MATLAB: Do I receive License Manager Error -38

MATLAB

License Manager Error-38: "User/host on EXCLUDE list for feature"

The user/host/display has been excluded from this feature by an end-user's daemon option file.

Best Answer

This error indicates that either the username, hostname, or display is being prevented from using a product due to an EXCLUDE line in an options file. Options files are used by license administrators to control access to software licenses.

For instance, the following line in the options file will prevent anyone with the username 'jdoe' from accessing MATLAB:

 EXCLUDE MATLAB USER jdoe

In order to resolve this error, you will need to be removed from the EXCLUDE list. Contact your License Administrator to have this change completed.

This usually indicates that you are using a File Installation Key for an Individual or Designated Computer license instead of a Network Concurrent or Network Named User license. To get a new File Installation Key:

Go to the MathWorks License Center.
Click the Network Concurrent or Network Named User license from the list of licenses.
Click the "Install and Activate" tab.
Click "Get File Installation Key."

On Network Concurrent or Network Named User licenses, this button will only be visible to license administrators. If you do not see this button on your Network Concurrent or Network Named User license, click the "Contact Administrators" tab to see your license administrator's contact information.

This error message indicates that the license administrator has reserved all the licenses of the product you are trying to use for other users. In order to use the toolbox, the license administrator will have to configure the network license manager to free up a reserved license or add you to the list of allowed users/computers.

NOTE: The change is made in the options file on the network license manager. This change must be made on the license server machine in order to take effect.

To make the change, the options file (generally MLM.opt) must be edited. The options file that the network license manager uses is specified within the DAEMON line of the license file on the license manager. For example:

DAEMON MLM "C:\Program Files\MATLAB\R2010b\etc\win32\mlm.exe" \
     options="C:\Program Files\MATLAB\R2010b\etc\win32\mlm.opt"

For more information about where the options file, see the related solution: 1-1936F - "Is there a way to administer FLEXnet based licenses? How do I create an Options file?"

Here is an example options file where MATLAB licenses are reserved for the group "matlab_users":

GROUP matlab_users user1 user2 user3 user4 user5 user6 user7 user8
RESERVE 5 MATLAB GROUP matlab_users

Here is an example options file where the MATLAB licenses are reserved for specific computers called "matlab_computers"

HOST_GROUP matlab_computers host1 host2 host3 host4
RESERVE 5 MATLAB HOST_GROUP matlab_users

To resolve this issue either your username or hostname of the computer will need to be added to the GROUP or HOST_GROUP, depending upon which option is used. For the GROUP option, add the desired username to the end of the list. For the HOST_GROUP option, add the hostname of the computer to the HOST_GROUP line. Alternatively, you can resolve this issue by decreasing the number of licenses reserved. In the example above this can be done by changing "5" to "4" on the RESERVE line.

Once the appropriate changes have been made and the network license manager has been restarted, you should have access to the desired license.
