Locator Error ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine

Question

I am trying to setup Intermedia Locator and am trying to create the Locator index per the code below. Any ideas why I am getting the below error, and what I can do about it.
Oracle8i Enterprise Edition Release 8.1.6.0.0 - Production
With the Partitioning option
JServer Release 8.1.6.0.0 - Production
SQL> desc zip_codes
Name Null? Type
ZIPC_ZIP5 NOT NULL VARCHAR2(5)

ZIPC_GEOCODE_RESULT MDSYS.GEOCODE_RESULT
SQL> execute geocoder_http.setup_locator_index('zip_codes','zipc_sdo_geometry');
BEGIN geocoder_http.setup_locator_index('zip_codes','zipc_sdo_geometry'); END;
ERROR at line 1:

Hi Raju,
There are a few things I would change below.
The first is that optimized rectangles (which you are using) need to be specified as lower left then upper right, assuming the lowest values are in the lower left corner of the coordinate system.
The way you've specified them is upper left, lower right which will not work.
The second thing I would change is your create index statement. You shouldn't be using locater to create the index - locator is a separate product should be used only with point geometries.
Your create index statement should look something like this:
create index zonetemp_sidx on zonetemp(shape)
indextype is mdsys.spatial_index
parameters ('sdo_level=NN');
where NN above is an integer number representing the tiling level you are going to use for the index. This is workload dependent, but I will give you a range of 8-12 to start with - you can protype using real data and figure out what gives you the best performance - if it is 12 you may want to go higher.
Also, you will have had to preload user_sdo_geom_metadata.
Finally, your query looks good, although I would change it slightly to set the third ordinate to NULL rather than 0, i.e.:
SELECT NAME
FROM ZONETEMP A
WHERE SDO_FILTER (A.SHAPE,
MDSYS.SDO_GEOMETRY(2001,null,
MDSYS.SDO_POINT_TYPE(20,20,NULL),
NULL, NULL)),'QUERYTYPE='WINDOW')
='TRUE'
Hope this helps,
