Setting up Dispatcher to manage updates (JT)

To set up Dispatcher to manage updates, ensure that you have:

• Installed the following Dispatcher translators, using TEM:

  • JtToBboxAndTso
  • QSearchProcessQueue

  Note: It is recommended that you use only one translator for the spatial search indexer.

• Set the QSEARCH_update_enabled preference to True if you want to generate TSO files.

When a geometry is saved, triggers are automatically set for creation of a JT file, and the spatial index is updated with the Dispatcher setup as follows:

1. Triggers are set for the creation of a JT file.
2. The JT file is created and it requests the Dispatcher to generate the bounding boxes and TSO files.
3. The JT is loaded and the bounding box information is populated into the bounding box table.
4. TSO files are generated and attached as a named reference.
5. A Dispatcher request is triggered, and a spatial index is created.

Note: If you would like to configure the QsearchProcessQueue Dispatcher translator as a recurring request, set the following preferences as required:

• QSEARCH_queue_recurring_background_updates
• QSEARCH_recurring_background_update_survival_time
• QSEARCH_recurring_background_update_interval

If you want to reduce the objects getting added to the queue and also reduce the number of Dispatcher requests, specify the item types you want to avoid in the QSEARCH_types_to_avoid_processing preference.
