Correlation in mediator

HI All,
I have a Synchronous mediator component calling asynchronous BPEL Service component.
Can anyone let me know how the mediator performs correlation of BPEL Callback responses?
Thanks

If you are thinking about correlation sets then I would say that it is BPEL specification feature and available only in BPEL. Mediator does implicit correlation for async request/callback scenarios.
It would be helpful if you can explain the usecase you are trying to achieve.

Sandeep

Async process

hi,
i have a question. if u have a async process then u send several request and u may or may not receive response immediately.
Then, how can soa infrastructure relate - whenever the response does come "Which response is meant for which request" ? How does it relate correct response to the corresponding request ?
is it taken care by soa infra automatically ? or does developer need to do specific in bpel to correlate ? any good doc on this requirement appreciated.
thx

quick amendment to the previous post - in case your service does NOT support ws-addressing you can use the correlation set feature in BPEL (content based correlation). Mediator (in 11g) sets its own correlation id into the request.

How to design to perform for a network mediation correlation application?

we have three network devices, each producing text based logs for their own activity. each node can start a traffic and each node can be an end. but a traffic here can mean going back and forward on nodes. and we are intrested to report the each traffics start end nodes, like a CDR we may say.
I have imported the data of each node to a table, but this is not mandatory, in order to have the required output I can easily denormalize the target tables, similar to a ETL of a DW.
If I have the data in three seperate tables I suppose I will need to implement a recursive pl/sql function, since the data is ~250 million rows per day to have a performant process to find the start and end points of each traffic what kind of a table design and as a result SQL or PL/SQL algoritm do you advise?
any example code you may be aware of pipelined pl/sql feature used recursively?
thank you.
ps: for the current test environment we have 10.2 installed on solaris but we can easily decide to use 11.1 if there is any special motivation for this need.

You could dig through the docs and try to figure out the file format manually, or you could do this the easy way. Simply use the Outline Load Utility to export your attribute dimension from Planning. The export file format is the same as the import file format. You might have to manually add a couple of test members to your attribute dimension so that your export file has some content. Then simply update the file you exported, and import it.
(I am assuming you have already manually created the Attribute dimension in Planning, and that you simply need to add members to it.)
Hope this helps,

Content Based Correlation in Oracle 11g

Dear Veterans!!!
I am working on the following use-case.
An order processor accepts order(Mode-Buy/Sell, Price, Quantity) on webservice from various customers, and presents them to DecisionService, after adding the order Id to it. The decision service would check if the price*quantity > 1000, if so the response is sent as (Order ID, OrderStatus="Fail") else, sends (Order ID, OrderStatus="Success").
What I want to do?
Now I need to create Order Processor using single JMS Adapter with Interaction type "Asynchronous Request/Reply" using content based.
What I have been able to do?
I have been able to do content-based Correlation between Decision Service BPEL and Order Processor BPEL, where Order Processor has two JMS Adapters, One Producer which enqueues the order for Decision Service, setting the orderId as correlation. The another JMS Adapter is set as Consumer and recieve activity is registered with it and picks up the response after correlating the message.
Also I have been able to do the "native correlation" scenario, using Decision Service as mediation module.
What is the problem?
1. I need to have the decision service as BPEL, and be able to do the native correlation, which I wonder how to do, because the Jdeveloper 11g has removed support for Adapter Header variables.
2. I need to use decision service as BPEL and be able to do the content-based correlation, using a single Asyncronous Request/Reply JMS Adapter instead of two (Producer and consumer).
Any Pointers shall be useful.
Many Thanks,
Regards,
SwapSawe.
I am aware of how to set the correlation
http://swapnil-soa.blogspot.com/2008/01/correlation-this-post-would-effort-to.html
And how to do it in Oracle 11g

Edited by: SwapSawe on Nov 30, 2009 11:01 PM

Dear Friends,
If I was not able to make my point clear, I would explain it again. I am posting message from one BPEL process to an Asynchronous Request/Reply JMS Adapter.
A consumer JMS Adapter, would read the message from Q and would initiate another BPEL process, which would perform some business logic to generate a response and post it to reply queue via JMS Producer.
Now the reply posted, is picked up by the Async Request/Reply, but the receive activity is unable to correlate the message.
I was able to do this scenario using native correlation, i.e. JMS Message Id mapped to JMS Correlation Id, through mediation module. But I am looking forward to do this using content based correlation.

