How to specify a custom design rule?

I want to have a design rule to find the names of table > 27. The supplied rule is with a length of 30. Seems like it should be pretty easy to do if I could copy the current rule and modify, but I can't seem to find a way to even see the code for the current rule.

Thank you.

Hello Kent,

These rules are build-in before support for custom rules has been added, and you do not see the code. There is a custom rule example provided with the tool and I posted some rules associated with the physical model here in the forum.
Here are two examples:
(1) without the function definition

if(table.getName().length()>27){
 false;
}else{
 true;
}

you see there is no return statement, the last expression is taken as the return value, and this might be confusing
(2) with a function definition

/define
function checkName(table){
 if(table.getName().length()>27){
  return false;
 }else{
  return true;
 }
}
//invoke it
checkName(table);

The rule should be created for the Table object and motor set to "Mozilla Rhino.

  • Error in custom design rules: importClass is undefined

    Hello world

    I have a problem with the rules of custom design of data model 4.1 (Beta).

    in the 4.0.3 version I have some rules to design personalized with the option: importClass (javax.swing.JOptionPane);

    for the error exception and MessageBox databases.

    -in the 4.0.3 version this option works very well

    -in version 4.1, this option generates an error

    If this option is changed in Version 4.1? or where is the error?

    Thanks for any idea, suggestion...

    Martin

    I found the solution!

    in the 4.0.3 version the Data Modeler used Mozilla Rhino as engine and version 4.1 Oracle Nashorn.

    If you need to load the 4.1 version compatibility script to use the feature of ImportClass.

    Example:

    Load compatibility script

    Load("Nashorn:mozilla_compat.js");

    Import Java class der

    importClass (javax.swing.JOptionPane);

  • How to specify SQL custom querying the db with option to delete logical adapter

    Hi all

    I write a composite SOA application using JDeveloper SOA Suite 11.1.1.4 connection to a SQL Server database with the help of a Secretary of the poll the DB adapter with the logical delete option to send data to a BPEL process.

    I have requirements that go beyond what is supported in the UI JDeveloper for polling of the adaptor DB options, namely:
    * update several columns to mark each line read, and
    * specify different SQL to remove operation logic based on if bpel surveyed data processing was successful or not.
    A complicating factor is that the query contains two tables. Here is my complete use case:

    (1) mark will select data from two tables: for example 'headers' and 'details' simplified for this example:
    Table: headers
    HID - primary key
    name - plate
    status - "raw", "transformed" or "error".
    processedDate - null when the data is loaded, the DateTime current when the treatment of the line
    Table: Details
    HID - foreign key pointing header.hid
    attr - name attribute of data
    value - value of the attribute data

    2) there are a many relationship: 1 from detail lines to the header through the hidden columns. The adapter db SELECT the voting clerk must return results of an outer join consisting of line a header and the associated detail rows where header.status = 'no' and header.hid = details.hid. (This is supported by the UI Jdeveloper)

    (3) the survey data will be sent to be processed by a bpel process:
    (3.1) if the bpel treatment is successful, the logical delete operation (UPDATE) must set header.status = 'transformed' and header.processedDate = 'getdate() '.
    (3.2) if bpel treatment fails (for example hits a data error during the processing of the selected data) the logical delete operation (UPDATE) must be set to 'impossible' = header.status, header.processedDate = 'getdate()' and header.errorMsg = '{of the text returned by bpel}.

    Several parts of the #3 are not supported by the UI JDeveloper: update several columns to mark the addressed line, using getdate() to fill a value of one of these updates to the column, update of different operations based on the results of the BPEL, processing of the data (success or error) and using data from BPEL treating it as a value of these updates of column (error message).

    I found examples that describe the specification that is customized by using querying SQL Delete option to create a template and then modify the toplink files to specify custom select and update SQL to implement a logical deletion. (for example, http://dlimiter.wordpress.com/2009/11/05/advanced-logic-in-oracle-bpel-polling-database-adapter/ and http://myexperienceswithsoa.blogspot.com/2010/06/db-adapter-polling-tricks.html). But none of them match what I have in my project, in the first case because maybe because I use a newer version of JDeveloper and the second I think because in my case, two tables are involved.

    Any suggestion would be appreciated. Thank you, John

    Hi John,.

    You raised a good script.
    First of all, let me say that the purpose of the DB of the election operation, is to have an option to start the process of a DB table/view and not update several fields in a table (or have other complex manipulations on the table).
    Thus, when choose update a field in a record, after reading it, you "say" the engine not to question this record again. Of course, I guess you can find a solution/workaround for it, but I don't think that this is the way...

    The question now is what to do?
    You can have another DB adapter where you can update the data after you have completed the process. In this case, after reading the data (on the query operation) - updated the "transformed" for example = header.status and after processing the selected data update the rest fields.

    Hope it make sense for you.

  • How to apply a custom rule just for a relational model?

    Hello

    My drawing has several relationship models, but I want to check custom rules or apply custom transformations just to a specific relational model.

