Denne viser SQL, der i øjeblikket er "AKTIV":-
select S.USERNAME, s.sid, s.osuser, t.sql_id, sql_text
from v$sqltext_with_newlines t,V$SESSION s
where t.address =s.sql_address
and t.hash_value = s.sql_hash_value
and s.status = 'ACTIVE'
and s.username <> 'SYSTEM'
order by s.sid,t.piece
/
Dette viser låse. Nogle gange går det langsomt, men det er fordi det er blokeret og venter på en lås:
select
object_name,
object_type,
session_id,
type, -- Type or system/user lock
lmode, -- lock mode in which session holds lock
request,
block,
ctime -- Time since current mode was granted
from
v$locked_object, all_objects, v$lock
where
v$locked_object.object_id = all_objects.object_id AND
v$lock.id1 = all_objects.object_id AND
v$lock.sid = v$locked_object.session_id
order by
session_id, ctime desc, object_name
/
Dette er en god en til at finde lange operationer (f.eks. fuld tabelscanninger). Hvis det er på grund af mange korte operationer, vil der ikke dukke noget op.
