How to debug licensing problems
Make sure that the license server is actually running.
See [http://eranger3.ethz.ch/Ueberwachung/LIZENZ24h.html: ID License Server Status] to get an overview all license servers hosted by ID.
What licensing mechanism is used for your problematic software?
A lot of software you can order via IDES use a network licensing mechanism. That means that a client that wants to use some software first needs to ask the license server if there is a free license available. There are several software implementations for network licensing. The most prominent one is FLEXnet. If you ordered a license via IDES and the license email from IDES states that you have to enter some port and license server information during installation, the licensing system used is probably FLEXnet. An example is MATLAB.
FLEXnet license debugging
What you need:
- The name and port of the license server.
The lmutil command line tool.
Port and license server name
You will find these information in the email you got from IDES after ordering the software. If you did not order the software by yourself (e.g. if you work on a machine not managed by you), you might find that information
- through a menu entry of the application
- in the installation folder of the software
- in the registry (if you are running a Microsoft product)
- in an environment variable
This software is installed on any Linux workstation (tardis-whatever). So please just log in to on of these in order to debug FLEXnet licensing problems.
Usage of lmutil
If you run lmutil help it will print out a list of options. If you want to know the details of, e.g., the lmstat option, just run lmutil lmstat help. Here are some examples (just replace PORT and SERVER with the corresponding information for your software):
- lmutil lmstat -c PORT@SERVER -a
- lmutil lmstat -c PORT@SERVER -i
- lmutil lmstat -c PORT@SERVER -f
- lmutil lmdiag -c PORT@SERVER -n
