Transaction management in App module

Hi -
I have a scenario where my db operation needs to participate in the distributed transaction. This operation will be called by a SOA service. So, i have created a custom class and custom method in my application module and exposed that as service interface. Now assume that a SOA service is making 3-4 sequence of calls to some other external systems. In between it is calling my custom method as well. Like
step 1) call to extenal system 1
step 2) call to external system 2
step 3) call to AM's method exposed through service interface.
step 4) call to extenal system 3.
In the above scenario, if any one of the call fails, SOA service has to rollback all the steps. In such scenario, can the AM's custom method (3rd step) participate in the transation and rolled back when 4 th step fails?
Thanks & regards
Aravindan

Thanks for the response.
In the oracle documentation (section 11.3.7 in http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcextservices.htm), it has been mentioned that "remote call is stateless, and the remote service will not participate in the same transaction as the business component that uses a service-enabled application module's service interface"
"If you successfully call a remote service that results in modifying data, and then subsequently your local transaction fails for any reason, then it is the responsibility of your error handling code to perform a *compensating transaction* against the remote service to "undo" the previous change made"
any thoughts/suggestions?

Transaction control of app module implementation , from a SLSB

Hi, We are using a Session bean , to invoke app module implementation - service methods to manipulate VOs.
The service method of app module is having control of transactions , like commit . We want to have this control from stateless session bean.
Could some one help me ? Thanks .

Hi,
expose a custom client method on the ADF BC module and have this method (in AM impl) calling commit.

Transaction Management - App Module in Stateless Session Bean

Hi All,
We are using Application Module in local mode in a Stateless Session Bean. The application module gets the database connection from the datasource of the application server(Oracle 9iAS).
The problem that we are facing is as follows
- When a database update/insert is made using the Application Module and the ViewObject (and the underlying Entity Object), the changes are not being commited.
Please note that we are not using the ApplicationModule.getTransaction.commit() as it does not give us commit/rollback control from another Session Bean/UseCase. We instead are relying on the Container to manager the transaction and commit the database changes. But the container does not seem to refresh the changes to the database.
Q1 - Is there a contract between the container and the application module that needs to be created so that the container managed-transaction and the application module work together ?
Any help in this matter would be greatly appreciated.
-Ankur Sinha

Q1 - Is there a contract between the container and the application module that needs to be created so that the container managed-transaction and the application module work together ?For stateless beans you have to call postChanges in the business method for the changes to be applied to the db. For stateful beans bc4j we do that automatically just before the transaction ends.
Take a look at the following howto
http://otn.oracle.com/products/jdev/howtos/bc4j/ejbstateless_with_bc4j.html
In 9.0.3 you'll be able to create a stateless service bean declaritively.
dhiraj Hi dhiraj,
- I looked at the example but was not able to find the ContainerManagedTxnHandlerImpl class in the BC4J jars. Can you point me to the latest version of BC4J on technet ?. I already have JDeveloper 9.0.2
- Regarding your response, what do you mean by creating stateless service bean declaritively ?
Thanks,

App module view object row currency and task flows

Hello -
Using JDev 11gR1. My application uses ADF Rich Faces with ADFBC.
I have case where I want to
a. select a row in a table based on a view object
b. hit a button to invoke a method in an application module.
c. in the app mod method, call getMyViewObject().getCurrentRow() to get the row selected by the user
d. "do something" with the row
In 10.1.3, this worked fine.
In 11gR1, I am having problems:
1. The above situation works fine if I have a regular page.
HOWEVER,
2. The above situation does NOT work if my table is in a page fragment in a task flow. (The getCurrentRow() returns NULL.)
For case #2 I've checked the following:
* verified that the selectedRowKeys and selectionListener attributes were set on the table in the page
* verified that I'm using the correct app module instance (I have nested application modules).
* experimented w/various transaction and data control scope settings in the task flow definition.
So... from those details is there something obvious I am doing wrong? It looks like cases #1 and #2 above use different row set iterators. Is there a way to grab the correct row set from within my app module method? Does this have something to do with the data control scope defined by the task flow? (For 11g do I need to "rethink" sticking logic in the app module and instead placing it within a managed bean get access to my ADFBC objects via the bindings layer?)
Thank you for reading my question,
-- Scott

Are you planning to use this AM as a nested AM inside other application modules?
If you don't the "selection AM" will have its own, separate database connection/transaction.
If you do, it will share connection, transaction with its containing "root" AM.
It may not be relevant to your application, but just realize (which is explained in the article I point to above) that view objects that are not related to entity objects do not "see" pending changes in the current transaction. That feature depends on the VO/EO cooperation. It's fine to build VO's without an EO -- in fact we've made it easier to do this in 10.1.2 in the Design Time wizards -- but you just want to make sure you realize what features it's giving up. If you don't need those EO-related features, then by all means create an Expert Mode VO that's not related to EO's.