SwapSawe

Implementing Correlation in BPM 11gR1

Hi,
Need urgent help for implementing correlation in Oracle BPM 11gR1.
Scenario: A busines process has various steps.When the request for the Step 1 comes, the BPMN process is instantiated which in-turn calls a sub-process that completes that step. After its completion, need to keep that thread waiting till the request for Step2 is received. When the request for Step 2 is received, need to re-start the waiting thread by corelating these two requests (Based on a unique ID).
Now the ques are:
1. Can we implement correlation in BPM 11gR1?
2. If yes, how?
3. If no, what is the alternate approach? (Think,can use BPEL corelation sets. Can anyone provide the steps for the same?)
Any inputs around this would be really very helpful,thanks.

Hi,
You can achieve this behavior using BPMN, BPEL and Mediator components within a composite. We use this approach in a recent project. I wrote a new post in my blog explaining how to do that: http://blog.andrade.inf.br/2011/01/implementing-correlation-in-bpm-11gr1.html
I hope this can help.

Correlation set was not defined in the process

Hi All,
I deplyoed a synchronous CustomerProviderABCS on SAO 11g server.
This process is invoking the Adapter service(mediator) which internally calls the SAP Adapter.
I didn't define any correaltion sets and I am not using pick activity.
After deploying the Provider I am getting the follwing issue:
java.lang.Exception: oracle.sysman.emSDK.webservices.wsdlapi.SoapTestException: Correlation definition not registered. The correlation set definition for operation SyncCustomerParty, process default/SyncCustomerPartySAPProvABCSImpl!2.2*soa_33303a8b-c115-4a93-b338-094e4a4c4078/SyncCustomerPartySAPProvABCSImplProcess, is not registered with the server. The correlation set was not defined in the process. Redeploy the process to the container. at oracle.sysman.emas.model.wsmgt.WSTestModel.invokeOperation(WSTestModel.java:575)
I tried by redeploying the process multiple times.
any workaround please........
Thanks in adavance.

I don't know what happened to my server but now I am getting same issue with all my BPEL processes and earlier same process were working fine and I tired to use SOA-DIRECT and then this issue came but I removed it but still same issue and then I created new simple synch process but same issue is coming ......looks like need to change some config or some setting somewhere....please help if anybody have any idea?
Thanks a lot in advance...

Reading MSQueue Correlation ID in BPEL

Hi,
I have an inbound JMS queue adapter which keeps polling to a queue. As soon as there is a message in the queue, it will be picked up by the JMS adapter and it will be given to the BPEL process. I can access the queue message through the "inputvariable" in BPEL. However, I also need the correlation ID in BPEL flow since I need to put it back into another queue along with the processed message.
Can some one help me how do I get the correlation ID in this case?
I know how to access it if I have a mediator. But I don't want to use mediator between queue adapter and BPEL.
Let me know if there is a way of doing this.

Correlation set based on correlation from raised ADF event payload

Hi,
In a BPEL process, how can we include a Correlation set based on correlation from raised ADF event payload ?
Thanks

Hi Charles,
Thanks for the response.
Actually, my requirement is : I have a BPEL Process which has a pick activity. The OnMessage branch of the Pick activity is mapped to a service which is invoked by a Mediator. This Mediator is Subscribed to a Create Event.
I am able to run my BPEL and Mediator instances separately but the problem is even though the Mediator is invoking the webservice, after the Create Event is raised, BPEL 's pick activity is not getting the response from the webservice due to which BPEL continues to be in running state.
This might be a problem with a Correlation Id seting .
How can i make by BPEL process know about the Mediator instance ? Any idea ?
Thanks
Nutan

