Split WD Components from a DC

Hello,
I must to migrate some WD Java projects from 7.0 to 7.3; I can migrate all of them, except one.
This DC has 11 WD Components (some of them quite big size); there are no errors within and I should deploy it and test it. The problem becomes when I'm not able to build the DC from NWDS 7.30; the system gives me the following error:
     [timer] WebDynpro generator finished in 2 minutes 58.251 seconds

I tried a lot of times... my computer configuration:

What can I do? Is it a machine memory problem? Or is it a server memory problem?
Maybe I should split some WD Components into more DCs... right? How can I do it? Is there some tool for that purpose?
Thanks!!

try to build again.
if not work, delete unrelated dc and build again.

Deletion of filter components from Bex Report in BI 7.0 via back end.

Hi,
I want to delete 2 filter field components from the BI 7.0 report via back end. Im using the Tcode RSZDELETE and giving the variable element UID, Inforprovide name, query tech name. But when i excute it says empty selection.
Other than this is there any way to delete query components at back end???
Regards,
Nisha

Thanks for the reply!
This is to delete the variable created??
My requirement is query specific , the restriction on the IO , ie the variable to be removed via back end.. that means deletion from that report..
hope my statement is clear enough to give me some light .

Restrict Deletion of Components from Service Order

Hello All,
I noticed that I am able to delete the components from the Components tab of a Service Order even after I have completely issued the components.
Is there a possible way to prevent deletion of components that have already been issued..?
I think I can use the Business Transaction RMKL in the system status GMPS. But I guess this will prevent deletion of those components which have not been issued to the service order.
What would be the best way to prevent deletion of components that have already been issued...?
Thanks
Jensibo

Hello All,
I don't know if you all received the last reply I posted against this thread... coz I am not able to find it in the thread. I had asked for your comments on any repercussions that may occur because of this config.
Anyway, the thing is, I followed Narashiman's suggestion and although I did not use the exact config he pointed me to, I used the config in the following nodes:
1.) Production --> Shop Floor Control --> System Modifications --> Define System Message Attributes
2.) Production Planning & Process Industries --> Process Order --> System Modifications --> Define System Message Attributes
and added an entry: Application Area = CN, Message No. = 750-Component & item & was already withdrawn and Category = E.
Having done this, the system did display the "Component & item & was already withdrawn" message when I tried to delete a component that was issued to a service order, but it did not delete the component from the service order. I was able to save the service order with the issued component still in the components tab.
Narashiman,
to specifically respond to your latest reply, I did find the node you pointed me to. But the trouble was that it did not have an entry for CN750 in it. When I tried to add an entry, the system did not let me do so and displayed the error message "Please specify a legal value".
So I went around opening each system message control node and finally found the two that I mentioned earlier that did work for me.
Thanks

NO Links or Associations created with the "Business Components From Tables"

Hello,
I have a strange problem. I'm working on a Fusion Web Applicaiton. In the Model project, I try to create some Business Components from Tables with the help of the provided wizard.
I select one of my IDE Connections, and I choose two of my tables as Entity Objects (*PATIENTS* and COUNTRIES - more details about them bellow), and also as Updatable View Objects. For Read-Only View Objects I select some other tables, afterwards I choose to create a default Application Module, and I press Finish without creating a Business Diagram. Everything works perfectly except of the fact that the wizzard has created everything but the Links and the Associations between my tables.
To be more precise, COUNTRIES is a simple table, only two columns - ID and NAME, and PATIENTS has some columns like ID, NAME, ADDRESS, DATE_OF_ADMISSION, COUNTRY_ID, where COUNTRY_ID is a foreign key to the COUNTRIES table. Both columns, PATIENTS.COUNTRY_ID and COUNTRIES.ID are NUMBERs. I was expectig the wizard to create a Link and a Association for this foreign key constraint I have between this two tables.
On the other hand, following one of the tutorials I've found, *"Developing RIA Web Applications with Oracle ADF"*, I've noticed that when I was creating Business Components from Tables based on the HR schema, all the Links and Associations were created as they were expected. I've also tried to create the same Business Components from Tables in my own project, and all the Links and Associations were in place. Somehow, it's not working for my particular schema (the one that contains PATIENTS and COUNTRIES).
Is there something I do wrong? I've made sure that all the FK constraints are enabled, alive and kicking. From my point of view, the tables are working and behavig as they should, but I can't understand why that feature of automatically creating the Links and Associations works on the HR schema but not on mine.
Please help!
Bogdan.

