How to bind the data source to a custom class?

Hi all.

I use the chart control to draw two types of plots. One is a path of spectrum which refreshes all samples in a short time, and the other is a curve of time series which add than one sample of each time.  A chartcollection was related to the data source, however, and draw the spectrum seems to not cool off very quickly. Was it due to the propertychanged event? In order to improve the speed of response, what should I do to deal with the data source?

I went through your response and the help files and found I made a stupid mistake - I always used to Append method (double, double) and did not notice its format void Append (list, list).

Thanks for your patient response, Paul :-)

  • How to create the data source?

    I use MapViewer V11.1.1.7 B130111 delivered with BIEE.

    On the management data source page, there are 4 buttons like refresh, edit, delete, and purge the cached metadata. No create"" button.

    So, how can I create a new data source? I saw map_data_source article in mapViewerConfig.xml. Can I change the file for this?

    Yes.

    And preferably use a data source of the container. Which is set in weblogic and add data source information in mapviewerconfig.xml as a containerDS

    for example

        
                 container_ds = "jdbc/mapperDS.
                 number_of_mappers = "20".
                 max_connections = "100".

  • what I do wrong to the data source?

    Sorry, I looked around to try to find the answer to this, and I could not.

    I have two web applications. One, 'Locations', has a list of addresses for several stores, with tags such as {location_street_address}, {location_phone_number}. Another web application, "StoreGallery", holds elements of demonstration to these stores, and in it I set places as a data source field. So that for each article, they can associate an element with a specific store.

    In the details of StoreGallery template so I added one of the places tags, thinking by after you set the data source, the tags one could work in the other, but they do not. I was able to find tutorials on how to create the data source field, but not on how to actually apply them in models.

    Hi Kenneth,

    The current version of the web apps does not work like that.
    When you define a data store that makes just provide a link to the other element of web app that you associate. You can't put tags that you built from a web app in another.

    The release of data source which is a hypertext link is the only thing you have.

  • search form Web apps: how to retrieve the value of the data-source type field

    Hello

    My question is:

    How can I retrieve the value of the source field of a web - app data-types when you insert the "form web search apps" on a web page.

    I have a web application that contains fields from the data source of the type. These fields to recover the (data) value of the 'web app' - 'elements of the field' field of another web application.

    When I insert the form

    Web apps

    Web apps-search form

    It displays the fields with the field (ie. string, number) types other than type of field 'data source '.

    (Note: in the mode 'model of list' module of data tags, the fields of the data source are visible).

    What other (alternative) possibilities are there to create a search form?

    Thanks for your help.

    Kind regards

    Carla

    By chance, I came up with this workaround. Of course there are other methods to get your data from a web - app, but if you want to use the 'Web apps search form', it would be a workaround.

    I noticed that the "Web apps entry form" contains all the fields of web applications for your web application (including the fields of the data source).

    It is possible to add the fields to the form of the "Web apps entry form" in the «Web apps search form»

    If you insert the "Web apps entry form" on a blank page, you will see all the fields in your web App including the "data source fields. The names of form fields contain something like.

  • How to bind the user interface component to a display object that is created from a SQL query

    I use JDeveloper 11.1.1.2.

    I created a method in my ApplicationModule to create a dynamic ViewObject instance based on a 'voCode"passed in:

    public loadVO (String voCode) {} ViewObject

    ViewObject viewObject = findViewObject (voCode);
    If (viewObject == null) {}
    viewObject = createViewObject (programCode);
    }
    return viewObject.
    }

    I created a Client interface for this method and updated the control data of the ApplicationModule.

    The "Oracle JDeveloper 11g Handbook", I should be able to create a link from the tree and an executable methodIterator to the method of "loadVO" through the control of AOS data.

    I tried to manually add the binding to the definition of the page my page jspx, I like to see if I can replace an existing binding with this new binding.
    I was not able to add the link under "tree to create binding" 'Root Data Source' both 'Tree level rules' must be specified.
    I was able to specify the root 'Data Source' to point to the "loadVO" and the corresponding parameter, but not able to add a rule.
    When I clicked on the icon "+" to add the rule, anything that allowed me to clarify the rule (if I know which rule I should add).

