Message stack and push BPEL process

Hi.
I found some strange behaviour of BPEL PM.
I have process with 2 receive activities. First to invoke and second for wait to push.
Process have 2 input operation: initiate and push.
When I call process at first with operation push and some correlation id, nothing happens.
But next when I call process with operation initiate and same correlation id, process run out without waiting and looks like receive message with operation push which was send before.
What does it means. What it causes and Can I change this beaviour ?
Thanks

Normal SOA behavior.
It looks like the system gets the push activity, but it can not handle that. So it is stored in the dehydration store. (You should verify that). Now the initiate message is comes is. It starts the process, during the process it should get receive message (push) based on your correlation settings. Now, BPEL is looking in the dehydration-store if it has such a message, otherwise it will wait. But the message was already received, to it continues processing.

Diff Between Oracle BPM Studio and Oracle BPEL Process Manager

1)What is the difference between Oracle BPM Studio and Oracle BPEL Process Manager?
2)What is the connection between Oracle BPM Studio and Oracle BPEL Process Manager?

Hi,
As of today you should install SOA Suite 11g
Fr this you will need to install Database (for development you can use XE)
Run RCU utility to crete DB schemas for SOA Suite.
Install Weblogic server
Install SOA Suite as an option to Weblogic
Create SOA Domain.
It is physically possible to do it in 2GB but is far better on 3 - 4GB
You can consider installing DB on different machine.

Use AQ Adapter Header Message ID Value in BPEL Process

Hi guys,
I'm trying to obtain the value of the message_id in a header variable created in a receive branch activity linked to an AQ Adapter, i've created the variable in the adapter tab of the receive activity and linked the message type variable with the InBound WSDL of the header. I want to use this message_id value obtained in the dequeue operation to set as correlation_id in a future enqueue. The question is, when i do a copy operation in an assign activity of the message_id in the first header variable (dequeue) to the second header variable (enqueue) the BPEL raises an error telling me that the variable was empty, can you help me with this? Am i doing the whole thing wrong? I'm using the 10g version on R3.
Thanks a lot!

Hi Anuj,
I selected "Receive" while configuring B2B adapter. While creating the BPEL process to receive the message, i have created it as Empty BPEL process "Define WSDL later". Then i configured the B2B adapter. In the Empty BPEL process i place a receive activity and wire the B2B adapter. Operation available in Receive activity is "Receive". I'm i configuring wrongly?
Thanks,
Terry

Sync and async bpel process

Hi,
I was reading about the synchronous and asynchronous process in the forum, I have also some similar problem.
some of my questions are:
If suppose my BPEL process is going to take around 2 mins or more to finish , then I cannot chose synchronous BPEL process as the default timeout is 45sec and not recomend to increase the time.
As the above is true, I have created a asynchronous BPEL process, now I want the reply back from asynchronous, is this is possible? even I found that when I invoke the partner link of asynchronous BPEL process it doesn't ask for the output variable. SO if any process going to take longer time and need response from that, whats the solution.
Regards,
Sreejit

Hi James,
Thanks, yes you are correct that receive is required for the response from async process.
Do you have any idea how we can get the response back if we are calling the asyn process outside the SOA server, say from PL/SQL or Java API. PL/SQL can call the sync process and get the response back but in case of async process it returns null as the callback response of async not send the response to database. Is this possible with java api, any link or sample which illustrate this or any step suggestion. Actually I am trying to call the BPEL process from Oracle Apps R12 E-Business suite.

Sreejit

OSB and async BPEL Process

Is there a solution for this problem?

You need to follow below steps...
add a java parameter to the OSB server. Go to domains\osb_domain\bin folder and edit the setDomainEnv file and add this line to this file. set JAVA_PROPERTIES=-Dplatform.home=%WL_HOME% -Dwls.home=%WLS_HOME% -Dweblogic.home=%WLS_HOME% -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0
Step 2 is to replace the bpel jars in the bpel transport ear. Go folder osb_10.3\lib\transports and open bpel10gtransport.ear and replace the following jar files orabpel.jar, orabpel-common.jar , xmlparserv2.jar and oc4jclient.jar with the ones you can find in the soa suite 10.1.3 home.

