rational ClearCase keys and Rational ClearCase keys based on FLEXlm software. The term "classic" Rational ClearCase license keys refers to the ClearCase Atria licensing.

Note: IBM Rational ClearCase MultiSite requires both a IBM Rational ClearCase license key and a Rational ClearCase MultiSite license key. This licensing model is similar to IBM Rational ClearQuest MultiSite, as explained in Using Rational ClearQuest MultiSite license keys.
