to set a property on the layer like InvalidateDate that would force

Oracle to invalidate the tile cache for affected layers. I'd prefer this
method to just deleting the cache, because of the huge file IO caused by the
delete, and because it would reduce fragmentation of the volume. This
would be usable by other external processes, such as daily SDF updates

the current functionality of base layers is that they don't update
themselves based on an underlying data change regardless of the source data
type. This would be up to you to delete the images from your TileCache
directory to force them to rebuild the next time somebody viewed that map
area.</SPAN></FONT><o:p></o:p></P>

anyone that has tested it already) know if I use Oracle Spatial data for my
