What is the command to kill a SYS session? Let's say someone figured out the SYS password and logged in. Now I want to kill the session. What do I do?

The ALTER SYSTEM KILL SESSION 'SID,SERIAL#' does not work.

Is this user logged directly onto DB server system?
Is this user connected to the DB over the network?

>URGENT!!!!
Please explain why it is URGENT for me to solve this problem for you.

What is Operating System name & version?
What is Oracle version to 4 decimal places?

This is not an Oracle error.

What make you think this is the case?

>He is logged in through sqlplus
>I did ps -ef|grep sqlplus, but it did not give anything

How do you reconcile these two contradictory statements?

>What do I do?
Run in circles & scream & shout "The sky is Falling"!

Ok I don't know if you're trying to be funny or sarcastic, but you don't have to know the reason behind things happening. I just asked How to kill a SYS session. THe command...that's it.

All I am asking is the command please.

Thank you

ALTER SYSTEM KILL SESSION 'SID,SERIAL#' does work.
This session's status be either "KILLED" or "SNIPED"
This session will stay "in the database" while the associated OS process exists.

Its been very difficult to digest Embarassed

Is it giving error? - Post Error
Mention clearly, what is the problem you are facing.

SQL> ALTER SYSTEM KILL SESSION 'sid,serial#';

In some situations the Oracle.exe is not able to kill the session immediately. In these cases the session will be "marked for kill". It will then be killed as soon as possible.

Issuing the ALTER SYSTEM KILL SESSION command is the only safe way to kill an Oracle session. If the marked session persists for some time you may consider killing the process at the operating system level. Witout knowing which process, killing OS processes is dangerous and can lead to instance failures.

It is possible to force the kill by adding the IMMEDIATE keyword:
SQL> ALTER SYSTEM KILL SESSION 'sid,serial#' IMMEDIATE;

Hope this helps you,

Brayan.

This is a dumb question, but are you, by any chance, typing 'sid' and 'serial#' rather than actually typing the values appropriate
e.g. ALTER SYSTEM KILL SESSION '181,2'

Well...I figured it out. It did kill the session, but afterwards I thought there was another SYS session, which was actually mine Smile and I was trying to kill that Razz . What I found out is that you can't kill your own session from SQL, duh. I apologize for the confusion and chaos I caused. I was very upset as somehow the SYS password got out and I was trying to find out who did it and I was trying to kill any sessions that were trying to connect as SYS. I also ended up changing the password, which would have been much easier in the first place. It's strange how in one company the SYS passsword is guarded with one's life and at another company every other person has it Mad

Sorry for all the craziness

Also, Shaseeb for ur information .
You can get process ID from SPID column of v$process .

#complete query

select
       substr(a.spid,1,9) pid,
       substr(b.sid,1,5) sid,
       substr(b.serial#,1,5) ser#,
       substr(b.machine,1,6) box,
       substr(b.username,1,10) username,
--       b.server,
       substr(b.osuser,1,8) os_user,
       substr(b.program,1,30) program
from v$session b, v$process a
 where
b.paddr = a.addr
and type='USER'
order by spid;
