Killing Oracle Sessions

Please ignore it. By mistakely i posted this thread here.
Hi All,
I want to drop one user. If i made a attempt to drop that user, I rec'd "ORA-01940: cannot drop a user that is currently connected." error. So I checked with sessions with the username. No one is using this user. But it resists some inactive sessions.
SQL> DROP USER test cascade;
DROP USER test cascade
ERROR at line 1:
ORA-01940: cannot drop a user that is currently connected
SQL>select sid,serial#,username,status from v$session where schemaname='TEST';
SID SERIAL# USERNAME STATUS
131 4026 TEST INACTIVE
143 29325 TEST INACTIVE
SQL> alter system kill session '131,4026' immediate;
system altered.
SQL>alter system kill session '143,29325' immediate;
system altered.
SQL> alter system kill session '131,4026' immediate;
system altered.
SQL>alter system kill session '143,29325' immediate;
system altered.
SQL> alter system kill session '131,4026' immediate;

system altered.
SQL> alter system kill session '131,4026' immediate;
system altered.
SQL>alter system kill session '143,29325' immediate;
system altered.
Now. I checked in v$sessions,
SQL>select sid,serial#,username,status from v$session where schemaname='TEST';
SID SERIAL# USERNAME STATUS
139 12982 AGILITY_QA INACTIVE
141 54482 AGILITY_QA INACTIVE
It shows some other inactive sessions. so i am trying to kill these 2 sessions again some inactive sessions will show.
Please assist me to fix that problem.

Try the output of the query to kill all sessions:
select 'alter system kill session '''||sid||','||'4026''' immediate;' scr
from v$session
where schemaname='TEST' and status <> 'KILLED'

Clear the entry for killed/sniped session in v$session

Dear all,
In our production database(11.2.0.1.0) running on windows 2008 server many client session showing inactive from last 4-5 hour and I want to kill those session because all sessions are dedicated so for this I created a resource plan set its idle time after certain interval session status is showing killed but it is not removing entries from v$session but our client demand is it must be clear from v$session so for this i was using DOS command taskkill utility to kill particular os process so I want to know what is the smartest way to do this.

This is known behavior, not an issue.
In a dedicated server environment when the session is killed and the rollback completes the process goes away so a join between v$session and v$process will fail. The v$session entry also usually goes away rather quickly, though I have seen cases where the v$session entry hung around till the instance was bounced. But normally Oracle will overlay the v$session entry with a new session using the same sid but a different serial# within seconds on a busy system.

Metalink doc id 1023442.6 is also something confirming it.

So, what is best in this regard :
ALTER SYSTEM DISCONNECT SESSION
The ALTER SYSTEM DISCONNECT SESSION syntax is an alternative method for killing Oracle sessions. Unlike the KILL SESSION command which asks the session to kill itself, the DISCONNECT SESSION command kills the dedicated server process (or virtual circuit when using Shared Sever), which is equivalent to killing the server process from the operating system. The basic syntax is similar to the KILL SESSION command with the addition of the POST_TRANSACTION clause. The SID and SERIAL# values of the relevant session can be substituted into one of the following statements.
SQL> ALTER SYSTEM DISCONNECT SESSION 'sid,serial#' POST_TRANSACTION;
SQL> ALTER SYSTEM DISCONNECT SESSION 'sid,serial#' IMMEDIATE;

How to kill concurrent request oracle session which is terminated

Dear,
In our production environment Concurrent request "Gather Schema Stats" was running 2 days. Hence we cancelled the request.
Request completed as terminated status. Unfortunately the oracle session of that concurrent request went to "Killed" status. Still utilizing CPU resource.
If we try, "alter system kill session 'SID,serial#';"
it gives below message,
ERROR at line 1:
ORA-00031: session marked for kill
Could you please provide steps to kill this oracle session.

Killing a oracle session

Do not confuse between deadlock and hang.

Kill all oracle session

Situation:
Oracle Forms 9i application, with multiple oracle forms (MDI). When I call a new forms I use OPEN_FORM(v_cm_module, ACTIVATE, session, pl_id) so I create a new oracle session.
Problem:
The user open a lot of windows (oracle forms .fmx with diferent sessions each one) in the oracle forms application, when they close the browser window (X botom of the browser, mozilla, internet explorer), the session are still alive (only kill one session....the first I think).
I know that after 15 minutes oracle kill the rest of the sessions, but if the user was editing a block (locking a record), and close the browser, the table still lock 15 minutes!!!!.
Any sugestions:???
Thanks

Is it necessary to create a session for each form?
If so you could do the following:
in the formsweb.cfg set the seperateframe property on true; and place some JavaScript code into the htmlafterform property:
HTMLafterForm=<script type="text/javascript"> window.moveTo(-10000, -10000); </script>
now you have a seperate frame, the browser window gets moved to a position where you can't see it ;-). when clicking the X button in the seperate frame the current form will be closed; your MDI application is still running...if you wan't you can write a JavaBean, and get the windowlisteners of the seperate frame and replace them with your own...of course you can close the Browser by right clicking and closing it in the taskbar; but that's a thing you must live with...
besides that I have no clue how to get rid of those sessions, as I don't you have any event you can act with when closing the Browser. But if so you could save every sid in every when-new-form-instance trigger (you can get it from v$mystat), and when this event occurs you could kill all those sessions (alter system kill session ....) ;-). but as far as I know that's not possible...

