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
A message sent to adapter "WCF-Custom" on send port "aa" with URI "https://test.svc" is suspended.
Error details: System.ServiceModel.CommunicationException: An error occurred while receiving the HTTP response to

Custom wcf service that uses SharePoint Object Model.

Hi All,
I am writing a custom service on SharePoint. I have noticed most of the people do deploy the custom wcf service in layout folder in 12/14/15 hive. I am wondering is it mandatory? Can’t we deploy the custom wcf service that uses SharePoint Object Model as
virtual directory on a specific port?
Regards Restless Spirit

It is suggested to use WCF in 12/14/15 hive folder due to security and eas in use. Check below

http://stackoverflow.com/questions/16008593/where-should-custom-wcf-service-for-sharepoint-2010-resides
If you want to use the server object model you have to host your WCF service on the same server as your SharePoint is installed on.
If the WCF service has to be on a different server you can use the client object model or the SharePoint webservices to communicate to SharePoint.

You get this error because your published orchestration (WCF service) is running in an application pool (IIS) which security user is not a member of the BizTalk Isolated Host Users group.
To solve this issue create an application pool with a security user that is part of the BizTalk Isolated Host Users Group or check the current application pool and add the user to the BizTalk Isolated Host Users.

Biztalk: Publish as WCF Service

Hello Experts,
In Biztalk, i want to publish a WCF Service
As i understand it can be done in two way
1. Schemas as a Webservice
2. Orchestration as a webservice
i want a string as input for that webservice, it is just a string
can you please advise how we can publish a webservice which will take string as input.
Thanks for help

A quick way I can think of is,
create an Orchestration, create a message of type "System.String" from .NET classes.
Create a receive port and in Select a Port Type, change
Access Restrictions from Internal (default) to
Public-no limits. This will enable you to expose the Orchestration as WCF service
Create the rest of the orchestration with your business process that you want to do with the received message.
Now publish the Orchestration as WCF service, now this will access only string as the input.

BizTalk published WCF service throwing HTTP 404 error using ISA reverse proxy settings

I have published my schemas as a WCF service from BizTalk 2010 "Publish WCF Service" wizard. I used Wcf-basicHTTP adapter in receive port. I am able to run the service successfully on localhost IIS and I tested my biztalk solution by sending request using SOAP UI and got response successfully.... Now: Actually, I need to give this service endpoint to my vendor who will send request from outside my company's network i.e. internet. In my infrastrucrue BizTalk is behind the firewall so, we setup a REVERSE proxy server at DMZ layer and it is configured properly. I have tested a simple WCF service by replacing the localhost with Proxy server configured address <DNSName> and it worked absolutely fine. But when I change localhost in my BizTalk schema based published WCF service it is not working and I am getting following error. Really strugling to get it resolved. I wasted a whole 3 days....very upset. Please help me out by giving the detailed step solution. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /BizTalkServiceInstance/MyService.svc I am surprized why other c# code based WCF services are working fine with reverse proxy settings. Server Error in '/' Application. The resource cannot be found.Is there any special things to consider Biztalk exposed wcf servcie over ssl in IIS cluster with ISA

Hi Singam :)
First I would start by browsing any other files (files other than the one from WCF) just to ensure that the reverse-proxy’s redirection rules are set correctly. If you get the same 404 error when you try to access other service/files “through reverse-proxy”,
then it’s an issue in the redirection rule(s) in reverse-proxy.
If others are fine i.e. no issue in reverse-proxy setup as such, then try the following for WCF service's web.config file. I have seen this issue in WCF service (not just BizTalk’s artifacts exposed as service in reverse-proxy). Add serviceHostingEnvironment
config as show with in serviceModel section.
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>

How to send EDI from WCF adapter to WCF service

Hi,
1. I have created an orchestration which is published as WCF service.
2. I have created an orchestration which receives an XML from WCF client and process it.
3. I have created a WCF dynamic send port.
Problem: From this dynamic send port, I want to send EDI file to a WCF service that will receive this EDI file. How can I achieve this. Below are my concerns:
-> For creating this WCF service, I need to know the contract of Biztalk WCF adapter which sends EDI file.
Thanks ...

Hi,
How can we create WCF service to receive the EDI sent by the BTS. What contract should be used for receiving this EDI file in WCF service.
What changes have to be made in the orchestrations to send the EDI file to the WCF send Dynamic port. Below is the code i am using.
EDIOutboundPort(Microsoft.XLANGs.BaseTypes.Address)="URL Address";
EDIOutboundPort(Microsoft.XLANGs.BaseTypes.TransportType)="WCF-basicHttp";
Please correct me if i am wrong
Thanks
"How can we create WCF service to receive the EDI sent by the BTS. What contract should be used for receiving this EDI file in WCF service" - This is two different questions.
"How can we create WCF service to receive the EDI sent by the BTS" - Using BizTalk WCF Services Publishing Wizard, the wizard would ask for the "Create BizTalk receive locations in the following application " for creating
the receive location for the message published to the exposed WCF service. Through this receive port/location, the service would receive the message.
In this case, I am not sure why do you want to expose the Orchestration as WCF Service when you want to send message to this Orchestration/WCF service (which after converting from Orch) through another orchestration. You could either use call/start orchestration
to send message from one to another.
"What contract should be used for receiving this EDI file in WCF service" - may be this question is not correct. You have created a Orchestration which you exposed as WCF service. So while creating the Orch you know the type of message this Orchestration
is bound to, so use the same contract. Or as mentioned in my earlier reply, use "Consume WCF wizard" to consume the WCF service which would create the web message for you.

Questions regarding deploying Biztalk WCF service to higher environments.

Here is my situation:
I have published BizTalk schema as WCF service in my local.
I need to move this to higher environments, is there any way I can move this to upper environments without again using WCF service publishing wizard in respective environments.

