Syntax options:

    FILL RANDOMLY | FILL SEQUENTIALLY

    Specifies whether to fill the area set randomly or sequentially.
    Specifying FILL RANDOMLY or FILL SEQUENTIALLY requires a FOR
    clause. When a storage area is filled, it is removed from the
    list of available areas. Oracle Rdb does not attempt to store
    any more lists in that area during the current database attach.
    Instead, Oracle Rdb starts filling the next specified area.

    When a set of areas is filled sequentially, Oracle Rdb stores
    lists in the first specified area until that area is filled.

    If the set of areas is filled randomly, lists are stored across
    multiple areas. This is the default. Random filling benefits from
    the I/O distribution across the storage areas.

    The keywords FILL RANDOMLY and FILL SEQUENTIALLY can only be
    applied to areas contained within an area list.
