Information about adf data model's state management in JSF/ADF faces?
Dear All,
i am developing an application with JSF/ADF faces + using
adf data model (EJB, not adf bc)...
i want to know more about state management of adf data model..
1. under what condition, will the data in the binding context
(methodIterator, variableIterator, accessorIterator..etc) be maintained accross
http requests? say browse pageA.jspx, pageB.jspx, pageC.jspx..then do data
in the corresponding pages saved somewhere else until session timeout?
2. how do the binding context data be saved ?? http session?
i can't find detail information in the adf bc dev guide and the adf dev guide..
could anyone give me more information about this?? any better document??
i have asked these question several times...but seem nobody can give me a
full picture about the adf data model's state management....it is quite important
in order to develop good application using adf data model.
my company have brought oracle's support service...can i get these information
through metalink (open a SR) ?? or actually no such information available ??
btw, after playing with adf data model for a few weeks, i do find it is very
hard to learn it... no complete document, information is just by providing example...
adf data model do make:
1. simple logic, supported by adf, more simple in coding
2. simple logic, not supported by adf, more complex in coding
3. complex logic, much more complex in coding...brain damage..

Hi,
actually, these pages don't explain the state management about the adf data model's iterators?
i want to know the state management of the iterators...for some iterators..it's
state is maintained across requests...
please see my previous post: ADF JSF data binding: why state maintained between requests? that Frank Nimphius said:
"in this case its the iterator that survives the page navigation"...
in the adf dev guide..section 5.5.5..it says: "Upon each request, the iterator bindings are refreshed to rebind them to the
underlying RowSetIterator objects. By default, the rowset iterator state and the
data caches are maintained between requests."
in dev guide, it seems state is maintained for request for the same page, but not
accross different pages. but in fact, the rowset iterator do survive...
any detail document that write down the actual behavior of the iterators?
thank you.
lsp

Need information about notification with SAP Netweaver Identity Management
Dear Experts,
I need some informations about send e-mail from SAP NIM. We want to send an e-mail after creation of sap users etc.
Please note that today we have a Domino/Lotus server.
I undertsood that we can send e-mail through the Identy Center (IC) component. But I did not find how to set up this solution? I did not find architecture informations?
Could you please provide me the different configuration steps?
Should I install another component? Or I just have to configure my SMTP Server?
Also, have you got the best practices for this step?
Thanks a lot for your help
Regards
Hocine NAÏHello,
For notification, first you need to create a repository of generic type and provide the lotus notus host details in the repository constant.
Eg:
EMAIL_SERVER abc.def.com
EMAIL_ORIGINATOR orignator mail ID
Then create a task with the "To Generic" type Pass.
Select the name of the function below in the Next data entry of the Destination tab of the pass.
and provide the attribute and value as below:
MSKEYVALUE %MSKEYVALUE%
EMAIL_RECIPIENT recipients mail ID
EMAIL_SUBJECT Hello %DISPLAYANEM%
LOCATION %LOCATION%
Eg of a Function to sent mail is shown below:
function SendEmail(Par){
Recipient = Par.get("EMAIL_RECIPIENT");
Subject = Par.get("EMAIL_SUBJECT")
Location = Par.get("LOCATION");
Body = "This is a report from SAP NetWeaver Identity Center at %$ddm.date% %$ddm.time%<BR><BR>";
Body = Body + "Your location is <B>" + Location + "</B><BR>";
Body = Body + "<BR>";
Body = Body + "Best regards<BR>";
Body = Body + "MaXware AS<BR>";
UserFunc.uSendSMTPMessage("%$glb.EMAIL_ORIGINATOR%", Recipient,Subject,Body,"%$glb.EMAIL_SERVER%",1); -

What To Do About Chatty Data Models?
I'm working on a legacy app that has some DAOs that are "chatty". There are multiple methods, each with different SQL, that bring back primitive values (e.g., double, String, etc.) This DAO is written in such a way that assembling one DTO to return to the client takes 70 distinct calls, each with its own network roundtrip.
What's the best way to go about correcting this?
Combining those disparate SQL queries into one big JOIN is a daunting task, made complicated by some other features in the implementation.
Is a stored procedure a possible solution? We're using Oracle 8i as the data store.
%Then to use one stored proc you would need one of the
following...
- Stored proc that returns several result sets (which
I have never tried with Oracle)
- Or a combined result set that allows you to
seperate out the different collections from a single
row (probably with empty fields.)I was thinking the latter.
This sort of thing is one of the cases where MS SQL
Server is a lot easier than Oracle, you create some
temp tables, fill them and then just select them to
get the values. In one case I had to use a 'temp'
table for a complicated collection process in Oracle,
but for Oracle that means that a real table must
exist.Oracle is the platform here. I'm not at all knowledgable re:M$ SQL. Sounds like it could be a fine solution.
Obviously you could create several procs as well.There's some push back on that, too. Views are in vogue. But if I could write a single SELECT to create the VIEW I'd be able to rewrite the Java to bring all the database back in one go, too. It's not that easy.
Why does it need 70 calls? Something like getting
all of the telephone numbers they first get the list
(1 call) then get each tn with a seperate call rather
than using a single select in the first place? That
sort of thing is easily reduced and there is no need
for procs.Sometimes that's what they're doing. (JOINing on the middle tier.) There are other idioms in play, too.

