Home -> Community -> Mailing Lists -> Oracle-L -> RE: Which session is killing performance?
HI Craig, try these scripts
set linesize 200
column username format a15
column idle format a10
column machine format a22
column terminal format a15
column program format a15
select sid, serial#, username, -- process, to_char(logon_time,'DDth - HH24:MI:SS') logon, terminal, program, -- floor(last_call_et/3600)||':'|| -- floor(mod(last_call_et,3600)/60)||':'|| -- mod(mod(last_call_et,3600),60) IDLE, status from v$session where username is not null order by sid
and to see what they are doing
column command format a60
column sid format 99
column serial# format 999999
SET PAGESIZE 100
set linesize 120
SELECT u.sid, u.serial#, SUBSTR(u.username,1,12) user_name, s.sql_text command FROM v$sql s, v$session u WHERE s.hash_value = u.sql_hash_value AND sql_text not like '%from v$sql s, v$session u%' and u.username is not null ORDER BY u.sid
If there is an application server involved you may not be able to pinpoint exactly who is logged in and from where, but for direct connections this works fine.
Hope this helps

Newbie question time:
We have 8.1.7 running on Win 2000 with about 50 users. The system has just slowed down dramatically for about 5 minutes, with lots of user complaints. I suspect one of the developers was loading data or doing some DML. But how do I find who it is? I found a small piece of code on AskTom that returned a user whose SQL has been running longer that x seconds, but this wont necessarily be the user I'm looking for, will it?. Is there something in v$session I should be looking at?
Any help appreciated
