  Hello
  
  I have a problem to connect to my database 11.1.0.7 on linux 64.
  There have been migrated from 9.2.0.4 and everything was fine, but now I am not able to connect to the database.
  
  Go when I can connect is the startup of the database in RESTRICTED mode and I cold connection under sys (sysdba).
  
  But when I leave this mode, no one can connect.
  
  sqlplus is freezes and I have to kill this session.
  
  What could be a reason? All the settings?
  It's strange to me because he was working...

  Question for developers - how to change the module of ORACLE FORMS before logging?

  You can not set_module before logging. For an obvious reason - you are not connected :)
  You can try the workaround is to use dbms_job.submit in trigger AFTER logon.
  After 1 second, submit the procedure that will kill session if the module name is not KIKIMARA. This module time name must be already defined by shapes.
  Unfortunately no user-friendly messages in this solution...

  something like that:

  in the forms after LOGON

  dbms_application_info.set_module('KIKIMARA','');
  

  On the database:

  CREATE OR REPLACE TRIGGER AfterConnect AFTER LOGON ON DATABASE
  DECLARE
  l_job NUMBER(10);
  BEGIN
   FOR x IN (SELECT audsid
                   FROM v$session
               WHERE audsid = USERENV('SESSIONID')
               AND program = 'frmweb.exe') LOOP
         DBMS_JOB.SUBMIT(l_job, 'Audit_Kill('|| x.audsid ||');', SYSDATE+1/24/60/60);  -- 1 second
         COMMIT;
    END LOOP;
  END;
  

  CREATE OR REPLACE PROCEDURE Audit_Kill (p_audsid VARCHAR2) IS
  l_module_name VARCHAR(48);

• Two active sessions in the two tabs of the browser - how?

  Hello!
  
  I use custom for logging into my application authentication. It uses an internal table to the verification of user name and password. The rest of authentication is handled by the APEX. Here's my process of login on the login page:
  

  declare
    v_auth_successful boolean := false;
  begin
  
    v_auth_successful := pck_auth.authenticate(p_username => :P101_USERNAME,
                                               p_password => :P101_PASSWORD);
    
    if v_auth_successful then
      
      wwv_flow_custom_auth_std.post_login(
          P_UNAME       => :P101_USERNAME,
          P_PASSWORD    => :P101_PASSWORD,
          P_SESSION_ID  => v('APP_SESSION'),
          P_FLOW_PAGE   => '&APP_ID.:1'
          );
    
    else
      owa_util.redirect_url('f?p=&APP_ID.:LOGIN:&SESSION.');
    end if;
  end;

  My problem is that I can't have two active sessions of simoultaneous in two browser tabs. When I login in the app in the first tab, I can navigate fine enforcement. But as soon as I open a second tab and a newspaper in the application (with the new session ID), the first tab stopped working - I get redirected to the login page. And when I log in again, the second tab not working anymore... etc.
  
  Example can be seen here: [http://apex.oracle.com/pls/otn/f?p=47326:1 | http://apex.oracle.com/pls/otn/f?p=47326:1]-just open this link in both tabs and connect (any name of user and password will do)
  
  Someone knows how to fix this? According to me, Miss me something (in my authentication scheme?)
  
  
  Thank you

  I think that the OP's question is can this behavior be easily extended to applications that have been built in the APEX, not only the builder himself.

  This would require a sentinel of custom page common to all applications that conform to a particular session of the management rules set, regardless of those who are. The exact requirements (functional specifications) are too vague for me.

• active sessions for the global temporary table

  Hello
  
  Is there no view or the way to know how many active users evaluate a global temporary table?
  
  Rgds,
  Piyush

  The following query should list the user accounts writing (with INSERT/UPDATE/DELETE) into the temporary table 'TWG' belonged to "O":

  select s.username, l.sid
  from v$lock l, v$session s
  where l.id1 =
  (select object_id from dba_objects where owner='O' and object_name='GTT')
  and l.sid = s.sid;
  

  The following query should list all user accounts by using the temporary table named "GTT" with SELECT/INSERT/UPDATE/DELETE statement:

  select username
  from v$session s, v$access a
  where s.sid = a.sid
  and object ='GTT';

• Find the name of the database sessions via the database link

  Hello
  I have a database in which I can see a few sessions that are connected to this database of one of my server that hosts 2 databases. Now if I have queries session $ v on my local database, I can only find the host name in the column programme and module of v$ session view. How will I know what database, these sessions are established because I have two databases on the remote host, hence these sessions are estableshed.
  
