Sdo.relate error

Question

Hello,
I'm trying to select all points from POINTABLE that are within a polygon (AAAMAY00) that exist in a HDW_POLYGONS table.
I'm using Oracle Spatial 8.1.5. and I'm using the following statement:
select a.GEOM.SDO_point.x, a.GEOM.SDO_point.Y, a.DEPTH
FROM POINTABLE a, HDW_POLYGONS m
WHERE m.PROJECT_ID= 'AAAMAY00'
AND mdsys.SDO_relate(a.GEOM, m.GEOM,
'mask=ANYINTERACT querytype=WINDOW layer_gtype=POINT') = 'TRUE'
After running this query I get this error:
ERROR:
ORA-03106: fatal two-task communication protocol error
Any Help?

Hi Aldino,
Off the top of my head I don't know what is wrong, and I don't have 8.1.5 installed. There were some pretty major memory leaks in sql*plus that got fixed in 8.1.6 - it is possible you are running into that. Try the query without selecting the x and y values from the object.
Another thing to look at (if that isn't the problem) is using an Oracle hint in this query:
select /*+ ordered */ a.GEOM.SDO_point.x,
a.GEOM.SDO_point.Y, a.DEPTH
FROM HDW_POLYGONS m, POINTABLE a
WHERE m.PROJECT_ID= 'AAAMAY00'
AND mdsys.SDO_relate(a.GEOM, m.GEOM,
'mask=ANYINTERACT querytype=WINDOW
layer_gtype=POINT') = 'TRUE';
Those are the only two things I can thing of...
