Functionality of IF in OSB message flow

Hi Team,
am just confused about the functionality of IF in OSB message flow, either in a proxy or in a split-join.
for example consider the following scenarios in if-then stage,
1. I write the condition as status="yes", then some process will be done.
2. but what if I write just status? what can be the functionality of IF here?
Please suggest the needful thanks in advance.

but what if I write just status? what can be the functionality of IF here?
Then the $status variable is evaluated. If it is not an empty sequence (), it is considered true (AKA exists).
In other words, if there is anything in the $status variable, it is true. Unless it is a boolean false, of course, but all variables in OSB are strings, so that is not going to happen.
Please note that Split-Join AKA Flow is a different codebase. Its variables are typed (vs strings in OSB), and hence if will behave differently for false value.

How to convert XML to Binary in OSB Message flow

Dear All,
Can you please help me in converting XML to Binary in OSB Message flow.
Please help.
Thanks,

ah ok, then you have to apply a transformation from XML to some fixed length format, EDI style
probably you have 2 options: the traditional MFL
http://docs.oracle.com/cd/E13159_01/osb/docs10gr3/consolehelp/mfls.html
or the (probably) more supported nXSD with a JCA adapter
http://docs.oracle.com/cd/E23943_01/integration.1111/e10231/nfb.htm
I will let you digest this info and then we can continue.
There are a number of threads in this forum on whether one technology is better than the other (as usual, google can assist you)

Replacing default namespace in OSB message flow

I'm in the process of setting up a simple OSB proxy and could use some help figuring out how to change a default namespace in the response from the business service.
The proxy and business service use different namespaces which we'll call "http://foo.com/namespace/proxy" and "http://foo.com/namespace/business". In my routing request message flow, the contents of $body look like this and I'm able to use a Rename action with XQuery expression "./sof:*" to change "http://foo.com/namespace/proxy" to "http://foo.com/namespace/business":
<sof:Execute xmlns:sof="http://foo.com/namespace/proxy">
<sof:adminName>MyAdaptor</sof:adminName>
<sof:request>
[escaped payload omitted]
</sof:request>
</sof:Execute>
This works fine, but in the response message flow, I need to revert the namespace and am having difficulty because the response uses a default namespace instead of using a prefix:
<ExecuteResponse xmlns="http://foo.com/namespace/business">
<ExecuteResult>
[escaped payload omitted]
</ExecuteResult>
</ExecuteResponse>
If I define a prefix P2L in the expression editor to correspond to "http://foo.com/namespace/business", I'm able to reference the ExecuteResponse element as "./P2L:ExecuteResponse", but then I get stuck.
If I try use a Rename action to change the namespace for "./P2L:*", only the ExecuteResponse element is renamed to <sof:ExecutResponse xmlns:sof="http://foo.com/namespace/proxy">. Upstream in the calling application, there's an XML stream reader exception because (I assume) ExecuteResult is not found and parsed.
I also tried using a Replace action against "./P2L:ExecuteResponse/@xmlns" to replace its contents with "http://foo.com/namespace/proxy". I also tried "./P2L:ExecuteResponse/@P2L:xmlns". Neither worked.
Can anyone tell me what I'm doing wrong, or suggest a different approach? Assume that changing the calling application or business service is not an option.
Thanks!

You pattern "./P2L:\*" matches just one element so it's ok that the payload's namespace wasn't touched. If you want to rename namespace for all elements try "//P2L:*". However, I'm not sure whether this is what you want. Try do describe what you do, what you want and what you get instead.

I think it's not a good approach to replace content of xmlns as this attribute is not a common xml attribute.

Adding alert activity in OSB message flow urgent

hi,
i added an alert activity in my OSB proj message flow to monitor the process . after deploying the proj in console, i gave inputs. but i am not able to see the alert in operations>dashboard>pipeline alerts . no alert has been written in dashboard.
i have mentioned the alert destination, for alert logging option i have selected yes. can anyone pls hlep he in this issue.
thanks

Did you enable Pipeline Alerts in the Operational Settings tab of the Proxy? If yes, also select the appropriate level based on the Alert level you had set within the message flow.
Also check the in the SB Console > Operations > Global Settings , that the Enable Pipeline Alerting is selected.
Thanks,
Patrick