Separate App Module, View Object based on Select not EO: Best practice?

Hi,
I have a list of base tables(parameters) that are used everywhere in my application for selection components (List, Combo, Radio).
I'm considering creating a separate app module with a view object based on query for each table.
I have created a BaseTableAM application module for managing those tables, Entity objects and View Objects in update mode.
Those tables are rarely changed.
Example of table:
ItemType
item_type_id = primary key
name = description
In the BasetableAM:
ItemTypeEO entity object
ItemTypeVO updateable view object based on related entity object.
Now in my project I will create combo boxes for selection of the item_type_id.
Separate application module:
SelectionViewAM composed of View Objects based on Select statements and not on Entity Objects.
Example of view object ItemTypeViewVO:
SELECT ItemType.ITEM_TYPE_ID,
ItemType.NAME
FROM ITEM_TYPE ItemType
All view objects in this application module will be read-only and for selection only.
By basing all those View Objects on select statements not based on Entity Objects I suppose there will be no locking and "value changed" management => less overhead.
Is this a good practice?
Being read-only I could have based those View Object on Entity Object with flag updateable set to no, what would you recommend?
By creating a separate Application Module for those selection view objects, I know that update will not be possible.
Thank you for your advice.
Frederic

Need to Return immediately and commit the App Module on a different thread

I have an action that I want to return fast (immediately) but the server processing takes longer than acceptable. The results of the operation don't matter to the page submitting it and I want it to be able to navigate away even if the operation is not complete. I want to either be able to send a non-blocking server event from the browser or on the server side start a new thread that performs the operation allowing the original thread to return immediately. The new thread would need access to an Application Module in order to commit data. How would I go about accomplishing this?
Some thoughts
I've tried creating a ConcurrentLinkedQueue and putting the DataControl on the que, then in the other thread I pull it off the que, process and commit the data. This works unless the page is navigated away from. Then calling dc.getApplicationModule(); returns null.
I thought about using createRootApplicationModule in the new thread (since the new thread has no context) but don't know how that would work
This is the code in the run method of the new thread. In this example, I'm adding data to the app module in the original thread and committing the data in a new thread.
(like I said, it works most of the time.)
Object[] req = (Object[])que.poll();
DCDataControl dc = (DCDataControl)req[0];
try{
ApplicationModule am = dc.getApplicationModule();
if (am != null){
am.getTransaction().commit();
} else{
System.out.println("AM:null unable to commit ");
} catch (Exception e){
e.printStackTrace();
finally{
if (dc!= null){ dc.resetState();} // release app module
}

