ORA-29902 ERROR on a querry

Question

We get this error with the following querry:
SELECT
DISTANCE FROM DIST_PTS
WHERE (CLLI = 'CHCGILCL') AND (MDSYS.SDO_NN (GEOLOC,
MDSYS.SDO_GEOMETRY (2001, NULL,
MDSYS.SDO_POINT_TYPE (-87.63804626464844, 41.879520416259766, NULL),
NULL, NULL), 'SDO_NUM_RES=1') = 'TRUE');
ERROR at line 1:
ORA-29902: error in executing ODCIIndexStart() routine
ORA-13236: internal error in R-tree processing: [failed to allocate memory]
ORA-06512: at "MDSYS.SDO_INDEX_METHOD", line 84
ORA-06512: at line 1
Our table has 25 million records and we are using Oracle 8.1.7
We were getting this error with 8.1.6 and were advised to upgrade. We did but we get the same error. Has anyone seen this ?

Answer 1

I am getting a similar error code trying to run the "Nearest
Neighbor" sample code:
error message:
ORA-29902: error in executing ODCIindexStart()routine
ORA-13207: incorrect use of the [NO UNITS SUPPORTED] operator
ORA-06512: at "MYSYS.SDO_INDEX_METHOD" line 83
partial code:
v_latlong := v_latlong.findlocation();
if v_latlong.numTotalCand > 0 then
v_lat := v_latlong.getLatitude(1);
v_long := v_latlong.getLongitude(1);
found3 := FALSE;
dist := .25;
while found3 = false loop
dist := dist + .25;
select a, b, c INTO r_a, r_b, r_c from atable where
SDO_WITHIN_DISTANCE(atable.GEOLOC,MDSYS.SDO_GEOMETRY
(2001,NULL,MDSYS.SDO_POINT_TYPE(v_long,v_lat,NULL),NULL,NULL),
'distance = dist, Unit=MILE, layer_gtype = POINT')
= 'TRUE';
cnt := cnt + 1;
end loop;
if cnt >= 2 then
found3:= TRUE;
end if;
The only references I am finding to the ODCI Index is in the
Oracle Data Cartridge Developers manual. SInce I am not
developing a Data Cartridge, I am assuming the error is coming
from either the Oracle Geocoder or the MapInfo implementation of
that. In either case I do not see how I can correct the
problem.
Is the suggestion that there might be a problem with the
geometry (in my case both are x,y points)?
Thank you for any help
