Babu,

While you're waiting, run this query to see what you're waiting on.

Jared

select

   s.username username,
   e.event event,
   s.sid,
   e.p1text,
   e.p1,
   e.p2text,
   e.p2,
   e.wait_time,
   e.seconds_in_wait,
   e.state

from v$session s, v$session_wait e
where s.username is not null

and s.sid = e.sid
and s.username like upper('&uusername')

skip sqlnet idle session messages and e.event not like '%message%client' order by s.username, upper(e.event);

Jared,

It is taking 30 to 40 minutes to respond. I just issued again and is sitting
there. Iam sure it would respond after 30 minutes as happenned many times.

I would E-Mail after getting the response.

Thanks,

Dear List,

When I query dba_extents , Iam getting response after half an hour to 40 minutes, but when I query any other dictionary view it is spontaneous. Everything else is fine in the database and there are no problems, except the above problem. Iam not getting any clue how to fix this. Iam thinking of
running catalog.sql and catproc.sql as a last resort. Iam not sure it would
fix the problem. Please let me know if there is any other way to fix this problem.

Thanks,
Babu
