Control the sequence of invocation of Partner Links in SOA11g

H!,
I have a BPEL11g process where i am invoking multiple partner links sequentially from my bpel.
Through invoking the partner links i am inserting records in oracle base tables.
The invocation sequence is: PartnerLink1 and then PartnerLink2.
First i invoke partner link1 (web service invoke to another deployed bpel process(db insert)) and inserted records in location table which has foreign key relationship with order_release table.
Then i invoke partner link2 (adapter service:db insert) and inserted records in order_release which has dependency on location table. The second insertion needs first insertion to be successful.
Issue:+ The second invocations takes place to insert record into order_release table before the first invocation of partner link gets completed.
So getting error that corresponding record is not present in location table as it is yet to commit the new record.
Plz Suggest:+ How to stop the invocation of partner link2 to take place before invocation of parnerlink1 gets completed.
a. Tweaking the threads or b. using some partner link property, how i can succeed in correcting the sequence of invocation?

Controlling the sequence of Actions in PA 40?

dear experts,
can we control the sequence of actions executed thro PA 40?
for example , we have the following sequence actions in a client scenario
1. Hiring ( prioritised as 1)
2.probation( prioritised as 2)
3.confirmation( prioritised as 3)
4.change of salary( prioritised as 4)
5.transfer( prioritised as 5)
6.deputation( prioritised as 6)
7.separation (priotirises as 7)
Actually, SAP allows you to run change of salary after probation without confirmation
it allows you to run separation action after change of salary without transfer or deputation in between,
By prioritising actions customisation, system only throws a warning and allows the user to execute any actions after any other action except Hiring action ( sequence no 1)
can we prevent the system to prevent this ,by doing customistion , but without going for any development like hardcoding of sequence
soliciting PA experts advice

hi,
as far as i know there is no such customization.
as such the sequence of actions depend on the clients.
hence they are left independent of each other.
there is no set standard or sequence of actions.
like a person can be hired today can be transferred tomorrow.
for some other person hired today for some reason terminated tomorrow.
one person hired to day next action can be cahnge in pay.
hence i dont beleive waht you are asking for is possible.

How to control the sequence of a map?

Hello
we are using a send email with attachment (map) in our process design, the email body has a few pdf documents, does anyone know how to control the sequence of attachment in the email body?
thanks,

Values in a map are ordered randomly, you can't predict the order.

What is the meaning of resynchronizing BPEL partner link

Hi,
In a documentation regarding BPEL with rules engine I read the following statement:
"If the fact model is edited in the Rule Author, the service definition is affected and the BPEL partner link must be re synchronized."
What does it mean?
How to re synchronize BPEL partnerlink.
Thanks in advance.
Regards,
Phanikanth

Did you explore the help available on the Generic Search Framework in the [ISA Extension Guide|http://service.sap.com/~sapdownload/011000358700000469462006E/]? See pages starting 21, if you have not done so until now.
Make sure if you have maintained the required partner hierarchy.
But if it is a B2B Order status scenario, you would have
either logged in as a contact person to a single sold-to (and hence sold-to determined)
or selected the sold-to already.
in this case, allowing one to change the sold-to will be wrong in the B2B scenario.

How control the sequence in forms

hi all,
i have id column in the form which has to generate the sequence number automatically,i have created the sequence in the database and assigned it and is working fine.
But the problem is that either we save the record or not the sequence is generating.so the as soon as we get in to insert mode the number is generated.
i need the sequence to be generated only when i save the record.
can anyone could help out with the situation.
thanks,
sanjeev varma.s.

hi,
i have already tried it out ,but couldn't get the result.
our problem is that i'm are not able to restrict the sequence, if i'm not saving the record.i have done it in when-validate-item of the previous naviagtion item so that the column on which the sequence is generated can be skipped and sequence is generated automatically.
the below is the code we have tried it out.
DECLARE
v_cname VARCHAR2 (50);
v_com_seq NUMBER;
BEGIN
SELECT NAME
INTO v_cname
FROM company
WHERE NAME = :company.NAME;
IF v_cname = :company.NAME THEN
MESSAGE ('Company name already exists Can not be duplicated');
MESSAGE (' ');
END IF;
RAISE form_trigger_failure;
EXCEPTION
WHEN NO_DATA_FOUND THEN
SELECT COMSEQ.NEXTVAL INTO v_com_seq FROM dual;
:company.CID := substr(:company.NAME,1,3)||v_com_seq;
END;
thanks,

