Change partitioning attribute

Hi,
I have a big table partitioned by a date column (one partition for each month). I need to change the partitioning column to another date column (partitions would also be one per month). Does any one know a simple way to do that?
Database version is 11gR2.
Thanks!

You would almost certainly need to recreate the table and move all the data from the old table to the new table. You can combine or split partitions with DDL but you can't fundamentally change how partitioning is done.

  • Partition Attributes

    The Partition Attributes change from read/write to read only is there any way to monitor this in SCOM2012?

    Hi Jensen,
    According to your description, you want to get the Measure group partition process state and last processed date through DMV, right?
    As mentioned above, there is no other query other then Olaf posted. Another option for you is using SSAS AMO to programmatically get the state and last processed date time. The cube, measure group and partition classes of AMO has 2 properties that might
    helps State and Last Processed. You can refer to the link below to see more information AMO.

  • How to change the attribute name for a relation

    When the Data Modeler engineers a logical model into a relational model it create table columns for the relations. The names of the generated columns are listed in the attributes list in the properties dialog of the relation. The actual name of the attribute gets calculated by the attribute name of the entity which is part of the relation. This is okay, if there is only one relation between two entities. But when there are two relations between two entities the second attribute gets a stupid number suffix. This makes it impossible to give the attribute a useful semantic meaning.
    When I engineer the model into a relational model I can change the column name in the relational model. Changing the column name in the relational model is not perfect but it would be okay for me, if it would not be overwritten during the next engineering run.
    So I have two questions:
    How can I change the attribute name in the attributes section of the properties dialog of a relation? See here for screen shot:
    http://public.ceving.de/2012050300/relationattribute.png
    And if it is not possible:
    How can I preserve any changes on column names in the relational model during a re-engineering run?

    Hi,
    I've logged an Enhancement request on this.
    I don't believe it's possible to change it from the Entity or Relationship dialog, as it's not updatable in these dialogs.
    What you can do is change it in the Relational Model, and then reverse engineer the change back to the Logical Model.

  • How to change report attributes like heading, sort etc programmatically

    Some of the columns from a classic reports using pl/sql as region source should be sortable. Is it possible to change this attribute (sort = yes) using JavaScript or APEX API?

    Edited by: david on Sep 6, 2011 11:56 PM

    There is something I don't understand here. Why do you need to point at the sxd? What is changing? Like I mentioned before. If the contents of the xsd change, all the report will do is - at best - drop the changed fields so you will be missing data. Perhaps some of the following will help;

    Hi Manish,
    You may write the Formcalc scripting for the respective field.
    //Check ISR control parameters for read/write access
    if($record.CONTROL_PARAM.ISR_MODE == "DISPLAY" |
       $record.CONTROL_PARAM.ISR_FORM_VIEW =="ISR_APPROVE" | <b>$record.CONTROL_PARAM.ISR_REVIEW == "true" )</b>

  • How to change the attributes of GUI CONTROLS in my own program.

    hi all,
    i just want to change the attributes of GUI CONTROLS in my own program.
    for example `
    How to set an ICON on my GUI BUTTON in the program?
    so what's the mapping between CONTROL in the SCREEN PAINTER and variable in the program?

    Hi Chao Liu,
    Ya , u first find out the PF-STATUS of the screen and goto that status and now u can modify the ICON u want .
    Finding the GUI status of the screen
    Goto that  TRANSACTION CODE or SCREEN
    On the Standard Menu bar Goto ( Menu path) System --> Status
    Now u get a pop-up System :status in that in SAP Data block u can find GUI Status. Now Double Click on that Status. It takes u to the Status of that screen.
    Now click on the Display --> Change Button on the application tool bar.
    If it is a standard GUI-status then it asks for the ACCESS KEY.
    if it is a custom defined GUI Status  then u can change the status .

  • How to change the  attribute of screen field to drop down list dynamically

    Hi All,
      Col X                   Col Y
      A                        input field
      B                       drop down list
    This is a tabular disply where the Screen field attribute for Col y  is NO DROP DOWN BOX.
    My requirement is to change the attribute of COl Y to DROP DOWN list depending on the value of
      COL X  dynamically.

    Dear Ajay,
    Actually this requirement is to enhance the standard screen for Tcode :EHSVU21.
    So depending on the 1st Column(Test no)  value ,i have to change the 3rd Column(Low.norm.result)
    property either to DROP Down or not.
    So in the PBO only the changes to be made and there is no field in SCREEN internal table for changing the attribute to DROP down. I checked SCREEN internal table where the field VALUE_HELP and REQUEST is useful but not  suitable for my case.
    Any solution available?

  • .change IUCONFIG attribute value in an event-handler of IUICCON (move in)

    Hi there,
    I have been searching for over a week now both on SDN and using the debugger, hopefully this brings more luck.
    On the web-client there is this new contracts page with 3 tabs.
    On the first tab you can choose a product, select a contract and then click Configuration.
    There you can change parameters. (this is View IUCONFIG/ConfigTree) with contextnode ISUORDERITEMCONFIG.
    In this case it is not wanted that this configuration page needs to be opened.
    So I need to change the value of 1 of these attributes (always the same attribute) automatically when switching to the 2nd tab, or when clicking the save button on the last tab. Or any event on the 2nd or 3rd tab are okay. As long as they are sure to be executed in the process.
    I would prefer changing the attribute from within IUICCON/ProcessSaveButtonBar>EH_ONBT_SAVE_PROCESS
    or IUICCON/ProcessBar>EH_ONNAVTOACCOUNTDATA
    I just don't have a clue how to automatically set one value of these configuration attributes.
    Can anybody provide a solution or a workaround?
    Is there any way to change the parameters without ever going to the configuration page in the browser?
    Thanks in advance for your ideas
    Could this thread be moved to CRM webclient?

