Data Hub Version 1 Export

Using a Dedicated Data Hub Cron

The LMS relies on a timed procedure, know as a cron process, to run many recurring tasks such as sending notifications of forum subscription updates, running reports, and updating course and activity completions. By default, Data Hub also uses the LMS cron to process import and export files. When these export files become extremely large (such as when performing a non-incremental export) they may take too long to run, causing other operations to fail to run.

To address this issue it is possible to establish a separate system-level cron process dedicated to triggering Data Hub processes by itself which will not impact the LMS cron from running regularly.

To pursue this solution, Remote Learner support must assist in the establishment of the new system-level cron process dedicated to Data Hub.

Once Remote Learner establishes the process, disable the Data Hub plugin from running in the LMS cron. This will remove the triggering of Data Hub from the LMS cron.

Location

Navigate to Site Administration ► Plugins ► Local plugins ► Data Hub Settings and activating the Disable in Moodle cron option.

Remember: Activating the Disable in Moodle cron option does not setup the separate, Data Hub specific cron process. It simply removes the Data Hub trigger from the standard LMS cron, meaning Data Hub will no longer run until it is triggered from another process. Remote Learner support will have to configure the server to run the dedicated cron to process the Data Hub files.
