• It is safe to kill idle session?

  Hello
  Recently working on the production environment I've met customer number of connection problem as follows
  
  sqlplus username/password
  
  SQL * more: release 9.2.0.4.0 - Production Wed Feb 25 15:46:31 2004
  
  Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.
  
  ERROR:
  ORA-00020: maximum number of processes (%s) exceeded
  
  
  After trying several times I connected and identified about 250 idle sessions of the only user of view V$ session.
  I have questions about this scenario.
  
  (1) I guess that inactive session consume processes, that triggered this error. Please correct me if I'm wrong.
  (2) is it safe to kill these idle without the approval of customers sessions because their status says they are 'INACTIVE '?
  (3) if not then, when idle, do these sessions are certain activities of long durations and because of their laziness oracle mark as inactive?
  
  My apologies for being naïve... :) Thanks in advance...

  Yes - in a perspective of database instance. Oracle is very robust. It does not choke when a user session suddenly disappear.

  Course from the point of view of the customer? Not really. The client may always require this session - it may even have a unique transaction to validate.

  From a point of view s/n? Joy. Let me count the ways of contentment by waving the old lead pipe and killing sessions... ;-)

  (3) if not then, when idle, do these sessions are certain activities of long durations and because of their laziness oracle mark as inactive?

  You can watch the session $ v and that there should be a column that contains the current state of waiting for event time / elapsed (take a look at the Oracle Reference guide). If this wait state is SQL * Net client message or similar and the wait state has quite a long time (you set this number), then it would be wrong to kill the session in order to allow new.

  Another option is looking at shared server sessions. Here is the light weight in comparison to the server by default. For example a sessions 100 user may be services by 2 dispatchers and 10 shared - server process that oppose an almost 10 x more charge of a 100 process heavy process.

• kill notched sessions

  is it necessary to explicitly kill sessions marked as "SNIPED"?
  
  I put in the profile for idle less than 2 minutes limit.
  
  After that, the session time is sniped, but rest in GV$ SESSION
  
  as the behaviour is - she gets removed from GV$ SESSION when the user try to access again
  
  but users do not connect through sqlplus,
  
  
  also the number of notched sessions will affect the total number of sessions allowed (sessions parameter)
  instance, and give maximum sessions exceeded error?

  Check this note in metalink:
  DOC - ID: 96170.1

  Apparently this note says that Yes, you must explicitly kill them.

  Based on the documentation:

  [SNIPED - Session inactive, waiting on customer | http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2088.htm#REFRN30223]

  So I'll wait until they count the sessions and you may have an error on the maximum number of open sessions.

• Who killed my session and when?

  Hi gurus,
  
  Could you tell me how can I check which killed my session and when two days before? Which table should I interview?
  
  Any input will be appreciated.
  
  
  Thank you.

  You can't unless you have auditing enabled for ALTER SYSTEM.

  Which table should I interview?

  There is no table to the query, unless you already had the above verification enabled. In this case, see SYS. AUD$.

  Hope that helps,

• How to kill a session by the non privileged user

  Hello
  
  I use the oracle 10.2.0.3 version.
  
  I have to give privileged kill session to a user non-preferred, below 2 ways, I know that this can be done with.
  
  1. by giving change the system to this user privilege.
  
  2. by creating a procedure in any user with DBA privileges, which has the statement to execute immediate change the system kill session & by granting execute this procedure to this user.
  
  Apart from the above two ways, I heard that there is a procedure/priviledge etc. also well integrated into Oracle. Which can be granted to individual users.
  
  No idea if there is something of this kind?
  
  
  Thanks in advance.
  
  Best regards
  Oratest

  Each session has a partner gets server process created in OS that Oracle creates (the setting of the dedicated server), so if you kill even the session in Oracle and the corresponding operating system process is not killed, then the session is marked for KILL and do not get killed instantly or marked as snipped.

  Also, there is no explicit privilege in Oracle to grant only the ability to kill session, you will need to ALTER SYSTEM privilege and, of course, it gives you much more capacity than to simply kill the session and therefore impossible to give all users who does not keep a database.

  Your only option is to go to the Task Manager/Unix command line and kill the ESSSVR.exe process. This process is blocked and all of the demolitions that you issue of EAS/MaxL won't fix.

• Kill the Session procedure file

  I want to develop a process where the user can shoot session by themselves.

  Currently I use the following script to kill all idle sessions.

  If I try to create a procedure and pass in the form, it gives me an error

  EXECUTE IMMEDIATE does not work.

  Set serveroutput on

  Dear SPathak ,

  Try to add IMMEDIATE too in the KILL statement. So the code will be

  declare
       sqlStmt VARCHAR2(1000);
  BEGIN
       For x in (SELECT SID,SERIAL# FROM V$SESSION WHERE STATUS='INACTIVE' AND last_call_et > 300) loop
            sqlStmt := 'ALTER SYSTEM KILL SESSION ''' || X.SId || ',' || X.Serial# || ''' IMMEDIATE' ;
            dbms_output.put_line( sqlStmt );
            EXECUTE IMMEDIATE sqlStmt;
       End loop;
  end;

• Size of session causing Oracle ADF viewScope bloat

  I'm sure you know, ADF introduced some additional scopes (pageFlowScope, viewScope and backingBeanScope) on top of the standard JSF ones. Our use of one of the stretches of the ADF, viewScope, seems to be the cause of the size of our session to swell over time.
  
  Objects that are view scope (for example, our Backing Beans) are managed by the ADF and seem to be put in the session in an org.apache.myfaces.trinidadinternal.application.StateManagerImpl object $PageState. The number of these objects when the session is equal to the org.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS in our web.xml configuration file.
  
  Once all the chips are 'used', sailing around the application, one of these objects is removed from the session and (should be) garbage collected at some point. However, the recovery of this space is observed much later, after the end of the session. For this reason, what a load of test the application, we see the use of heap space gradually, increasing before causing the JVM to crash.
  
  Tracking the creation and destruction of our objects is done by adding instructions log in the default constructor and the finalize method (which overrides the finalize on object method). Statements by logging on the creation of objects are visible when we would expect them, but logging of the finalize method statements are seen only after the end of the session. When a garbage collection is triggered using Mission JRocket Oracle control we see the use of heap down significantly, but observe no logging calls the finalize method.
  
  Anyone got any ideas on why the garbage collector would not be able to recover items from sight after having been removed from the session?
  
  Thanks in advance.
  
  P.S. I found already VIEW SCOPE IS NOT RELEASE PROPERLY in ADF which is a closesly related thread, but unfortunately could not use the answers there to solve our problem. I also posted this same question on Stack Overflow (http://stackoverflow.com/questions/13380151/lifetime-of-view-scoped-objects-oracle-adf). I'll try and update the two sons if I find a solution.

  Hello

  I tried to reproduce the problem on JDeveloper 11 GR 2 (11.1.2.3), but after 5 minutes to go back and hard, my server does not crash. However, I did some changes to your code. You can try to replicate using the following minor change?

  Instead of
  / * Method to redirect to page two. */
  Public Sub goToPageTwo()
  {
  VR;
  {
  FacesContext.getCurrentInstance ().getExternalContext.redirect ("pageTwo.jspx");
  }
  catch (IOException e)
  {
  e.printStackTrace ();
  }
  }

  I changed it to
  public String button_action() {}
  Return "goPage1";
  }

  where "goPage1" is a case of control flow, I set on my taskflow boundless.

  Thank you