Killing all sessions at once who are locking the objects

Hello all,
i am working in 9i Oracle RDBMS on AIX IBM OS
most of the time we face locking issue and there comes more then different 50 sessions which locking different tables.
here is my script to find out what sessions are locking what tables.
set lines 200
set pages 50000
col SID for 99999
col SERIAL# for 999999
col username format a12
col sql format a55
col event format a50
col program format a40
col MINS for 9999
col ID1 for 999999
col object_name for a35
col locktype for a8;
select /*+ ORDERED */ s.sid,s.serial#,s.status,round(s.last_call_et/60) MINS,s.program,l.ID1,d.object_name,d.object_type,l.type as locktype
from v$lock l,v$session s, dba_objects d
where l.sid = s.sid
and l.ID1 = d.object_id
and s.username = 'MULDMS'
and last_call_et > 120 and l.type <> 'TX' order by s.status,MINS,l.ID1,l.type; and the out put it gives something like

Karthick's script will 'kill' the sessions but before you use that script you may want to read the docs about the KILL and DISCONNECT clauses.
See the DISCONNECT SESSION and KILL SESSION clauses in the SQL Language doc
http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_2013.htm#sthref4724
>
DISCONNECT SESSION Clause
Use the DISCONNECT SESSION clause to disconnect the current session by destroying the dedicated server process (or virtual circuit if the connection was made by way of a Shared Sever).
The IMMEDIATE setting disconnects the session and recovers the entire session state immediately, without waiting for ongoing transactions to complete.
KILL SESSION Clause
The KILL SESSION clause lets you mark a session as terminated, roll back ongoing transactions, release all session locks, and partially recover session resources.
IMMEDIATE Specify IMMEDIATE to instruct Oracle Database to roll back ongoing transactions, release all session locks, recover the entire session state, and return control to you immediately.
>
For DISCONNECT the IMMEDIATE clause will recover the session state 'immediately'.
Using KILL, even with the IMMEDIATE clause, you are telliing Oracle to roll back any ongoing transactions and that can take a lot of time.
Make sure you are really doing the operation you want to do. If you want to get the locks released immediately you need to use 'DISCONNECT IMMEDIATE'.

Old Oracle Session with Tomcat is not kiiling automatically

Hi,
I am facing a problem of increasing inactive oracle sessions with tomcat, Old Oracle sessions with tomcat are visible with new one.
if somebaody did not restarted tomcat gracefully, then does Oracle keep the session connected or is there any way that whenever any one restarted tomcat abnormally, Oracle session can be killed.
I had restart the database to kill session.

Could you please tell me that where do i set this parameter in parameter file or sql net file and what is the recommended value, do you have any document on this.
Another thing tomcat is in other server machine and my database is in different server machine, killing process in tomcat server machine manually may not kill linux process on oracle database machine and therefore oracle sessions are still there.
Is it possible?

Killing User sessions and user calcs

Hi all,
We have a situation where users run their business rules during evening and at times in night.
We also have a maxl script which does aggregation and other calcs daily in night and it does not run as other calcs are launched by users.
Is it possible to kill the user session and calcs launched by users before running maxl calculation for consolidations?
I know I can do in in EAS, but want to try to do it in MAxL for automation.
Thanks in advance

You would be better off locking people out. After you kick off the automated calc, killing sessions doesn't stop them from initiating calcs while your automated calc is running. In answer to your question, yes, you can do that in maxl.
alter system kill request all;
You have other options if you want to be more selective on what you kill.
kill request <session-id>
kill request by user
kill request on application
kill request on database
Check out the technical documentation for more info - http://docs.oracle.com/cd/E17236_01/epm.1112/esb_tech_ref/launch.html.

Java hibernate oracle sessions never get closed

Hi all,
I'm opening some Oracle sessions from a java-hibernate app. When a shutdown my java-hibernate the oracle sessions remain opened, even if the java process is not seen as running with "ps -fea | grep java".
The problem is that this oracle sessions never die, they remain there and the only way to kill them is to either manually kill oracle process, or to restart the oracle instance or to restart the unix box where oracle resides.
My java/hibernate app always close the session with a final statement in the source code, no matter what.
Thanks in advanced.