Hello John,
Of course I can post the scripts.
The schema name is "TEST". But you should know that there are some extra columns in the PATIENTS table, I've not mentioned before. As you can tell from the scripts bellow, the PATIENTS table has the following columns: ID (number), NAME (varchar2), COUNTRY (number), GENDER (number), ADMISSIONDATE (date), DIAGNOSTIC (number), FIRSTNAME (varchar2), SALARY (number). There are actually 3 FK constraints, I've only mentioned one for the simplifying the example. The first FK constraint is towards COUNTRIES, the second one is towards GENDERS, and the final one is towards DIAGNOSTICS. All this 3 tables have only two columns (ID as number, and GENDER as varchar2). I will post the scripts for all.
Here is the output of the Export DDL to Clipboard from SQL Developer for the COUNTRIES table:

JDI : DTR / CBS - Moving components from one scenario to another.

Hi all,
I have a series of Development Components that fall under the scenario 2 description of the DTR / CBS scenarios.
I am trying to move our projects into a scenario 2+, and have created the CONS and DEV projects in our SLD. I moved the development components from the old scenario into the DEV workspace through a propagation list, but I don't see the Development Components appear in the CBS BuildSpace, even after refresh.
Is it possible to migrate existing DCs from scenario 2 to 2+ and 3? Or do I need to manually create each DC and add all the components in it?

Hi,
It is stated in help.sap.com that there is no migration scenario from 2 to 2+ or 3.
So, it seems you should do it manually.
Sorry for non constructive ansewer.

ADF Business Components from Tables - adding more tables

Hi.
I have already created a ADF Business Components from Tables and added tables from the Oracle database.
My question is:
Is it possible to add more tables to the same Business Components model?
Not as a new Component Table, but with the same tables so i can use the same relations and mappings?

Hi and thanks! Yes, I am talking about recreating a the same View Object that i already has created. In my first model i had the tables Name and Address. I want to add a new table called zipcode to the same View som i can choose colums from the zipcode-table in the same View as Name and Address.
I'm not shure what you mean by Data Model tab? Can you spesify?
Thanks!

Integrating ADF Business Components from heterogenous data sources

Hi all,
has anybody experience in integrating ADF Business Components from heterogenous data sources like ViewObjects from a DB2 database as LOV in a ViewObject from a Oracle 11g?
What is the best practice approach to integrate such different ADF Business Components in declarative and programmatic ways?
Thank you!

thank you for the answer! We already updated out BC according to http://www.oracle.com/technetwork/developer-tools/jdev/multidatabaseapp-085183.html
The DB2 ViewObjects are exported as ADF Libraries and imported in the BC of the project with Oracle DB ViewObjects. In the root AM I created instances from the imported DB2-ViewObjects as well as from the Oracle-ViewObjects, but when I start AM test environment it takes the preconfigured Data Source of the root AM. So I probably will pesneed to create two AMs for the different ViewObject types and for the two connection types. My question is what will be best practices to use data from the DB2-VO of AM_DB2 in the OracleDB-VOs as part of AM_Oracle? Should it be done only programmatically or can it be done also declaratively and any suggestions how to proceed?
Thank you!

Why not generating adf bc projects and components from offline database

I imported offline database objects from my production database that is big. I would like designing some business components without necessarily the database running and be connected.
Is it a reason why an adf bc project may necessarily connect to an on line database ?
Why it is not possible to generate adf bc components from off line database objects ?

The ADF BC design time has always required a database connection, to be able to test the validity of expert-mode SQL statement for one reason, but not the only one. We have not lifted that requirement in the 11g release.
I filed ER# 6056701 to track your request. Thanks.

Updating Swing components from a different class

I would like to use the JTextArea component in a JFrame to display fast updating text from my application. My application is very simple. When the app launches the GUI is created then my application engine would start processing and displaying text data into the GUI. After reading about Thread safety when using Swing components I concluded it would not be a good idea for my app engine class to update the JTextArea class directly using methods such as .append(String).
I would be grateful for any suggestions on how I should approach updating Swing components from different classes.
Many Thanks in advance Sean

Hi
Why don't you just implement a basic callback method?
To do this the right way you should probably define a simple Interface that has a public method like updateProcessText(String s). Your swing class then implements this interface, basically forcing it to provide the public method you defined (this is no different than implementing ActionListener, which forces you to define actionPerformed). Secondly modify your processing class, so that it take's a class that implements the interface you just created, as one of the arguments in it's constructor. Lastly assign the argument from your construnctor to a private var - this will enable your processing class to have a handle to your swing class and update it as it pleases.
This might sound very complex, but it's really simple once you've done it once.

