3Chapter 4 - Commuter Licensing
One of the most useful advantages of the SentinelLM license management sys-
tem is that it provides commuter licensing, which allows you to temporarily use
a protected application on a portable computer that is not connected to the net-
work.
The most common use of commuter licensing is when a user of your network
needs to travel on business and wants to take along the protected application. If
the license code for that application has been defined by your vendor to allow
commuter licensing, the network user can check out an authorization to use the
application for the duration of the trip, and then check the authorization back in
on returning.
How Does Commuter Licensing Work?
To check out an authorization, the portable computer (for example, a laptop) on
which the application will be used must be attached to the network and have
access to a license server containing the license for that application. The applica-
tion must also be installed on that laptop. After checking out an authorization,
the user may disconnect the laptop from the network.
Restricting Commuter Licensing
Commuter licensing uses up the same license tokens as other types of licensing.
If you want to restrict the percentage of license tokens on a specific license
server that can be used by commuter licensing authorizations, use the -com
option when you start the license server. (See “Appendix A - Using Environment
Variables to Configure a License Server” on page 123 for details on license
