OSB Split-Join problem

I am a bit confused as to how to design a split-join via Oracle workshop for weblogic
I have imported a WSDL and can define how to decode my incoming request so that I can issue multuple service requests via a Parallel node
When I try to configure the Invoke Service node - I can't sem to reference anything other than the WSDL I started with ???
I thought I was supposed to be able to access any other Business (or Proxy) service (or even another Split-Join)
Don't know if this is clear enough for anyone to be able to help

When you configure Invoke Service you can choose any WSDL-based business or proxy service operation. Under Input Variable and Output Variable tabs you set message variables of appropriate types.

Aggregating output of two BS in OSB Split join

Hi,
i am using split join to invoke two BS and after the each invoke activity in parallel branch i have placed assign activity and assigning output variable of in voke to reply activity output variable response.parameter . However in o/p i am getting response of only one BS. can any one help on how to aggregating output of two BS in OSB Split join . my output is coming like this
<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
<soap-env:Body>
<ns2:NewOperationResponse xmlns:ns2="http://www.example.org/SjWsdl/">output</ns2:NewOperationResponse> -------->this is o/p of one BS. But i want to display O/p of two BS
</soap-env:Body>
</soap-env:Envelope>
thanks in advance..

Suppose you saves the response of each BS in variables: $response1 and $response2
then you need to configure the replace action after the parallel branch like this:
Replace node content of . in variable <variable name of reply variable> with <Expression>
Where you can provide in <Expression> a simple XQuery expression to combine the two variable contents. (Choose a root node of your choice, I have used AggregatedResponse)
<AggregatedResponse>
{$response1, $response2}
</AggregatedResponse>

OSB Split Join Repeat Until Question On XPath Condition

I'm trying to use OSB File Transport to stream a very large XML document file into a service which will split the file into very many small XML documents. So, given a file like:
<BookStore>
<Book></Book>
<Book></Book>
... (many more books)
</BookStore>
In the split join I want to use a 'repeat until' to process each Book until there are no more Books in the BookStore. Here's my question: What is the correct XPath expression to use as the Repeat Until terminating condition? (I'm an XPath novice.)
Thanks for your help!!!

Hi,
Based on what I understood, you should be using a for each loop with the conditions as follows:
Within the Split Join flow
for each ( counter variable from 1 to Count (xpath of book) ) --> For my example it was count($request.parameter/sjpoc:Orders/sjpoc:Order) replace this with your xpath.
- do your logic
Snapshot just in case @ http://dl.dropbox.com/u/19901533/sj_foreach_snapshot.JPG
Based on this the split and join would happen for n (based on count) number of Book tags.
Let me know if my understanding is incorrect.

OSB SPLIT JOin How to verify it is working parallel

HI ,
I am using Oracle service Bus 11.1.1.3 and I have following Requirement
PS 1 : Receives the request ,validates the input and calls proxyservice 2 (using publish action )
PS 2[Sb ] :Receives the req from Proxyservice 1 queries a DB using the DB Dapater and obtains a list of subscribers for the request .
Each item of the list contains information about the subscriber metadata(data format,JMS endpoint) .For Each Subscriber calls Proxyservice 3 which the subscriber meta data info and the actual request received .
PS 3 [SB ]: Receievs the subscriber meta data and the actual request XML .depending upon the format specified in the meta data for the subscriber performs transformation(using xquery) and post the transformed xml to the subscriber specific queue [JMS ].
Proxyservice 3 is common for all subscriber depending upon the metadata different Xquery needs to be called for different subscriber [this is achieved using Dynamic xquery ].
My requirement is i need to call Proxyservice 3 in parallel for all subscriber .
OSB doesnot out of the box provide action for spanning multiple threads of a PS from another PS .
I have tried using Split join .Have created a Split Join which will loop through the list of Subscribers returned in PS2 and call PS3 for Each loop (have specified paralle =yes in split join ).
How do I confirm that PS3 is called in parallel for all the subscribers .
Is there any other way I could implement this requirement of spanning multiple threads ?
Thanks a regards ,

HI Abhinav ,
Thanks a lot for the help .I had tried with adding log actions at various places.
Added a log action as the first action of the for loop (split join )
Start of PS3 and End of PS3 ..

For each sample example in OSB without Split join

Hi,
Any body have sample example for For each in OSB without Split join......Thanks in advance

I know this is an old thread, but I just ran into this same problem. Wow! That's a crappy 'feature'. I wasted 4 hours this morning on this thinking it was me doing something wrong in my xpath, but nope, you need to cast the counter to an int .......
I hope they fix things like this in the next major release.
Thanks for the solution.

