• How to check whether or not the value is already in the collection

  Hello
  
  I'm in the analysis of a donkey of xml file assigning values to the collection.
  For each new record, that I am available for capture of xml, I need to check if this value already exists in the collection or not, and then only I must add this value to the collection.
  How we do that. I am not able to check whether or not it is already present in the collection. Help, please.
  
  Here is my code
  
  
  TYPE tab_A_type_rec IS RECORD)
  Name Varchar2 (50);
  );
  
  TYPE tab_A_type IS TABLE OF THE tab_A_type_rec;
  
  pkv_A_tab tab_A_type: = tab_A_type ();
  
  
  l_nl: = dbms_xslprocessor.selectnodes (dbms_xmldom.makeNode (l_doc), ' / / List "");
  for cur_rec in 0... dbms_xmldom.GetLength (l_nl)-1 LOOP
  l_n: = dbms_xmldom.item (l_nl, cur_rec);
  
  pkv_A_tab.extend; -----
  pkv_A_tab (pkv_A_tab. (Last). Name: = dbms_xslprocessor.valueOf (l_n,'Name / text () '); -I have to do these two steps only after checking whther that value is already present in the collection pkv_A_tab or not... What will be the stated case.
  
  end loop;
  
  
  Thank you

  The only problem - cannot use SET operator nested table records ;) or even on a table nested objects, unless the object type has map/delivery orders. Now if in real life, record type has only one attribute - NAME OP can just create type of TABLE OF VARCHAR2 (50). Then:

    2      type tab_A_type is table of varchar2(50);
    3      pkv_A_tab tab_A_type := tab_A_type('A','B','C','A','B','C','D');
    4  begin
    5  if 'B' member of pkv_A_tab
    6    then
    7      dbms_output.put_line('Found B.');
    8  end if;
    9  pkv_A_tab := set(pkv_A_tab);
   10  dbms_output.put_line('List of distinct elements:');
   11  for i in 1..pkv_A_tab.count loop

• How to check whether or not the arraycollection collection is initialized

  Hi all

  I am bit new to use the collection arraycollection in flex. I'm having this particular scenario, where I get Server data in a table. So I have to check if the arracollection I created is initialized or not. If it is not initialized I need to initialize it or other wise, just add collection from table to table. Here is the code snippet

  currentTrajectory = new collection ArrayCollection (event.result as Array);

  var _multiTrajectoryEvent:MultiTrajectoriesEvent;

  _multiTrajectoryEvent = new MultiTrajectoriesEvent (MultiTrajectoriesEvent.DRAW_AUTO_TRAJ);

  If (!) (_multiTrajectoryEvent.trajectories.source is nothing))

  {

  _multiTrajectoryEvent.trajectories.addItem (currentTrajectory);

  }

  else

  {

  _multiTrajectoryEvent.trajectories = new ArrayCollection ([currentTrajectory]);

  }

  But unfortunately the above code does not work for me, because the arraycollection collection is not initialized first, there is no way of checking me if it is initialized later or not as the compiler gives me the error checking to null...

  Can any Walter suggest how can I check if the table collection is initialized or not?

  I would appreciate any suggestions and thouhgts for the same

  Thank you

  Akshay

  Sorry to say, but it's not the right approach...

  I'm abt don't know what is exactly done so I'll give a generic example...

  I have an ArrayCollection collection...

  private var arrC:ArrayCollection;

  Maybe it's getting used internally in several places, so you be sure if she be initialized already or not. Then use a code something like that...

  If (arrC! = null & arrC.length > 0)

  {

  ...

  ...

  }

  If you are using

  If (arrC.Length > 0)

  {

  ...

  ...

  }

  and it is not initialised it will give exceptional at the time to compile...

  For a logic if(a && b) be true both a and b must be true, so if same first one (a) is false it will not evaluate the second logic (b).

  Thus, the previous logic works.

• check whether or not a concurrent request is complete the backend

  Hi all
  I want to check whether or not the competing applications is complete the backend using the API. I discovered that FND_CONCURRENT.wait_for_request can be used, but inside this procedure they use dbms_lock.sleep command to delay treatment. I used the same dbms_lock.sleep in my code, but does not correct results.
  Please you siggest me on solutions workaround that needs to be done to get the exact time of the concurrent request will have to fill.
  
  
  Thank you and best regards,
  Mahesh

  Hello

  You can get the same information in table FND_CONCURRENT_REQUESTS (API of FND_CONCURRENT of the readings of the same table).

  If you want to continue to use an API, see if you can use FND_CONCURRENT. GET_REQUEST_STATUS (Please check if it is a public API).

• How to check generating a lot of archivelogs/session of the user?

  Hello
  
  On a 10g database, how can I get to the session/user who generates a lot of archivelogs?
  
