Using FLEXlm License Management Utilities

FLEXlm provides license management utilities that you can use to monitor the license manager. These utilities are available at the command line or through a graphical user interface.

Using the lmutil Command

The lmutil command, available in the $MATLAB\flexlm folder, provides access to all the FLEXlm license management utilities. To view a list of all the capabilities of the lmutil.exe utility, open a Command Prompt window, go to the $MATLAB\flexlm folder and type

```
lmutil
```

Note You must run the lmutil function on the system on which the license manager is running.

The following table lists the names of the most useful tools available through lmutil. For more detailed information, see the FLEXlm End User Manual, included in PDF format in your MATLAB installation ($MATLAB\flexlm\enduser.pdf).

Utility
Description

lmdiag
Diagnose license checkout problems.

lmdown
Shut down all license daemons (both lmgrd and all vendor daemons) on the license server node.

lmhostid
Report the host ID of a system.

lmreread
Make the license manager daemon reread the License File and start any new vendor daemons.

lmstat
Display the status of all network licensing activities.

lmswitchr
Switch the report log file.

lmver
Determine the FLEXlm version of a library or binary file.

Utility	Description
`lmdiag`	Diagnose license checkout problems.
`lmdown`	Shut down all license daemons (both `lmgrd` and all vendor daemons) on the license server node.
`lmhostid`	Report the host ID of a system.
`lmreread`	Make the license manager daemon reread the License File and start any new vendor daemons.
`lmstat`	Display the status of all network licensing activities.
`lmswitchr`	Switch the report log file.
`lmver`	Determine the FLEXlm version of a library or binary file.

For example, to view the current status of the license manager, open a DOS command prompt window and enter the lmutil command, specifying the name of the lmstat utility. The example uses the -a option to get a verbose listing of available licenses and the -c option to specify the location of the License File to use. You must specify the -c option with every tool invoked through lmutil.exe.

lmutil lmstat -a -c C:\matlabr14\flexlm\license.dat

The utility returns the following information about the current license manager status.

Using the FLEXlm Utilities Graphical User Interface

FLEXlm provides a graphical user interface (GUI), called LMTOOLS, to its license management utilities. The GUI provides access to the same set of tools as the lmutil command and displays the results returned in an integrated display window.

For example, to use LMTOOLS to monitor the status of network license activity, perform this procedure:

Start LMTOOLS by double-clicking the lmtools.exe file in the $MATLAB\flexlm folder.
Click the Server Status tab.
Click the Perform Status Enquiry button. LMTOOLS displays the same information as if you had entered the command lmutil lmstat -a.