Hi All,
I am new in BPEL. I need creating asynchronous webservice using AQ Adapter. If any bodies have Enqueue and Dequeue(using Correlation ID) related task please help me.
Thanks and Regards,
M.Sathiya

Hi All,
Enqueue is working good but dequeue is problem for runtime BPEL console . Dequeue done in queue table but can't receive the date from BPEL console the receive activity waiting for asynchronous callback. if i click Interaction(From BPEL console) that given Dequeue Schema field form then i click Post xml message next step going good. My problem is don't wait asynchronous callback receive the data from dequeue then continue the process. If any bodies knows respective set up change or related sample please help me.

How to change the input and output schema in BPEL process

hi',
Please tell me how to change the input and output schema in BPEL process after the process is made.
thanks
Yatan

If your intention is just changing the content you are passing to bpel/returning from bpel
Here is another way
just update your default created xsd files with new elements, update wsdl elements in message definition and chnage bpel code to reflect new elements in activities

Understanding asynchronous BPEL processes and threading

Hi everybody,
I have a question regarding asynchronous BPEL processes and threading.
I have an asynchronous BPEL process which delivers a message (picked up from a JMS topic) to a repository (via for instance an ICAN server). This transaction must be time-sensitive, i.e. first-in is first-out.
If I have several threads running concurrently I have no guarantee that the messages are delivered in the same order that they where generated. It seems that the suggested way around this problem is to use single-threading.
So here's the part that I do not understand:
An asynchronous request does not wait for a response. If I use single-threading then what happens to that single-thread if for some reason (for instance the ICAN server is not responding) the BPEL instance is dehydrated? Is the thread still allocated for waiting for the first response or does it go back and pick up the next thing on the topic? If the next thing on the topic is picked up then how can I be sure that the messages are delivered in the correct order? If the thread is still allocated to the single instance then does that not kindda go against the whole concept of an asynchronous process?
I hope some one can explain this to me.
Thank you in advance.
Kind regards,
Mathias
PS. This question is an attempt of a different angle on another forum thread: Asynchronuos BPEL - how to get the order of messages right?

Hi again,
A quick follow up question:
Is there any way to have several BPEL processes running on the same server with different settings for how many threads to use?
It seems that the only way to set number of threads used by BPEL is to use the configuration in the BPEL console? This is an domain setting - which means that all processes deployed to the server is effected the same way?
I am asking because I am facing a scenario where I need one BPEL process to read from a AQ queue (well actually a topic) with a single thread and another BPEL process - deployed to the same BPEL server - to read from the same AQ queue with multiple threads.
Does anyone have any idea of how to do this? Can it be done?
Any suggestions, hints or reference to any documentation would be very much appreciated.
Thank you in advance,
Aagaard

JHeadstart, Oracle Business Rules and BPEL Process Manager

Dear JHeadstart Team,
I have some questions regarding integration of JHeadstart and Oracle Business Rules and Oracle BPEL Process Manager. As a matter of fact I don't have any work expriences with these tools so my questions may not be good and precise.
1- Using a business rule engine can dramatically increase speed of development and ease of maintenance.I had a very good exprience in using JHeadstart and Headstart in the past but I wanted to know if it is possible to use Oracle Business Rules in conjunction with the JHeadstart ? If so, What steps should be taken? Is there any known issue about this integration? Does Oracle Business Rules have any interference with JHeadstart or it is only used in model layer during insert,update,delete?
2- Is it possible to develope a system based on oracle work flow engine (Oracle BPEL Process Manager) using JHeadstart ? If so, What steps should be taken and how the changes in the flow of work would by applyed in a system developed by JHeadstart. Is there any known issue about this integration?
Any help,link to documents or general guidelines would be highly appreciated.
Thanks in advance,
Navid