QST: Business Components from AIA Enterprise Business Service

Hi,
I'm new in ADF context. Ordinary I work with Oracle SOA Suite and AIA. We have a use case for customer with system integration over AIA. Now we will build a ADF Web Application and I found the "Business Components from AIA EBS".
- Will this wizard work with AIA 3.0 aka 11g?
- How to use this wizard? I save WSDL of EBS to local directory, but can't continue the wizard.
- Is it more compliant to use "normal" was of ADF and invoke Requester ABCS?
Bye
Marcel

Hello Robert,
I know this thread is quite old but I'd like to know whether anything has changed since then regarding the AIA Composite Application Framework extension? I've installed the extension (v 2.4) from a local zip archive (as installing through the update center failed - said it was installed but there was no new options under the Business tier) in Jdeveloper 11.1.1.1.5, had to change extension's paths to modules but still a wizard doesn't want to go to the next step, no error popup, no error in logs, nothing. Does it mean it's still not ready? According to the below site my environment fulfill all the requirements:
http://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/131167.xml
What is the preferred approach for an UI integration then? A requester ABCS seems to be an overhead and misconception to me but maybe I'm wrong :)
Thanks,
Piotr

Business Components from Any Device

Articles and sample code show how to use Oracle XSQL Servlet to access BC4J components from XML documents. Query the database and manipulate data from any Web-enabled device.
http://otn.oracle.com/sample_code/products/jdev/htdocs/x2vo/x2vohome.html
Regards,
-rh

Hi,
There are many ways to achieve this.
If your requirement is just to read data from different database (and not to update it), then using a database link would be a better approach.
You could create a database link in the primary database (target database being the one you would like to query). Base your sql query for the vo using the db link.

Business components from multiple datasources

Hi All,
I want to create business components from multiple datasource. Please tell me if it is possible in ADF framework and Jdeveloper 11.1.1.4
I opened the Model.jpx and tried adding the two datasource but it is showing as a dropdown list from which I can choose only one.
My requirement is to have components from one datasource and read data from a second database to create a LOV
Please suggest how to go about it
Thanks

Creating Business Components from Teradata tables

I'm trying to use the "business components from tables" wizard using a connection to a Teradata database. The business components get created without attributes. I'm getting an error where JDeveloper thinks that the Teradata table doesn't have a primary key. But I explicitly created the primary in the table (not be confused with a primary index, which is a different object from a Primary Key in Teradata). Am I really not supposed to use ADF to deal with Teradata data stores? I was hoping ADF would be able to work with databases other than Oracle. Is there maybe something special that needs to be done for the business components wizard to be able to recognize the primary key in the Teradata table? If we need to create all Teradata business objects manually then ADF isn't a goo option for Teradata.

I'm connecting via JDBC Generic. I'm using Teradata's JDBC driver. From a connection perspective everything works fine. I have the Teradata connection both as an IDE resource as well as an Application resource. When I expand the application connection it shows all schemas. I then expand my personal schema where I created the table with which I'm testing. It shows my table, all the table's columns, and under constraints it shows the table's primary key. But when I try to create the business components is when it somehow doesn't seem to recognize the table's primary key.

Generate BC4J components from Designer

Oracle Designer 9.0.2.80.1 vers: 4.0.12
Oracle SCM RON: 9.0.2.80.1 vers: 4.0.12
Oracle Jdeveloper 9.0.4.0 (Build 1419)
I try to generate BC4J components from Designer definitions from SCM.
In Designer:
I make workarea (WA27) as rep_owner
and child application (AP27) below WA.
I create one table (TABLE1) and one (Java) module to that simple table (TABLE1).
I check in and out application table and module.
In JDeveloper:
I make connection to SCM Database as user rep_owner
Test succeed and I see below Connection1Functions tables , procedures .. of the repository.
I do not see among tables just created table (TABLE1).
I make workarea an project below that WA.
Then I right-click on new project and choose Business Tier/Designer Generation +
Designer BC4J and click OK
Designer BC4J Generator Wizard starts
Wiard continues and I choose to workarea: WA27 and next
In next phase wizard shows only workarea WA27 not application below that.
I designer too old or do I need changes to definitions of the repository.

Language of the module have to be Oracle Forms (not JAVA).
After change wizard will find that container (= application) AP27 and modude(s) below that. OK!!!!
Fine !