Dynamic Split Join:Parallel flow using OSB

Hi,
I am implementing a dynamic split join in OSB,where in the for -loop i am invoking a database adapter.
If I select parallel='yes' in the for-loop settings, I get a random number of records from the database as an output.
While on the other hand, on running the for-loop sequentially, i get the exact number of records i am expecting.
Could anybody figure out why is this happening?
Regards,
Tarun

If I understand correctly, this is what you are doing:
Configure a For loop based on a repeating element in source XML (for ex. for each customer id in xml message).
Inside each loop you are making a DB lookup and getting one record for each element (for ex. customer details of each customer id)
Finally you are aggregating them in the same variable (join)
The problem that you see is that if you do it in parallel then you do not see details of all customers in the out variable?
If yes, then can you please let me know how you are updating the details of each record in the out variable.

Problem with variable inside split-join

Hello,
I'm using Oracle BOM Suite 10.3.0.0 and i want to use the split gateway.
In general the split activity ends with a join.
the problem is when i affect a value to a variable between the split and join, it could not get this value after the join, which means after the join the variable becomes empty just like it was before the split.
could anyone help me please.
thanks

HI
Case 1: Instance variables are not shared:
At join you can copy the variables from one of the branches to the main instance (that waits at join).
this.instanceVar = copy.instanceVar
This will copy the value of variable 'instanceVar' from the instance that just arrived at join to the instance that was waiting at join (main instance)
Case 2: Instance variables are shared:
This would mean that the main instance shares its variables with the child instances (instances between split - join). In such a case, when a variable is updated by any of the branches, the change is reflect in all the copies.
You can set the property to share or not to share instance variables, in the advanced properties of the split activity.

Can anyone help on this?
Thanks in Advance...

maybe this one helps a bit, it's the same pattern
http://www.xenta.nl/blog/2011/07/03/oracle-service-bus-implementing-aggregator-pattern-by-use-of-split-join/
if you're using a dynamic split join easiest way is to do something like
assing <yourresponse/> to $response
at this moment your assign an empty placeholder to the response variable
now you go into the for-each looping and for each iteration you need to insert the response of your bpel call in the $response variable
so in the looping as last step you add something like
insert $mybpelresponse/rootelement into $response/yourresponse
with the insert it will insert the reponse 1..x times into the $response variable (so actually aggregating all the responses for you)

Split joins in OSB

Hi,
Actually i do have a requirement where i need to call 2 business services simultaneously(in parallel) in OSB(Like using Flow activity in SOA) using split joins. Is it possible to call 2 business services parallely in OSB?
Can any one please help me out with any blogs or steps that i can follow to achieve this.
Your help is appreciated.
Thanks,
Naveen

That is not entirely true. Split Join itself is based on single operation, i.e. the input to split join will be a single message, but within the split join you can invoke multiple services in parallel. You can either dynamically decide the number of parallel flows at runtime (similar to FlowN) or you can have static number of parallel calls (like Flow activity of BPEL) within split join.
In case you want to call two business services in parallel, create a WSDL(if needed, in most cases you can reuse the WSDL of the Proxy Service itself for SplitJoin as well unless you are doing enrichment within Proxy before calling business services) for split join which has request message which contains data for both business services. Within the split join you can configure calls to both business services in parallel and you can also add transformations for each business services in respective branches.
You can than aggregate the response from both services if needed and return that as a response of split join.
Here is an example of Static Split Join:

Split-Join, unable to set SOAP:HEADER in OSB at Invoke Service Component.

Hi Experts,
i created a Split-join for parallel processing and invoke third party services, but this service requires some mandatory elements in soap:header like WS-Addressing and, WSA-TO and some security infomation, but i don't know how to pass header in invoke service step. Please help me to setup Header for Invoke services in split join.
Please help me to resolve this issue.

not the most fancy way, but you can create some sort of wrapper proxyservice in front of your business service to make it work

How to set SOAP Header When Calling Business Service (OSB) Using Split-Join

Hi,
We need to call WSDL based webservice which requires heading static content for successful call. As we need to call the same service parallely, hence we want to use Split-Join.
Looked at couple of forum links, noted that we can't play with headers while working with Split-Join.
For curiosity, just want to check any option other than using proxy as mediator in setting header information.
Regards
Venkata Madhu

