How Active Data Model Works?

Some one can explain to me, how Active Data Model Works?
All data is managed in memory? When de changes go to the database? benefits of use.
Thanks in advance.

ADF BC: Active data model question

Hello,
can somebody confirm that row iterator of detail view object obtained from master view using view link is different from row iterator used by active data model (getDetails() in application module) ?
My problem is:
I have a detail view object with multiple updateable entities. When I create a new row like this:
   Row row = masterViewRow.getDetails().createRow();
   masterViewRow.getDetails().insertRow(row);I don't see this row on web page probably because multi upd entities view object doesn't notify other iterators about changes by default.
I have to use
   Row row = appModule.getDetails().createRow();
   appModule.getDetails().createRow(row);to make it work
Can I omit use of application module and use master view object only to work with details in model and have changes visible in layout?

Nobody can answer this.
Where are all the ADF experts.
Please help solve this issue.

Active data model problem

Hi all!
I have a problem working with ADF BC, i think it's caused by the Active Data Model.
I have a jspx with an adf:table based on a a ViewObject ( with an underlaying EntityObject ) that queries for all employees that matches: attributeName = '0' .
Then I navigate to another jspx where I can create employees. So I create a new employee with a value on that attribute different from '0', for example '1'.
Finally I navigate to the first page and... THE NEW EMPLOYEE APPEARS IN THE ADF:TABLE!!! Aulthogh his attribute value is not 0!!!
Any suggestions? Is it a problem related to de active data model?
Thanks in advance!

Hi,
the filter is applied to the query, so you will have to re-execute the query to not see the new enetered value. The query filter is not applied to new records added to the current collection.
So add the user, commit it and re-query the VO

Can SQL Developer Data Modeler work with OBIEE?

Can SQL Developer Data Modeler work with OBIEE? Can we export the data model from the Data Modeler and import it into OBIEE? Or export the OBIEE metadata to the Data Modeler for Data Model defining?

How do data packages work?

how do data packages work specifically?
or how does the 25mb data package work?
any specifications?

In addition to the information SuzyQ has provided, here is a link for additional information http://support.vzw.com/clc/faqs/Calling%20Plans/nationwide.html

Report parameter textboxes and execute button is missing. Date Model works.

Hello,
I created a BI Publisher Data Model. Did the testing of it by generating XML sample data.
The data model requires 3 parameters as input. All worked fine for generating the XML.
When I now create a report with a .rtf template that uses the data model. then
no parameter-entry header appears. no execute button either. why is that?
thanks.

I think the issue is a bigger one. when I try to upload the template I get the pop up saying "Object reference not set to an instance of an object". The .rtf template is not bigger than 2mb.

How does movies model work?

I've been a Mac user since 1987 and always loved Apple for its intuitive UI. However, the model Apple's using for viewing purchased movies on iDevices is absolutely confounding me.
At one time, purchased movies seem to need to be downloaded, and you could only store as many movies as your iDevice could hold. This wasn't ideal, especially since the system tended to default to selling/offering the HD versus the space-saving SD format. I have over 40 movies but I can't afford a 64GB model, so I did a lot of swapping of movies.
Then (perhaps with iOS 7?) suddenly it seemed as though you could stream all of your purchased movies from the cloud; no more wasted iDevice space, unless you wanted to store a couple for those out-of-wifi situations. Great!
However, now I can't figure out whether my movies need to be downloaded or not. I got a new iPad and the movies didn't appear after I'd selected them in iTunes on my computer with the iPad attached and syncing. I tried going to the iTunes Store > Purchased and there's this weird Not in My Library grouping of movies. I've purchased these movies; how can they not be in my library?
DO I need to download every movie to my computer before I can stream it to my iPad? Do I need to partially download movies to my iPad before I can stream them? Or is this streaming thing just a hallucination and they need to be downloaded to each iDevice?
Help!

