Manage Floating Licence Servers

The legacy licence manager allows you to check-in a licence to make it available again for other users.

While a licence is checked out, nobody else can use that licence. It may happen that a user has say CADFEKO open on his machine while he is on leave, or that the licence is urgently needed for another run and the user is not available to stop his run. The licence manager therefore allows checking in a licence so that it becomes available again. Click on the licence and from the right-click context menu, select Check in licence, or click on the licence and select Server > Check in licence from the main menu. For security reasons, this check in operation is allowed only for users with administrative privileges (Windows) or the root user (UNIX) or the user who has initially checked out this licence.

If a licence has been checked in manually, all running components using that licence will fail the next time they check the licence server. In the case of the solver components (RUNFEKO, PREFEKO, Feko, ADAPTFEKO and OPTFEKO) the error is fatal and the entire solution will be lost. The GUI components (CADFEKO, POSTFEKO and EDITFEKO) will close after giving the user an option to save the current model. It is preferred to only use this manual check-in feature when only GUI components are checked out for a particular licence, and if these GUI components cannot be closed directly.

In addition, the Server item on the main menu allows Shutdown and Reset. If multiple redundant floating licence servers are used, then both Reset and Shut down apply to all the running and active servers. For security reasons, both these operations are restricted to users with administrative privileges (Windows) or the root user (UNIX) or the user account under which the licence server is running. Generally, it should only be necessary to Reset the licence server when modifying the licence file (for example when obtaining a new licence file or when changing the TCP port).

Note: Resetting the licence server will check in all licences, so that all active user jobs will be terminated (similar to checking in individual licences).

Users should not need the Shutdown option unless the floating licence server executable needs to be updated with a newer one.

Note: Once the licence server has been shut down it must be restarted on the server itself, the licence manager cannot connect to the service if it is not running (for multiple redundant floating licence servers each must be restarted individually).
