Kill inactiv session and process automatically

Hello!
I have made a JSP (JavaServerPages) Application witch can made a connection to a oracle database. Wenn I open the connection the database generates a new process and makes a session.
Now, I have the problem, when I never close the connection, the session and the process are still alive but inactiv.
How can I automatically kill sessions and the appropriate process after a time?

Sorry, but it doesnt work. I have set sqlnet.expire_time=60, to keep alive the connection for one hour. But now I found a lot of sessions witch are inactiv and where the last SQl-quere was more than one hour...
any other idea?

Kill a session and release all locks immediatly

Hi,
How to kill a session and release all locks immediately.
Thank you
AK

> Actually I am working on development envrionment (Not
production) with oracle 10g DB. What heppened is that
I needed to replace a stored DB Package, but I
couldn't even when I am the only connected user.
A read lock is placed on data dictionary objects when used - that prevents someone else from changing that data dictionary object and in effect pull the carpet from beneath the feet of the process using that object.
When trying to replace a package, it will fail if another session is busy using that package.
As for being the only user on the database and still running into this problem - there could have been a DBMS_JOB executing that package.
> I killed all sessions, and even next day still the
locks are there from a session I killed 1 day
before!
Unusual. But a killed session can take 24+ hours to rollback. A rollback is often a lot more time consuming than the elapsed run-time of the session at the time it was killed.
Back with Oracle 8i and prior, it was not uncommon to see a killed session lingering forever until the instance was bounced. But I have not yet seen this in 10G.
Suggest that when you run into this situation again, you monitor the killed session to determine just what it is doing (looking at its current wait states and events) - and whether it is indeed hanging and not releasing any locks that should have been released.

Difference between connection, session and process

Hi all,
Can anyone please update me on the difference between connection,session and process.
Thanks in advance,
- Sri

I got this useful note by googled in net. It describes session,connection,process gracefully.
A connection is a physical circuit between you and the database.A connection
might be one of many types -- most popular begin DEDICATED server and SHARED
server. Zero, one or more sessions may be established over a given connection
to the database as show above with sqlplus. A process will be used by a session
to execute statements. Sometimes there is a one to one relationship between
CONNECTION->SESSION->PROCESS (eg: a normal dedicated server connection).
Sometimes there is a one to many from connection to sessions (eg: like
autotrace, one connection, two sessions, one process). A process does not have
to be dedicated to a specific connection or session however, for example when
using shared server (MTS), your SESSION will grab a process from a pool of
processes in order to execute a statement. When the call is over, that process
is released back to the pool of processes.

Parameters session and process

How to set session and process parameters to more 500 connections...?
Oracle10g R2 Standard Edition
Windows 2003 Server R2
6GB RAM

Windows 2003 Enterprise Edition 32bitSince it's the Enterprise edition, the os can "see" and use all the RAM. Fine.
However, a 32-bit Windows means a virtual address space of 4GB (2^32) per process, split as 2:2 GB (system:user). So if you want a single process, for example oracle, to use most of available RAM, you would need to do some tweaking and testing.
Why do you need to increase the processes parameter?
What type of application is it and how is it used?

Kill session and process

Hi,
There are many answers in this forum related with my question but could not complete answer.
I have problem with process count in db. Firstly I killed sessions
alter system kill session 'xxx,yyyy';
and then queried v$session. The status of sessions were changed as killed but in v$process it showed that the count of process same as before.
So I decided to create profile and set idle time.

Hi,
When you are killing an oracle session which is created by some unix shell script you need to follow some other steps to kill that session.
When you kill a session using sid and serial# it kills only oracle session but does not frees unix process associated with that session.
To perform it correctly pls do the following.
SQL> ;
1 select s.sid, s.serial#, p.pid, p.spid, p.username
2 from   v$session s, v$process p
3 where s.paddr=p.addr
4* and    s.username='SCOTT'
SQL> /
       SID    SERIAL#        PID SPID         USERNAME

Killing user session & and update v$session

i use
alter system kill session 'sid,serial#) immediate.
user session killed but not clean, V$session show that user connect
i also want clean user session and remove form V$session
Any one who can do this ...
Thanks

Hi,
>>how remove on killing user session
As I said before, you just need to wait ... Don't worry about. On the other hand, by finding the SPID, you can force the process to be killed instead of waiting for PMON to wake up and kill it, but I think that it is not necessary.

