Reserve a License

#Security #Access control #InterSystems IRIS

Can a license be reserved for a specific user or group of users? So if I have 20 available licenses, only allow other users to use 19 of them while keeping one open for this specific user?

You can check how many license units available with this method $SYSTEM.License.LUAvailable()

And next depends on the kind of application, you develop. If it's some web application, and you have to achieve it for web session, I would try using %CSP.SessionEvents with OnLogin event, check how many license units are available and who is logging in, and decide to decline the login.

If you need it for some else ways of connections, I think the best place would be ZAUTHENTICATE.