  Thanks in advance,

  For the currently connected sessions, you can query V$ SESSTAT (join to V$ STATNAME). Therefore,.

  select s.sid, s.value
  from v$sesstat s, v$statname n
  where s.statistic#=n.statistic#
  and n.name = 'redo size'
  order by 2
  /
  

  However, there are few complications:
  1. persistent Sessions will appear with very high statistics, simply because they have not disconnected. Many applications maintain permanent Sessions for one of
  a. follow-up and ongoing execution user submitted or jobs at the request (for example, in Oracle e-Business Suite and Peoplesoft)
  b. connection pooling
  2. the Sessions that have already disconnected will not appear in your report.

  Therefore, you have to frequent meetings of "sample" and find that the differentials redo size. Then, another complication hits you:
  c. oracle reuses the Session ID. Once a session disconnects, another session of connection can get the same SID. He could get the same serial number immediately, so you might want to use a combination of SID + SERIAL # from V$ SESSION as your key (you will need to add V$ SESSION in your query of surveillance) even in this case, I would not ensure that the couple would not repeat after some time, especially with the restart of the instance.
  You would be better to use AUDSID from V$ SESSION, that this value is incremented (and not reused) auditing session.

• I'm on disk check utility, how do I know when its done and how I know whether or not, I have a problem?

  I have Microsoft windows, I have a laptop, windows vista, I ran CCleaner, Speedy PC Pro, Uniblue registry Booster and security system from Microsoft that comes with this system. Now, whenever I run these or any program on my computer that has to do with safety or clean my computer or any fixing problem, I get a message that appears from the bar saying run disk utility to check off tasks? I know you probably want to know what the message says, but I can tell you that he keeps telling to run check disk utility.  the full message is "corrupt Registry Booster.exe file or directoryc:\program key is damaged and unreadable. Run the chkdsk utility.  What can I do to fix this?

  ... Initially re-read your error message.
  ...." Corrupt Registry Booster.exe file the file or the directoryc:\program

  data\microsoft\crypto\RSA\machine keys is damaged and unreadable.

  Your registry booster has damaged your system.

  Uninstall Speedy PC Pro and Uniblue Registry Booster. They is snake at best, disastrous at worst oil.

  As the CCleaner, it's ok as LONG as stay you away from registry option in the left column. Never use registry cleaner... period.
  Registry cleaner could be useful in the hands of accomplished computer experts.
  In the hands of regular users, it's a time bomb.

  You said... more security system from Microsoft that comes with this system.
  Only the security system that comes with the operating system is Windows Defender and Windows Firewall.
  This is not enough. Advise to install Microsoft Security Essentials...
  It's a free program and good enough for home use.
  A point to note: stop Windows Defender because he has his own Defender. 2 defenders running on the same computer will create conflicts. It's normal.

  How long disk check run...

  Depending on your system. More "junks" in the system, more time. In general, it takes some time. When it runs, don't interrupt, don't stop the computer.

  How do you know you have a problem or drive no check...

  The system will create a log of disk check. Here's how to access the Journal:

  Start > in the search box, type event viewer > Enter >
  the column on the left, click on the pointer before Windows logs
  Select (left-click) Applications, and then
  Click with the right button on Applications
  Select search
  in the 'search box', type chkdsk
  Click next
  leave the search window
  the middle column, you will see Wininit 1001, click
  right column, under the event 1001, Wininit, click Properties of the event
  A new window with the diskcheck newspaper.
  You can use the slider to display, or click the button copy and then paste it to the one that you want to use, such as Notepad or wordpad.

• How canI force FF DO NOT reload old session after crash/reboot the PC?

  My PC has problems and crashes. This isn't a problem with FF BUT: cause me this problem in FF: after reboot, when I restart FF he tries to recharge old session, EVEN if my options are set to 'Show my home page' and NOT 'my windows/tabs from last time '. When he tries to restore the tabs, FF, it causes my PC to hang & crash AGAIN! How can I force FF again, as if I could close healthy? Maybe a way to launch FF in 'safe mode', sort of? Thank you! -Marvie

  The value of the integer pref browser.sessionstore.max_resumed_crashes to 0 on the subject: config page in order to get the about: sessionrestore page immediately with the first reboot after a failure has occurred or the Task Manager was used for the closing of Firefox.

• Check the permissions of a user session

  I have a problem with a supplier 3rd party application

  The application is very poor (this requires access s/n)

  I believe that the application performs the following operations when a user connects

  User1 create a session

  It's round fires a trigger or procedure (I can't see the code for as it is encrypted)

  The trigger allows User1 a tas bunch of roles, then runs the sql statement in the User1 and him revokes roles (even if the declaration of the User1 is still ongoing)

  Sometimes the the User1 sql statement can take a few hours to run

  During this time, it is possible to check what are the roles granted to the session of the User1?

  I think at one of the tables $ x will have the answer

  This is a Dev env and there is nothing in the dba_audit_trail

  The REDO logs will have all THE statements that have been executed.
