Hi Fernando,
now i found the time to answer your reply. SORRY ;-)
Until now, I did not write the question into the Oracle Spatial forum. I will do it after giving you some new examples. (This is not as important for me as the examples for you, because the "wrong" geometries are drawn correctly by mapserver ! Only some of the correct stored geometries are not drawn !)
1.) A "circle" which is not drawn, and a error is reported
==========================================================
(Table=ax_gebaeude, Fid=14083066, only for me to find the objects again !)
SDO_GEOMETRY(2003, 82032, NULL, SDO_ELEM_INFO_ARRAY(1, 5, 1, 1, 2, 2), SDO_ORDINATE_ARRAY(4512485,81, 5426487,22, 4512491,74, 5426479,73, 4512485,28, 5426472,69, 4512477,01, 5426480,27, 4512485,81, 5426487,22))
The geometry validates (SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(c.geom, 0.005)), but the use of "5" as an SDO_ETYPE is discouraged by Oracle. So the following (mapserver) error message is okay:
- <ServiceExceptionReport version="1.1.1">
<ServiceException>msDrawMap(): Image handling error. Failed to draw layer named 'stgk_gebaeude_orcl'. msDrawShape(): General error message. Only polygon shapes can be drawn using a POLYGON layer definition.</ServiceException>
</ServiceExceptionReport>
2.) Some "circles" which are drawn correctly by mapserver
=========================================================
(Table=ax_bes_geblinie, Fid=14196364 - 14196267)
SDO_GEOMETRY(2002, 82032, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 2), SDO_ORDINATE_ARRAY(4512475,44, 5426583,82, 4512473,81, 5426582,19, 4512475,44, 5426580,55, 4512477,08, 5426582,19, 4512475,44, 5426583,82))
SDO_GEOMETRY(2002, 82032, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 2), SDO_ORDINATE_ARRAY(4512475,24, 5426579,96, 4512473,6, 5426578,32, 4512475,24, 5426576,67, 4512476,88, 5426578,32, 4512475,24, 5426579,96))
SDO_GEOMETRY(2002, 82032, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 2), SDO_ORDINATE_ARRAY(4512474,96, 5426569,9, 4512474,1, 5426569,04, 4512474,96, 5426568,19, 4512475,82, 5426569,04, 4512474,96, 5426569,9))
SDO_GEOMETRY(2002, 82032, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 2), SDO_ORDINATE_ARRAY(4512475,08, 5426574,78, 4512474,24, 5426573,95, 4512475,08, 5426573,11, 4512475,92, 5426573,95, 4512475,08, 5426574,78))
These "circles" are made up of a connected sequence of circular arcs (SDO_ETYPE=2 AND SDO_INTERPRETATION=2). All "circles" are validating. Mapserver draws them correctly.
"LINESTRING made up of a connected sequence of circular arcs." (Oracle Spatial 9i Documentation)
3.) Some "circles" which are validating by Oracle Spatial, not drawn by mapserver, no error message is generated
================================================================================================================
(Table=ax_gebaeude, Fid=14079065, 14079126, 14079128, 50153783)
The statement:
Select fid, geom, SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(geom, 0.005)
FROM ax_gebaeude
WHERE Fid=14079065
or fid=14079126
or fid=14079128
or fid=50153783;
The result:

TRUE
The geometries are validating. No error is reported. The geometries are NOT drawn ba mapserver.
I think, the combination of SDO_ETYPE=1003 and SDO_INTERPRETATION=2 is valid: "POLYGON made up of a connected sequence of circular arcs that closes on itself. ....) (Oracle Spatial 9i Documentation)
That is just the description of the picture which should be drawn !!!
Note: COMPOUND POLYGONS with circular arcs are drawn
====================================================
If there is a COMPOUND POLYGON with some vertices connected by straight line segments and some by circular arcs, this PLOYGON is drawn correctly. The geometry validates by Oracle Spatial.
Statement:
Select fid, geom, SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(geom, 0.005)
FROM ax_gebaeude
WHERE Fid=14080250;
Result:
14080250
SDO_GEOMETRY(2003, 82032, NULL, SDO_ELEM_INFO_ARRAY(1, 1005, 2, 1, 2, 2, 13, 2, 1), SDO_ORDINATE_ARRAY(4507524,52, 5430348,32, 4507526,76, 5430348,68, 4507528,88, 5430349,49, 4507531,16, 5430351,04, 4507532,99, 5430353,11, 4507534,27, 5430355,63, 4507534,86, 5430358,4, 4507537,64, 5430358,38, 4507537,65, 5430358,56, 4507537,71, 5430358,56, 4507537,72, 5430366,92, 4507538,53, 5430366,92, 4507538,6, 5430382,06, 4507535,31, 5430382,07, 4507479,2, 5430382,24, 4507479,18, 5430374,96, 4507479,16, 5430366,28, 4507478,79, 5430366,28, 4507478,73, 5430340,61, 4507484,01, 5430340,91, 4507505,57, 5430342,15, 4507524,53, 5430343,3, 4507524,52, 5430348,32))
TRUE
Conclusio:
==========
LINESTRING's making a connected sequence of circular arcs are drawn, even if they are closing on themselves.
If a POLYGON made up ONLY of circular arcs AND it CLOSES ON ITSELF, it is NOT drawn.
If there are arcs in a COMPOUND POLYGON, the whole Polygon is drawn correct.
All geometry-types are validating by Oracle Spatial, the used combination of SDO_ETYPE and SDO_INTERPRETATION is okay.
I really think, that this a problem of mapserver's Oracle-driver !
