I am having one table in dba_segments whose entry is missing in sys.seg$ view.Please refer the below two queries:-

SQL> select OWNER,HEADER_FILE,HEADER_BLOCK
2 from dba_segments
3 where segment_name='TSNPJOBLOG';

OWNER HEADER_FILE HEADER_BLOCK
------------------------------ ----------- ------------
MVIEW_OWNER 76 120872



SQL> select nvl(FILE#,0),nvl(BLOCK#,0),TYPE#,TS#,MAXEXTS,EXTENTS
2 from sys.seg$
3 where file#='76' and block#='120872';

Can anyone please tell what could be the problem.

Thanks,
Pallavi
