Without knowing what spatial reference system (SRS) your data is in, it is hard
to tell you specifically if anything is wrong. How does the map created
MapServer look? Does it display your data correctly, does it line up with
your other data? If so, success.
If your data is in a SRS that uses geographic coordinates (lat/long), the
maximum valid x value would be 180 and the maximum y value would be 90. I
haven’t tested whether MapServer will forgive values outside of that range or
continue around the globe, but they are incorrect.
If your data is in a SRS that uses kilometers (as you set your second UNITS
block), you are mapping an area ~400k x ~300k.
What does your GIS tell you about the data’s SRS?

i already found the problem STATUS to DEFAULT.
then why my mapfile's EXTENT look weird? i looked at Propertise->Source of the
shapefile in Arcgis, it mention about the Extent, then i write it in Mapfile.
is it wrong?
Thanks Mr. David

I see a few potential issues with your mapfile:
1.For testing, set your layer STATUS to DEFAULT or add
‘&layer=tb_kasusdbd’ to your URL
2. You have two entries for UNITS (DD and KILOMETERS). You should only
have one of these lines, and the units should match the units of your output
projection. So, if your data really is in geographic coordinates (lat/long),
your units should be ‘DD’.
3. The values in your EXTENT line look weird. The values in your EXTENT
need to be expressed in the units used by your output projection/spatial
reference system. If your data is in geographic coordinates, these values are
invalid. If your data is in some other spatial reference system, you will need
to change your UNITS to match that SRS.

Good day all,
i want to ask, i have file shp that already convert to Postgis, then i want to
appear it in mapfile named:map_postgis.map then check in:
http://localhost/cgi-bin/mapserv.exe?map=i:/Spatial/mapfile/map_postgis.map&mode=map,
but that i found just background no Map. why?
shp: kec_kasus_DBD
db in postgis: db_SpatialSura
table: tb_kasusdbd
mapfile: map_postgis
for checking: i want to see column 'kecamatan'
here my mapfile:
