ORA-01632

Error: ORA-01632: max # extents (string) reached in index string.string

Causa: An index tried to extend past MAXEXTENTS.

Acción: If the value of MAXEXTENTS in the index storage clause is less than the maximum (based on your block size), raise it. Otherwise, re-create the index with larger extent sizes so that the total number of extents falls below the maximum.
