RE: Monitoring Unix Question

RE: Monitoring Unix Question
If you have the "top" utility installed on the Unix box, this makes an easy to use interface to identify CPU hogs. For non-root users to run it, your sys admin might have to change default permissions on certain "files" such as /dev/kmem; or possibly make top SUID root. If you don't have top, or you can't run it as non-root, you can try using the following ps command to sort things by %CPU, but I think there might be differences among OS's on some of the more exotic ps and sort options: ps -eo pid -o %cpu | sort -rk2 | head -20 After you have identified which PID is the hog, and can see that it is a dedicated server process, you can run something like the following to match SID & SERIAL# to the correct OS process ID. If you must brutally kill the process, kill the session in the database, then kill the pid in the OS. set linesize whatever_you_like set pagesize whatever_you_like col username format a15 col osuser format a15 select s.username, s.osuser, s.sid, s.serial#, s.process "USER PRCS", p.spid "SVR PRCS" from v$process p,v$session s where p.addr = s.paddr and s.username <> ' ' / > -Original Message- > From: ecandrietta [mailto:ecandrietta@;uol.com.br] > Sent: Thursday, November 14, 2002 1:20 PM > To: Multiple recipients of list ORACLE-L > Subject: Monitoring Unix Question > > > > Friends : > > How can i do for get what is running inside a PID that is > using a lot of CPU ? > > How can I get the query that is running inside the database > according PID of unix ? > > I would like to know commands of the unix and the query that > i need to run in the database for find out the problem. > > Regards > > Eriovaldo > > > > --- > UOL, o melhor da Internet > http://www.uol.com.br/ > > -- > Please see the official ORACLE-L FAQ: http://www.orafaq.com > -- > Author: ecandrietta > INET: [EMAIL PROTECTED] > > Fat City Network Services-- 858-538-5051 http://www.fatcity.com > San Diego, California-- Mailing list and web hosting services > - > To REMOVE yourself from this mailing list, send an E-Mail message > to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in > the message BODY, include a line containing: UNSUB ORACLE-L > (or the name of mailing list you want to be removed from).

Re: Monitoring Unix Question
In V$PROCESS there is SPID (or something similar) which is the OS pid. Then, you can join to V$SESSION on ADDR / PADDR hth connor --- ecandrietta <[EMAIL PROTECTED]> wrote: > > Friends : > > How can i do for get what is running inside a PID > that is > using a lot of CPU ? > > How can I get the query that is running inside the > database > according PID of unix ? > > I would like to know commands of the unix and the > query that > i need to run in the database for find out the > problem. > > Regards > > Eriovaldo > > > > --- > UOL, o melhor da Internet > http://www.uol.com.br/ > > -- > Please see the official ORACLE-L FAQ: > http://www.orafaq.com > -- > Author: ecandrietta > INET: [EMAIL PROTECTED] > > Fat City Network Services-- 858-538-5051 > http://www.fatcity.com > San Diego, California-- Mailing list and web > hosting services > - > To REMOVE yourself from this mailing list, send an > E-Mail message > to: [EMAIL PROTECTED] (note EXACT spelling of > 'ListGuru') and in > the message BODY, include a line containing: UNSUB > ORACLE-L > (or the name of mailing list you want to be removed > from).

Monitoring Unix Question
Friends : How can i do for get what is running inside a PID that is using a lot of CPU ? How can I get the query that is running inside the database according PID of unix ? I would like to know commands of the unix and the query that i need to run in the database for find out the problem.
