i haven't seen anyone mention it yet, so i'll try to be the first happy
mapserver user to thank Rodrigo Cabral for all his work on the
maporaclespatial code.  we've been using it for about a week and its
worked perfectly.

we used oracle shp2sdo utility to convert shape files to oracle
loader format.  we loaded 2.7 million texas tiger 2000 road segments as a
test data set, indexed with oracle's recommended tile size, and have been
viewing and querying with mapserver with no problem.

the nicest part of using oracle spatial with mapserver is being able to
pass standard sql queries either from the map file or by modifiying
the map_layer_data_ .. these can be attribute queries, oracle
spatial queries on geometry, or a combination.  i included a couple of
lines from a map file in case anyone's interested ...
