• HP Elitebook 8560w: upgrade my ram and the correct use of slots

  Hello - my first post!

  I just bought HP 8560w refurbished seller.  It has a quad core processor and four ram slots.  I can post the SN and product number if it helps with my request.

  I want to max out my ram without disturbing the keyboard.  I currently have 4 x 4 ram installed so that four locations are used.  My machine will support a maximum of 32 of ram.

  Here is the query - I can remove the 2 ram sticks of the slots I can easily see when I remove the back (I guess these are slots 3 & 4) and replace them with 2 sticks 8 ram each?

  It would give me a total of 24 ram - 2 x 4 under the keyboard (slots 1 & 2) and 2 x 8 in two other passers-by.

  This upgrade would be OK and be recognized by the system?

  Thank you, Russ.

  Hi, Russ:

  It seems that you can according to the maintenance manual.

  http://h20628.www2.HP.com/km-ext/kmcsdirect/emr_na-c03424153-1.PDF

  He says that one of the compartment of the expansion memory slot should be filled with a chip to add a slot 2.

  It also says the same thing about the locations of primary memory under the KB.

• Question about the correct use of the WM_CONCAT

  Hello
  
  I am trying to accomplish the following:
  
  from this
  

       ENAME
       ----------
       ADAMS
       ALLEN
       BLAKE
  ...

  and ends on this
  

       OLD_NAME   NEW_NAME
       ---------- --------
       ADAMS      AADMS
       ALLEN      AELLN
       BLAKE      ABEKL
  ...

  Basically, alphabetically sort the characters within each name. I have an intermediate step that seems promising
  

  select e.ename oldname, substr(e.ename, iter.pos, 1) newcharpos
    from emp e,
         (select rownum pos from emp) iter
   where iter.pos <= length(e.ename)
   order by e.ename, substr(e.ename, iter.pos, 1);

  Yields above
  

  OLDNAME    NEWCHARPOS
  ---------- --------------------
  ADAMS      A
  ADAMS      A
  ADAMS      D
  ADAMS      M
  ADAMS      S
  ALLEN      A
  ALLEN      E
  ALLEN      L
  ALLEN      L
  ALLEN      N
  BLAKE      A
  BLAKE      B
  BLAKE      E
  BLAKE      K
  BLAKE      L
  ...

  the characters are in the right sequence, I thought that all I had to do was to use WM_CONCAT (and replace the comma it inserts with an empty string) and I would like to make. I thought it would do: (replacement of commas left out for clarity)
  

  select oldname,
         wm_concat(newcharpos) newname
    from (
          select e.ename oldname, substr(e.ename, iter.pos, 1) newcharpos
            from emp e,
                 (select rownum pos from emp) iter
           where iter.pos <= length(e.ename)
           order by e.ename, substr(e.ename, iter.pos, 1)
         )
    group by oldname;

  but the sequence of the newcharpos is messed up in the process and, rather than the expected result, I get this:
  

  OLDNAME    NEWNAME
  ---------- --------------------
  ADAMS      A,S,M,D,A
  ALLEN      A,N,L,L,E
  BLAKE      A,L,K,E,B
  ...

  My question is, how to structure the last query so that the order of character as calculated in the inner query stays?
  
  Thank you for your help,
  
  John.

• Dashboard calls between 2 different date columns

  Hi all

  I am creating a dashboard command prompt that will allow users to filter the report from 2 different date columns. We have an opening date column and a column of closing date. I want to allow users to choose an opening date and then a closing date that is at a later date. How could I go to set it up?

  Thank you in advance!

  I received your question, but I was not sure of your ability to create guest

  You will use 2 open and closed dates in the command prompt and set the variables in the presentation. In the report for this 1 date column use <= and="">= instead of operator.

• Correct use of snapshots

  Hello

  I would like to have comments about the correct way to use snapshots.

  Currently, I have a server ESXi 3.5 with 4 virtual machines.

  I use snapshots as follows:

  -J' still have 1 snapshot taken for each virtual computer

  -J' have regularly (before the size of the snapshot becomes too large) remove the snapshot and just after, take a new snapshot for each virtual machine

  -I will soon be able to make a backup of my virtual machines, but I don't now

  I recently started to monitor the size of my virtual machines, and they become several GB in just a few days.

  I wonder if it is efficient to always have a snapshot on each virtual machine.

  I'm starting to think maybe this snapshot should be taken just before to make a change on the server (installation of the software or other) to return to the State that we had before the operation, in the case where he's going poorly, then remove the snapshot after we have confirmed the operation went well, but should not exist at all times.

  Your comments are welcome! Thank you!

  Yann

  The snapshots are NOT backup anyway. If you use instant as replacement of backup then

  (1) you lose a costly storage space

  (2) that you have less reliable

  (3) you generate disk load high commit when snapshots

  What is the correct use of the snasphots:

  (1) you need to install a patch on your virtual machine

  (2) take the snapshot

  (3) install the patch

  (4) monitor behaviour of the system in case of patch broke something for awhile

  (5) commit instant if everything is ok, or go back to the snapshot if something bad happened.

