Installing Release 12.1 on UNIX Workstations (MATLAB Installation Guide for Unix) MATLAB Installation Guide for Unix     Setting Up User-Based Licensing If you have a user-based license, you must set up a FLEXlm license options file after your installation is complete. You use the license options file to specify the list of users who can use each product. The INCREMENT lines in a user-based License File contain the word USER_BASED. User-based licenses let you control who can check out license keys for products. To set up a user-based license, you must: Check that the DAEMON line in your processed License File ($MATLAB/etc/license.dat) includes the name of an options file as its fourth argument. See Creating a Local License Options File for an example. For user-based licenses, the installer creates a default license options file, $MATLAB/etc/MLM.opt, if there isn't already an existing options file. If you are adding a product to an installation with an existing options file, you can use that options file to set up user-based licensing. An options file is a simple text file, not encrypted, that can have any name, as long as the DAEMON line points to the correct one. Edit the license options file to make sure the correct users are listed. When the installer creates a default license options file, it gives access to only the user that performed the installation. If you want to change this user name or add more users, you must edit the license options file. See "Creating a Local License Options File" on page 2-10 for information about editing a license options file.  Configuring MATLAB Products Mounting Your CD-ROM Drive
