Record on block DB

Hi all

A question concerning how Oracle actually stores the recordings on disc. Let's say we have a database of 8K block, or 8192 bytes... who consider 192 bytes (just for example) are used for the header information. So we're with 8 000 bytes.

If we have a single record take 4500bytes and then fact oracle maintains the 3500bytes remains free or it allocates the same record following their breaking of blocks...

Please suggest...

Thank you

It depends on the size of the incoming next record and you use freelist management or SAMS.
Can you be more specific about the scenario that you are interested in.

  • Adding records int BLOCK in a loop

    Hi all

    I have problems in the following ways:

    When I press a button, I request a cursor that returns several records, according to certain values on this record that I have to add, or not a block.

    Somoeone please tell me how to do, I do:

    GO_BLOCK ('BLOCK');
    FOR reg cursor
    LOOP
    ..
    ..
    If s = reg.value"then
    create_record;
    : BLOCK. VALUE = S ';
    end if;
    ..
    ..
    END OF LOOP
    close the cursor;
    Exception
    while others
    close the cursor;


    THX in advance!

    The problem that I feel is the FRM-40102.

    The "FRM 40102 Records must be inserted or deleted everything first" error implies that you already have a line/record of "New" in your form so that when you call the CREATE_RECORD integrated forms you said that you have not met the minimum values required for the current 'new' recording you can not create a new.

    Frm40735 suggests (good choice of name, incidentally), rather than using the Create_Record, I would recommend that you check if the line the cursor is a new record before attempting to create a new record. Your code should look like this:

    GO_BLOCK('BLOCK');
      FOR reg in cursor
        LOOP
        ..
        ..
        if reg.value = 'S' then
          If (:system.record_status != 'NEW') THEN
            create_record;
          END IF;
        :BLOCK.VALUE = 'S';
        end if;
        ..
        ..
      END LOOP
      close cursor;
    Exception
      when others
        close cursor;

  • How to record data block details without validation data?

    Hi all.
    I have a form - forms 6i - contains three blocks of data DB1 h1 ^(form/master) ^ <-DB2 ^ (in the form of table/main/detail) ^ <-DB3 ^(tabular/detail) ^

    There are certain mandatory elements in DB1, which must be entered.
    user first enter data DB1 then go to DB2 - master DB1, DB2 in detail.
    in normal when insert us a new record in the detail data block and move the cursor to the next element form will ask for validation. I solve this problem by engaging if the status in new or modified data block, that is the problem because there are certain elements is required in DB1, so if the user leave them empty and fill the tabular data block DB3 form will commit and the requested item will be stored as null in the database.

    so, how can I save the data in DB2 and DB3 temporally to the form so that the form won't ask for validation when the cursor will move to the other element?
    If Yes, then I can do a procedure which ensure that all the necessary filed came before committing.
    Thank you

    To be very honest, I'm still confused what you want to do. But the thing in the last post asked you then read on the POST in the help of forms...

    Integrated POST

    Writes data into the form in the database, but does not perform data validation. Oracle Forms valid first form. If there are changes to publish on the database, for each block in the form of what oracle Forms written deletions, insertions and updates the database. All the data that you send to the database is committed to the database of the next COMMIT_FORM that runs when the session Runform. In addition, these data can be restored by the next CLEAR_FORM.

  • How to make a loop that records data block without having to navigate to it

    I have a form with 2 tabs. Tab_1 displays the information of the monitor and tab_2 raw_data (that the user attempts to insert/update or delete) for the monitor. The two tabs have a button 'Post production', which messages the raw_data (in tab_2) to the database. If it is an update operation, I have to check if a column_value_1 has changed from what is present in the comic book. If so, then the user should be given a warning. The warning would be appropriate if the column_value_1 for any 1 record is changed. Therefore, the comparison can be stopped after first difference. The code in the when_button_pressed trigger looks like

    go_block (raw_data());
    first record;
    loop
    If value_changed then
    v_alert: = true;
    "exit";
    end if;
    IF: SYSTEM. LAST_RECORD = "TRUE" THEN
    EXIT;
    ON THE OTHER
    NEXT_RECORD;
    END IF;
    end loop;

    If v_alert then
    display_alert;
    end if;

    This should work fine if I'm in tab_2 (which displays the block of raw_data). But if I hit the 'Post production' button tab_1, go_block (raw_data()) would go to tab_2, I do not want to make. So, how can I browse the raw_Data in tab_2 block without having to navigate to this tab?

    Prosper,

    I don't have what it is possible to loop in a block without having to navigate to it. Instead, you can navigate to the control you are calling by GO_ITEM integrated.

    Kind regards

  • Record event blocks LabVIEW if the event Type is not selected.

    Hi I think that found a possible bug in LV2011 SP1.

    -Thread a property node of event Reg on the dynamic event record Terminal of a structure of event

    -Add a case to the event

    -Click on the dynamic event

    -LV accidents

    The source code included, try adding the unspecified event and look like LV breaks down.

    BR,

    / Roger

    Hi Roger,

    I doubt it. If you first select the event in the node property and then add the event to the event, you do not get an accident (I don't have at least let me know if you do). However, if boring and annoying is when it happens, there is a simple solution to the problem, which probably means that it will not be fixed on the previous version.

