ORA-29861

Hi,

I am updating a geometric point and am getting the following errors :

SQL> update meshuser.mps m set m.geometry.sdo_gtype = 2001, m.geometry.sdo_srid = 8307;
update meshuser.mps m set m.geometry.sdo_gtype = 2001, m.geometry.sdo_srid = 8307
                *
ERROR at line 1:
ORA-29861: domain index is marked LOADING/FAILED/UNUSABLE 

All the indexs I saw were valid ? 

Ideas ?

Thanks

Jeff
