  --  OVERVIEW
  --
  --  This package provides tablespace/segment space administration
  --  not available through the standard sql.

  --  SECURITY
  --
  --  run with SYS privileges. thus any user who has privilege to execute the
  -- the package gets to manipulate the bitmapes.

  --  CONSTANTS to be used as OPTIONS for various procedures
  --  refer comments with procedure(s) for more detail

  SEGMENT_VERIFY_EXTENTS         constant positive := 1;
  -- used to verify that the space owned by segment is appropriately reflected
  -- in the bitmap as used
  SEGMENT_VERIFY_EXTENTS_GLOBAL  constant positive := 2;
  -- used to verify that the space owned bu segment is appropriately reflected
  -- in the bitmap as used and that no other segment claims any of this space
  -- to be used by it
  SEGMENT_MARK_CORRUPT          constant positive := 3;
  -- used to mark a temp segment as corrupt whereby facilitating its
  -- elimination from the dictionary (without space reclaim)
  SEGMENT_MARK_VALID            constant positive := 4;
  -- used to mark a corrupt temp segment as valid. Useful when the corruption
  -- in the segment extent map or elsewhere has been resolved and the segment
  -- can be dropped normally
  SEGMENT_DUMP_EXTENT_MAP       constant positive := 5;
  -- dump the extent map for a given segment
  TABLESPACE_VERIFY_BITMAP      constant positive := 6;
  -- verifies the bitmap of the tablespace with extent maps of the segments
  -- in that tablespace to make sure everything is consistent
  TABLESPACE_EXTENT_MAKE_FREE   constant positive := 7;
  -- makes this range (extent) of space free in the bitmaps
  TABLESPACE_EXTENT_MAKE_USED   constant positive := 8;
  -- makes this range (extent) of space used in the bitmaps