Thanks for the replies. I am aware of the inherent risks of running a separate thread within a managed container.
The use case is a performance logging operation. We have a internal web app used by a network of franchises with over 1000 users. We log response time and performances statistics to the database. When the user clicks to navigate or commit data, the response time that the user experiences is logged after the page has fully rendered either through a PPR or a full submit. This is done by submitting ADFCustomEvent from javascript on the page after rendering is complete.. The event sends up the time difference from when the user first clicked to when the page was fully rendered. This information is then merged with logged events stored on the users Session that shows the name and response time of every query that was executed during the previous request. Depending on the page this could be up to half dozen to a dozen or more queries. The logging operation as experienced by the browser is generally fast (<200ms) but sometimes can be as long as a second or more when the database gets busy. A half second is too long as makes the app appear sluggish if the user can't type or click immediately after the page has finished rendering. The logged data is aggregated so we know exactly how much of the page load was due to a slow browser/network, how much was database time, webservice call time, etc... If it's due to a slow database we can drill down and see which query is the culprit. These performance metrics are critical to operations and are charted throughout the day so we know exactly what our users are experiencing. All of our users use a custom firefox client that we control. Using this logging framework we were able to determine that upgrading to a Firefox 4.0 based client cut browser render time by more than half a second on average. We can also tell what type of hardware the user is running so can place the blame for poor performance where appropriate. We have determined that pages render considerably faster on Windows 7 than on Windows 98 with the same hardware. We are moving the logging tables off of our exadata database to a separate box to remove that load from the application database. Since we expect the other database not to perform as well we don't want it to affect the user experience, hence the need to log asynchronously. I would like to put the data on a queue and have a background daemon process read from the queue and commit to the database. I would like the daemon thread to be able to use BC components. I would prefer not to resort to using a web service because of the inherent overhead. The logging operation is not a long operation but is of high frequency so should be as streamlined as possible. The load is spread over 6 servers with 4 JVM's each (24 weblogic instances). I know it's possible to use BC components from a plain Servlet (which runs on it's own thread) so what I want is to have something like a servlet thread that loops forever processing my logging queue.
One other method I am investigating is using my own non-blocking ajax call that callls a servlet to perform the logging. I will need to pull out the timestamp contained within a client side ADF component along with the pages ctrl-state variable that is included with every ADF request as it uses this as the key to get to the data on the session. ADF really needs a non-blocking ADFCustomEvent for this type of request. (send and don't care about the response)
The client component with the server listener looks like this
<af:outputText value="#{pageFlowScope.perfClientTS}" visible="false"
id="perfClientTSField" clientComponent="true">
<af:serverListener type="logPerfData" method="#{perfLog.logPerfDataAction}"/>
</af:outputText>
The script that queues the ajax call after the page loads looks like this
AdfCustomEvent.queue(perfClientTSField, "logPerfData", {
typeId : typeId,
subTypeId : subTypeId,
responseTime1 : new String(responseTime1),
responseTime2 : new String(responseTime2),
openedVia: via
true);
I also tried calling the noResponseExpected() method on the event before queuing it but it still blocked the UI and caused an additional side effect in that the client sent two ajax requests instead of one. It somehow thought something on the client side needed to be synced with the server.
email me and I can send a doc with more details about how our performance logging framework works.

11g TP2 ADF Task Flows and Transaction Management

I'm wondering how ADF Task Flow Transaction Management works vis-a-vis database sessions and using stored procedure calls in an environment with connection pooling. I haven't written the code yet but am looking for a better understanding of how it works before I try.
Example:
I create a bounded adf task flow. I set the "transaction" property to "new-transaction" and the "data control scope" to "isolated".
As the task flow is running, the user clicks buttons that navigate from page to page in the flow. Each button click posts the page back to the app server. On the app server a backing bean method in each page calls a stored procedure in a database package to modify some values in one or more tables in the database. The procedure does not commit these changes.
Each time a backing bean makes a stored procedure call will it be in the same database session? Or will connection pooling possibly return a different database connection and therefore a different database session?
If the transaction management feature of the adf task flows guarantees me that I will always be in the same database session then I don't have to write any extra code to make this work. Will it do that or not?

I don't know if it is documented in the adf documentation currently available for 11g TP2 but what you ask for is a normal transaction management with connection pooling and i can't imagine it is not implemented in ADF BC layer like it is in JPA or other persistence layer.
A transaction will always be executed in the same session. Normally your web session will stay in the same session even you start more than one transaction. You don't have to write any code to manage the session pooling. It is a good practices to customize it at the persistence layer during installation depending on your infrastructure.
Take a look into Fusion Developer Guide ... i'm sure you will find some better explanations about this.

BAPI's for Transaction Manager: Is there any BAPI for Stock Options

Hi gurus,
We are using almost every BAPI for Transaction Manager module at FSCM-Treasury & Risk Management (ECC 6.0).
We have forex swaps, forex forwards, forex spot deals, interest rate swaps, cross currency swaps, equity swaps, and we also have a stock options plan.
We need to use a BAPI to automatically create stock options, importing data from other stock options alreaedy created (manually, by the user) in the system.
Do you know if there is any specific functionality for this?
Thanks in advance and kind regards.
Borja

Hi Borja,
if I understand you correct then you want to create a stock option like you can do it manually with the transaction FWZZ. Try the BAPI BAPI_FP_CREATEFROMDATA. With this function module it is possible to create different types of securities like listed options or futures too.

Java user-defined transaction management not working correctly???

Hi everyone,
I have encountered a problem when using Java user-defined transaction management in my session bean. It threw an exception but I could not work out what that means. Could anyone comment on this? Thanks.
This BrokerBean is a stateless session calling other entities bean to perform some simple operations. There are 2 Cloudscape databases in use. Invoices (EB) use InvoiceDB and all the other EBs use StockDB.
If I comment out the user-defined transaction management code, then everything works fine. Or if I comment out the Invoices EB code, it is fine as well. It seemed to me that there is something wrong in transaction management when dealing with distributed databases.

