BizTalk Aggregration Pattern as a reusable Service!!!

Hello Team,
I'm currently working on SOA pattern and would like to start with having BizTalk Aggregration pattern as a service so that any interface which needs to have batching
process can call this generic aggregation service and in return get the batch msg.
Please refer to the image attached to get better clarity on my requirement.
Any links or suggestions will be useful
Thanks in Advace

Hi Manju,
You have to employ
Canonical Data Model along with aggregation for your requirement.
Create a canonical (detailed internal) schema which would act as single entity containing all the sub-sets data model of the external system. i.e.
you will have an internal schema which contains all the elements/nodes of the inbound schemas. So when you receive schema-A or schema-B, you would map these entire schema to canonical schema (you could do this mapping in port level) and in your BizTalk aggregation,
you will use canonical schema for aggregation. When you send aggregated message out, at the outbound port level you can map the aggregated canonical schema to the outbound specific schema.
This way you can make the BizTalk orchestration/process which aggregates the inbound message as common service since it details with canonical schema,
independent of the source or destination systems.
In the following article you will find reference about the
Canonical Data Model and aggregation pattern.

Several BizTalk applications consuming the same web service

When consuming a web service in Biztalk i use the generated items feature, using the service endpoint address. This creates binding files and service schema files. When trying to deploy the web service artifacts to BizTalk Server, and the files
already is deployed in an other Application, an error is raised. How do I solve the issue? What is best practice? A seperate BizTalk Application hosting the artifacts? Not good I suppose if the enterprise/customer has a limited lisence. A seperate "Proxy"
hosted in a .dll file, developed in e.g. c#? Probably a better solution, but kind of annoying having a lot of those lying around. Any suggestions?
By the way, I'm using BT 2009, if that matters.

John,
Avoid any situations of dynamic schema resolution, such as explicitly setting the document type
in the XmlDisassembler
Could you please explain some pitfalls for this ...i am doing this and wanted to know about it.
Every time when i ran in to schema resolution issue i tend to use dynamic resolution instead of app reference.
Thanks.

SAP JAM work pattern for SAP C4C Service ticket

Can anybody familiar with the SAP JAM Work pattern for SAP Cloud for Customer Service tickets answer these questions?
My client would like to use SAP JAM groups in Service tickets in the following way:
C4C service agents raise service tickets which are then worked on by back-office departments (who don't have access to C4C but will collaborate on ticket resolution via SAP JAM)
Back-office departments work on a high volume of tickets so having one JAM group per ticket is not practical. Instead we would like to have one JAM group per department
Departmental JAM groups should be created in JAM independently from C4C
Upon ticket creation in C4C, the service agent should be able to select the relevant departmental JAM group to collaborate and start a discussion topic
The agent should be able to easily pick up any update/reply from the back office team on the topic he created
Is the scenario above supported? In particular, how can one predefine/auto-select which JAM group is assigned to a service ticket?

BizTalk 2013 R2: SB-Messaging Windows Service Bus On Premise 1.1 (Not Windows Azure)

Let me preface this by saying that I have been able to connect to the destination Service Bus Topics and Queue using traditional .NET methods (e.g. System.ServiceBus.Messaging namespace) and the applications using those components are running fine on the
same local VM. This uses the connection string that is provided from GET-SBAuthorizationRule.
Development Environment:
Windows Server 2012
SQL Server 2014
BizTalk 2013 R2
Local VM that is not on the Domain (but can connect to computers on the network)
I am trying to create a simple BizTalk 2013 R2 Messaging Solution that will use the SB-Messaging adapter features with Windows Service Bus On-Premise. My solution is using a Static One-Way Send Port to send messages to an existing topic on with Windows
Service Bus 1.1 using the SB-Messaging Adapter. After using the programmatic approach, the configurations were not as intuitive, but I believe I am close to the resolution. I have tried several combinations of key data but I am still not able to
connect. This seems like I am missing something small that is causing the problem but I am at a loss for the moment. The error I receive is below:
A message sent to adapter "SB-Messaging" on send port "SBSendPort" with URI "sb://<SERVERNAME>/NsServiceBus/collateraltopic" is suspended.

