How to Transactional Processes in BPEL

Hi,
TestCase:
I have some BPEL processes which needs some Transaction Processes. These process can be DB process with Multiple insertion/selection/retrieval.
I could see the 'scope' process activity however I would like to know that:
1) Is there any alternate way to define Transaction/Isolation level or any other Transaction related parameters?
2) Is there is any way that I could set Transaction related parameters in 'scope' process activity?
TIA
regards
JD

Hi,
the transaction behaviour is not related to the scope activity...
The transactions are defined on the db connections which are defined in the webservices.
I think there is no way to use distributed transactions via webservices... (At least there is no documentation for this...)
If i am wrong, i am very interested in a concept of using 2 PCs in Oracle BPEL/Webservices....

The above procedure will be defined as concurrent program in Oracle EBS.This concurrent program will call the bpel process.My question is how should i design the bpel process so that bpel will know it is called by a concurrent program?
My BPEL is doing picking a file by FTP adapter and inserting data into a table.
Please throw some lights on this!!

Option 1:
You have to design the service as a synchronous BPEL process
1. Do a synchronous ftp get to read the file.
2. Transform and write it into database table
3. Reply results back to plsql
Disadvantage: Your BPEL process should complete from BPEL timeout happens.
Option 2:
1. Enqueue the message into AQ from the concurrent program
2. From the BPEL monitor the AQ, start the process when the message arrives
3. Do a synchronous ftp get to read the file.
4. Transform and write it into database table
You cannot reply the results back to concurrent program.
5. However, you could have another AQ to send the results back to concurrent program.
6. Your concurrent program should listen to the resultsAQ to get the results back from BPEL.
Option 2 is a relliable design.

How to call a Asynchronous bpel process from a PLSQL procedure?

How to call a Asynchronous bpel process from a PLSQL procedure?

Hi,
You could do something smart and technical very spiffy with soap-stacks in the database and/or dbms_ws/dbms_http. But I allways find AQ with AQ-adapter the simplest. Let Pl/sql enqueue a message on an aq-queue and subscribe an aq-adapter process on it. That can call your async-bpel process. If you want to get answer back in pl/sql, let the aq-adapter process enqueue a response message on another queue or on the same queue with another consumer name. Give it a correlation-id that you provided in the payload of your request message. Your pl/sql process can then do a dequeue on that correlation-id. It will sit and wait until a message with that correlation id is enqueued on the queue.

How can i implement a Transaction Processing procedure in my web app ?

Im planning to enhance my web app servlet.
the web app is about Online Banking.
since it is Online banking, there would be time where simultaneous user accessing their account. mean several connection is made on my db.
I read some article about Transaction processing, so i think it is wise for me to
implement on my web app but i not sure where to start and in what way can i integrate it with my web app.
here are several thing i have in mind..
making the admin able to monitor , or better if can coordinate the transaction.determine the network traffic on my web app. etc.
any advise or wise opinion please ..thank you for time reading too.

How to start working with BPEL[SOLVED]-but someone still can help me :)

Hello Everyone,
I'm Fizzz, I'm totally new to BPEL. I don't know where to start and how to start.
Right now I'm Working with JDeveloper 11g R1. I didn't go further yet but Now i have to create some BPEL Process that can be integrated to my Web Application. There are some transaction to be Approved or Canceled from BPEL and if Transaction is Approved then i need to Update that Transaction to Peoplesoft's Database. I have 1 week to learn it. and then i need to start my work.
But i really don't know where to start? What do i need? And how to proceed?
Can Anybody suggest me the steps that i can follow to get Start with BPEL and done with Peoplesoft connectivity?
I would really appreciate your help.
Thanks,
Fizzz...

Thanks user11082822 and Vivek..
Your Oracle Doc links are really very helpful. i would definitely go through these docs to get familiar with BPEL, But i have only one week to understand this part of technology.
So would request for any Live Example or How to's for Sample BPEL app creation and integration part of that. I would definitely read these document but i need some fast overview on these processes practically.
Can you please suggest me such things.
Thank you very much to both of you for your very quick and very helpful effort. :)

Question : Scheduling a Long Running Process in BPEL

Hi All,
I have a doubt regarding deployment and scheduling of a Long Running Process in BPEL console like the way we schedule a concurrent program in Oracle Apps.
Business Scenario:
We have developed a BPEL process to pull data from the Database, do the required transformation and then enqueue the transformed data in a queue present in another database.
Then a Java program will pick the data from the queue and then generate an XML file and send it to FTPserver of the Trading Partners(TP's).
We have two Trading Partners and hence the generated XML will be put into the appropriate FTP servers of the TP's.
The BPEL processing for both the Trading Partners is identical. Only the generated XML is put in different FTP servers.
My question here is:
1. Since the processing is same for both the TP's, how can we use the same process for both the Trading Partners.Can we handle it in the BPEL process itself ?
2. Is there any way to schedule the same process in BPEL console, to first run for Trading Partner TP1 and wait for say 15 mins and then run for another Trading Partner TP2 and this cycle should continue since we will be deploying it in production environment and continuous updation of the transactions will be happening in the database.
So far my knowledge in BPEL goes, i could not find any way to schedule a process in BPEL console. If any one has come across similar scenario, please post your updates/approach which will help us in defining the architecture for our client.
Thanks In Advance,
Cheers
Dibya

