Podskazhite Pls kak byt jesli SYStem RBS poluchil Invalid?

A chego neponyatnogo:

SELECT /*+ ORDERED ALL_ROWS*/
undo.name name,
ts.name tablespace,
us.name username,
DECODE(undo.status$,1,'Invalid',
2,'Avail',
3,'In Use',
4,'Offline',
5,'Needs Recovery') status,
ROUND(seg.blocks * ts.blocksize /(1024*1024), 2) rb_size,
seg.minexts minexts,
seg.extents extents,
seg.maxexts maxexts,
ROUND(seg.iniexts * ts.blocksize / (1024*1024), 2) iniexts,
ROUND(seg.extsize * ts.blocksize / (1024*1024), 2) extsize,
v.xacts xacts,
v.extends extends,
v.shrinks shrinks,
v.wraps wraps,
ROUND(v.aveshrink/(1024*1024) ,2) avg_shrink,
v.gets gets,
v.writes writes,
v.waits waits,
ROUND(v.rssize/(1024*1024), 2) rssize,
ROUND(v.optsize/(1024*1024), 2) optsize
FROM sys.undo$ undo,
sys.ts$ ts,
sys.seg$ seg,
sys.user$ us,
sys.v_$rollstat v
WHERE ts.ts# = undo.ts#
AND ts.ts# = seg.ts#
AND seg.file# = undo.file#
AND seg.block# = undo.block#
AND seg.user# = us.user#
AND v.usn (+) = undo.us#

Poluchaju sled. Rezultat:

SYSTEM SYSTEM SYS Invalid 0,16 2 2 505 0,05 0,05 0 0 0 0 0 21046 26974 0 0,15 0
i.t.d....

Prosto ubit nelzya, uzhe ubil.

V select * from dba_rollback_segs;
sledov ot etogo RBS88 netu.
Pokazyvajet moi RBS kak i polozheno.

no:
select undo.name,DECODE(undo.status$,1,'Invalid',
2,'Avail',
3,'In Use',
4,'Offline',
5,'Needs Recovery') status,
seg.minexts minexts,
seg.extents extents,
seg.maxexts maxexts,seg.block#
FROM sys.undo$ undo,sys.seg$ seg
where
seg.block# = undo.block#
and undo.status$ =1;

vydajet mne:

NAME STATUS MINEXT EXTENTS MAXEXT seg.block#
RBS88 Invalid 1 1 505 11754

zatem delayu:

select * from seg$
where block#=11754;

i poluchaju vse na segment kotoromu block# 11754 prinadlezhit.

No RBS to uzhe ubit, chego eta padla sootvetstvujuschije blocki ne poubivala.

Otkryl TAR na Metalinke. Mozhet byt oni chem pomogut.

a kto mne pozvolit na produktivnoj baze bez Razreschenija ORACLE- Support systemnuju tablizu updatity?