Couple of things I would like to add, are the following.
In the context of an ADF application usage of Oracle Business Rules most likely is in the business logic layer, but mind that it does not need to be restricted to that.
Oracle Business Rules takes so called 'facts' as input, evaluates some rules based on that and change those facts or return some result. That might be checking a business rule as defined in the JHeadstart Developers Guide. But it might also return some value that is used in a navigation rule.
Think about a page flow where after page A normally page C is presentend, but in case of some situation (like a customer ordered something and you want to present some special offering based on that) you want page B presented in between (i.e. A -> B -> C). Oracle Rules could be used to determine this page flow. This would be an example of using it in the controller layer (probably in combination with using facts that come from the model layer).
Another remark that I would like to make, is that in my opinion it does not make much sense to use Oracle Rules for business rules that logically more or less are part of your data model (like end date must be on or after begin date). You typically use Oracle Rules to implement business rules that are of a volatile nature, meaning that day-to-day business may require a change of the rules. One example is the navigation case that I mentioned before. Another (typical) example would be a rule that defines when a customer is a Gold customer.

What is the difference between WORKFLOW API and BPEL PROCESS MANAGER API

Hi,
I am using BPEL process manager and would like to know the correct api set.
I found the workflow api which appears to be part of the oracle workflow.
is workflow api and oracle BPEL process manager two seperate products? --- Pls confirm/deny.

Hi me_sun, me_oracle :)
The bpel api can be found here
http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/toc.htm
workflow found here
http://download.oracle.com/docs/cd/E12483_01/integrate.1013/b28985/toc.htm
when us install BPEL you do get BPELs human workflow component. This is different to the Oracle Oracle workflow which was based on the database and PL/SQL.

Error while execution of BPEL processes in IPM Solution

Hi All,
I am working on the IPM Imaging solution in which Invoice data is captured from OFR in XML format , pushed into IPM and then BPEL process is invoked to push the data into apps tables.
I am facing following error while invoking a procedure which is in apps schema from BPEL by giving it parameters.
actually this procedure/function will accept the payloads as parameters and will give some output parameters, but while processing i am getting following error :
Non Recoverable System Fault :
Exception occurred when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'PreImportCleanup' failed due to: Parse struct conversion error.

The invoked JCA adapter raised a resource exception.
Please examine the above error message carefully to determine a resolution.
Any suggestion to get over this issue will be so helpful !
Thanks & Regards,

Hi Nupur,
We had requirement for automating invoice processing, came to know we need to use ODC/ODDC,OFR,OIPM 11g and SOA 11g with EBS.
My questions are:
1. do we need OFR for this.
2. if so how to configure OFR with OIPM
3. do we need to use imaging solution in OIPM for invoice processing and not managed attaachements
4. whts the flow is it frm EBS to OIPM or OIPM to EBS(populate invoice) or viceversa
5. can we do invoice processing automated without AXF solution.
Thanks a lot in Advance,
Ra.

Please advise

you are right the file adapter doesnt invoke any bpel
process, instead it is polling the file from
directory location?If it is polling for new files, shouldn't it create a new instance of the BPEL process automatically the moment it finds a new file? In other words, should a new file trigger an instance of the BPEL process rather than being started from PL/SQL?
Can this file adapter not be invoked as bpel process
in that case?The file adapter is part of a BPEL process. The BPEL process can be invoked from e.g. PL/SQL.
In this case this file adapeter return to an RECEIVE
activity...I think this receive cannot be invoked as
a BPEL process rite?Can you explain what you mean with this?
Also , will all synchronous request return "TIMEOUT"
error, if tried to invoke from pl/sql?Only if the synchronous process instance takes more time to complete (and thus to return) than the value specified for a time-out to occur. If the instance completes in for example 10 ms and the time-out time is specified as 30 seconds, no time-out will occur.