Controlling the sequence of an iPod slideshow using Elements

I'm trying to control the order in which photos are shown in an iPod slideshow (that I'm displaying on a TV screen)
I've been asking how to do this in some iPod forums, and someone suggested (without many specifics) that I could somehow set it up in Elements and then export it to the iPod.
If you know how to do this or can point me to a post, article, etc that gives an explanation, I would really appreciate it! Otherwise, it's all trial and error.

Doesn't it just show files in filename order?

How can I control the node execution sequence?

I have invoked several nodes for controls which are to "Reinit To Dflt". How can I control the sequence of there initialization?

to ensure code (any code) is going to execute in the order you want, you can use some error cluster to controll data flow, so you need your individual code in a subVI with error in and out. Another posibility is to use sequences, but most people will say they hide code, so you can use one sequence only, and pass dummy data from one to another to ensure data flow.
Hope this helps

BPEL Designer doesn't delete the Partner Link wsdl properly

Hi,
In a development scenario; when a partnerlink is created and then deleted, the wsdl file is not deleted. Hence unable to create a new partnerlink with the same service name. Everytime I endup creating a new service name for the partnerlink pointing to the same DB procedure. This will also lead to the change in the other dependent activities like invoke, Assign etc. as the variable names would have changed. These things will make the developement lag behind the time.
Why BPEL Designer doesn't do a clean delete of the all the entries in the xml files and the wsdl file?
Thanks,
Senthil L.

Hi Senthil,
When you delete the Partner Link it will pop a Dialog box asking if you want to delete the WSDL file associated with the Partner link and If you Click Yes then the associated WSDL with this Partner Link is Deleted.
Only the XSD File generated with this partner link are not getting deleted which is being Fixed in the coming Release.
Thanks,
Sunil Gopal

Problem Creating Partner Link for Adapter Integrating with Tuxedo using JCA

Hi All,
This is the first time that I am working on integration tools. I will explain in brief the problem.
There will be a legacy system (Tuxedo) running which connect to legacy database for requests. I am able to connect to that legacy system using Attunity Studio for getting the response back. Which is working fine.
Now I want that to integrate with BPEL PM 10.1.2 using JCA. For this I followed this URL (http://www.oracle.com/technology/tech/java/oc4j/904/how_to/oc4j-jca-tux/onjava-jca.html). What happens here is, a simple servlet invokes a Session Bean that interacts the Attunity Server using the JCA. For that I am using oc4j container of BPEL PM 10.1.2. I could able to work it fine.
For working with BPEL, I have created synchronous process, when try to create Partner link using Adapter service from WSIL browser, it is not coming in.
Am I missed any important configuration at BPEL PM end.
For doing this a followed the "tutorial 2" @ http://www.oracle.com/technology/products/integration/adapters/dev_support.html
In exact way, above provided tutorial 2 PDF, I failed at step "Configuring a BPEL Service to invoke the above Adapter Service" on page 11.
Your help is highly appreciated
Thanks
Venkata

Something to note. I tried adding the same BPEL services as partner links to a new application and new project on two other developer's workstations, and the creation of the partner links were successful.

Modify all partner links of a process

hello,
what i am thinking about is to modifiy all partner links used in a process.
As described in the cookbook you can change the endpoint reference of a parnter link throug an assert statement.
What i did up to now is to look up the partner links through the api. I have the names of the partner links, etc now in my process workflow stored in a variable. Iterating over the links works fine. Now i want to get and afterwards modifiy the endpoint reference of every partner link in the process. To fetch the information about the endpoint reference of a partner link i tried to use a statement like that:
<assign name="assign-1">
<copy>
<from partnerLink="bpws:getVariableData('link')" endpointReference="..."/>
<to variable="partnerReference"/>
</copy>
</assign>
the link variable holds the name of a partner link.
Of course that didn't work :)
The BPEL4WS spec. 1.1 says that the from-spec has to look like that
<from partnerLink="ncname" ......
That would mean that there isn't a possibility to bring any dynamic in that expression
Any ideas on that?? I mean can i dynamically fill the from and to expression....
Greets Jens

There is a whitepaper out that describes dynamic functions for adapter out, I believe the pdf is named bpeltechadp.pdf , search for that on metalink.