    So, I created a 'personal library' called 'Custom design rules' with the following function:

    function checkColComments() {}

    result = true;

    ruleMessage ="";

    If (! column.getCommentInRDBMS ()) {}

    ruleMessage = 'no comment in RDBMS defined ";

    errType = "error";

    result = false;

    }

    return the result;

    }

    In the 'custom design rules", I created a rule"Comments column Check", referring to the library and the method created previously.

    But, even if I chose the "relational model" which I intend to apply this validation rule, run the script for all open models.

    This seems a bug (I use v3.3.0.747 DDM,) because it is asked to select the template to apply the script, but subsequently, this selection is ignored.

    I have not yet tried the v4.0EA to see if it has been resolved or not and the release notes does not refer to the list of the bugs fixed (or I have not found) as it was in version 3.3.0.747.

    No idea if I'm doing something wrong or if the bug still exists?

    Thank you!

    Hello

    design (including custom) rules are still applied on a relational model. I wasn't able to reproduce a case when this rule is broken.

    However, there is a bug in the 'Custom Design Rules' functionality and the rule is applied on what is called "current" model and model selected is ignored.

    Which works very well in the "Design rules" feature, where the selected model is used.

    As workaround for 'Custom Design Rules' - you can generate DDL by using "Generate the DDL" icon and this model will become as "current"relational model. "

  • How to convert a set of rules to update a rule update shared?

    I created a set of update rules in the Tools section of the E10 data, but it does not appear in the list of rules to update shared and so I am unable to use it in the stages of treatment for my forms (even if I can still use it in programs).  Anyone know how I can convert my update rule set in the Tools section of data in a rule to update shared without having to recreate?

    Thank you very much.

    Just to clarify this was always so even when she was just E9. Rules update form could never be used in the program generator and updated program rules Builder could never be used in forms. Several times I was caught swearing on my screen because of this, especially when I was brand new to Eloqua and has just completed the construction of a massive update rule in the WRONG section.

    Here is some information on why they were different and are always different.

    In a program, you have a contact into step - the update will unfold on the contact which is the step at a time. If you look at a program generator update rule it doesn't let you not specify criteria for 'research', example of email address because he knows that it will be applied to, the person in the step at the present time.

    A form update rule has a criterion of "research", usually the email address. A person submits a form, they give you their email address, the update rule needs to know what field should we use to make a match in the entire database to find out who it should be updated. You can also not use same email address, you can use other unique identifiers or a combination of different areas.

    In my view, there are a few other differences with the two types of update rules, I think you can make some types of joint and date stamping in one where the other you can't, I don't remember the exact details but I think that there are a few minor differences.

    In this context, it does not mean always, they must be different, it would be amazing if you could use the same update rule in the program as well as the forms generator or at least copy a rule to update the forms in the format program generator, as a kind of conversion, where a person made a mistake not that it never happens.

  • How to add a custom WD screen button to call a workflow in siebel?

    Hi all

    We have an obligation to have a custom button to (after the execution of the rule) summary screen 'Create opportunity', by clicking on it a new opportunity record must be created in Siebel. As we know the link 'Save' calls 'PolicyAutomationSaveSession' incoming to the web service method and saves the session table information and we can change the workflow presessional and post-Forum. But we do not know how he calls the service method and where is the defined mapping.

    Can you please help me on how to add a custom button and how to call a workflow next to siebel to implement this requirement?

    Also is there anything that can help me to add a custom in the display button and add the code behind the button?

    Thanks in advance!

    Kind regards
    ALIOU

    ALIOU,

    There is no easy way to map an arbitrary Siebel Workflow to a button of the OPA. It can be done through a custom action, and with the addition of the code. Here's how it was done for the recording function of the Web analytics that you see in the OPA for Siebel connector.

    1. strip the workflow as a Siebel "Incoming Web Service"
    2. write the code to call the web service
    3. implement an event listener which will execute the code at the right time

    Documentation on the event for the determinations of Web listeners can be found in the "10.3.0 Oracle policy Automation Developer Runtime help" in the section "Events and event handlers" "

    I see that you have copied the text from the library and put it as a script. Script and the library are used/evaluated in a different manner - function a return statement, last phrase is taken as for the script return value.
    In your case - you just call the function defined (you definition, no use):
    checkcomments (table);

  • SQL datamodeler: design rules

    Hello
    In datamodeler of sql, you can check your design against a number of design rules.
    Is there a way you can influence these rules of design?

    -can you tell whether or not a design rule applies?
    -You can change gravity?
    -You can change the rule (for example other rules of the naming convention)

    Best regards Erik

    Not at this stage. We want to allow users to change them in the future. There are ways you can influence some of them. So now the dialog box properties of the model there are naming options. If you change these, you can influence the design rules. Also, in the Options General, there is a section of naming standards. So that you can put naming standards here and these are used in conjunction with rules Designer.

    I'm working on a paper on the naming standards and design rules and how they are used. It is not yet available, but I'll put it on the page of modeling data when it is ready.
