To correct this error, the database administrator must reorganize the
entire segment and appropriately increasing the size of the extents to
be created (and, if necessary, their percentage growth).
Since this reorganization will also correct any fragmentation of the
storage space, it can often solve the problem even if the extent size
is kept the same.
Any reorganization of the database should only be performed by a
database administrator.

exceeded.
