New ADF Taskflow transaction acquires a new JDBC connection?

Hi,
I would like to know more about ADF Taskflow transaction in relation to JDBC Connection.
tf1 ----(contains)---- page1 and call to tf2
tf2 ----(contains)---- page2
page1 - search objects
page2 - edit objects
I have two pages part of two taskflows, first taskflow does not create any transaction but the page1 in tf1 shows a searh screen for objects. I want to use transaction behavior of ADF TF for tf2 which is called in tf1.
My tf2 contains a page for edit objects, if i set New transaction as TF transaction behavior for tf2.
Does it really acquire a new JDBC connection?
I really appreciate if someone can help me with this.
Thanks,
Sunil.

"Is there any way to achieve 1 user ---> 1 connection ?"
I don't claim to be an expert on answering this as there's still a lot of things I need to investigate, and other's in the forum may chime in with more informed answers, but my understanding is you need to:
a) Use a single root AM
b) Configure your BTFs to use "shared data control scope" and the same AM
c) All of your BTFs should use "Use existing transaction if possible"
Because of "c", the very first BTF called, will not have a transaction to borrow, so it will establish a new transaction and therefore a new connection.
An alternative is, and I'm on shaky grounds here so please check this for yourself, but you could set all your BTFs to "use no transaction", which implies I believe they switch back to the model used in JDev 10g, where it's purely your AMs that determine connections/transactions.
As for saying 250 connections sounds very high, that's really up to you. If you build an application that you need to support a user with multiple transactions, it's your requirement that causes this. IMHO Oracle has given you the flexibility to build your application anyway you want, so it's up to you to decide if you want multiple concurrent transactions per user or not.
Finally regards the behaviour observed in WLS, note that the AM pooling options can influence the behvaiour of connections, so it's hard to say what you're seeing is correct, it depends. A suggestion is to install Oracle's Fusion Middleware Control application and use that for monitoring statistics; the FMW Control has smarts built it to help you observe the AM pooling and connection pooling. Andrejus Baranovskis has a few blog posts describing how he used this to track the pooling options.

ADF Taskflow Transaction Management Pattern

We have a project that consumes public common taskflows from a shared library.
How should we define the transaction management of these public common taskflows?
Who is respondsible for the transaction management?
I am able to understand the various transaction handling mechanisms suppported by ADF taskflow from the following link in the Developer's guide:-
http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/taskflows_complex.htm#BABICCGC
But I would like to understand the right pattern for implementating the above.
Please provide your inputs/links on the same.
Thanks in advance,
Navaneeth

There is no "right" way to do it. If the task flows are standalone, independent transactions that operate independently of any master task flows, then you can have them manage their own transactions; if you want them to join any existing transaction, you would do that. Without an example and without understanding the purpose for which you are building the common taskflows, it's pretty impossible to say much of anything.

Two jdbc connections in one transaction

Hi 
 
 In a method of a container managed ejb session bean I have two jdbc connections. I've expected, that they will be in the same transaction, so results of any actions performed with first connection will be visible for the second connection, but it is not. 
 I've checked, that there are two sessions at the database, so it seams that there are simply separate transactions. Is it a problem with a ejb-jar.xml (will paste it later), datasource (driver - Oracle Thin non-XA; 1PC selected) or such behaviour can not be achieved in WLS ? 
 
 regards

Hi,
 are you using XA transactions? Two separate JDBC Connections treated
 within one transactional context will require two phase commit (via
 Emulation or an XA database driver) Please check the connections
 settings within your datasources.

Please help me in identifying the steps required to deploy the adf task flow.
Thanks

Hi Durga,
Thanks for sharing the post. I think I am facing the same issue which you were facing.
I have already done these steps but still not able to get my custom page on click of a link which I created in OIM self service page :
1. I have created the adflibHomepagePortletsUI.jar as an adf library using Jdeveloper and copied it to oracle.iam.ui.custom-dev-starter-pack.war --> WEB-INF/lib folder after unpacking it.
2. have updated the custom-catalog.xml file inside oracle/adf/rc/metadata folder with the below lines :
<folder name="Sample Folder" id="sampleFolder">
<contents>
<resource id="helloWorld" name="Hello World"
description="Hello World Taskflow Reference"
repository="application.classpath"
path="adflibHomepagePortletsUI.jar/ADF_TaskFlow/WEB-INF+oracle+iam+ui+sample+homepage+tfs+hello-world-tf.xml#hello-world-tf">
<attributes>
<attribute value="coreDefault" attributeId="attr.background" isKey="false"/>
</attributes>
</resource>
</contents>
</folder>
3. repacked the war file and copied it in OIM_HOME/server/apps directory
4. Restarted the OIM server.
5. entered the following lines in jazn-data.xml present in user_projects\domains\idmdomain\servers\oim_server1\tmp\_WL_user\oracle.iam.console.identity.self-service.ear_V2.0\6bddg\META-INF\jazn-data.xml

<name>/WEB-INF/oracle/iam/ui/sample/homepage/tfs/hello-world-tf.xml#hello-world-tf</name>
<actions>view</actions>
</permission>
5. Login to self service console.
6. Click on the custom link who's actionListener is pointing to bean which is launching the taskflow created in the above steps.
7. On Click of the link a new tab gets open with blank page.
Please help me in knowing the step which I am missing in order to solve this issue.
Many thanks once again.

