Using Oracle Views with Mapguide / FDO

Using views in Oracle is a good way to access data via Mapguide/FDO,
but in order to be able to select a feature, it must have a primary key,
otherwise, selection will fail.

This is the SQL syntax to add a primary key on an Oracle View
alter view add constraint primary key () disable novalidate;

Once the view has a primary key, selection becomes available.

Performance Tip for Mapguide Tiled layers with Fusion

Internally, Fusion uses OpenLayers to display maps. By default, titled maps use a buffer factor of 2

This buffer setting determines how many off screen tiles are loaded, you can tweak this option using the following syntax in your ApplicationDefinition.xml

                        <ResourceId>Library:// .....</ResourceId>

Setting buffer:0 means that only the initially visible tiles are loaded, which means as you pan, the tiles are loaded as required