WS addressing inside OSB Message Flow

Hi There,
We are trying to work with the ws-addressing structure inside the Message Flow of a Proxy Service, but i don't know how to define in the wsdl to see the structure of the ws-addresing in the Header, i need to see it to obtain some values in the "Assign" task of a Message Flow.
Can you help me in this issue?
Regards
Yuri

ws-addressing is supported in conjunction with WS transport.You should attach a required policy

How to retrieve MQMD Header in OSB Message Flow Pipeline

Hi ,
My Proxy Service is reading a non-xml message from MQ-Queue . The format of the message can be different , which is recognized by a MQMD header : applicationType . Putting application populates this header .
I want to get the value of this MQMD header , in message flow ,to decide which MFL file needs to be applied . But the problem is that "Transport Headers" Action header gives only option to add new headers , not to retrieve the existing ones . Please help me.

You can access the MQ transport headers in the assign/replace actions using the relative xpath of the $inbound variable. This is available for any transport.
Please find a snapshot @ https://dl.dropboxusercontent.com/u/19901533/access_inbound_mqheaders.JPG
Also ensure that you configure the Get All Headers property+ to yes on the Transport Configuration of your proxy.
Thanks,
Patrick

How to do Async call in OSB message flow

I am calling a service from OSB layer synchronously and when this service gives a response, I am forming another request with this response and storing it in a variable now I want to call another service asynchronously by using this variable. Service call out is not supporting one way call.
Please suggest a suitable way to do this.

Use publish action. It is designed fire and forget type of use-cases

How to return "HTTP/1.0 401 Authorization Required" from OSB's Message Flow

How can I return "HTTP/1.0 401 Authorization Required" header from OSB's Message Flow?
Using of "HTTP Transport -> Authentification" is not possible, because I need flow condition. Transports Headers activity from design palette doesn't allow to send such headers.
Practical usage: request for kerberos ticket by sending two headers: 401 and WWW-Authenticate: Negotiate...

Can you briefly expand the use case for better understanding?
HTTP Client---> Hand Shakes or what ever ----> HTTP Proxy (OSB )---> Pipeline----
Philosophy behind pipeline is that it is designed to work on the request. Correct me if I'm wrong.
What you are asking is ability to control the hand shake either in Pipeline or some way during proxy configuration. Unfortunately there is no configuration that is exposed for HTTP proxies in OSB to control that behavior.

OSB:Publish to business service with for each in osb proxy message flow

Hi,
I have an external application that will make a call to my web-service and post a message to my queue "A" and i need to model my osb component such that it picks the message from that queue " A"and posts it to another queue "B". All this is done without any BPEL involved.
for publishing the message i have created a business service that publishes a msg to the queue A and my proxy service is modelled such that it subscribes to this same queue A and publishes the msg to another business service (that posts it to a queue B).
Everything is working fine but i have an issue in modelling my proxy message flow. If an external application sends a bulk msg i need to post the message one by one to my queue B. I have used for-each and Publish to BS but the msg doesn't get posted one by one. i know i am missing something please help me out.
SOA Suite Version - 11.1.1.3

Are you sure that your for-each definition is correct? Does the flow within the for-each get executed multiple times?
You can check this by logging the variable to which you assign the message in the for-each. Don't forget to put the log level to Error, so you're sure that it's logged.
Let's say you get a list of persons like the following xml in a variable personList
<Persons>
<Person>Glenn</Person>
<Person>Prasanth</Person>
</Persons>
Your for-each definition should be the following.
For each variable: person
XPath: +./Person+
In Variable: personList
You don't mention the Persons element in the XPath expression since it is the root element of the XML. The root element is represented by . (dot).
In the for-each, the variable person can be used like any other variable.

OSB: How to get stored in sbconsole xml document in message flow

Hi
I created a xml document (say ram.xml) as a XML document utility resource in OSB sbconsole.
I want to refer this in message flow with fn:doc. Unlike xquery i can't assign ram.xml to a variable.
I tried fn:doc("/home/osbuser/user_projects/domains/domain_name/osb/config/core/ram.xml") and fn:doc("file:////home/osbuser/user_projects/domains/domain_name/osb/config/core/ram.xml") it didn't work!
I know if i store this xml as a xquery, it will get assigned to a variable. But i am just curious to see how fn:doc works!
Any light !

The reason for this is to eliminitate each assign action for each of XMLs that I use. Each assign gets converted into a xml bean and thats overhead.
If this fn:doc() works, what i am planning is to use fn:doc() inside my xquery transformations directly, without using assign action to load XML.
Also message flow will become somewhat cleaner.
fn:doc() has to be used in a way that it uses relative path to access xml and not complete path (starting from /home/user_doamains/..) because development and production environment domain names are different. Using relative path, code can migrate without any change across environments.

