  • Create Cubes Error

    Hi folks,

    an error keeps buggin me and I don't know what it is. I have the following 4 dimensions created and elements added to them using the PHP functions:


    So far everything works fine. But when I try to create a cube using these dimensions I get an error (-50 by the PALO server, whatever that means???),
    I get the error either way: using the Excel Modeller or using the palo_database_add_cube() function. In the modeler it doesn't say an error encountered, it just won't create the cube. The weird thing is, it works when I only use the dimensions "Host" and "Datum", any combination with other dimensions leads to the error. So I figured there is something wrong with the dimensions "Kennzahl" respectively "Website", but I can't find out what! Following are the .xml files of the elements

    <?xml version="1.0" encoding="utf-8"?>

    <Dimension TimeStamp="1140444447.0">Kennzahl
    <Element Type="S">Klicks</Element>
    <Element Type="C">Alle Kennzahlen
    <Consolidate Factor="1.000000">Klicks</Consolidate>


    and for website it is:

    <?xml version="1.0" encoding="utf-8"?>

    <Dimension TimeStamp="1140444449.0">Webseite
    <Element Type="C">Alle Webseiten
    <Consolidate Factor="1.000000"></Consolidate>
    <Consolidate Factor="1.000000"></Consolidate>
    <Consolidate Factor="1.000000"></Consolidate>
    <Consolidate Factor="1.000000">qscshop</Consolidate>
    <Element Type="S"></Element>
    <Element Type="S"></Element>
    <Element Type="S"></Element>
    <Element Type="S">qscshop</Element>

    This is my php code for adding the cube

    $cube_data = array('Host', 'Datum', 'Webseite');
    $add = palo_database_add_cube($connection, $database, 'Test', $cube_data);

    The $connection is valid, and the $database variable has a valid value.

    can anybody help me with that? It would be great if there was a lookup
    for the server error codes. I get a lot of them and never know what exactly they mean.

    Thanks in advance!

    it seems that there is a gap in the structure definition:
    String Elements can not be consolidated (how should this be possible)
    Therefore in Palo side it is necessary to define how String Elements are to be handled:
    they must either be exculded from consolidation in the way that:
    - Palo ignores them when they are added to a consolidation path or
    - Palo does not allow adding them to a consolidation path

    Other MOLAP Tools only allow them to be
    - not in a consolidation path
    - only in one dimension per cube
    - and this one dimension has to be the last one in the order of the dimensions within the cube.

    I don't know whether Palo needs these restrictions or not but a definition is to be made.

    Good day, Glasnost

  • I don't think the string dimension currently needs to be the last dimension, at least not from my test earlier creating some sample dimensions and placing them in a cube with the Eclipse RCP. I was allowed to create and write data to a cube containing 3 dimensions, in which I deliberately set the second dimension to contain string data.
    I don't think that it's really an issue, but the string shouldn't a be able to be consolidated, and in anycase it wouldn't make sense.