  • Equium A100-147: Sonic recorder blocked under Vista

    I am told that sonic recorder is blocked due to a driver issue.
    There is no way to cure this other than the upgrade I don't want to do.
    The thing is I got rid of the sound recorder help adding / deleting thing, but I still get the message of blocked driver. I've got rid of everything to do with
    Sonic, including in the registry.

    There are still two programs in the list adding / deleting, but I can't just get rid of them. One of the programs is called "sonic coders" and I said I need a disc.
    I never had a drive and he took a left when I
    went from xp to vista. The other program is called "sonic DLA" and will simply not respond after I click on uninstall.
    Although he does not seem to have any obvious effect on the performance of the pc, it's a real pain having the message there all the time.
    Anyone got any ideas what to do?

    Thanks in advance.

    As a first step, it will be interesting to know what model of laptop you have exactly and is this laptop comes with Windows XP Home or Vista edition. And secondly, can you please tell us more about your information source? Where you got information on the Sonic Software? ;)

  • How to insulate the record insertion on a block of other blocks

    Hi all

    I am facing a problem in inserting record on several blocks. Let suppose that there are three blocks A, B and C user is inserting record in the block in the user Meanwhile jumped to block B and inserting record start here and then commit those changes. Inserting record on block B is failed due to validation on block A, where user left between the two and jumped to block B and application form for incomplete registrations. However, on the block B, all elements are validated but still ask to enter data block has.

    It is possible that if the user enter the record in the current block and forms insert record in that block and validate any changes on other blocks. I tried insert_record; integrated into the insert record but did not work. An idea to get out of this situation that I would be grateful.

    Thank you.

    A form module is treated as a single unit of work or of a single transaction. Either you save all data in it or anything. If you have a logic which must be stored separately from each other, so you should design your modules accordingly, in your case, create different form-Modules for different blocks. Everything else will only cause problems and is not the way to form of work.

  • activation and deactivation of the button in the block record multi

    Hi all
    I use
    Forms [32 bit] Version 6.0.8.24.1 (Production)
    Oracle Database 10g Release 10.2.0.1.0 - Production
    I have a multi record block each block contains a button (the button is to approve the record in terms of change of status)
    I have elements such as the date, remarks and button
    the button should be enabled if the remarks is not null in the case otherwise it should be disabled.
    I wrote to this effect in the pre-record trigger
    if :record is null then
       set_item_property('button',enabled,property_false);
    else
          set_item_property('button',enabled,property_false);
    end if;
    What problem is enable and disable has repercussions on all the buttons in the block. in other words, if the remarks of the first record is null then all records button is disabled. If the observations of the first record column is not null, then all the records in the column of buttons is enabled.
    I have to enable and disable the button for the corresponding record.that ways if the remarks of the first record column is not null not so only records first button should be activated and others should be disabled.

    Thank you...

    Hello

    but I'm not able to do.

    You can find the current record Y_POS 
    

    This means that whatever the user record navigates according to whether the button position gets her past set.but not.
    for example the user navigates up to the fourth record that will settle the position of the button but if user navigates back to the first record. the position of the button is going to the fifth record?

    V_ITEM_Y_POS: = GET_ITEM_PROPERTY ("NOM_ELEMENT", Y_POS);

    Please note that do not use the button element to get the Y_POS.
    This should be another element in the block, then button as a buttons position will continue to change on
    What you are to get the Y_POS of button which is the fourth position of the record for the first time so, it is fair,
    second time you set Y_POS button which is 4th record + first recording which is the fifth album,.
    you need to find is the Y_POS from a fixed point in the block.

    in your description what do you mean by top_record. Why I ask, is because it is multi record block(showing_10_records).so will appear every 10. no record may be hiding.

    Top of page record is the first record in the block.
    For example, in a record 10 block, if there are 20 records then if you navigate the records, if you go to the 11th, 12th, 13th, 14th... the other then your TOP_RECORD be record No 2, 3, 4,... is the first record that is displayed in the block that is not always 1, and will be 1 only for the first 10 rcords.
    If we use: system.cursor_record we will not be able to get the Y_POS exact numbers of superior record then 10 which will put the button located under the last (10th) record, which is not what we want, so need to find the TOP_RECORD.

    Best regards

  • Insert Record Server causing DWCC2015 down behaviors?

    Since the upgrade to DWCC2015 I have real problems with the server behaviors panel in that whenever I try to create a behavior to insert a record, it blocks DW.

    I had to install the Panel "Disapproved the server behaviors" to get my database, links and server panels behaviors back, but I assumed that the feature in their midst would continue to operate.

    Would be recognizing all of the advice offered because it is totally flat all my websites database!

    Thank you.

    NJ

    Obsolete means ' is no longer supported. You use them at your own risk.

    If you really need to use server behaviors, you must install Dreamweaver CS6, which is included in your subscription to creative cloud. CS6 can coexist with the latest version of the CC on the same computer. However, you cannot run both programs at the same time (at least on Windows).