BPMN message flow between oracle functions

Hello all,
I'm working on a BPMN model with several pools and don't arrive to create message flow between oracle functions (human task, notification, etc.) of different pools. With simple functions creation of message flows works fine, the application asks weather a 'belongs to' or a 'message flow' connection should be created. With oracle function a 'belongs to' connection is created automatically. How can I create a message flow between oracle functions?
Thanks

no not really. They are more or less a help construct to identify the specific connection type between functions placed in different pools. This is ARIS meta-model specific and is not BPMN standard.
In future versions this should be fixed … I hope :-)

Proxy Message Flow

Hello everyone,
I am new to OSB and proxy services. I have some questions:
1. In proxy message flow, what is the difference between Pipeline node and routing node?
2. How to call more than one backend?
Any help is appreciated.
Thanks

In the message flow Pipeline Pair is added to do processing on the request before sending it to an external service or processing of the response which is received from the external service. This processing may include transformations, logging/reporting, validations and enrichment as well which can be done by calling other services using Service Callout.
Route is the node you use to send the request to an external service via a business service or even another Proxy Service within OSB which performs a set of functionality.
Pipeline pair and route both are optional, you can have a service with just pipeline pair and still call one or more backend services using Publish or Service Callout. You can also have a service without pipeline pair and just Route node and still do transformation in the Route node.
The choice is yours to design the service message flow in a logical way.
To answer your second question, there are multiple ways to invoke more than one backend service.
You can use Service Callout and Publish in the Pipelines to call any number of backend services. You can also call multiple backends by using Route action in Route node for one backend and having Service CAllouts in the Request actions section of Route action. You can also use Split Join if you want to call multiple backend services in parallel.
Again, it is upto you to design the message flow in a logical way.
For example, for a use case of creating an order in a backend system for a customer, Lets say you have to call a service A to get some customer data based on customer id and then send customer data to another backend service B to create order for that customer. Then ideally you should have a service callout in Request pipeline to Service A, as this is enrichment and then use a Route to call the backend service B to create the Order with enriched customer data.

Xslt in message flow

hello,
i have an XSLT document and i want to use it to make a transformation in the response message flow of my proxy service.
i call a webservice through business service but i dont know which action,in the "response actions", corresponds to making an XSL transformation.
I tried "replace" without success, the others actions seem not to be for transformation.
in the xquery expression editor, i put my XSLT resource to execute.
in "2. bind input", i dont know exactly what to put, there isn't any explication for "2. bind input" in the edocs.
and for "3. bind variables", i have nothing (no variables have been found)
could someone indicate me how to configure and use the result of my xslt in a message flow ?
thank you very much.

We built a custom service and invoked it asynchronously (non-blocking) using the Publish Action (with QoS as BestEffort) in the different places wherever we needed the audit functionality.
And this service would do its work on the background as a part of a separate thread, thereby not impacting the actual service that was implementing the business logic.
This is not optimal because there is still some time consumed for the publish action (though it is less) in the actual service with the business logic. But atleast this did allow us to overcome the limitation of the handlers to some extent.
I generally do not prefer to use java callouts as the prerequisite is that the methods exposed need to be static, which might create some contention when many threads try to invoke the same java callout methods at the same time.
Thanks,
Patrick

Understanding message flow in XI

Hi,
In Understanding message flow in XI /people/siva.maranani/blog/2005/05/25/understanding-message-flow-in-xi
1. What is API and SPI.
2. In return diagram What is the functionality of "servlet"

Hello Anil,
<b>An application programming interface (API)</b> is a source code interface that a computer system or program library provides to support requests for services to be made of it by a computer program. An API differs from an application binary interface in that it is specified in terms of a programming language that can be compiled when an application is built, rather than an explicit low level description of how data is laid out in memory.
The software that provides the functionality described by an API is said to be an implementation of the API. The API itself is abstract, in that it specifies an interface and does not get involved with implementation details.
Two well known APIs are the Single UNIX Specification and the Microsoft Windows API.
An API is often a part of a software development kit (SDK).
The term API is used in two related senses:
A coherent interface consisting of several classes or several sets of related functions or procedures.
A single entry point such as a method, function or procedure.
<b>SPI : Security Parameters Index</b>
