11g BPEL Samples

Hello All,
In 10g, we had BPEL samples under the domain with samples, utils and other folders. Do we have similar samples for 11g.
Thanks

Hi,
Samples are not shipped with product in 11g. You can download the samples at
http://www.oracle.com/technology/sample_code/products/soa/index.html
FOD can be downloaded from:

BPEL samples in 11g

What happened to BPEL samples in 11g that would come along with SOA 10.1.x releases...Did oracle not provide them?

Hi,
Samples will not be shipped as part of FMW11g Suite. I guess it will be uploaded to OTN only.

Truncate all Instances in SOA SUITE 11g BPEL SOAINFRA SCHEMA

Hi Guys!
We are running Oracle SOA SUITE 11g + BPEL, Version 11.1.1.3.0 (PS2)
We running out of disk space issues in a database due to large number of test instances in dehydration storage.
Is there any way to TRUNCATE all tables in order to clean up instances from BPEL engine (SOAINFRA schema)
Oracle provides this functionality (purge scripts and implemented procedures in a database) but this is a deleting approach and it doesn't work with millions of instances in a storage. Deleting instances from GUI doesn't work at all.
1. We are looking the way to truncate all instances in a database rather then delete them which takes ages and doesn't work properly in case of huge amount of instances.
2. We would like wipe out all instances without any time restrictions.
Any feedback, script from you guys would be much appreciated.
Cheers!!

Hi,
There still no solution for truncating tables. Looks like we have to look into Oracle's procedures in delivered with SOA SUITE installation.
I posted an article about deleting large number of instances in SOA Suite 11g. It does the job in a pretty fast way.

Java Embedding bug in SOA Suite 11g BPEL??

I am beginning to wonder if there is a 'bug' in the SOA Suite 11g, BPEL, Java Embedding activity? Need some help as soon as possible – does the Java Embedding activity work in SOA Suite 11g?
Have tried the following on Jdev 11.1.1.1 and Jdev 11.1.1.3 – get the same error message (see below for error message).
Thanks for any help - Casey
I created a simple composite app by:
1.     Created a Composite with BPEL Process
2.     Created a BPEL variable by the name of Variable and a Simple Type of string      ({http://www.w3.org/2001/XMLSchema}string)
3.     Added an Assign activity (Assign_1) and assigned the value of “Test Var” to the variable Variable using a Copy operation.
4.     Then, after the assign activity, added a Java Embedding activity (Java_Embedding_1) with Java Version set to 1.5 and the following code:
+try{+*
String var;*
var=(String)getVariableData(Variable);*
System.out.println(var);*
+} // end try+
+catch(Exception ex){+*
System.out.println(ex.getMessage());*

Compiled and got the following error message:

Java Embedding bug in SOA Suite 11g BPEL??

Integration with PeopleSoft Applications Using Oracle SOA Suite 11g BPEL

Hi,
I'm integrating BPEL with Peoplesoft FSCM 9.0 Application on tools 8.49 using Oracle SOA Suite 11g. The BPEL invokes the web service method generated from Peoplesoft Component Interface in a synchronuos manner.
I have deployed the BPEL in Oracle SOA Suite 11g using Jdeveloper successfully but I have problem in configuring the BPEL node in Peoplesoft side using Oracle SOA Suite 11g(FMW) . I had done the integration of BPEL with Peoplesoft FSCM 9.0 on tools 8.49 using Oracle SOA Suite 10g earlier successfully by configuring BPEL node properties as follows:
BPEL CONSOLE : http://Host Name:8888/BPELConsole (System with Oracle SOA Suite 10g server for deployment)
BPEL DOMAIN : default
Using this BPEL node configuration, I was able to ping the BPEL console of Oracle SOA Suite 10g from peoplesoft and hence complete the integration successfully.
Now in order to acomplish Business rules and other functionality, the BPEL application has been developed in Oracle SOA Suite 11g using Jdeveloper 11g. This time I'm not able to configure the BPEL node in Peoplesoft for this integration as I'm assuming there is no separate BPEL console in Oracle SOA Suite 11g. All the BPEL deployments are administered in console (11g console used for deployment of BEPL)
http://Host Name:7001/em (System with Oracle SOA Suite 11g server - Fusion Middleware).
So when I Configured the BPEL node property in Peoplesoft as :
BPEL CONSOLE : http://Host Name:7001/em (System with Oracle SOA Suite 11g server for deployment)
BPEL DOMAIN : default
I'm not able to ping the Peoplesoft BPEL node to the Oracle SOA Suite 11g. Hence I'm not able to proceed with my integration.
When I searched the OTN discussion forum on BPEL console for Oracle SOA Suite 11g, all threads point that there is no separate BPEL console unlike Oracle SOA Suite 10g. Also most of the articles for Integration with Peoplesoft Application using SOA 11g do not state any specific configuration setting for property of Peoplesoft BPEL node in order to integrate with BPEL 11g. The examples published in OTN still point towards screen shots of integration using SOA Suite 10g.
So I'm not able to proceed in this regard.
Any help in this regard is highly appreciated.
Thanks in Advance,
Girish

