create or replace package dbms_space_admin is ------------ -- 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 SEGMENT_VERIFY_BASIC constant positive := 9; SEGMENT_VERIFY_DEEP constant positive := 10; SEGMENT_VERIFY_SPECIFIC constant positive := 11; HWM_CHECK constant positive := 12; BMB_CHECK constant positive := 13; SEG_DICT_CHECK constant positive := 14; EXTENT_TS_BITMAP_CHECK constant positive := 15; DB_BACKPOINTER_CHECK constant positive := 16; EXTENT_SEGMENT_BITMAP_CHECK constant positive := 17; BITMAPS_CHECK constant positive := 18; TS_VERIFY_BITMAPS constant positive := 19; TS_VERIFY_DEEP constant positive := 20; TS_VERIFY_SEGMENTS constant positive := 21; SEGMENT_DUMP_BITMAP_SUMMARY constant positive := 27; NGLOB_HBB_CHECK constant positive := 12; NGLOB_FSB_CHECK constant positive := 13; NGLOB_PUA_CHECK constant positive := 14; NGLOB_CFS_CHECK constant positive := 15;