  Thank you
  
  Salman

  Hello

  You can query the column process v$ session. This column contains the pid of the source database server process.

  You will find on your source machine (in your remote database of respectively two) out this pid belongs to what databases.
  If its unix, you can use (ps - ef | grep ) or if it is windows, then you can query the process $ v

• How to access the 'Active Sessions' using MBeans

  Hi all
  
  I sent a request to the EM (Enterprise Manager).
  When I have connected on EM and click on the app, I see the number of active sessions under the heading "Servlets and JSP.
  
  How can I access this setting at the application level. ??
  (I want to access this setting * 'x' * my web application and display registered users: x )
  
  EM shows that the number of active sessions. It updates too... so there must be some beans or recording for this setting...
  How can I access who...?

• Failed to refresh the database after a forced shutdown of the business rule

  Hello Experts!
  
  I am currently test and adjustment of performance of business rules in Hyperion Planning 9.3.1. I started a business rule in the Regional service Console that ran a lot too long so I decided to stop it manually. But after this manual stop when I try to refersh Essbase of Hyperion Planning (Administration > manage the database > database update) I get the following error:
  
  + com.hyperion.planning.olap.EssbaseException: impossible to restructure. There are other active users on the database [%s] (1013101).
  
  I remember having forced company rule stops earlier in other Hyperion Planning 9.3.1 deployments and they did not generate such errors. So could you help me on how to stop Hyperion Planning of this error after manual business rule stops because it's very likely I'll have do them in the future? Thank you very much!

  Are you sure he permanently stopped and everyone is out of the database, you can enter into the EAS, see view sessions.

  See you soon

• Scalability problems - too many Active Sessions?

  Hello
  
  I'm having a problem with an app that I built for one of the College campus, that I work. The application is a queue system where there are stations for students to access your room, admin stations where staff can see these students and "call", and displays outside every office employee that shows the student who was called. There are about 20 of the latter type of billboards. I have the following code in my footer to query the DB for most recent students called for a specific room:

  <script type="text/javascript">
  <!--
  var refresh_region = function( workstation_in, div_in ) {
      $.get(
          'wwv_flow.show', 
          {"p_request"      : 'APPLICATION_PROCESS=F_NEXT_STUDENT',
           "p_flow_id"      : $v('pFlowId'),      //app id
           "p_flow_step_id" : $v('pFlowStepId'),  //page id
           "p_instance"     : $v('pInstance'),    //session id
           "x01"            : workstation_in
          },
          function(data) {
              $(div_in).html(data);
          }
      );
      setTimeout(function() { refresh_region( workstation_in, div_in ) }, 5000);
  }
  
  refresh_region( '&P7_WORKSTATION_IN.', '#next_student_div' );
  //-->
  </script>

  The process of OnDemand, F_NEXT_STUDENT executes the query and returns the result:

  select a.FIRST_NAME || ' ' || a.LAST_NAME
  into   full_name
  from   ONESTOP_QUEUE a
  where  a.WORKSTATION_ID_CALLED = in_workstation_id
  and    a.STATUS = 'CALLED'
  and    a.QUEUE_ID = (
     select min( c.QUEUE_ID )
     from   ONESTOP_QUEUE c
     where  c.WORKSTATION_ID_CALLED = in_workstation_id
   and    c.STATUS = 'CALLED');

  However, when all these display panels is turned on (and I use the code as follows in the other pages for similar purposes) the application become slow and eventually unresponsive. As a first step, we have the application running a box with Oracle XE. Finally, we have migrated to a full blown installation 11g with APEX listener and GlassFish. My DBA said everything looks ok on the side of the DB, so I tried to dig into other areas to see where the bottleneck can be. After inspecting the report of Active Sessions in the APEX, I noticed that there are a ton of connections being generated (> 30 000). This is not a good thing for me and I try to understand what I am doing wrong.
  