How to add new line in transact move order line

Hi,
i am able to update locaotr in Transact move order.
But i want to add two locators for the same line.
I tried to insert one more record in data base, but getting error unique index error.
so how can we add new line in transact move order line .
please help to slove this isse.
Thanks In Advance
Venu.

Hi,
the fact that your question is posted in Order Management section, does the move order automatically generated by OM?
nevertheless, i don't think you should (or allowed, in this case) to add a new line in transact move order. Transact move order only queries (not create records) the move order lines eligible to allocate and transact.
So, I don't see why you need to add a new line in transact move order.
You can, however, add a new line in the allocation of the lines, where for instance, you need to have half of the line allocated to one locator, and the other half to another locator
Thanks

New Write up transaction type which can post to Affiliated company

Hi Gurus,
Can you please help me with this request.
I have been asked to create the New Write up transaction type which can post to Affiliated companies copy of transaction type 700.
But i dont see any such option (Posting type) in transaction AO78.
Where as i can see the option in Transaction AO73( Acquisition) and AO68 (Retirement).
Can you please guide me how can i create this transaction type if i can and the reason if i cant.
Appreciate your time and early reply
Regards

OA81 is a general transaction. and AO78 specific for that kind of transaction types.
I think these field are hidden in AO78 for the reason that you can't use Affiliated company.
I never have seen a screen with Write up that you can fill in an Affiliated company.
For me this have only sense for postings between company code's.
You can tray to change the values by using the debugger, but it can give nice other effectslike that it is no longer possible to run the depreciation run when you have used this transaction type. Or it is working now but never again after an upgrade. There is a reason that you can't use these fields.

Solman 7.0 - Question regarding "New Maintenance Optimizer Transaction"

Hi All,
Since I'm quite new on Solman transactions, while monitoring my queue, I found 4 tickets that says "New Maintenance Optimizer Transaction".
This is what's inside:
"Internal Note SOLMAN_ADMIN 08.04.2014 08:41:25
The status was set to the value 'Selection'"
Can someone help me on where to find information regarding this, or if this is something I should take a look at?
Thanks!

Hi Bua,
Somebody has created an new maintenance transaction from MOPZ of solman, which is used for generated XML for applying support packs and EHPs.
Selection mean, that the user was selecting the components but has now done anything or updated the status

Transaction in a new task closed unexpectedly

Hello,
My requirement is open a new task from my program and calling an specific Z transaction in the second dynpro. I have managed to do this by using a CALL FUNCTION 'my_function' IN UPDATE TASK. However, when the user continues working with the new transaction in a new task it closes unexpectedly because the transaction arrives to a CALL METHOD sentence.
Do you know how to solve this situation?
Thank you,
Óscar

Hi
It's not clear if you want to run another program in a new session or you want to open a new dialog where user can run the new transaction.
IN UPDATE TASK is the option to run a function module in a UPDATE process (it's triggered by COMMIT)
STARTING NEW TASK task is the option to open a new session

When will new ADF UIX demo be released?

Are there any one can tell me when the new ADF UIX demo based on uix 2.2 be released?
I want to know if we can get databind uix tree component (or other ui components) from ADF data action control which return dataobject and something else.
Thanks a lot.

Hi Daniel,
Are there any one can tell me when the new ADF UIX
demo based on uix 2.2 be released?I'm not sure when any sample applications will be released, but there is an ADF UIX tutorial available here:
http://otn.oracle.com/products/jdev/collateral/tutorials/9050/adfuix_tut.html
I want to know if we can get databind uix tree
component (or other ui components) from ADF data
action control which return dataobject and something
else.I'm not sure about the tree component - I'll try to find out whether that is/will be supported. Once your data controls are available in the Data Control Palette, you can bind them to components in your UIX page by:
1. Selecting the data control that you want to bind.
2. Selecting a component type from the "Drop As" choice.
3. Dragging the data control onto the UIX page.
This process is illustrated in the tutorial above.

What does this error message mean: "Please acquire a new SIM (H5006)"

I tried accessing my cellular data and got this screen:
"The SIM is currently active and not available for activation on this device"
"Please acquire a new SIM (H5006)"
Any ideas why this would happen?
Thanks,
Ron

After continuing to get the H5006 error today, went to the Apple store, and after 85 minutes of trying to fix it, they gave me a new iPad with new SIM. Tried to register and was told that I could not because the e-mail address was already being used (it was the one I tried to register yesterday which resulted in the H5006 error). Apple suggested I go to an AT&T store since it's really an AT&T problem, but their service was fantastic in replacing my iPad for a new one.
Went to an AT&T store and they person said all that he can do is sell me a new SIM card--that the stores are not able to go into iPad accounts. He seemed frustrated with that inability to help customers, I clearly wasn't the only one who had come in and he'd been unable to help.
Called AT&T, and after two service people, they realized that the H5006 error means that only part of the registration information was transferred and the solution is to delete the account and re-register. Account was deleted, and every time I tried to register I got an "Unable to complete registration, please try later". After several power cyclings and several registration attempts, I was told that a ticket was being written and that I would get an answer on Sept 23--6 days from now. That was a 90-minute phone call.
So, the 3G iPad still doesn't work and it's clearly AT&T's system preventing it from activating. This iPad is for my wife--I have my own 3G and we both have iphones, so we are competent users. The iPad will be returned without replacement if the problem isn't fixed by the 14-day return date.
