Enabling License Time-Outs

To take advantage of time-outs, you must specify the FLEXlm TIMEOUT option in a FLEXlm options file. A FLEXlm 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:

Create a FLEXlm options file. Using any text editor, create a text file named MLM.opt and put the file in the flexlm folder in your MATLAB installation folder. For example, you might create the file

D:\Applications\MATLAB71\Flexlm\MLM.opt

Add the FLEXlm TIMEOUT option to the file, using the following syntax:

```
TIMEOUT feature seconds
```

For feature, specify MATLAB. You cannot specify separate time-out values for individual MathWorks products, such as toolboxes.

For seconds, specify the amount of idle time you want to allow. The minimum value is four hours (14,400 seconds). If you specify a time-out value that is smaller, the minimum value is used. For example, to specify a five hour time-out, enter the following in your options file.
- ```
TIMEOUT MATLAB 18000
```

Note You can also use the FLEXlm TIMEOUTALL option to enable time-outs in your options file; however, this applies the time-out to all the products listed in the License File, which might include products from other vendors. The MathWorks recommends using the TIMEOUT option to set the time-out for MATLAB only.

Make sure the DAEMON line in your License File specifies the location of your options file. Open your License File in a text editor and add the options= syntax to the DAEMON line. For example, your DAEMON line might look like the following:

DAEMON MLM "D:\Applications\MATLAB71\flexlm\mlm.exe" 
                options=D:\Applications\MATLAB71\flexlm\mlm.opt

Stop the license manager and then restart it. Whenever you change the License File, or change the time-out value in the options file, you must restart the license manager. You can use the LMTOOLS utility to start the license manager. Click the Start Server button on the Start/Stop/Reread panel.
