function based indexes on object tables

Hi,
I am trying to create a function based index on an object table. I am getting the following error:

SQL> create index cell1_indx on cell1(create_cell1(id)) indextype is mdsys.spatial_index;
create index cell1_indx on cell1(create_cell1(id)) indextype is mdsys.spatial_index
*
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-13249: Stmt-Execute Failure: SELECT num_rows from all_tables where owner='ASHE' and table_name=
'CELL1'
ORA-06512: at "MDSYS.SDO_INDEX_METHOD_9I", line 7
ORA-06512: at line 1

Here cell1 is an object table.
Is the procedure for creating function based indexes on object tables different from relational tables?

Chinni

I am able to drop the index without any error message.

Hi Gurus,

ORA-29855 error occurred in the execution of ODCIINDEXCREATE routine

Cause: Failed to successfully execute the ODCIIndexCreate routine.
Action: Check to see if the routine has been coded correctly.

Can someone guide how to CHECK the routine.
Because this doesn't give a clear picture

Cheers!