  At first I used $. post() instead of $. get (). I was also using setInterval() instead of a setTimeout() loop. However, none of these changes really seem to help the situation. I am at a loss to know how else to improve the performance of this application. Any suggestions on what I can try?
  
  Most of the features of the app is on apex.oracle.com
  WORKSPACE: SCCC_TEST
  USER/PASS: TEST/test
  Direct URL to the page (I spend worksation ID): http://apex.oracle.com/pls/apex/f?p=65890:7:0:P7_WORKSTATION_IN:ADMISSIONS_1
  
  Thanks in advance for any help.

  Hello

  are you sure that each AJAX request generates a new APEX session? Because it is based on your downloaded app all right. You can check that by running the following query. It will also show you how long it took APEX to meet your demand for AJAX (elapsed_time). I think that the elapsed time will be the key to find out why your application becomes unresponsive if too many customers are returning. The goal should be that the AJAX request ends as soon as possible. For example 1 sec would be for many, because if you have 20 parallel AJAX requests at the same time, this could have an impact on your DB. You can share your average time?

  select apex_session_id, to_char(view_date, 'DD.MM.YYYY HH24:MI:SS') as view_date, elapsed_time, application_info
    from apex_workspace_activity_log
   where application_id = 65890
     and page_id = 7
     and view_date >= sysdate - 0.1
   order by 1, 2, 3
  

  I don't know how much data is stored in the ONESTOP_QUEUE table, but it may be useful to adjust your statement used in F_NEXT_STUDENT. On apex.oracle.com, the plan of the explain output shows at least he uses twice a scan interval on index ONESTOP_QUEUE_IDX. For inside MIN instruction it is well, but the external SQL should just do a search PK using QUEUE_ID. This is why I would like to delete

  a.WORKSTATION_ID_CALLED = in_workstation_id and a.STATUS = 'CALLED'
  

  to force the index seek PK using QUEUE_iD.

  I also suggest that you make your JavaScript code on the page 5 and 7 more transparent. He is currently hiding in the region or footer HTML. I would say to move JS code in the attributes of the page 'Function and Global Variable declaration' and ' run when Page Loads. BTW, there is no need to use $(document) .ready in "Run when the Page loads", because internally, we already use $(document) .ready.

  Or instead of using your own JavaScript code you can download the plugin http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-plug-ins-182042.html#dynamic "Timer" and use rather dynamic actions. On page 5 you can use the action "Refresh" to update your classic report and on page 7 you can use an action to "Set the value" to run your query. I think it would make your page easy to read for others.

• trace level of the user in the database.

  Hello
  
  I need emergency assistance. I wanted to take the trace of a perticular user sessions in the database. Could you please provide me with the steps to generate the trace of the user when the user connecting. In my case, when the connection of the user by the application, there are many session generated in the database. So I wanted to take the trace to the user level. I have Oracle 9i server.
  
  Thanks and greetings

  Probably the best for you would be to create a database trigger after the logon.

  CREATE OR REPLACE TRIGGER set_trace after logon on DATABASE
  BEGIN

  If the user = ('username') then
  run immediately "alter session set sql_trace = true";
  immediate ' alter events set "trace 10046 name context of session forever, level 12". "
  end if;

  WHILE OTHERS THEN
  -Consider recording the error and then re-raise
  NULL;

• Database persistence of Active Sessions does not

  Hello

  I use OAM 11 GR 2 PS2 with patch bundle 4. I just activated the persistence of the database session via the oam console, but no entry in table oam_sessions. However, there are almost 2000 Active users in the system. I also checked the oam - config.xml and the configuration is:

  < parameter name = "DB" Type = "htf:map" >

  < name of parameter = "SmeDb" Type = "htf:map" >

  < name of the parameter = "URL" Type = "xsd: String" > jdbc:oracle:thin://amdb.example.com:2001 / h < / setting >

  < name of the parameter = "Main" Type = "xsd: String" > fun < / setting >

  < name of the parameter = "Password" Type = "xsd: String" > password < / setting >

  < name of the parameter = "DataSourceName" Type = "xsd: String" > jdbc/oamds < / setting >

  < / setting >

  Should I change it manually? Or what could be the problem here?

  Concerning

  You should try to restart first and see if it will work or not and if doesn't allow is not at the level of the trace record: 32 to possibly see why you setup does not more clues about the session.