Below are my Send Port Adapter Configurations:
URI is blacked out
/Namespace/Topic/ are next in the path
Can someone confirm that the Issuer Name is the Namespace and the Issuer Key is the Primary Key from the get-SBAuthorizationRule? I also tried Shared Access Signature (SAS) but that service was connecting to a default port and do not believe that is
how I need to connect.
Also, there is nothing on the Properties Tab as I do not have anything custom for the initial step.
Any and all help is appreciated.

Glenn,
Thank you very much for the response, I will go down this route in further detail. A couple of quick questions for you to help further my understanding.
Where is the SAS limitation documented? I am sure I glossed over it and it did not register, but your help in where to look next time will be helpful.
Also, can I change the default Port for which it is listening on the BizTalk Server or the Service Bus Location? The connection string I get from get-SBAuthorization Rule is as follows:
Endpoint=sb://{ServiceBusLocation}/NsServiceBus;StsEndpoint=https://{ServiceBusLocation}:7355/NsServiceBus;RuntimePort=7354;ManagementPort=7355;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey={KeyValue}
The exception I get is:
A message sent to adapter "SB-Messaging" on send port "SBSendPort" with URI "sb://<ServiceBusLocation>/NsServiceBus/collateraltopic" is suspended.
Error details: System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://<ServiceBusLocation>:9354/. The connection attempt lasted for a time span of 00:00:04.0250873. TCP error code 10061: No connection could be made because the target machine actively refused it <IPAddress>:9354. ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it
at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult)
at System.ServiceModel.Channels.SocketConnectionInitiator.ConnectAsyncResult.OnConnect(IAsyncResult result)
--- End of inner exception stack trace ---
It looks like it is going to 9354 for the authentication when the Service Bus is configured for
7355. I believe I have opened the ports on both ends but do not think it will matter since it looks like it is sending the
request to a different location.
Thank you

Biztalk send to WCF-service that is behind a NLB

A while ago a WCF-service that biztalk 2006 r2 sends to was put behind a NLB.
I find that since than I sometimes get timeouts although biztalk was able to reach the service.
Also in my new test-environment using Bts2013 r2 I find that I sometimes get following response back (although the request was handled ok by the service)
I've been told that this is caused by the load-balancer...any ideas on how to solve this/what could be causing this

Getting Server Error Code: -2147024891 when using Biztalk Windows SharePoint Services Adapter to upload a document

We are currently running
1. BizTalk Server 2013 R2
2. SharePoint 2013
both in a Windows 2012 Server environment, in Azure.   The BizTalk and SharePoint are running on separate machines.
I am using the Windows SharePoint Adapter to upload a Tif file to a SharePoint document library. However, when the host instance is running under my team member's userid, I get the following error in the eventlog:
The adapter failed to transmit message going to send port "SendOwnershipToSharePoint" with URL "wss://bp1amsapt218:34392/sites/BiztalkSc/Lists/Ownership". It will be retransmitted after the retry interval specified for this Send Port.

I have also made sure the userid has full control access to the SharePoint site and the document library within the site.   I have confirmed that the user with this userid is able to access the SharePoint site and can upload documents to the
document library, manually.   However, when the host instance is running under this userid, I am not able to upload documents to the SharePoint document library.
The Windows SharePoint Services Adapter is configured with the following values:

Do you know what the cause for this error is?   We urgently need a resolution for this?

If you create an XML document and upload it to the Windows SharePoint Services Web site. The Windows SharePoint Services adapter will take that message, archive it in the Archive document library, and then send it to the Destination document library. This
procedure demonstrates how a document flows from a Sharepoint web site, through BizTalk Server, and to a Sharepoint Services Web site using the Windows Sharepoint Services adapter.
This MSDN library article shows the procedure, please check whether it will be helpful to troubleshoot.

Service Locator Pattern

I have a question about the Service Locator Pattern. If The service locator caches the EJBHome references in a Hashmap and retreives them though a method, does that method need to be synchronized for Thread Safety?
If it has to be synchronized, doesnt it introduce performance bottle neck by letting only 1 thread access the method at any time?
Please see code snippet below...
Thanks,
Krish
public static synchronized EJBHome getHome(Class homeClass) throws NamingExeption {
EJBHome home = (EJBHome) this.homes.get(homeClass);
if(home == null) {
ctx = getInitialContext();
home = (EJBHome) PortableRemoteObject.narrow(ctx.lookup(homeClass.getName()),homeClass);
this.homes.put(homeClass,home);
return home;
}

Answer an interesting question?
Create a wiki article about it!

