Common errors

Teacher application

Common errors and warnings visible in the web application for teachers (https://dashboard.exams.schoolyear.app).

Your organisation has reached its limit of concurrent Secure Apps sessions at the planned timeslot. Move your exam to a quieter moment.

This warning prevents teachers from planning an exam that will exceed the available quota.

Possible causes:

1. There is not enough quota to serve the number of students configured in the exam.
2. There are other exams planned in an overlapping timeslot which together with the new exam would exceed the available quota.
3. You misconfigured the available quota.
4. You misconfigured the quota calculation in the AVD Add-on.

1 & 2: In the first two situations, the message prevents the user from doing something that will result in a deployment failure. The scheduling tool is working as it is supposed to. If your users often run into this issue, you can request a quota increase in Azure and adjust the Schoolyear quota configuration to reflect the new quota limit.

Note that quotas are reserved from the moment the deployment job of an exam starts until the end of the deletion job. This means that two exams planned back-to-back are considered overlapping and cannot use the same quota.

3 & 4: If you do have enough quotas to plan the exam but do get this warning, you probably misconfigured the quotas. In the “Quota” section of the Schoolyear Admin dashboard, you can configure how much quota there is available in total to Schoolyear AVD. Check if this number reflects the number of quota you have available in your Azure Subscription.

In the AVD Add-on, you can configure per App how Schoolyear should calculate how much quota should be reserved for an exam. The required quota is usually dependent on the number of students that participate in the exam. Therefore, you can configure a formula in which “n” is the number of students. See the AVD Add-on documentation for more information.