Three things:
first, maybe you should think of putting ut.begin() just before the invoicesHome.create() method and ut.commit() just after the stockTrans.remove() method.It wont solve the current problem but will help in performance once the problem is solved.
second, your utx.commit() is outside the try block. how come the code is compiling then??
third, try doing a SOP call before and after invoicesHome.create() method and see where the problem actually lies.
let us know...
Hi SteveW2,
Thanks for being so helpful. Here are my replies:
Can I just ask why you're not using containermanaged
transactions?The reason why I didn't use container managed
transactions is because I don't really know how to do
that. I am more familiar with this user-defined
transaction handling.
I have attempted to implement the same method in an
entity bean and just let the container manage the
rollback itself. The same exception was thrown when
running the client.
Also, the transaction behaviour is likely to relateto
the app server youre using - which is it?What do you mean by the app server? I am using J2EE
1.3.1 if that is what you meant.
Finally, if your code has a problem rolling back,and
throws an exception, you discard your exception
thereby losing useful information.I have tried to print the exception stack as well, but
it is the same as just printing the general
exception.
This problem is very strange cause if I comment out
the transaction management thing, then everything
works fine. Or if I am only working with 1 single
database, with this user-defined transaction handling,
everything works fine as well.
Here is the error log from J2EE server if you are
interested.

Nesting App Modules from ADFLibs - jdev 11.1.2.3

Hello:
I have a dashboard application with 6 tabs. On each tab is a bounded task flow from an ADFLib. Note: each BTF has its own App Module.
In the Master DashBoard App, the ADFLibs BTF's are dropped as regions in each tab. The Master App has its own application module and I want to nest each of the BTF App Modules under the single App Module in the Master app. The reason is that each tab of the application currently creates a seperate DB connection. I want the Master App to only create one DB connection for the entire application.
In the resource pallet, I can see the App Modules from the seperate ADFLibs, and I have added these App Modules to the Master Project, but the newly added AM does not display under the Master App Module for me to nest. (in App Module ->- Data Model --> Application Module Instances)
How can I nest multiple AM's from ADFLibs under a single Master App Module? ( the AM from ADFLibs do not display in Application Module Instances in the Master App)
Thanks

Have I added the application Modules to the Master Model?
Answer:
In the Master, In the Resource Pallet, I highlighted the Application Module in the ADFLibs (from Subsystem), right clicked and selected Add to Project. But this did not make the App Module display in the Master App Module Application Module Instances. (Note: my subsystem adflibs are deployed from ViewController with dependency on Model. I tried to hightlight App Module above and add to Model Project of Master in above) This caused WebLogic to fail to deploy.
What is the correct way to add an App Module from an ADFLIb subsystem and add the AM to the Master App so it displays in the Master App Module Application Module Instances?
All subsystems should use the same connection and all subsystems are set to No Controller Transaction and Share data controls with calling task flow is checked for all subsystem.
More testing revealed:
One thing to note: each of my subsystem, a deployment profile was created on the ViewController with dependency on its Model project. When I added the subsystem project above to add the AM, I adding the App Module from the adflib to the Model project of the master. This caused WebLogic to fail during deploy.
So I tried another test. In the subsystem, I created another deployment profile, on just the Model project and created an adflib. I added this new adflib to the Model project of the Master. The App Module from the subsystem now shows up in the Application Module Instances. (which I selected and moved over to the right to nest under Master App Module. This time the application ran, but still have one connection per tab.)
Do you create ADFLibs with a deployment profile on the VC with dependancy to the Model Project? Or do you create two seperate ADFLibs for subsystems, one for VC project only and one for Model project only?
Thanks for the help.

Accessing an app.module's client interface methods in other app module

Hi all,
We are developing an application with number of projects (one for each module). We have got a common project with an application module, entity and view objects which are common for the entire application. For reusability, this common project is shared in session scope since most of them are of static nature.
In the shared application module's implementation class, a common method has been included that will be used for data filtering by constructing/appending where clauses in a particular application scoped view object. This method has been exposed as client interface method so that other projects can make use of it. The common project is compiled as an ADF Library jar for accessing it in other projects.
For accessing the exposed client interface method, from the view controller layer, we can include its reference in the page definition file and can execute the method from a managed bean by finding the operation binding from the page definition. But, in case if we wish to access the method in another model project, we could not do so.
Now, my questions are:
1. Is it the correct location(Shared App Mod. Impl) for including the logic to filter the data?
2. Is it possible to access the app. module impl method in another project's impl classes (Let it be entityImpl or viewObjectImpl or viewRowImpl or AppModImpl) ?

