Users can only receive a license if a license is available in the pool
A user who is assigned a floating CAL can only use the supported CAL functions if there is an available CAL in the pool. For example, if a server administrator purchases three floating Rational Team Concert™ - Developer CALs and assigns them to five users, then only three users can use the CALs at the same time. CAL usage starts when a user performs their first server operation that requires the CAL. A user holds the CAL until 2 hours (by default) after their last server operation or until the user explicitly logs out.
You can set up a Jazz™ Team Server application as a dedicated floating CAL server
You can simplify floating CAL usage administration and tracking by using a single server to manage all floating CALs in a multiple Jazz Team Server environment. Select a server to manage the floating CALs, such as an existing server that runs as a Jazz Server and floating CAL server. After installing floating CALs on that server, you can configure other Jazz servers to point to the floating CAL server. Then, those Jazz servers can assign and use the floating CALs.
If you have multiple Jazz Team Servers, floating licenses can move freely between multiple Jazz Team Server applications that are requesting licenses from a single floating CAL server.
When to install a separate Jazz Team Server as a dedicated floating CAL server
To determine whether to install a dedicated license server or to re-use an existing Jazz server as a floating CAL server, consider the following information:

A floating CAL server can also distribute Rational Common Licensing tokens
Another type of floating CAL, called the Rational Common Licensing Token Service, is an extension of the Jazz Team Server that allows token requests to be forwarded to a Rational License Key Server. When the Jazz Team Server requests a certain number of tokens, the extension checks out the tokens from a Rational License Key Server. This integration allows Jazz-based IBM Rational products and non-Jazz based products to share the same tokens. See Setting up the Rational Common Licensing token service keys for more information.

application:
Licenses enable capabilities for all applications that are registered with the same Jazz Team Server application. For example, if you check out a license that allows you to use the Change and Configuration Management (CCM) application, you will have the same capabilities in every CCM application that is registered with the Jazz Team Server; you won't need two licenses to access two CCM applications.
Although floating licenses can move freely between multiple Jazz Team Servers as they are requested, if you have multiple Jazz Team Server environments, you might need to check out multiple licenses to unlock capabilities on applications that are registered with different Jazz Team Server applications. For example, if you have one CCM application registered with a Jazz Team Server, and another CCM application that is registered with a different Jazz Team Server, to use both CCM applications at the same time you would need two licenses - one for each CCM application. Even if both Jazz Team Server applications use the same dedicated floating CAL server, if you simultaneously use two different applications that are registered with different Jazz Team Servers, you will check out two licenses.
License management is handled by each Jazz Team Server
If you use a dedicated floating CAL server, you will have to assign licenses to users separately on each individual Jazz Team Server. Every Jazz Team Server application manages the user information and license assignments for all applications that are registered with that Jazz Team Server.