    How can I bind the module of the application 'loadVO' method while it is exposed in the data control to provide data to a UI like PivotTable component?

    On the other hand, I was able to create the "methodIterator" first for the method 'loadVO' AM but I wasn't able to create a tree link to refer to the "methodIterator".
    Is it possible to call the method loadVO with the value of specific setting via the "methodIterator" of a bean method?

  • How to define JDBC Data Sources in Oracle MapViewer for Oracle database 12 c Release 1 (12.1.0.1)

    How to define JDBC Data Sources in Oracle MapViewer for Oracle database Release 1 (12.1.0.1) 12 c?

    Here is my setup in the conf\mapViewerConfig.xml:


    < name map_data_source = "mvdemo12".

    jdbc_host = "127.0.0.1".

    jdbc_sid = "orcl12c1".

    jdbc_port = '1522 '.

    jdbc_user = "mvdemo".

    jdbc_password = "7OVl2rJ + hOYxG5T3vKJQb + hW4NPgy9EN.

    jdbc_mode = 'thin '.

    number_of_mappers = '3 '.

    allow_jdbc_theme_based_foi = 'true '.

    Editable = "true" / >

    <!--  ****  -->

    But it does not work.

    After use "sqlplus mvdemo / [email protected]:1522 / pdborcl", it connected to the Oracle 12 c database.

    Anyone know it?

    Thank you

    11.1.1.7.1 use the jdbc_sid syntax, i.e.

    as described in the README file, mypdb1.foo.com

    -Sources of native data (no container) MapViewer can now use the service name of database instead of SID. To provide a db service name, you will use the same attribute of jdbc_sid, but specify the name of the service with double slashes in front, as follows:

    jdbc_host = "foo.com"

    jdbc_sid="//mypdb1.foo.com".

    jdbc_port = '1522 '.

    ... ...

    />

    Use a container_ds to the 11.1.1.7.0.

    that is, instead of using

    jdbc_host = "mydbinstance".

    jdbc_sid = "pdborcl12c".

    jdbc_port = '1522 '.

    jdbc_user = "mytestuser".

    jdbc_password = "m2E7T48U3LfRjKwR0YFETQcjNb4gCMLG8/X0KWjO00Q ="

    jdbc_mode = 'thin '.

    number_of_mappers = "6".

    allow_jdbc_theme_based_foi = "false".

    Editable = "false".

    />

    use

    container_ds = "jdbc/db12c.

    number_of_mappers = "6".

    allow_jdbc_theme_based_foi = "false".

    Editable = "false".

    />

    In my case the Glassfish 3.1.2.2 JDBC connection pool definition has been

    Property

    URL jdbc:oracle:thin:@mydbinstance:1522/pdborcl12c.rest_of.service.name

    Uncheck the wrap JDBC objects in advanced Panel, that is, the page properties change JDBC connection advanced pool.

    Add a resource to that newly created JDBC pool

  • Specify the data source by default PIF

    How do you determine the Data Source by default "default"?

    Let's say I have three sources of JDBC, named BIEE_TRAIN, Oracle BIEEand demodata. They are displayed on the login screen of NEED in that order. I also have a file named data source, demo files.

    When we create a new set of data, there is an option button that indicates the default data Source. Looking at the page of the report, we see that the default data Source is set to BIEE_TRAIN. Why BIEE_TRAIN was selected? Selected by default because the data source is ranked first in the JDBC connections? I do not see a box to check, or any other way to report a particular data source as the value by default "default".

    In C:\OracleBI\xmlp\XMLP\Admin\DataSource\datasources.xml, the four sources are listed in the following order:
    demo
    demonstration files
    Oracle biee
    biee_train

    How can I change the default system? How would have defined the demonstration files, for example, as 'default' my system default data Source?

    It automatically sorts by NAME.

    And the default is Firestone I guess.

    If you want to default, call it as letter starting with "A".

    BTW, you can even restrict the data source based on the user, under Security admin role.
