3 License Management
Experiencing a License Time-Out
When time-out is enabled, if you open a MATLAB session, and then leave it
inactive for more than 4 hours, when you return, you vriU find MATLAB still
open on your desktop. However, you will see the following message displayed
in the Command Window:
Your MATLAB session has timed out. All license keys have been
returned.
The time-out is also recorded in the Ucense manager log file, as follows:
Idle session. Returning keys for <user>@<machine>
(For more information, see "Viewing the License Manager Log File" on page
3-17.)
Reacquiring License Keys After a Time-Out
To resume a timed-out MATLAB session, just start using MATLAB again. If a
license key is available, MATLAB checks it out automatically. Likewise, as
you use the toolboxes and other products that you had checked out, MATLAB
obtains license keys for these products as well.
If a license key is not available, MATLAB periodically attempts to check out a
license, issuing warning messages. After 10 wamings, if a license key is still
not available, MATLAB saves the workspace and exits.
Note If you retum to a timed-out SimuUnk® session, you cannot run or
modify a currently open model. These menu options are disabled until a
Simulink license key becomes available. You can only save a model in a
timed-out Simulink session.
