"index must be partitioned"
*Cause: Index whose ID was supplied by the user as the second
argument to tbl$or$idx$part$num was not partitioned
*Action: Second argument passed to tbl$or$idx$part$num must be an
object ID of a partitioned index defined on the table whose
name was supplied as the first argument if one desires to determine
mapping into an index partition or 0 if one desires to
determine mapping into a partition of the base table itself
