Problem by adding one spatial column to the version-enabled table

Question

Hello, I'm trying to modify one version-enabled table T1 like this:
--table definition
create table T1
(ID NUMBER NOT NULL PRIMARY KEY,
NAME VARCHAR2 (256),
FUNCTION VARCHAR2 (256));
--enable versioning
EXECUTE DBMS_WM.EnableVersioning('T1','VIEW_WO_OVERWRITE');
I'd like to add one spatial column to this table by:
-- modify metada view for spatial indexing
INSERT INTO USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
VALUES ('T1_LT', 'ANCHOR',
MDSYS.SDO_DIM_ARRAY
(MDSYS.SDO_DIM_ELEMENT('X', 0.000, 100000.000, 0.0005),
MDSYS.SDO_DIM_ELEMENT('Y', 0.000, 100000.000, 0.0005),
MDSYS.SDO_DIM_ELEMENT('Z', -100, 1000, 0.0005)) , 81989002);
-- table modification - add a column and create a spatial index
EXECUTE DBMS_WM.BeginDDL('T1');
ALTER TABLE T1_LTS ADD ("ANCHOR" MDSYS.SDO_GEOMETRY);
CREATE INDEX T1_SPX on T1_LTS(ANCHOR) INDEXTYPE is MDSYS.SPATIAL_INDEX;
EXECUTE DBMS_WM.CommitDDL('T1');
By finishing of the DDL operation with EXECUTE DBMS_WM.CommitDDL('T1') I get an error message:
"SQL> EXECUTE DBMS_WM.CommitDDL('T1');
BEGIN DBMS_WM.CommitDDL('T1'); END;
ERROR at line 1:
ORA-20171: WM error: 'CREATE TABLE' and 'CREATE SEQUENCE' privileges needed.
ORA-06512: at "SYS.WM_ERROR", line 342
ORA-06512: at "SYS.WM_ERROR", line 359
ORA-06512: at "SYS.LTUTIL", line 8016
ORA-06512: at "SYS.LT", line 11925
ORA-06512: at line 1
What is wrong here? The Oracle 10g DB is installed on Windows 2003 Server, OWM_VERSION - 10.2.0.1.0.

Hi,
You need to explicitly grant the create table and create sequence privileges to the user owning the table. It is not enough for these to be granted by using a role. This restriction is documented in the user guide.
Also, you should add the entry in the user_sdo_geom_metadata view on the t1_lts table, which is the table to which you are actually adding the geometry column, after calling beginDDL. CommitDDL will make the necessary changes, which in this case would be to add an entry for both t1 and t1_lt.