Receiving Transaction Manager concurrent program errors out with INACTIVE, NO Manager

Hi,
We have an R12.1.3, 2-node (1 node Apps, 1 node DB) ERP system on Sparc 64, Solaris 10 Machines.
All the concurrent managers including Standard Manager and Receiving Transaction Manager are running fine.
When we are running the concurrent program Receiving Transaction Manager(RCVTPO), it errors out with Inactive No Manager error.
I am not being able to find any errors in the log files of CM or DB.
Could someone help me resolve this error. Its kinda urgent
Thanks.
Muneer

Please see the solution in (PODAMGR And RCVOLTM Inactive And Cannot Be Started (Doc ID 726158.1)).
Are there any errors in the database log file?
If the above didn't help, please run cmclean.sql and ccm.sql scripts.
Concurrent Processing - CMCLEAN.SQL - Non Destructive Script to Clean Concurrent Manager Tables (Doc ID 134007.1)

Con. Req. 'Receiving Transaction Manager' Inactive/No Manager : This request is an unconstrained request. (queue_method_code = I) , No concurrent manager is defined to process this request, so it cannot be processed.

Hi Gurus,
I need your help on a concurrent request ( Receiving Transaction Manager ) showing as Inactive/No Manager.
EBS: R12.1.2 on Linux
Database: 11.2.0.3 on HP UX Itanium
A user is submitting the concurrent request - "Receiving Transaction Manager" (It is a concurrent program not a concurrent manager). The request ends up as Inactive/No Manager. When I click on the diagnostics button this is what it shows -
"No concurrent manager is defined to process this request, so it cannot be processed.
Contact your system administrator to define a concurrent manager to process this request or to verify that existing concurrent managers have the correct specialization rules."
I ran analyzereq.sql and the analysis is
Analysis:
Request 1427025 is in phase "Pending" with status " Normal".
                           (phase_code = P)   (status_code = I)
This request is an unconstrained request. (queue_method_code = I)
It is in a "Pending/Normal" status, ready
to be run by the next available manager.
Checking managers available to run this request...
There is no manager defined that can run this request
This should show on the form as Inactive/No Manager
Check the specialization rules for each
manager to make sure they are defined correctly.
Additional information (from apps.FND_CONC.DIAGNOSE):
No concurrent manager is defined to process this request, so it cannot be processed.
Contact your system administrator to define a concurrent manager to process this request or to verify that existing concurrent managers have the correct specialization rules.
I ran another SQL to find out which manager runs the program :
select CONTROLLING_MANAGER,request_id
from fnd_concurrent_requests
where request_id=1427025;
It returned blank (or) NULL for controlling Manager.
select b.USER_CONCURRENT_QUEUE_NAME from fnd_concurrent_processes a,
fnd_concurrent_queues_vl b, fnd_concurrent_requests c
where a.CONCURRENT_QUEUE_ID = b.CONCURRENT_QUEUE_ID
and    a.CONCURRENT_PROCESS_ID = c.controlling_manager
and    c.request_id = 1427025;
Returned Nothing.
I thought that for a concurrent program when no specific manager is defined, Standard Manager is the default. Is my understanding wrong ?? Have anyone of you faced this issue? How did you fix it ?
I did check the profile - Concurrent: Conflict Domain for the responsibility and it is blank.
Appreciate any help.
Thanks
Cherrish Vaidiyan

Was this working before? If yes, any changes been done recently?
Your understanding is correct, unless this concurrent program is excluded from being processed by standard manager.
If the request was not processed then the no rows output is an expected behavior -- (Doc ID 344011.1)
Have you tried the solution in (Doc ID 1303315.1)?
Thanks,
Hussein

My session beans are stateless and i use container-managed transaction management(cmt)
And my application server is glassfish 2.1
How can i use this problem.
Thanks for your reply.

Do you have org.netbeans.modules.* classes referenced in your code?
Those IDE classes are (correctly) not available on your container so you should consider not using them in your code.
