No result when geocoding via PL/SQL

Dear community,

I am trying to geocode an unformatted address and returns the result as an SDO_GEOMETRY object.

Looking at this closer I have to use GEOCODE_AS_GEOMETRY function from package SDO_GCDR.

Point of view database spatial components are looking at first glance good point of view setup:

select comp_id, comp_name, version, status from dba_registry where comp_id in ('JAVAVM','ORDIM','XDB','SDO');

COMP_ID         COMP_NAME                     VERSION         STATUS

------------------------ -------------------------------------------------- ------------------------ ------------------------

JAVAVM          JServer JAVA Virtual Machine            12.2.0.1.0        VALID

XDB           Oracle XML Database                12.2.0.1.0        VALID

ORDIM          Oracle Multimedia                 12.2.0.1.0        VALID

SDO           Spatial                      12.2.0.1.0        VALID
