SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT and "NULL" in SDO_GEOMETRY

Question

For the table N_GEOM we have in the SDO_GEOM_METADATA_TABLE:
table_name: N_GEOM
geometry_column: SHAPE
diminfo: SDO_DIM_ARRAY(SDO_DIM_ELEMENT('LONGITUDE', -180, 180, .001), SDO_DIM_ELEMENT('LATITUDE', -90, 90, .001))
srid: 8307
If we validate the geometry SDO_GEOMETRY(NULL, 8307, NULL, NULL, NULL)
we get:
SQL> select sdo_geom.validate_geometry_with_context(SDO_GEOMETRY(NULL, 8307, NULL, NULL, NULL),
2 diminfo)
3 from user_sdo_geom_metadata where table_name='N_GEOM';
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(SDO_GEOMETRY(NULL,8307,NULL,NULL,NULL),D
NULL
SQL> select sdo_geom.validate_geometry_with_context(NULL,
2 diminfo)
3 from user_sdo_geom_metadata where table_name='N_GEOM';
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(NULL,DIMINFO)
NULL
But if we use a tolerance value we get:
SQL> select sdo_geom.validate_geometry_with_context
2 (SDO_GEOMETRY(NULL, 8307, NULL, NULL, NULL),
3 0.001) from dual;
select sdo_geom.validate_geometry_with_context
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "MDSYS.SDO_GEOM", line 70
ORA-06512: at "MDSYS.SDO_GEOM", line 1851
But witht NULL we get:
SQL> select sdo_geom.validate_geometry_with_context
2 (NULL,
3 0.001) from dual;
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(NULL,0.001)
NULL
Why do we an error message for one these queries?

Answer 1

There is no such SRID 2000303. However, this one sure looks like it does the same thing. Replace all the SRID values with 2320 and you should be set.
