Don't work spatial index

[Liga Abols]

Hello,
i work with Oracle 9i, i need to make geographic database. I made tables, metadata, and insert date in these tables, but there is a problem with Index.
I have a following error:
CREATE INDEX FIN1_EZERI ON TBL1_EZERI (GEOM)
INDEXTYPE IS MDSYS.SPATIAL_INDEX
PARAMETERS('SDO_LEVEL=6');

ERROR at line 1:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-13249: internal error in Spatial index: [mdidxrbd]
ORA-13249: Error in Spatial index: index build failed

ORA-13369: Invalid value for etype in the 4 digit format
ORA-06512: at "MDSYS.SDO_INDEX_METHOD_9I", line 7

How to fix it?
