Most Rational® ClearCase® applications
and commands (cleartool commands, for example,
or GUIs such as the Rational ClearCase Explorer)
require a license to run. Rational ClearCase can
use Rational Common Licensing,
which is based on the FLEXlm license management tool from GLOBEtrotter
Software, Inc., or ClearCase Licensing, a
proprietary licensing scheme.
The behavior of licenses (when they are required, how they are
granted, how long they are valid, and so on) is similar in both licensing
systems. However, the systems are separate, and each scheme has different
administrative requirements.
Note: After you reconfigure a Rational ClearCase host
to use a different licensing system, you must stop and restart Rational ClearCase on
that host.