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

At this moment, going for 9i and that too for 9207 is probably not the best thing to do. About the sizing of the SGA, there is no rule of thumb for it. If you have an idea about the work load, you may want to start with a reasonable amount like 3-4 gb and monitor it for some time in accordance with the work load. Once reached to a satisfactory level, you should check the performance of the system and try to re-adjust the values of the parameters again. Also read the below link,

Who killed my session & when?

Hi Gurus,
Could you tell me how can i check who killed my session and when two days before? Which table should i query?
Any input will appreciated.
Thank you.

Yes indeed thanks.
Some procedure like below
CREATE OR REPLACE PROCEDURE kill_session_sp
          pn_sid IN number
        , pn_serial IN number)
AS
lv_user varchar2(30);
BEGIN
SELECT username INTO lv_user FROM v$session WHERE sid = pn_sid AND serial# = pn_serial;
IF lv_user IS NOT NULL AND
    lv_user NOT IN ('SYS','SYSTEM') AND
    lv_user NOT IN (SELECT user_name from privileged_users) -- stop users kiiling System and DBA accounts
THEN
EXECUTE IMMEDIATE 'ALTER SYSTEM KILL SESSION '''||pn_sid||','||pn_serial||'''';
ELSE
RAISE_APPLICATION_ERROR(-20099,'Attempt to kill protected system session has been blocked for user '||lv_user);
END IF;
END kill_session_sp;Obviously a grant execute on that procedure should be given to someone. Normally only DBAs and production sypport may have that level of access
Why is Oracle not record the kill processes in alert log?

Procedure to kill a session

I do not have priviledge to kill the session, and i have checked the forums to create a procedure to kill the session,
so how can i use that procedure to kill the session.
Thanks

If you should be allowed to kill sessions, then your DBA will grant you the ALTER SYSTEM privilege. Or, you could request your DBA to create a stored procedure for it and then grant you execute permission on that procedure. Of course, if your DBA does not choose to do this, then this is a discussion you should be having with your management.

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
muhammad mohsin chattha

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

How to find the killed session and machine name

Hi,
At the time of batch job running .somebody killed that session .let me know how to find out the particular user name db level or oslevel .from which machine they killed how to find out at OS level . but when i have set the audit_trail=os only SYSDBA user activities are audited not the other user activities.
The server is AIX and db version 11i .provide the query for finding or os level .
thanks,
DBC.

Are you sure that somebosy had killed the session? Did you get any error regarding kill session? Is there any other errors you can see in logs?its suspect only....
>
How that job was scheduled?...actually we have lot of source systems, from those source system we are getting the data into BI machine, by using BI apps team process data and trigger load jobs @db
Apps team is having database unix logins aswell as db logins to process their requests.
Your OS admin can check the history upto some extent? Check if he has auditing enabled at OS level?we are in the process of checking with OS sysadmin.
upto now we didnt got any clue....apps team successfully re-ran failed job.

Call function RFC in a loop and kill old session

Hi,
we have a problem with a program.
here's a part of the code:
DO.
    CALL FUNCTION 'YC_REFRESH_GPT_START_CM25' STARTING NEW TASK 'TEST'
      EXPORTING
        i_profile       = p_prfl
        i_werks         = p_werks
        i_arbpl_low     = s_arbpl-low
        i_arbpl_high    = s_arbpl-high
      TABLES
        t_arbpl = it_arbpl.
    PERFORM wait_for_refresh.
    PERFORM terminate_session.
ENDDO.
So the program does a call function, waits a while, then terminates the session and recalls the function.
Apparently, like this the data should be updated.
But in the terminate session, the session is terminated using:
CALL 'ThUsrInfo' ID 'OPCODE' FIELD opcode_delete_mode
                   ID 'MODE'    FIELD l_mode.
And it works the first time, but the second time there is a dump.
So, is there another way to achieve what this program is trying to do?
Or is there another way to kill the session?
Thanks!!

Hi,
the DLL will stay in memory as long as there is a program running which has not closed (unloaded) the DLL.
Doing repetitive calls to the DLL is irrelevant in this context. LV opens the DLL as soon as needed and will only unload it when there is no VI in memory which has a CLN to that DLL...