• Correct use of setControllerFactory in FXMLLoader?

  Hello
  
  I'm trying to load a node FXML using my own controller using JavaFX 2.1 included in the JDK 7u4.
  All discussions point to the setControllerFactory method, but when I try to apply the code below, the plant is never called leaving the node without the controller.
  (the FXML does not set the fx:controller).
  
  I've probably missed the correct use, but I can't understand. A tip?
  

   private Node loadNodeWithCtrl(final Object instance, String fxmlPath, ResourceBundle rb) {
          URL url = this.getClass().getResource(fxmlPath);
          FXMLLoader fxmlLoader = new FXMLLoader(url, rb);
          fxmlLoader.setControllerFactory(new Callback<Class<?>, Object>() {
  
              @Override
              public Object call(Class<?> paramClass) {
                  // Never reached <<<<<<<<<<<<<<<<<<<<<<< 
                  Logger.getLogger(this.getClass().getName()).log(Level.INFO, "Using provided controller");
                  return instance;
              }
          });
     
          try {
              Node node = (Node) fxmlLoader.load();
              return node;
          } catch (IOException ex) {
              Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, null, ex);
          }
          return null;
      }

  Concerning
  
  Jean-Michel

  This is the correct behavior. Controller factories provide a way for an application to customize the construction of controllers specified via the fx:controller attribute. If you do not use fx:controller, then the controller factory will not be called.

• How better to insert a subarray (line) in a 2D array to the correct index which is based on the value of the first column

  Hello

  I would like to insert a subarray (line) in a 2D to the correct index table. The position is to say the index value depends on the value of the first column of the table 2d.

  As an examlple my 2d array would look like this

  230 50 215 255

  300 60 270 330

  360 20 350 370

  And I would like to insert another line (subarray) with the following values

  320 40 300 340

  This new line should be placed between the second and third rows (this is based on the first column only).

  I tried the threshold 1 d function table by taking an 1Dsub array of my 2d array (first column), then using the first of the new line (320) as the threshold. It sort of work, but it does not work when I start the table (IE there is only 1 row) and it seems to not work properly on other occasions (as explained in the help of Labview).

  Hopefully the explanation is clear enough for any suggestion. Thanks in advance for the help!

  JTRI wrote:

  The idea is I have start with a new table and add these lines in the right order every time that the user sets the values Jack

  Ahh, so try this.

  This will also work with an empty array.

  You want to do with this function it is a Subvi.

  Make the entries 'table' and 'subarray"on the connector, then 'new array' output.

  You can then put this Subvi in a loop with a registry to shift and it will help to add new lines in a sorted order, when they are added.

  That is what you were aiming for?

  ... If you need to take the party date to a date column and the time of anonther part, then you must first convert them to a string, concatenate them and convert them to date.

  You don't need to do this.  What you have described is a way to do it, but this isn't the only way.

  If d1 and d2 are the two DATEs, you can get year, month and day of d1 combined with hours, minutes, and seconds from d2 liike this:

  TRUNC (d1) and (d2 - TRUNC (d2))

  Nesting TO_DATE and TO_CHAR in Oracle, is almost never the best way to do anything.  Oracle provides many functions (for example, TRUNC) to manipulate dates, but also of DATE arithmetic.

• update to column values (false) in a copy of the same table with the correct values

  Database is 10gr 2 - had a situation last night where someone changed inadvertently values of column on a couple of hundred thousand records with an incorrect value first thing in the morning and never let me know later in the day. My undo retention was not large enough to create a copy of the table as it was 7 hours comes back with a "insert in table_2 select * from table_1 to timestamp...» "query, so I restored the backup previous nights to another machine and it picked up at 07:00 (just before the hour, he made the change), created a dblink since the production database and created a copy of the table of the restored database.
  
  My first thought was to simply update the table of production with the correct values of the correct copy, using something like this:
  
  
  Update mnt.workorders
  Set approvalstat = (select b.approvalstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  where exists (select *)
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  
  It wasn't the exact syntax, but you get the idea, I wanted to put the incorrect values in x columns in the tables of production with the correct values of the copy of the table of the restored backup. Anyway, it was (or seem to) works, but I look at the process through OEM it was estimated 100 + hours with full table scans, so I killed him. I found myself just inserting (copy) the lines added to the production since the table copy by doing a select statement of the production table where < col_with_datestamp > is > = 07:00, truncate the table of production, then re insert the rows from now to correct the copy.
  