    Solved, the solution can be supplied in trade for the right amount of money

  • How do I change text attributes within one text box in Motion 3?

    I am trying to change text attributes within one text box in Motion 3, but am only able to change the font/size for the entire box. Is there a way to change the attributes to individual lines of text within a text box without creating an entirely new one or using the "Lower Third" text effect?
    How do I create (two different) multiple colors, fonts, bold, italic, underline in one text box within Final Cut Studio Motion (FCP, FCS)

    Thank you! You saved me hours of tinkering around with multiple text boxes. It seemed like it should be something pretty elementary. It didn't help that I am not familiar with proper terminology, so thank you for defining glyph.

  • How to change general attribute of text element

    hi
    who now how to change general attribute of text element on screen dinamically? I wish to change text value dinamically for example.

    Hi Denis,
    I am not too sure on what you want.
    If you require that the text value be different based on some conditions you can declare as many text elements as conditions and call the relevant text element.
    But I dont think that you can assign dynamic texts to a single text element.

  • Changing visual attribute in Enter Query mode

    Hello, I want to change visual attribute of all items in the first record when the user presses button for Enter_Query. I want that the user sees that the form is in enter query mode and it "waits" for the input of criteria. My code (copied from Help and modified) in trigger WHEN_BUTTON_PRESSED:
    DECLARE
    cur_itm VARCHAR2(80);
    cur_block VARCHAR2(80);
    BEGIN
    ENTER_QUERY;
    cur_block := :System.Cursor_Block;
    cur_itm := Get_Block_Property( cur_block, FIRST_ITEM );
    WHILE ( cur_itm IS NOT NULL ) LOOP
    cur_itm := cur_block||'.'||cur_itm;
    Set_Item_Instance_Property( cur_itm, CURRENT_RECORD, VISUAL_ATTRIBUTE,'yellow');
    cur_itm := Get_Item_Property( cur_itm, NEXTITEM );
    END LOOP;
    END;
    where yellow is the name of my visual attribute.
    The problem is that I need to press the button TWICE to color the record.
    Can anybody help me with this problem?
    Natasa

    (Wrong forum).
    The problem is that enter_query stops executing your procedure until
    another action ist started by the user.
    You must create a short-time timer before issuing enter_query and set
    your colour scheme in the when-timer-expired-trigger.

  • Change a attribute value with XSLT before importing an XML

    I need change the attribute value with XSLT before importing an XML
    <table class="x" style="width="50pt">...
    I have to divide by 200 the value of "width", and the result multiplied by 100:
    (50/200) * 100
    It's possible with a XLST?

    Hi,
    Yes you can do this via XSLT.
    You can try similar to the one below:
    <table>
       <xsl:attribute name="width">
         <xsl:value-of select="((./width) div 200)*(100)" />
       </xsl:attribute>
    </table>
    I have not tested yet... Try it....

  • Flex 3 - How to change an attribute name ?

    like this
    <item code="1" />
    to
    <item id="1" />
    thanks

    Hi Alex,
    You can use setName to change the attribute name:
    Here for example change all your id attributes with code:
    var xmlTest:XML=<r><item id="1"/></r>;
    for each (var node:XML in xmlTest.item.descendants("@id"))
    node.setName("code");
    trace(xmlTest);

    >
    First your subject asks a different question that the text you posted: Best way to change partition key on existing table. The answer to that question is YOU CAN'T. All data has to be moved to change the partition key since each partition/subpartition is in its own segment. You either create a new table or use DBMS_REDEFINITION to redefine the table online.
    Why do you want to export all data to a file first? That just adds to the time and cost of doing the op.
    What problem are you trying to use partitioning to solve? Performance? Data maintenance? For performance the appropriate partitioning key and whether to use subpartitions depends on the types of queries and the query predicates you typically use as well as the columns that may be suitable for partition keys.
    For maintenance a common method is to partition on a date by year/month/day so you can more easily load new daily/weekly/monthly data into its own partition or drop old data that no longer needs to be kept online.
    You should use a small subset of the data when testing your partitionings strategies.
    Can you do the partitioning offline in an outage window? If not then using the DBMS_REDEFINITION is your only option.
    Without knowing what you are trying to accomplish only general advice can be given. You even mentioned that you might want to use a different set of columns than the curren table has.
    A standard heap table uses ONE segment for its data (ignoring possible LOB segments). A partitioned/subpartitioned table uses ONE segment for each partition/subpartition. This means that ALL data must be moved to partition the table (unless you are only creating one partition).
    This means that every partitioning scheme that uses a different partition key requires ALL data to be moved again for that test.
    Provide some information about what problem you are trying to solve.
    >
    Is this quicker than datapump?
    >
    Yes - exporting the data simplying moves it all an additional time. Ok to export if you need a backup before you start.
    >
    Found artcle which talks about using merge option on datapump import to convert partitioned table to non-partitioned table.
    >
    How would that apply to you? That isn't what you said you wanted to do.
