Manage sessions of web apps

20 views (last 30 days)
I recently deployed a web app and asked some colleagues to try it. It seems that they often get the "All available sessions are in use. Try again at a later time" error, although I wouldn't have expected anything close to 32 concurrent sessions. Are there ways to:
  1. See and manage all active sessions? Something like a session manager.
  2. Force sessions to timeout even when the user is inactive on the app, without having to close the browser, get the computer to sleep mode, etc?

I'm experiencing a similar issue - it seems like only one person can use the app at a time, with a minimum of a 5 minutes break between sessions.

  1. There is no session manager in WebApps Server as of R2019a. You can find incoming connection and exit from Web App Server log files (default location in Windows is C:\ProgramData\MathWorks\webapps\R2019a\logs). But I think it's hard to understand how many current sessions are.
  2. You can set timeout from Web App Server configurations. By default, it is set to 5 minutes. For detail please see the sesion timeout of this document (Configure MATLAB Web App Server).

No, Web Apps Server supports simultaneous multiple sessions. You can change maximum sessions by increasing MaxWorkers in $MATLAB_Runtime\bin\win64\webapps.config file and restart Web Apps Server. Though, as of R2019a, maximum sessions is 32 as described in this document.

Thanks for the answer!
32 sessions would be great, but the server only supports 1 session at the moment (although 32 is specified as the maximum number in the config file)...
Is there a way to fix this?
Alternatively, is there a way to time-out the session after 5 minutes, even if the app is still open on someone's browser?
Best,