  Do a post-mortem today, I replay the scenario on the copy that I restored, trying to figure out a cleaner, a quicker way to do it, if the need arise again. I went and randomly changed some values in a column number (called "comappstat") in a copy of the table of production, and then thought that I would try the following resets the values of the correct table:
  
  Update (select a.comappstat, b.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi - this is a PK column
  and a.comappstat! = b.comappstat)
  Set b.comappstat = a.comappstat
  
  Although I thought that the syntax is correct, I get an "ORA-00904: 'A'. '. ' COMAPPSTAT': invalid identifier ' to run this, I was trying to guess where the syntax was wrong here, then thought that perhaps having the subquery returns a single line would be cleaner and faster anyway, so I gave up on that and instead tried this:
  
  Update mnt.workorders_copy
  Set comappstat = (select distinct)
  a.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi
  and a.comappstat! = b.comappstat)
  where a.comappstat! = b.comappstat
  and a.workordersoi = b.workordersoi
  
  The subquery executed on its own returns a single value 9, which is the correct value of the column in the table of the prod, and I want to replace the incorrect a '12' (I've updated the copy to change the value of the column comappstat to 12 everywhere where it was 9) However when I run the query again I get this error :
  
  ERROR on line 8:
  ORA-00904: "B". "" WORKORDERSOI ": invalid identifier
  
  First of all, I don't see why the update statement does not work (it's probably obvious, but I'm not)
  
  Secondly, it is the best approach for updating a column (or columns) that are incorrect, with the columns in the same table which are correct, or is there a better way?
  
  I would sooner update the table rather than delete or truncate then re insert, as it was a trigger for insert/update I had to disable it on the notice re and truncate the table unusable a demand so I was re insert.
  
  Thank you

  Hello

  First of all, after post 79, you need to know how to format your code.

  Your last request reads as follows:

  UPDATE
    mnt.workorders_copy
  SET
    comappstat =
    (
      SELECT DISTINCT
        a.comappstat
      FROM
        mnt.workorders a
      , mnt.workorders_copy b
      WHERE
        a.workordersoi    = b.workordersoi
        AND a.comappstat != b.comappstat
    )
  WHERE
    a.comappstat      != b.comappstat
    AND a.workordersoi = b.workordersoi
  

  This will not work for several reasons:
  The sub query allows you to define a and b and outside the breakets you can't refer to a or b.
  There is no link between the mnt.workorders_copy and the the update and the request of void.

  If you do this you should have something like this:

  UPDATE
    mnt.workorders     A      -- THIS IS THE TABLE YOU WANT TO UPDATE
  SET
    A.comappstat =
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B   -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  WHERE
    EXISTS
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  

  Speed is not so good that you run the query to sub for each row in mnt.workorders
  Note it is condition in where. You need other wise, you will update the unchanged to null values.

  I wouold do it like this:

  UPDATE
    (
      SELECT
        A.workordersoi
        ,A.comappstat
        ,B.comappstat           comappstat_OLD
  
      FROM
        mnt.workorders        A      -- THIS IS THE TABLE YOU WANT TO UPDATE
        ,mnt.workorders_copy  B      -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
  
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    ) C
  
  SET
    C.comappstat = comappstat_OLD
  ;
  

  This way you can test the subquery first and know exectly what will be updated.
  This was not a sub query that is executed for each line preformance should be better.

  Kind regards

• What is the correct syntax for the use of a variable in an ad-hoc query?

  Hi all
  
  I'm a casual user of the DB and right now need to update the records about 1000 + so that a certain column gets a unique value.
  
  So I thought I'd use a variable for this.
  
  Then, I built this type of SQL statement for only a small subset of records:
  ----------
  variable number recNumber;
  exec: recNumber: = 1;
  UPDATE TABLE_TO_BE_UPD
  SET COL_TO_BE_UPD = COL_TO_BE_UPD + recNumber
  WHERE COL_TO_BE_UPD IN ('VAL_A', 'VAL_B');
  ----------
  
  I get invalid SQL statement error when you try to run above (except for the guest who asks for a value I want to omit).
  
  In any case, I also tried this one:
  ----------
  CREATE SEQUENCE seqCounter;
  UPDATE TABLE_TO_BE_UPD
  SET COL_TO_BE_UPD = COL_TO_BE_UPD + seqCounter.NEXTVAL
  WHERE COL_TO_BE_UPD IN ('VAL_A', 'VAL_B');
  ----------
  
  Of it, I got the error ORA-01722: invalid number... I guess it's because seqCounter is of type number and the COL_TO_BE_UPD is of type character... (?)
  
  Then I want to ask is what is the correct way to define and use a counter variable type to add a number at the end of a string?
  
  Also another question I would ask is that are variables that are used in queries ad hoc, also called "bind variables"?
  
  Thank you muchly

  If you want to add a unique number to a column, then it would be:

  UPDATE TABLE_TO_BE_UPD
  SET COL_TO_BE_UPD = COL_TO_BE_UPD ||to_char(rownum)
  WHERE COL_TO_BE_UPD IN ('VAL_A','VAL_B');
