Normally, as jobs are dispatched and executed, the Supervisor continually updates the global resource counts to match. However, many sites subscribe to a single floating license server to control all licensed applications, not just the ones running on a compute farm. If those licenses are allocated to other processes not monitored by Qube!, the Supervisor runs the risk of dispatching a job where there are no licenses available for the application it will try to execute.
...
- The Supervisor must be configured with a license resource equal to the maximum license allocation to the compute farm.
- An external application must be developed that can monitor the license server and call qbupdateresource to update the Supervisor on a regular basis.

Here is an example of the license resource configuration of five mental ray licenses:
supervisor_global_resources = license.mentalray=5
and an example call to qbupdateresource to register that a total 5 licenses are installed, and 2 are currently in use:
% qbupdateresource –name license.mentalray -total 5 -used 2