In order to get an answer that is specific to the question, it often helps to ask a question that is specific enough to answer!
It might therefore help if you explain what is it you are trying to do, or wanting to do? Otherwise, all we can likely do is tell you that to use the radio feature in iTunes, you select in on the left, then pick the genre of radio station you want to listen to from the list, then from there, select the actual station. You do, of course, need an internet connection because it streams data from the station.

How the data storage works?

i'm looking for new ideas about how to save an stl has map into the disk..

You could use a Berkeley DB database to store the data from an STL hash_map.
Berkeley DB btree and hash databases store key/data pairs. These can contain variable length key and/or data items.
It should be fairly straight forward to iterate through a hash_map and store each item in a database.
The best places to start learning how to use Berkeley DB are the Getting Started Guide:
http://www.oracle.com/technology/documentation/berkeley-db/db/gsg/CXX/index.html
Or the examples distributed with the source code.
Please let us know if you have more specific questions.

How does data backup work?

I just got an iPhone 5, and I don't want to lose all my game progresses on my old 3gs when I recover all my apps on the new phone. Will iCloud's data recovery/backup do this for me? (eg. All my cut the rope level progress...etc) I haven't activated the iPhone 5 yet so will that help?

iPhone 3GS:
- Backup using iTunes/iCloud
- Update your iPhone 3GS to 6.0.1
- Restore from backup using iTunes/iCloud
iPhone 5:

How to auto scroll a table to last row when using Active Data Service? 11g

Hi all,
Has anyone got any experience with the ADF Active Data Service?
I am using an af:table in combination with the ADF Active Data Service and I want the table to scroll to the latest row when new data arrives.
It is basically a simple setup:
The value attribute of my table points to a bean that extends CollectionModel and implements ActiveDataModel. This works perfectly. A soon as I receive new data in my bean, the table is automatically updated (e.g. a new row is inserted). I use JDev version: 11.1.1.3
The problem is that I can not get the scroll bar to move down to the last row automatically when new data arrives. The auto scroll only works for the client that actually performs a submit. In other words the person that submits the new data, will see his scrollbar move down, this is because I added the following code:
RowKeySet rowkeysset = chatTableBinding.getSelectedRowKeys();
rowkeysset.clear();
rowkeysset.add(getRowKey());
AdfFacesContext.getCurrentInstance().addPartialTarget(this.chatTableBinding);
This does not work for the clients that receive the new data via the Active data model. Apparently the active data service partially refreshes the table, but not in such a way that it sets the selected row to the last row?
My table definition:
<af:table value="#{pageFlowScope.chatBean.instantMessagingChatwindowBean}" var="row"
id="t1" columnStretching="last" rows="10"
styleClass="AFStretchWidth" autoHeightRows="10" contentDelivery="immediate"
horizontalGridVisible="false"
verticalGridVisible="false"
disableColumnReordering="true" displayRow="last"
rowSelection="single"
binding="#{pageFlowScope.chatBean.instantMessagingChatwindowBean.chatTableBinding}"
inlineStyle="height:80px;">
p.s.
The table is used to show incoming chat message.
I am building a chat client (taskflow) in a Webcenter application. The concept is similar of that presented by Lucas Jellemain in his blogpost on building a Google Talk Client http://www.oracle.com/technetwork/articles/jellema-googletalk-094343.html

Dan,
This is a thanks for posting your findings. You saved me quite some time.
<af:selectBooleanCheckbox id="showOnlyActiveSubscriptions" selected="true"
label="Show only active services:"
value="#{servicePortfolioBean.showOnlyActiveSubscriptions}"
autoSubmit="true" />
<af:table binding="#{servicePortfolioBean.serviceTable}" ...
partialTriggers="showOnlyActiveSubscriptions">
Of course, when I add a "ValueChangeListener" to the selectBooleanCheckbox, the PPR stops working. :( I wonder why?

