inform Inform the supervisor of license usage counts from external license managers |
...
qbupdateresource is used to inform the Supervisor of license usage counts from external license managers (FlexLM, RLM, MP, etc.). When Qube! competes for licenses or other resources with an "external entity", (be that users or another queuing system), the Qube! Supervisor can reconcile it's its internal license or resource usage counts with the values retrieved from that license manager.
The Qube! system administrator needs to write a script that runs on a periodic basis, queries the license server for the current usage, and if the license count has changed since the last time the script was run, calls qbupdateresources to inform the Supervisor of the new counts.

- you own 100 prman licenses
- Qube! is configured to allow up to 100 prman job instances to be running at any one time by defining license.prman=100 (see System-wide Wide Resource Tracking and License Resources).
All well and good, until end-users also start consuming prman licenses. Here's how this gets reconciled:
- Qube! is currently running 60 job instances that are consuming a prman license (via the job being submitted with a reservation of license.prman=1 - see Job Reservations)
- The scripts gets the count from the external licenser server, and finds that now there are actually 80 prman licenses in use according to the prman license server. The script calls:

–total flag behavior explained
The -total value you give it via the "qbupdateresource" command specifies the grand-total number of licenses, while the value you specify in the qb.conf file's supervisor_global_resources parameter refers to the total (maximum) number that the farm may use.
...
That's because the "outside" count has gone over its "reserved" amount of 20, and 10 bleed into the farm allocation.