Calling BPEL Process From ESB

Hi Gurus,
I'm experiencing an issue calling a BPEL process using the ESB SOAP Service. Basically, the ESB calls the BPEL process and manages to pass the message to the asychronous BPEL process however the first step in the BPEL process after the Recieve, an Assign, always fails with an Xpath error saying that the attribute being mapped is blank. However, when I look at the Recieve step I can see the value for this attribute. I can Initiate the BPEL process manually and enter the same values and these process successfully.
Has anyone encountered this issue previously or know what I'm doing wrong?
Any assistance appreciated.
Pete

Hi there,
I am getting the same issue. I have two bpel processes, the first processplaces data into a common .xsd format and then sends it over to another process with is expeting the same .xsd format.
I'm pretty sure i know what the issue is, but i'm not sure what the philosophy behind the whole thing is and how it is solved.
When i transfrom the data over to the common .xsd is allocated a namespace ns0 which is then prepended to each element. When this is sent to the other process this stays prepended. The data is then allocated to the common .xsd in the second process with is allocated another namespace ns3.
So when you try an assign is searching for ns3:rootElemnt....... which doesn't exist as it as the ns0 carried over from the first process.
Is this correct? What do we do to get round it?
Thanks,

How to get response from an asynchronous BPEL process in Java

I'm experimenting with BPEL and doesn't seem to be able to get response from an asynchronous BPEL process. Here's the deal:
I have a BPEL process that takes a string as input, and gives another string as output. This is a asyncronous process.
I want to initiate this BPEL process as a web service so I generate a Webservice Proxy in JDeveloper 10g (10.1.3.0.4). The function to call the process is now called "initiate" and takes three arguments: the input string, a "org.xmlsoap.schemas.ws._2003._03.addressing.EndpointReferenceType replyTo" and a
"org.xmlsoap.schemas.ws._2003._03.addressing.AttributedURI messageID".
HTTP-Analyzer shows that invoking the BPEL process with initiate("somestring", null, null) results in sending a SOAP message to the BPEL process, which returns a "202 Accepted". How do I get the response from the process? My intuition tells me that I have to use that second argument, that EnpointReferenceType thing. How do I use that?
Another question: If a asynchronous BPEL process does not exists (so the endpoint does not exist) the Java proxy does not throw an error when runned. It does not even sends a message. It exits with status 0! (This happens for example when deploying a new version of a process and when the "old" version is undeployed). Calling a non-existing synchronous BPEL process, the Java proxy DOES throw an error.

Clemens,
That all sounds logical. But somehow it is still a mystery for me ... Somehow I don't see what should be done.
To call the async BPEL process I have the following procedure:
initiate(String input, org.xmlsoap.schemas.ws._2003._03.addressing.EndpointReferenceType replyTo, org.xmlsoap.schemas.ws._2003._03.addressing.AttributedURI messageID)
The first argument is the input for my BPEL process. The second is the address to a webservice that should handle the callback, right? The third is a messageID (makes sense, but why of the type AttributedURI?).
Here lies my problem. It is not clear to me how these EndpointReferenceType & AttributedURI work. I can't find anything on the net about it. The AXIS examples as where mentioned earlier use other types (namely the "org.xmlsoap.schemas.ws.addressing.MessageID" and "org.xmlsoap.schemas.ws.addressing.ReplyTo") which are completely different.
What I did so far:
- I created an webservice proxy that listens on the onResult endpoint of the BPEL process.
- I created an webservice proxy that calls the BPEL process through the initiate procedure, but it is not completely clear to me how to construct the EndPointreferenceType replyTo, and the MessageID. I did something like this:
EndpointReferenceType replyTo = new EndpointReferenceType();
// callback service running on local machine
// This URI class is the java.net's version
URI replyToURI = new URI("http://vaccinatie:8988/syncro-callback-context-root/stringconcatCallbackBindingPort");
// This AttributedURI is the org.xmlsoap.schemas.ws._2003._03.addressing's version
AttributedURI address = new AttributedURI();
// the only public methos that made sense to me:
address.set_value(replyToURI);
replyTo.setAddress(address);
// call the BPEL process
myPort.initiate("test123", replyTo, address);
But the above doesn't work (largely because I don't know what I'm doing here prob.:-) ) It does send the "test123" message, and the BPEL process does process it, but I don't seem to get the callback right.
I hope this makes my problems somewhat clearer. I hope someone can help me, because I'm just a beginner in this whole "web service area" and seems to do something terribly wrong here, because it should be very simple. Thx.