Hi,
I found this document from the Oracle Open World 2009 (maybe you have found it too) :
"Integration with PeopleSoft applications using oracle soa suite 11g BPEL" --> [http://www.oracle.com/technology/tech/fmw4apps/peoplesoft/pdf/oow2009-bpel-psft.pdf]
And this could be a little more simple, but have a good step-by-step tutorial.
[http://www.oracle.com/technology/obe/fusion_middleware/fusion/soa/BPEL_PS848/OBE_PSFT_BPEL_848.htm]
I think you must read this docs by now, but never come amiss.
Hope this can help you,
By the way, if you can help me with this I'll appreciate it a lot.

OSB 11g,BPEL PM 10g -Does these products has in-built Registry & Discovery

I am looking for options to evaluate Registry and Discovery features for Services developed using OSB 11g, BPEL PM 10g Products. Does these products have these features in-built?
From the product documentation, I noted OSR will provide these features and need to integrate it with OSB, BPEL PM. Without having OSR, can Registry and Discovery features available in OSB 11g, BPEL PM 10g

You have to have a registry in place to manage the service endpoints and have BPEL/OSB discovering them at runtime. BPEL/OSB does not have any inbuilt registry support but they can interact with a registry. Oracle Service Bus can interact with any UDDI 3.0 compliant registry including Oracle Service Registry. You may refer section "4.3 Service Discovery" at below link -

Where can I download working bpel samples from?

When i installed the BPEL PM and Jdeveloper Studio zip from oracle I did not get all the tutorials(i think there are about 75 working samples?). Does anyone know where can I download these working tutorials/samples from?
Thanks!

Hi,
can you please provide the versions of BPEL PM?
You should search for
bpel/integration/orabpel/samples
or bpel/samples
in the application server directory. There you can use tutorials and demos...

Assign one complex element from payload issue in 11g BPEL

Upgraded BPEL 10.1.3.4 to 11g (11.1.1.3.0) and I know the compiler is stricter and all, but I haven't been able to get this working. The requirement is loop through the elements of a payload in a while loop and "do something" with each. Here is a sample of the element structure:
- <ns2:costCenter>
<ns2:costCenterNo>683-01-I/4.3.8.8.04/990000</ns2:costCenterNo>
<ns2:costCenterName>683-01-I/4.3.8.8.04/990000</ns2:costCenterName>
<ns2:level1>683-01-I</ns2:level1>
<ns2:level3>990000</ns2:level3>
<ns2:address />
<ns2:city />
<ns2:state />
<ns2:zip />
</ns2:costCenter>
- <ns2:costCenter>
<ns2:costCenterNo>683-01-I/4.3.8.8.06/990000</ns2:costCenterNo>
<ns2:costCenterName>683-01-I/4.3.8.8.06/990000</ns2:costCenterName>
<ns2:level1>683-01-I</ns2:level1>
<ns2:level3>990000</ns2:level3>
<ns2:address />
<ns2:city />
<ns2:state />
<ns2:zip />
</ns2:costCenter>
I want to pick out one "costCenter" structure at a time. Here is the Assign code that worked in 10.1.3.4:
<assign name="GetCurrentCostCenter">
<copy>
<from expression="bpws:getVariableData('GetAsentinelCostCenters_FindCostCenter_OutputVariable','FindCostCenterResponse','/ns1:FindCostCenterResponse/ns1:costCenter')[bpws:getVariableData('LoopInd')]"/>
<to variable="CurrentCostCenter"
part="FindCostCenterResponse"
query="/ns1:FindCostCenterResponse/ns1:costCenter"/>
</copy>
</assign>
I thought I found the solution when I came acorss the 11g samples and in particular "bpel-102-AssignActivities". I tried the CopyList, which ends up copying over ALL the costCenter elements and "ignores" the LoopInd variable. I tried the simple assign, but get the error about result returns too many nodes:
"XPath query string returns multiple nodes. The assign activity part and query are returning multiple nodes. The assign activity part and query named in the error message returned multiple nodes. It should return single node. According to BPEL4WS specification 1.1 section 14.3, the assign activity part and query named in the error message should not return multiple nodes. Verify the part and xpath query named in the error message at line number 160 in the BPEL source."
I think I've tried every combination that I can think of. I've resulted to posting here in case someone has a similar requirement and has it working in 11g.
Thanks!