Information about the data left on the 3G usb modem
I am looking for a command line and convenient util in this case. I have not personally seen this documented on the following page and its child pages:
https://wiki.archlinux.org/index.php/USB_3G_Modem
It would be nice to know how much MBs are still left that I can use in, for instance, a 1-2 GB package. The Windows software, shipped by the vendor, can provide this information, so I would hope for being this available on Linux as well.
I have tried to use this "iftop -i ppp0" command, but that did not work out fine either. Essentially "wvdial mynet" helped as described on the wikipage. Any help is appreciated.
Thank you a lot in advance!

Need information about Master data source Enhancement
Hi Frnds,
standard Datasource for GL account attributes needs to be enhanced .
0GL_account_attr is build on SKA1 table basically .
in my case this basic table is added with 2 new fields which are needs to added to standard datasource.
DS>BIW_SKA1( extract structure)>DB view-->built on SKA1 table.
kinldy provide your inputs how to enhance this DS.
Thanks
RavinderHi,
Go to RSA6, find your datasource. From the datasource, find the extract structure.
Go to SE11, give your extract structure, Click on Display,.
Click on Append structure. Give the structure name starts with ZA.. or if any structure exits, use that structure.
Add your fields to the structure and activate it.
Remember the enhanced fields should not be hidden. you can make this change of your datasource in RSA6.
To develop the code for this, you have to create a project in CMOD. If the project is already created with the assignment of enhancement RSAP0001, then go to SE37, give EXIT_SAPLRSAP_002 (For attributes), click on display.
Inside this, include ZX... is available. Click on this and develop your code.
After this, go to RSA3, give the datasource name and check the data for the enhanced fields.
Hope this helps,
Regards,
Rama Murthy. -

Using the Oracle ADF Data Visualization Components in a standard JSF enviro
Hi,
I have asked this question on the JDeveloper and ADF forum, haven't gotten a response yet:
Using the Data Visualization Components from ADF in a JBoss 7.1.1
.. but I would like to ask the question here as well if anyone have used the data visualization components from Oracle ADF Essentials .. the free version ... using the graph components in general, but I am looking at specifically using the gantt chart component in particular ... in a standard JSF environment ( e.g. Tomcat + Mojarra, or JBoss with the built-in Mojarra implementation ) ??
I know there are other JSF charting components out there ...like the ones from PrimeFaces, but the gantt chart from ADF looks more ... well .. professional.People are not prone to answer questions that are not really a problem. You want to know something about a free product, install it and see for yourself. In any case spreading your question around is not going to help you, the people who know about ADF are still going to be looking in the ADF forum. If you don't get an answer there, what chance do you think you have that you'll get one here where it is off-topic?
I'll close with a word of advice: you generally pay for quality. If you want professional looking charts, you'll probably have to look at commercial products. -
Hello,
I need some further information about the data modell of SBO. An ERD would be great, but as far as I know there is no such diagram available.
Searching in this forum gave me the information that that there are two useful files:
- SBOObjectsTables 6.5.chm
- DB_Help.chm
I don´t have access to the marketplace, that´s why it would be great if someone could mail one of these files to me to [email protected]
Thanks!Done

I am using SP Server 2010. The requirements of a project are to:-
Search an external database so that we can bring back rows from that database with say 5 fields.
Create a list in SP to hold about 25 site columns
Use the list in (2) to add rows sourced from (1) and fill in the site columns specified in (2)
Poll the (1) to check if new rows have been added and, if they have, add them to the list in (2)
Could anyone please advise upon the best way to model these requirements in SP given this MSDN
documentation?
Using BCS presumably?
Should we favour External Columns in (2) as opposed to lookups for example (see my
post here)?
We are basically trying to convert an Excel Workbook to SP. If we have the option (and we may not) is Excel Services the best way to do this?
What is List Pattern we should adopt?
Thanks,
MazHi,
For your first requirement, yes, you can use business connectivity service to bring rows from the external database field.
You can refer the detailed article below:
Using Business Connectivity Services in SharePoint 2010
For your second and third requirement, yes you need to create external data column to fill the external database field data to the list in the list. As external list has limitation as the source of look up column directly.
More information about external data column:
Create a SharePoint List with External Data Columns
If your requirement "convert excel workbook to SP", yes, you can use excel service to display workbook content in browser directly.
More information:
Excel Services in SharePoint Server 2010
For your fourth requirement, you can create a console application with Server Object Model to check the data in the external list in first requirement, if there is data in the list ,then you can add the data to external columns in requirement 2.
Programmatically set external column
For the list pattern, it will depend on your business logic and you data count,if your data is very large, then you can use the large list pattern.
Thanks

Creating a join in a data model
I'm still a fairly rookie java developer, so I hope someone can help me with this question. I'm working on learning the data modeling aspect in JDeveloper (TopLink or ADF Business Components). If the Creating Business Components from Tables wizard doesn't create a join between selected tables, how do I go about relating the selected tables? Our database is Oracle 10g, for a 3rd party application where we don't control the schema. Thanks for any help.
Yes, You can create a viewObject that is based on entities.
When you shuttle the base entities to the right in the wizard there is a check box at the bottom that let you specify if they are updatable or not. -