Hello,
In fact you may use orakill it's an Oracle utility for Windows so as to Kill the thread corresponding
to the session.
It's equivalent to a kill -9 on Unix.
Please find here a link about the use of orakill:
http://articles.techrepublic.com.com/5100-10878_11-5224960.html
Hope this help.
Best regards,

AUTOMATICALLY KILL INACTIVE SESSIONS

Hi all. we are using oracle 8.1.6 on windows-2000 with 2gb ram. we facing
ora-12500 listner failed to start a dedicated server.
error and for this we made certain changes. we also added a parameter in sqlnet.ora at server side sqlnet.expire_time=10.. for automatically killing inactive sessions but it did not helped and many sessions remain in v$session. i wana know what should we do to kill inactive sessions. because i think when the sessions reach more than 300 then we face problem of listner failed. thanks for u'r valueable comments in advance as well.
best wishes

Hi Nicolas, what you say is correct, but, unless the user try to do something (and receives an error),
those sessions will show up as SNIPED in V$SESSION, and never go away.
We can create a procedure to kill these sessions, something like this : 1 CREATE OR REPLACE PROCEDURE Kill_Sessions   IS
2      Stmt           VARCHAR2(200);
3      V_Sid          VARCHAR2(30);
4      V_Serial       VARCHAR2(30);
5      V_Username     VARCHAR2(30);
6      CURSOR pri IS
7      SELECT Sid, Serial#, Username
8      FROM V$Session
9      WHERE Username Is Not Null
10      And Username not like 'SYS%'
11      And Status = 'SNIPED';
12 BEGIN
13      FOR usr in pri LOOP
14      V_Sid     := usr.Sid;
15      V_Serial := Usr.Serial#;
16      Stmt      := 'ALTER SYSTEM KILL SESSION ''' || V_Sid || ',' || V_Serial || '''';
17      Execute Immediate(Stmt);
18      END LOOP;
19* END;
20 / and execute it every minute (change 1440 to change the frequence) :SQL> Declare
2     Out_Var Int;
3 Begin
4     Dbms_Job.Submit(Out_Var,
5     'Kill_Sessions;',
6     Sysdate,
7     'Sysdate+1/1440' );
8* End;
SQL> /
PL/SQL procedure successfully completed.
SQL> commit;

How to kill the session after the user exit the ADF application

Dear all
I have a problem
The problem is the session still exist after the user close the application and the browser. I want to kill all sessions that is not active.
This is my test scenario:
1- I open IE and run my ADF application that is deployed on weblogic. http://192.168.100.17:7001/myapp/faces/login
2- At the same time I issue this SQL command to view the sessions for user 'ADFUSER' - the "ADFUSER" is the schema user.
SELECT USERNAME,STATUS FROM v$session
WHERE USERNAME = 'ADFUSER';QUERY RESULT IS
USERNAME                       MODULE                                           STATUS
ADFUSER                         JDBC Thin Client                                 INACTIVE3- Now the user close the browser
4- Run the SQL again and I notice that the session still exist
SELECT USERNAME,STATUS FROM v$session
WHERE USERNAME = 'ADFUSER'RESULT:
USERNAME                       MODULE                                           STATUS
ADFUSER                        JDBC Thin Client                                 INACTIVE5- now the user open the URL again http://192.168.100.17:7001/myapp/faces/login
6-Run the SQL again , and I notice that the old session still exists and a new session created too.
SELECT USERNAME,STATUS FROM v$session
WHERE USERNAME = 'ADFUSER'RESULT:
USERNAME                       MODULE                                           STATUS
ADFUSER                        JDBC Thin Client                                 INACTIVE
ADFUSER                        JDBC Thin Client                                 INACTIVE
2 rows selected.and every time I login to the application , a new session is open and the old session still exist
I do not know why this happens
I want to kill old session when the user close the application.
These sessions are cleared only when i restart the weblogic domain.
here is some information about my development environment:
Jdeveloper 11.1.2.3
WebLogic Server Version: 10.3.5.0
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
thanks in advance

Hi,
for performance reasons you should not use dedicated user connections to the database. Instead you use JDBC data sources (default in JDeveloper for ADF BC) that you can configure the database connection pooling for. This means that your v$session will always show a set of active session, which however are shared among users. Assuming you use ADF BC, this is what happens
- A user requests a data bound page
- The ADF BC checks out an AM and connects to the database using one of the database connections in the pool
... user work here ...
- user exits application
- ADF BC returns AM to pool and passivates pending user state (if application is left with dirty transaction)
- Database connection is available in pool as soon as AM released
This also happens between requests. Long story cut short: v$session doesn't give you a true picture

ok fine but how to search for lock session and client IP?
i want when session lock and i want to search that session which is locked and want to kill that session?
how?Okay, search session which are locked you can by why you want to know the client IP?
For check the locked session with session id and serial# here is the query.
select substr ( o.owner || '.' || o.OBJECT_NAME, 1, 32 ) "LOCKED",
substr ( l.oracle_username, 1, 20 ) ouser,
'''' || substr ( l.session_id || ',' || s.serial#, 1, 12 ) || '''' sid
from sys.dba_objects o,
sys.V_$LOCKED_OBJECT l,
v$session s
where o.OBJECT_ID = l.OBJECT_ID
and s.username = l.oracle_username
and s.sid = l.session_id;But before executing this make sure that user can access v$session.
Normally form does not allow to use data dictionary view in forms. So, you can use as a view in form for the above query.
Do you have any Module?Why? it is better to work from start and learn more instead of getting something ready.
-Ammadbe aware to automate this process.... when user updates any data and stay on the record this view will give you that table is lock also database will show that session is active.