Why we use Dynamic Partner Link in BPEL process

hi,
What is the purpose of using Dynamic Partner link in BPEL process ?

Hi Shankari,
apart of using the the config plan you can change the endpoint uri in runtime if you define the property "endpointURI" in your composite
<binding.ws port="http://xmlns.oracle.com/bpel/workflow/taskService#wsdl.endpoint(TaskService/TaskServicePortSAML)"
location="http://localhost:7001/integration/services/TaskService/TaskServicePortSAML?ORAWSDL"
soapVersion="1.1">
<property name="weblogic.wsee.wsat.transaction.flowOption"
type="xs:string" many="false">WSDLDriven</property>
<property name="endpointURI"
type="xs:string" >http://localhost:7001/integration/services/TaskService/TaskServicePort</property>
</binding.ws>
then right click your composite in the enterprise manager and go to "Service/Reference Properties". There you can change the endpointURI property.
You can also change the endpointURI inside your BPEL process. Go to the invoke inside the bpel process and go to the "properties" tab. There search for the property "endpointURI" and set a value.
hope this helps
cheers Nicolas

Setting encoding/charset when invoking a Partner Link

Hi,
I'm having a problem with setting the encodign when calling a partner link from a BPEL-process. Default charset seems to be utf-8, but I need to set the encoding to iso-8859-1. I've tried using the contentType-property under partnerLinkBinding, but with no success. Any ideas?

I also got a similar error when i tried to use WSIF binding in BPEL. My BPEL process invokes a WSIF webservice and gets the result. The error i got is below,

Difference betwee "Binding" and "Partner Link"

Hi Forum - Could you please explain the difference between Binding and Partner Link and when to use which one?
Thanks!

Thanks for the explanations. Can I create a service with just the SOAP binding without usnig BPEL partner links in Oracle BPEL?
I have tried this however BPEL is adding a reference to my WSDL and then creating a partner link by itself in the reference binding. How can I stop it from doing that?
The reason I want to do that is becasue I have a BPEL project which has two processes, which I expose as web sevices by creating the WSDL file manually (not using auto wizard).
I have deployed this project on weblogic soa domain but its giving me two endpoints for it and two links to wsdl file, one for each process. Is this normal?
Thanks!

Linking control of the effects timeline with the sequence timeline

This should be simple but I can't work out how to do it. Either Premiere CC lacks this obvious feature or I'm an idiot (don't answer that)...
So here I am, editing some effects - let us for example say I want to stick in a very fast audio fade-out and fade-in to mask out some noise. I want to zoom in close on the effects timeline so that I can finely adjust the exact position of the keyframes.
The zoom slider on the effects window is fiddly and doesn't automatically centre on the frame currently selected in the sequence, so keeping track of it and finding it once zoomed in is really difficult. Zoom control on the sequence timeline doesn't present these problems.
SO, as I'm sure there is a good reason why my effects timeline and sequence timeline are not normally linked is there a way of forcing this so that when I zoom the sequence the clip (if selected) in the timeline?
Am I making any sense?
All advice (other than 'Have you tried turning it off and on again?') gratefully received.
Howie

Because Premier allows you to look select clips for review in the Effect editor that may not be at the location of the cursor on the main sequence timeline I can see why it wouldn't be helpful for the two timelines to be synchronised by default but it would be useful if it could be enabled for those of us who like working that way. I am forever adding effects to the wrong clip.
My biggest problem is that with some clips, when I try to zoom in on the effect timeline I cannot get it to zoom in completely to give me the ability to move keyframes a frame at a time easily. Sometimes it'll let me zoom in to the max, other times it won't... it's very frustrating.
I admitted defeat earlier and asked one of the online advisers to look at it for me. They couldn't make it work on some projects either.
Oh well.
