Thanks Michael, yes i have gone through but the licenses are remote license and it will be used by outside as well not only in slurm. so basically i am interested to know how we can update the database dynamically to get the exact value at that point of time. i mean query the license server and update the database accordingly. does slurm automatically updated the value based on usage?