Hi Marc,
Thanks a Lot for ur inputs.
Need some more clarification for quetsion no.1 in my previous post.
From our BPEL process we are calling a package which takes the Trading Partner name as the input and some other parameters. Our BPEL process will be run for both the Trading Partners since the processing is identical.
If we develop two different processes for both Trading Partners, then there will be locking issues in the database since both the processes will refer to the same table.
Hence we were looking for an option where we can use the same process for both the Trading Partners. Is there any way to handle it in BPEL process.
Your inputs will be really helpful.
Thanks In Advance,
Dibya

How can we process the CRM Order again for second time in debugging mode

Hi,
Can anybody please tell me how can we process the CRM ORDER for second time. that I want to process in debugging mode.
Thanks,
bsv

Hi bsv,
Are you trying to reprocess a BDOC for debugging purpose?
If the BDOC is not with a final status, you will be able to reprocess it using the reprocess button in the smw01 search result list.
And you may put /h on the popup when you click on the 'reprocess' button.
If it is allowed to make some changes in the CRM ORDER for testin purpose, it would be easier to perform debugging.
A more 'careless' way is to deactivate the outbound or inbound queue in transaction smqs or smqr, then in smq1 or smq2 to locate the interested queue, and click on button 'debug LUW'.

Transaction Process not rolling back

Hi Experts,
I am testing the Transaction Process which uses a DB Adapter (which calls a procedure) to insert data into a table. There are 2 fileds in the table (employee id and employee name) and in this employee id is the primary key. In the same scope I invoke this DB Adapter PL twice and for the first invoke it went fine but for the second invoke it has thrown me a unique constraint exception (as again I am passing the same data). I am catching the exception with a catch all block which is working absolutely fine.
The problem is in the table I am getting the data entry for the first invoke which should have roll backed as i am using the *'transaction=participate'* property and respective changes have been done in bpel.xml for supporting the transaction.
There should be no entry in the table but yet I am getting it. Please help me.
Where could I have gone wrong?????
I am using BPEL-10.1.3.1 version.
Thanks in advance.
Cheers,
Ankit
Edited by: user11083689 on Apr 24, 2009 4:41 AM

hi,
There are two mechanisms to force a rollback from a BPEL process.
Explicitly — throw a bpelx:rollback fault within your flow:
<throw name="Throw" faultName="bpelx:rollback"/>
Invoke a partner link that marks the JTA transaction for rollback only.
For example, in Oracle SOA Suite for 10.1.3.1.0, if Oracle BPEL Process Manager invokes an Oracle Enterprise Service Bus (ESB) flow that in turn fails to call a Web service endpoint, the JTA transaction is marked for rollback. Since the Oracle ESB flow enlists its local transaction in the JTA transaction, a rollback on the JTA transaction impacts Oracle BPEL Process Manager's ability to dehydrate (as the JTA transaction is used by Oracle BPEL Process Manager for persistence).

Transaction (Process ID 477) was deadlocked on {lock} resources

hi !!!
Has anyone encountered the following error:
java.sql.SQLException: [Microsoft][SQLServer JDBC Driver][SQLServer]Transaction (Process ID 477) was deadlocked on {lock} resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
My prgram contains many thread which Update the database, the same table but different rows.
Thanks and Regards,

This problem relates to the Microsoft SQLServer, the server has decided to decline the request from that instance due to an internal deadlock issue. Your instances request was arbitrarily chosen as the one to terminate. So the SQLServer sent an error status back that would have been passed on thru the ODBC bridge to the JVM and then to your application.
How you want to handle this event within your app is up to you.

Item Category usage & Main Item Category(Transaction Process)

Hi Friends,
Can you help me to know the details of Item Category usage & Main Item Category in Transaction Process.
I couldn't able to find the usage of these, while we are assigning Transaction type, Item category group, Item category usage & Main item to the Item category determination, the system is taking Transaction type data from Leading transaction type & Item category group from Product master data, then what is the use of Item category usage & Main item, where we need to maintain these details in system, Is it mandatory?, How come we know this is mandatory while doing configuration?..........
Can you let me know the use of Item Category usage & Main Item Category in Transaction Process.
Thanks & Regards.......
Arun

Hi Arun,
Item category usage is mailnly used for text items not for products..
its not all mandatory.
In item category determination only Transaction type, Item category Group and Item category is mandatory,
The main item category is necessary only when ur lower level item is dependent on ur higher level item.
For more Info read the documentation in SPRO.

PePe
