V10.2.0.2 using mapviewer (EA11 and 10.1) to display index MBRs

Question

I'm new to Spatial and GIS, and trying to confirm that my spatial indexes are ok.
I'm trying to view my spatial index mbr along with the geometry in the table using the mapviewer. When I set the SRID to a valid number (4269, 8285) the index mbr is displayed nowhere near the geometry in the table (i.e. the geom in the table is in california, the mbr looks like it's in africa). If I us an invalid srid (6269, there is an ora error, but the index creates anyway), then the mbr displays where I expect it to: around the geometry in the table.
My questions are 1) is this a valid way to display the index mbr? and, if so, 2) what's going on?
I used both the java and sqlldr shapefile converters to load the data with a valid (4269) and invalid (6269) SRID with the same results, as above.
I used this procedure to chg the srid:
1) drop the spatial index
2) update geomtable a set a.geom.sdo_srid=____;
3) update user_sdo_geom_metadata set srid=____ where table_name= 'geomtable' and column_name='GEOM'
4) create index geomtable_sidx on geomtable(geom) indextype is mdsys.spatial_index parameters ('tablespace=indextbs')
I used this query to display the mbr in mapviewer:
select sdo_root_mbr from user_sdo_index_metadata where sdo_index_name =
(select index_name from user_sdo_index_info where table_name = 'GEOMTABLE')
I'd appreciate any ideas!!!
thanks!

Hi,
why you don't take the mbr from the user_sdo_geom_metadata?