How to make a Mediator deal with calling an external Asynchronous Service

Hi,
Using TP 4.
I want my Mediator to invoke an Asynchronous Service that is external to the composite application. But I do not know how to get the reply from that service back into my Mediator.
I have worked with the sample of calling an asynch BPEL component within the same composite - that is fairly easy to accomplish.
What how can I tell the external service to invoke a callback porttype on my Mediator. Can the SCA container work out the correlation between the external service and the correct instance of the SCA composite? Should the Mediator publish the callback interface as an external service at the SCA Composite level? If so - how would the correlation work? If not, how does it work?
Any suggestions - even the statement that I always need a BPEL component in between that will support correlation with external asynch services, if that is the case - will help.
Thanks.

Kylie, welcome to the discussion area!
Cable modems behave differently than DSL modems in that they will "remember" the last device that they have associated with. Your modem is "remembering" your MacBook and when you connect the TC, the modem won't connect because it "remembers" the MacBook.
You need to make the modem "forget" a previous device whenever you make a change in the device that is directly connected to the modem. Here's how:
Push the reset button on the modem if it's present
Pull the power cable on the modem
Pull the battery from the modem if it is easily accessible
Leave the modem powered down for 25-30 minutes
Power down the rest of your network as well
After the wait period, connect the modem to the WAN port on the TC with an ethernet cable
Power up the modem first and let it run for 3-4 minutes by itself
Then power up the TC the same way
Power up the rest of your network the same way
Depending on how you had your TC configured with the DSL modem previously, you may need to make a few changes in the settings.
Post back on your progress.

Did you know about "Arbitration and Mediation" FAQ?

I have just made a discovery that many of you frustrated Verizon customers will be very interested in knowing about. Did you know that you can type in legal action in the search verizon.com box and you will find a category called "Arbitration & Mediation" FAQ? For those of you, like myself who have been dealing with months and months of issues with Verizon and you are getting nowhere, you might check this out. It is very interesting.This may have saved me hours and hours of time and some over the top emotion that our situation has caused.

Proper names are known. But product names will not be - nor will acronyms.

Correlation Rule where no accountId on resource

Hi experts ;-),
I have a resource with no accountId, but Employee Number as primary unique identifier. I have written a correlation rule to match this employeenumber to an extended user attrib also called employeenumber (previously populated from a file load).

Check for Null in Mediator Static Routing filter

Using Expression Builder for Mediator component how can I check the values for NULL in a particular XML element. In my case the XSD is
<xs:complexType name="OdsCadDataSet">
<xs:choice>
<xs:element name="odsCadCase" type="OdsCadCase" minOccurs="0"
maxOccurs="1"/>
<xs:element name="odsCadEvent" type="OdsCadEvent" minOccurs="0"
maxOccurs="1"/>
<xs:element name="odsCadUnitStatus" type="OdsCadUnitStatus"
minOccurs="0" maxOccurs="1"/>
</xs:choice>
</xs:complexType>
I want to check in expression builder of mediator whether odsCase, odsCadEvent, odsCadUnitStatus is been processed. I have three static routing for each element and plan to put filter which checks is odsCadCase is null and so forth. How to have this use case.
Thanks

Source code for 2d cross-correlation fx?

I know this is a long shot but does anyone have the c or c++ code to compute the 2d (image) cross-correlation fx? (I know that IMAQ VISION has the cross-correlation routine but I am looking to potentially modify the 2d correlation routine to compute something called non-symmetry coefficient and would need to start with the source code). Or, labview source code for this operation would also be quite acceptable and in fact preferred!!
Thanks,
Don

I don't have the 2D cross correlation in labview, but... isn't the cross correlation very similar to an FFT? In that case a 2D FFT could maybe help since it shows how the 2D FFTs are derived from 1D FFTs in labview. I attach an llb where 2D FFT is done. I don't know where I got it from, maybe I even wrote it myself sometime in the dark past (probably translating it from some piece of C source code from the 'Numerical Recipes' book).
Maybe it is of some help for you...
