3 License Management
Using Time-Outs to Free Idle License Keys
Note You can only use time-outs with concurrent licenses.
If you have a concurrent license, you can use the FLEXnet time-out option to
automatically retum idle license keys at your site. With license time-outs, the
license manager automatically frees license keys that sit idle for a specified
period of time, retuming them to the pool of available license keys.
For example, when you start MATLAB and other products, such as toolboxes,
you check out license keys for these products. If you go home without exiting
your MATLAB session, these licenses remain checked out and are not
available to other users. With time-out enabled, after your licenses sit idle
for a specified period of time, the license manager releases the license keys
for all the products you had been using and these keys become available to
other users.
For more information about time-outs, see the following sections:
• "Enabling License Time-Outs" on page 3-18
• "Experiencing a License Time-Out" on page 3-20
• "Reacquiring License Keys After a Time-Out" on page 3-20
Enabling License Time-Outs
To take advantage of time-outs, you must specify the FLEXnet TIMEOUT option
in a FLEXnet options file. A FLEXnet options file is a text file that contains
license manager options statements, such as INCLUDE, EXCLUDE, and GROUP
statements.
To enable time-outs, follow these instructions:
1 Create a FLEXnet options file, if one does not already exist, using any text
editor. Name the options file MLM.opt and put the file in the flexim folder
in your MATLAB installation folder. For example, you might create the file
C:\Program Files\MATLAB\flexlm\MLM.opt
