Clearing Datafor Repository

The Datafor repository (JCR) often retains a large amount of unused data after multiple migrations from the same repository. This leads to increased table sizes and a slowdown of the repository. You can clean up this unused data in the JCR by enabling a system listener designed for this purpose. Cleaning the JCR can only be done when no users are logged in, and the repository remains locked while the process is running.

Steps:​

  1. Stop the Datafor server.

  2. Locate the datafor-server/Datafor-solutions/system directory and open the systemListeners.xml file with any text editor.

  3. Add this bean as the last item within the list tags

    <bean id="repositoryCleanerSystemListener" class="org.Datafor.platform.plugin.services.repository.RepositoryCleanerSystemListener">
        <property name="gcEnabled" value="true"/>
        <property name="execute" value="now"/>
    </bean>

  4. Save and close the systemListeners.xml file, then restart the Datafor server.

Configuration Options:​

You can customize the settings for the repositoryCleanerSystemListener by editing these properties. It is recommended to clean up the Datafor repository on a regular schedule.

PropertyDescription
gcEnabledBoolean flag to turn the listener On (true) or Off (false).
executeYou can choose when to run the listener: now (runs once during server start-up), weekly (runs on the first day of each week), monthly (runs on the first day of each month).