Thanks for the prompt suggestions. Both gave me a compile error and I couldn't deploy either. I might try rolling back to 11.1.1.2.0, since I found a similar post for this issue with version 11.1.1.3.0. This process has been running on 10.1.3.4 in production for a year now, so this Assign definitely worked before. I don't know what else I can try.
The Assign works when I hard-code the position, however I get the same CostCeter "/1.6.1.0.01/" assigned every time it goes through the loop, as expected. This has to be a bug in 11.1.1.3.0, it isn't picking up/interpreting the LoopInd variable properly.
<assign name="GetCurrentCostCenter">
<copy>
<from expression="bpws:getVariableData('GetAsentinelCostCenters_FindCostCenter_OutputVariable','FindCostCenterResponse','/ns1:FindCostCenterResponse/ns1:costCenter[1]')"/>
<to variable="CurrentCostCenter"
part="FindCostCenterResponse"
query="/ns1:FindCostCenterResponse/ns1:costCenter"/>
</copy>
</assign>

Error while developing a BPEL sample

I have been trying to implement the GoogleFlowWithSensors sample that comes along with the Oracle JDeveloper BPEL designer. However, when I try to set up the type for the output variable it gives me this message within the variable chooser:
exception: could not retrieve message parts
Anybody knows what seems to be the problem? Thank you.

As I stated in my previous post, there is an issue with the BPEL process not responding back to ESB in a timely manner.
Unfortunately I don't have your process infront of me so it will require some thinking on your behalf to undersatnd how and why this may be happening.
Things to ask yourself.
- Is the data getting past correctly from the ESB to BPEL
- What happend to the BPEL process that the ESB called
- Is the ESB calling the BPEL process you are expecting, check server, and bpel versions
- What does the opmn or domain logs say
cheers

Facing issue in invoking an external webservice from 11G Bpel

Hi,
I am facing an issue in Invoking PIM webservice from 11G soa.. getting the following error in the invoke activity(Invoke calls PIM webservice).. the same thing used to work in 10.1.3.4 where i set username/pwd in the bpel.xml for that partnerlink. here in 11G i did it through "Configure WS policy" and setting oracle/wss_username_token_client_policy to true..

i compared the payload from 10G and 11G the only difference i could find is the order of soap body and header is different.. is it because of this??
i checked in wsdlt the order is correctly declared (first header then body).. but whenever i am creating a variable on this Msg type.. and expanding the variable in jdev the order is getting reveresed.. not sure why?? there is no change in the flow from 10G to 11G.. apart from the migration.

Thanks.. This works..
But it gets lost whenever we redeploy that process..
And of course even though I am seeing http user & http password can be configured in composite.xml.. It is not taking effect..
After redeploy, still the HTTP UserName & Password is blank.

Client is interested in solving only through code not through UI..
Any thoughts..

Using ActiveMQ as JMS Server for 11g BPEL?

I have 11g SOA and ActiveMQ 5.4.1 running on the same Linux server. I would like to configure SOA to be a client of the ActiveMQ server so my BPEL process can receive the JMS messages. I will need to use correlations to get the message to the right BPEL process. I'm not sure how the SOA service performs this task.
We have several 10g BPEL applications that we need to port to the 11g install. They were originally written using Oracle's AQ. If someone knows of a document that could explain this transition, that would be a great help. Also, a document explaining how to configure SOA to be an ActiveMQ client would be of equal great help. I have searched the WEB and haven't found anything, but I have to think this is easier for the 11g WebLogic implementation.

You can register any compliant JMS provider as a foreign jms provider in weblogic and then can access the JMS administered objects (destination and connection factory) from the local weblogic JNDI tree.
This blog shows how to configure AQJMS as a foreign JMS provider and then configure JMS adapter to access the jms objects.
http://biemond.blogspot.com/2009/07/using-aq-jms-text-message-in-wls-1031.html
You can use the above link as a reference on how to setup. You will have to modify the Initial Context Factory, Provider URL, JNDI Properties, foregin connection factories and foreign detsinations section to suit activeMQ.
Note: Weblogic does not come inbuild with the required jars to connect to ActiveMQ unlike AQJMS, so you need to ensure that the active mq jms client jars are available in the weblogic's classpath.

11g BPEL:failure during dehydration when having transformation with 2 input

I'm working on 11g SOA
Has anyone ever seen this problem?. Not every but lots of BPEL process; if I have transformation box that takes in 2 inputs. When I kick off the process, I won't be able to track it in the console, and I found this message printed out on the server unix console.
ORABPEL-05002
error while attempting to process the message "com.collaxa.cube.engine.dispatch.messge.invoke.InvokeInstanceMessage"; the reported exception is: Cannot save xml element. failure to save the element {http://www.example.com/MiddleWare}anytype during dehydration
This element was not a root element and the scope had reference to this element. The scope should have references only to the root element.
I'm not quite understand what does the bold line mean.
Appreciate any help / suggestion .

Have designed the transformation(XSL) using JDEV or handcrafted? What do you mean by 2 inputs, can you be more specific with simple example.

11g BPEL processes -- How-To for day-to-day monitoring ?

hi,
below are some of the day-to-day activities we typically perform in 11g. how to perform these in 11g?
1. switching off-on BPEL processes.
2. Instantiating BPEL processes on demand.. (In 10g, i use dashboad to say initiate)
3. In 11g, i am able to see the audit trail of BPEL instances in dashboard (by deselecting show only running instances), but in instances tab -- I see the composite instances, but not just the BPEL instances.
Any inputs will be useful.
thanks,
Rev

thanks for the resppnse.
i have a problem in #2. In EM, I am trying to test some of the basic processes using file adapter.
TEST button is grayed out and it says 'Only the composites using webserivces can be tested from EM console',
(though this has a workaround by placig a file, trying to simulate what used to happen in 10g)
I am yet to try #1 (switching off-on), One further question:
Is this feature stable even after SOA services restart. In 10g i faced problems in this off-on, after restart process might show 'ON', but might not actually be. I had to toggle as off-on as a workaround. trying to make sure these critical stuffs are fine before planning for prod migration.
thnks,
Rev

Oracle SOA Suite 11g (BPEL Process) Dependency with Database

Folks,
Oracle SOA Suite 11g requires a relational DB like Oracle, SQL Server to maintain the Metadata for the SOA & Related Components.
Can you plz let me know with your experience - what should happen to a running BPEL Process if the database (SOAINFRA) is down? Being very specific -
1, Does/Should end-point become inaccessible? Or Does service remains accessible but throws service remote-fault execption?
2, What happens to a process which is in running state?
My experience in these scenarios is not encouraging; we have notices the following -- during the time when our SOAINFRA database is down, the in-process (running) instances are left in a running state. These instances do not complete or move forward even when the Database is back. These instances do not provide any information in the Enterprise Manager.
Also, if DB is down WSDL's are still accesssible, is this right way?
If this is how SOA does work then I would doubt for its merit……...your thought plz????
Thanks & Regards
Shyam Kumar

I am not posting here because I'm smart but because your questions look interesting.
during the time when our SOAINFRA database is down, the in-process (running) instances are left in a running stateYou know that BPEL is a state-full product and it needs database support for persisting the process of state so if database goes down it is an expected behavior that processes may stuck in the same state where they were when DB went down. I don't see anything wrong with it.
These instances do not complete or move forward even when the Database is back.Instances should auto/manually recoverable. If this is not the case then you may raise a SR with support.
These instances do not provide any information in the Enterprise Manager. What information you could not find? Can you be more clear on this?
Also, if DB is down WSDL's are still accesssible, is this right way?Yes, again it's expected because design time data also gets stored in DB only and hence if DB goes down, any design time data may not be accessible.
If this is how SOA does work then I would doubt for its merit……...your thought plz????Why so? Alternative of DB is physical memory and that I don't think is perfect for long running BPEL processes and their heavy design time data. Moreover, it will create problems in terms of auditing, support and maintenance. If your requirement is such that it does not need any long running BPEL processes and even auditing is not required and use case is simple routing and transformation with no DB dependency then you may go for OSB which is a stateless product. BPEL is generally used for long running processes and hence DB is the best option, in my opinion at least.

Anuj