Venkata,
You still have the option, if you hv n't tried this one.
To enable this capability, you must declare the header parts along with the body parts in a single request/response message in the Split-Join WSDL and in the WSDL of the proxy or business services invoked by the Split-Join. With the message parts declared in the WSDLs, SOAP header content is available to Split-Joins in the request/response message variables.
Following is an example of the message and binding definitions in the WSDL.
Message
<wsdl:message name="retrieveCustomerOverviewByIdRequestMessage">
<wsdl:part name="retrieveCustomerOverviewByIdRequest"
element="co:retrieveCustomerOverviewByIdRequest"/>
*<wsdl:part name="serviceContext" element="sc:serviceContext"/>*
</wsdl:message>
Binding
<wsdl:input>
<soap:body use="literal" parts="retrieveCustomerOverviewByIdRequest"/>
*<soap:header message="tns:retrieveCustomerOverviewByIdRequestMessage"part="serviceContext" use="literal"/>*
</wsdl:input>
hope it helps !!

Error in Split-Join when invoke similliar B.Service with same namespace

Hi Guys,
I having a split-join that doing parallel spliting call out to business service. And i encounter this error.
Severity and Description Path Resource Location Creation Time Id
Error compiling the Schema Type System: error: sch-props-correct.2: Duplicate global type: GetabcParam@http://www.xx.xx.abc (Original global type found in file: null) SplitJoin.flow line 1 1265267604208 5245
Can I know is this a limitation of the OSB or is a Bug? Or there is a more better way to implement this?
Edited by: kpchong on Feb 4, 2010 7:51 AM

I'm not sure if this is a known limitation or a bug. I faced this issue once, but needed quick fix so I didn't contact Oracle support at all.
I remember that the problem emerged in case I had a SplitJoin with Parallel action and both branches used WSDL-based business services whose WSDL files imported the same (shared) XSD file. As I wrote before I needed quick fix, so I ended with re-adjusted namespaces just to overcome this issue. Ugly but effective.

Split/Join, Invoke Service and SOAP Header in osb10.3 wls10.3

Hi gurus,
Are Split/Join able to invoke external services with a custom SOAP header?
I have a split join to call 2 external business services in parallel. Those 2 external services requires a custom SOAP Header
<soapenv:Header>
<v1:ConsumerRequestHeader>
<v1:requestSessionID>TEST_1</v1:requestSessionID>
<v1:requestTimestamp>2011-06-16T16:57:54.943+02:00</v1:requestTimestamp>
</v1:ConsumerRequestHeader>
</soapenv:Header>
All WSDLs were configured by the instructions of this link : http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/eclipsehelp/tasks.html#wp1150628, but in my debuging, the SOAP header is disappeared when calling those external services from the splitjoin. (No problem if designing and testing with the ProxyService. but Proxyservice is useless here because of parallel processing)
When designing with OSB Workshop IDE, there is no way to pass the custom SOAP header to the "Invoke Service", only the body request/response message.
My question is, Split/Join automatically uses its header to pass it into the invoke call ?
Please advise...
Thanks,

Invoke secured service through Split-Join

Hello,
I create a new Split-Join (in the OSB workshop application). Then
I use an action "Invoke Service" to call a not secured business service. So far no problem. When I assign a security policy to my business service, the OSB does not accept. Here is the error message in the OSB workshop:
[Parallel, Scope, Invoke Service]
The WSDL Binding for BusinessService "OSB/1_0/BusinessServices/TestBS" is not supported: The service feature "WS-Security" is not supported.
How can I call a secured business service in a splitJoin?
Thanks

Well, another way is a custom WSDL.
The problem, I believe, is not the PS or BS by themselves, but the WSDL Split-Join "sees" from them. So, if you make a version of the same WSDL with no offending policies and supply it to Split-Join, it should work. I suspect you'd still have to build the intermediate PS with that stripped WSDL though.
In fact, forget about PS. Strip the policy from WSDL and add them to the BS from a policy resource. I would believe Split-Join in this case will not see the policies, while BS would use the ones configured for it.

Passing header to split join BS

hi All
My proxy1 calls a split join BS which in turn calls 2 other proxy services(proxy2 and proxy3).
The problem is that the header passed from proxy1 to split join BS is not passed to proxy2 and proxy3.
note: I've confirmed that the header is passed from proxy1 to split join BS.
Any ideas on how to pass header from split join to other proxies ?
Thanks
Ross

Given the use case of SplitJoin in OSB, it works with the body only and does not give options to play around with the headers.
You will have to introduce to intermediary proxy (IntProxy1/2) between the SplitJoin and proxy2/3. And you can have the logic of inserting the header in this IntProxy1/2. This way the header is passed on.
You may want to refer Oracle Service Bus 10.3 - split join how to set header for invoked service