How to Import data models into BPA

How can data models be imported into BPA? We understand that models can be imported from other
BPA repositories. We need to import from something that does not start out as a BPA model. We know how to import the data objects using the Process Generator. But do not understand how to efficiently import Cluster or entity objects (representing tables) connected to ERM Attrribute objects (representing fields). Currently only an EPC model can be imported using the process generator. We've tried importing structures using UML import of class models, but the resulting model is not usable in standard data models.
Any ideas?

Have a look on this thread:

Oracle BI Publisher no columns loaded from data model

Hello Guys,
I use Oracle BI Publisher 11g. Have created a data model by using
the JDBC thin connection to a 11g database. The creation of the data model
worked fine using a SQL query. Now in the report creation wizard, I select
the "guide me" option to see how nice the wizard is.
The problem comes here, on the second window I should select the columns
but I only read "no columns available". Why is that?

Hi Metalray
For BIP report sample XML data is importent. with sample data you cannot generate the BIP reports.
Follow the below steps, you can achieve your expected BIP output
After crating data set in the data medel save the data model then click on
--get XML output option on right side of the top-corner.
-- then selet no. for the nuber of rows to return dropdown option,
--then click on Run. Then save the sample data by clicking on Save as sample data option.
--then it will take you to the data model page, now again save the data model
--and use it for creating the reports.
Now you were able to see the available columns in the the second window of guide me option
please mark if it helps you..

SQL Developer Data Modeler - integration with subversion

I just discovered the release of SQL Developer Data modeler, and found this to be very interesting.
We are still using Oracle Designer for database design, but we are looking for a replacement (for several reasons).
My question is quite simple:
Given that the modeler uses a filebased repository, and also given that we have several developers potentially working on a data-model at the same time, how does Data Modeler integrate with subversion for source control etc.?
Can the repository itself be under source control, and checked in/out directly from Data Modeler?
Or will only the output files be candidates for version/source control?
Let me admit right away that I have not read much of the data modeler docs, and I have also not downloaded/installed it (yet), but does anyone have pointers to docs on this , or general input/knowledge around it.
On a side note, I must say that it puzzles me that a company like Oracle, that delivers one of the best databases doesn't use its database engine to host the repository, but instead chooses to go for files (I assume xml) "scattered all over the place"....
Well, I guess they a have a reason for it..
Anyway:
Sql Developer Data Modeler and Subversion anyone?
Jens

Hi Jens,
It's early days and the initial implementation is indeed file based. Though I'd say not xml files "all over the place", but in ordered folders. Yes, as a database company it does make sense that we'd have a repository for managing and versioning metadata. However the tool supports Oracle and other databases and many companies use open source version control tools, such as Subversion and so anyone using the Data Modeler today can use it with Subversion regardless of the database they are designing for.
We do plan to have a repository, but in the 6+ months of the early adopter program found that many of the early adopters were happy to place the files under source code control using Subversion and in so doing also managed the multi-user development.
Integrated Subversion support is planned for a future release.

Data Modeler Logical Data Type confusion!

I don't get it.
When defining a logical model, I want to assign data types to the attributes in my model.
I understand a logical datatype like money, and that a logical datatype might be implemented differently in different databases. The concept makes perfect sense to me.
I pick a datatype from the Logical Types.
It ignores the logical datatype that I picked and puts in another datatype instead. I'm guessing that it's a physical mapping. I would understand the logical-to-relational mapper doing that , but I don't understand it happening at this point in the model life cycle.
Let's say I pick Money. It puts Double into the logical datatype, not money.
If I pick Date or DateTime, it puts Date into the logical datatype, so what is the point of giving me two types to pick from?
Seems kind of wonky.

David,
We will publish soon a document on how the data types work.
If you go to tools, Types administration you will see that a logical type is mapped to a native type and a native type is mapped to a logical type.
The logical type MONEY is mapped to DOUBLE for Oracle.
Types and domain files can be customised.
One could argue that the logical name MONEY should show up and not the native name. Showing the native name has the benifit that you see what the logical type is mapped to. Both approaches could have their supporters, no?
Kind regards,
René De Vleeschauwer