Error Handling in BizTalk

My Scenario is - I will be receiving Batched files (FlatFile) and my BizTalk will be interacting with Web services(WCF)
My suggestions was to use ESB but I was told for Batched messages ESB is not a good idea. It works good for debatched messages.
Any suggestions for my scenario please ?
MBH

Now that's a different scenario. Instead of starting with how to handle exceptions, focus on avoiding them in first place.
With 10k batches, you should consider a Resource Dispenser or Thottling pattern since as a caller, BizTalk can easily overwhelm your average internal service endpoint.
How to handle exceptions depends on what the business expectation is and who must handle them.

Consuming REST services

Hi,
Can you please let me know the approach to consume a REST service dynamically.
I have a custom orchestration service as described in the below thread. I use BRE resolvers to resolve and set the endpoints runtime on dynamic ports. Also using dynamic transforms.
http://www.ithero.nl/post/2013/06/02/Creating-a-Custom-Itinerary-Orchestration-Service-for-the-Recipient-List-pattern.aspx
Now i want to extend this to invoke REST apis as well. Can you please guide to a link or share some ideas on how this can be achieved using BizTalk 2013.
Also could you please comment on authentication of such requests.
Thanks,
Ujjwal

Re: Service Object events and LockMgr

On the option that you have considered, I have implemented the same model
in my previous project (using Java/RMI), but I felt that it is more than
what is normally needed for concurrency protection.
I can suggest another option that is worth considering which is in place in
our app for concurrency.
Almost every table in our db has created By, created On, modifed By,
modified On columns. The parent class of all business objects has
attributes that correspond to these four columns. In addition to these
four, there is a fifth attribute (introduced when concurrency was built)
called originalModifiedOn. Upon retrieval from the db, it is set to
modifiedOn value (from the db), during UPDATE, the value in this column is
added part of the WHERE clause. So when the second user tried to do save
the same object, the underlying db update will get a 'zero rows updated'
which is translated into an application error 'possible concurrency
error'. The user re-retreives the now 'stale' object before applying their
edits.
A lot of these things are and can be built into the framework imposing very
little work that each Object needs to do to have concurrency protection.
I am not sure if there is a mention in the Patterns paper of this model,
but it is very easy to implement and supports what is needed.

Subject: Service Object events and LockMgr
Hi folks,
We're currently looking at strategies for dealing with the simultaneous
updates to the database from multiple clients (concurrency
management). That is when two (or more) clients load the same object to
edit it, then make different changes and save them to the database.
We have a copy of a Forté document (from the "Patterns" course, I
think) which describes three methods of dealing with this:
1) Lock the database table row as soon as a client select it for editing
and hold the lock until it is saved.
2) Immediately before 'saving' check that the database hasn't changed
(either by reading what's there before updating, or by using a huge
'where' clause that contains all unchanged fields)
3) The Forté "LockMgr" pattern, which uses a service object with notifier
proxies to allow locking and updating notification between the clients.
Option 3 is obviously the most robust method, but it requires a fair
amount of coding and could also be a bottleneck for database reads and
writes.
But I have another option for which I was looking for opinions. What if
we had a "Change Event manager" which broadcast an event every time
a change is made to the database. Each business class would have its
own event. If the event had the object's primary key as a parameter, then
clients editing that particular object type could check to see if the object
currently on screen is the one that changed. That way you could disable
the 'save' until they had refreshed their on-screen data.
It's not particularily elegant, but it's reasonably simple to implement. It
also deals with changes sent across our WAN from other database
servers.
But this option is only worthwhile if you can replicate the "Change Event
manager" SO and still register for an event on the client. Can clients
register for SO events and receive an event generated by any of the SO's
replicates? Or when you register for an SO's event do you register for
only one instance of the SO?
Thanks in advance for any answers.

Hi,
Just wonder exactly how this Lock Manager can be implemented. Do you mean that you are
going to cache every object that is instantiated from the database? Or you just cache
the object id, primary key, etc?
Frankly speaking, I won't attempt to due with this kind of currency coding myself as
the database vendor has spent years in coding just to do this.
Regards.

