[mapserver-users] MapServer, WFS and Oracle

Jelmer,

Also, when using WFS from Oracle, you should add the wfs_extent or
ows_extent metadata tags. Otherwise MapServer will request Oracle to do a
convex_hull to get the extent of your data. On large datasets, this can take
a while. Setting the extent metadata tag bypasses this check and uses the
value you specify.
