We got many questions on the 4D Forum on how licenses work using 4D for Mobile, and this is an excellent time to remind you of the process through this blog post that answers the most frequently asked questions.
4D for mobile usage is covered by your Client licenses.
Basically, you can connect as many mobile devices as are available licenses. And the great news: if you already have extra licenses, you don’t have to buy new ones and continue using your 4D applications as before!
Example: if you have a 4D Server plus an expansion for two clients (in total, four clients), you can use up to four mobile devices.
Do not hesitate to contact your sales representative if you have specific needs that would require a significant number of licenses!
deal with device sessions
No need to worry about session management. To get the best user experience for server administrators and for mobile users, when needed 4D takes care of disconnecting mobiles and removing sessions, if you have not purchased enough licences!
And if you want to visualise mobile sessions and manage them manually you can still use the session management tool.
What about action forms and pending actions
You will never lose your work :
- Regarding pending action, if your session is unavailable server side, you will be logged out due to the insufficient number of licenses. This doesn’t mean that you are going to lose your work! If you log in again with the same email, you will retrieve all your pending actions. And those will be executed when the network becomes available.
- Same way with action forms. Imagine that you are validating an action form, but you have been logged out. This action will be put in a pending state.
As you can see, this way to deal with mobile sessions will guarantee an excellent experience for server administrators and mobile users!