I would recommend you to use the following approach (of course if you
do not have some special requirements :) ):
1. You should have a LockManager that will synchronize all clients in
their attempt to modify/delete objects in your application.
2. Each client, when attempts to modify/delete some object, it must
LOCK it using the services provided with the LockManager.
3. The requested operation can be performed only after successful
locking.
4. If a lock can not be obtained (for example if the object is already
locked by some other client) then the operation is aborted.
The details of this pattern depends on your needs. :)
Hope this helps.

How to call Biztalk through ABAP-DYNPRO

Hi All ,
I want to call a function module which in BIZTALK Server through
ABAP-DYNPRO ( by service call) . for this I require Destination details ( in service call ) .
Can anyone please send me the Destination details or the approach to follow for calling the Biztalk ?
Thanks in advance ..
Regards
Rahul

Run a search on Web service calls from WDA.
This topic has been addressed on numerous occassions.
You can call BIZ-TALK using a web service.
You could also call it using straight HTTP .
There are classes in ABAP to allow you to write an HTTP client app if required.
If possible go the Webservice route.
IE have you Biztalk guy generate a WSDL for the call.
The follow instructions on numerous threads on calling web services.
Cheers
Phil.

Web service scenario - Missing or Invalid Receiver Agreement

Dear,
We are on SAP PI 7.11 SP11 and facing a problem with a synchronous scenario SOAP <-> SAP PI <-> ABAP proxy.
The Service Interfaces contain multiple operations and operation/message mappings are in place.
Also, configuration on the ID side is done.
The WSDL is retrieved from the sender agreement and imported into soapUI.
All seems there and the cache is ok, but still we face the error Missing or Invalid Receiver Agreement in the message monitor.
I already found OSS note 1739173, describing the problem, but that seems to be for asynchronous messages only with QoS EO and EOIO.
Or do we need that anyway?
Any leads what could solve this strange problem?
thanks a lot.
Dimitri

Hi,
Both outbound and inbound service interface have multiple operations.
The configuration:
ESR
Outbound and inbound service interfaces containing 5 operations each.
All synchronous, interface pattern stateless.
Outbound service interface is linked to an external message.
The Inbound service interface is linked to a message type.
For every operation, a operation mapping and message mapping is available.
Integration Directory
seperate configuration objects. No ICO is used.
Sender Agreement
no validation
Software Component Version of Sender Interface is pointing to the SWCV, containing the outbound service interface
sender SOAP communication channel
HTTP
SOAP 1.1
Do not use SOAP envelope enabled
QoS is best effort
Receiver Determination
software component version left blank. So, no operation-specifics mentioned.
type of receiver determination is standard
receiver is the SAP back end system (business system)
Interface Determination
Software Component Version of Sender Interface is pointing to the SWCV, containing the outbound service interface
for each operation, a operation mapping, inbound service interface and namespace is indicated
Receiver Agreement
receiver XI adapter
HTTP 1.0
XI 3.0
HTTP destination to the SAP back end
Transfer hop list enabled
Software Component Version of receiver Interface is pointing to the SWCV, containing the inbound service interface
Please note
the message mapping is a XSLT mapping
tests with single-operation service interfaces are successful.
Kind regards,
Dimitri

Exception Handling in BizTalk

what is the best way to handle errors in BizTalk ?
We are using web services, databases.
Is ESB Exception handling preferred to others ? any better suggestions please ?
MBH

You don't need custom-Itineraries /On Ramp/Off Ramp for repaid and resubmit using ESB portal. But you need to have receive ports, send ports, orchestration which comes with ESB tool kit for this purpose. When a failure is published to ESB-bus,
"catch all” exception send port will pick it up and publish it to the ESB Exceptiondb. Then using the ESB portal you can edit/repair the message and resubmit it directly from the portal without using the ESB-Toolkit artefacts like Itineraries /On Ramp/Off
Ramp.
Refer this article where author uses this feature without any custom ESB-toolkit artefacts
http://seroter.wordpress.com/2010/01/18/considerations-when-retrying-failed-messages-in-biztalk-or-the-esb-toolkit/
One option to route a failed message to the ESB Portal one must turn on routing for failed messages on the send port. This results in the failed message being routed to the ESB Exception database along with the exception details. Even in orchestration's
you can submit the failed message to ESBException DB from where you can repair and resubmit the message.
Refer this article for more help on this context:
