Debugging data in spatial

Question

I have shape file converted to oracle spatial fromat using shp2sdo.exe.
I did load the data but when I try to validate it , give me the following .I do understand that 13349 means self crossing and 13356 means duplicates .
How do I eliminate these error . The data is huge (2227) rows.I have no clue which co ordinates in which polygon is incorrect.Is there a way I can debugg this data ?Please help.
SQL> SELECT * FROM VALIDATE_RESULTS;

Answer 1

please the meta data :I dont think this is the problem with tolerance.
But can I use sdo_union on the geometry itself to correct this error . Will this cause error in the object geometry.
