DCAL Download Schedules prevent unexpected network usage by controlling when the software packages are delivered to the DCAL server from the Enterprise application server.
When a hotfix is added to the CAL deployment schedule, the system automatically deploys the major version (for example, GR) first, followed by the hotfix. When using Distributed CAL (DCAL), both the major version and the hotfix must be added to the DCAL download schedule, downloaded, and available in the DCAL server before the POS client update can be scheduled.
You need to configure Deployment Schedules to deploy CAL packages to the Service Hosts. Without Deployment Schedules, CAL packages are stored on the DCAL server and are not deployed to the Service Hosts. Adding a Deployment Schedule for One CAL Package contains more information about scheduling CAL packages to deploy at preset times.