Hi,
These are the more common options that I have used for this task:
Use the IIS Web Deploy: with this tool, you can export the WCF Service as a ZIP package that can be imported in the target environment manually or using the command line.
http://www.iis.net/downloads/microsoft/web-deploy
http://jpsmit.bloggingabout.net/2012/06/04/deploying-wcf-services-using-web-deploy/
Include the WCF service inside the BizTalk deployment package: I don't recommend this approach because it doesn't allow almost any customization when deployed in the target environment.
Generate a Web Setup Project: other option can be creating a web setup Project in visual studio that will deploy the WCF service.It allows some customization when deploying in the target enviorment.
http://jpsmit.bloggingabout.net/2010/03/29/deploying-a-wcf-service-using-a-web-setup-project/
Using a custom tool: as Rachid Sikrosia said in the previous post, you can use BizTalk Deployment Framework o BizTalk powershell addin to do this task.
https://psbiztalk.codeplex.com/
In my last Project, I have used a combination of both Web Setup Project and some powershell scripts to configure correctly the web site, application pool, enabled bindings, etc...

Provide WCF service caller to a SQL server that is access by a technical user account

Hi,
we have a WCF Service that is hosted in a windows service and access a SQL Server database. The database is accessed with the technical user the windows service runs with. That means nevertheless of the WCF service caller, the database is always
accessed in context of the technical user. Furthermore some company users access the database via the SQL Management Studio and sign in via Windows Authentication.
The management now wants us to provide a change log functionality. In case data is changed by the WCF service the caller should be logged. In case of using the SQL Management Studio the domain-user's account should be logged.
Because both ways must be supported we want to use a table trigge to monitor insert/update/delete ddl events, but we got struggled by passing the WCF service caller to the SQL server database.
Does anyone have a good idea for the issue? Any advice is appreciated.
Kind regards,
Christian

Do you know a way to use the 'SET CONTEXT_INFO' expression wth LINQ2SQL?
This is a T-SQL forum. There are other forms for LINQ.
No, I don't know LINQ. Then again, why on earth would you? This would be a command you would submit when the WCF connects. Ah, of course, you are only connecting when you submit a query. Which you do through LINQ. Oh well. Could be an incitement to move
away from LINQ maybe? :-)

Best Solution for Busy WCF Service to Database

I have a WCF service that writes log records to a database for several applications. It logs sometimes 200K+ an hour. I am using entity framework currently to create the records and each is created independently (per call). That means a connection
is getting created for each one. I've found that because of the heavy amount of connections (this database is shared with another application), that I'm having max connection issues. Since this application is consistently writing to the database, I didn't
know if there was a better way of limiting its connections (maybe sharing them) as the inserts are done asynchronously so the requestor is not held up, and they don't have to be immediately inserted. Since immediately having them isn't a must have, I've also
considered writing the logs to a file then building a batch insert to occur every so often so that only one connection is open when that occurs. Just wondering what may be some suggestions on the best way to go about the creation and handling of the database
connections for a system like this? Thanks.

Hello acfalcon2001,
From my experience, in your case, it is not recommended to call SaveChange() for every record because as you also mentions, it would cause a the heavy amount of connections.
>>I've also considered writing the logs to a file then building a batch insert to occur every so often so that only one connection is open when that occurs
This is the way I would suggest you could do for your case, for using the batch insert in Entity Framework, you could set a static variable to count added the number of entities, if it reaches a limit number(you could set it to 100 or 1000 or others) and
then call the SaveChange() method(this method actually perform a batch insert operation even for one record). For this way, you could refer to the link below to check a detail usage and there is
detail test information:
http://stackoverflow.com/a/5942176
Or you could use another method:EntityFramework.BulkInsert
https://efbulkinsert.codeplex.com/
And from your description, it seems that your service would only perform an insert operation, if so, you could set:
yourContext.Configuration.AutoDetectChangesEnabled = false;
yourContext.Configuration.ValidateOnSaveEnabled = false;
This coudl improve performance of insertion.

SSIS Web Service Task Error with WCF Service

I have read all the other posts on this site and have not been able to resolve my issue.
For testing purposes i created a very simple WCF service that takes no arguments and returns true. That is all it does.
When i create a winform client and instantiate the service i can run my service method and get true back so i know the service works.
I then create a test SSIS package with 1 task, a web service task.
I set the web service tasks properties as follows:
http connection: http://localhost/WCF_SSIS_Prototype/Service1.svc
wsdl file: C:\...\SSIS_WCF_Prototype\Service1.wsdl (I know this is not a valid path, i changed it for posting to forum)
Service: Service1
Method: GetData
Variable: User::BResult
When i run the package i get the following error:
[Web Service Task] Error: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method. The error is: Method 'ProxyNamespace.Service1.GetData' not found..    at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebMethodInvokerProxy.InvokeMethod(DTSWebMethodInfo methodInfo, String serviceName, Object connection)    at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection)    at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()".
I'm not sure why it is saying "Method 'ProxyNamespace.Service1.GetData' not found. It the web service task trying to create a proxy class and naming the proxy class namespace ProxyNamespace?
Any help is greatly appreciated.

How to communicate with different system on different network using WCF service

Hi,
I am using a WCF service that is accessed by different systems on same network. But systems on different networks are not able to access my WCF service. I have enabled tcp port also. But i can not resolve this issue. Please give the solution to the issue.
Regards,
Shanmugam M

Hi Vilas,
How you may communicate with you AIX server may very greatly depending on what is running on your server. Here is a link to another thread where Java calls and AppletView were discussed. It contains a link to the company that makes AppletView, so it may have some good information for you.
Also, if your customer suggested you use AppletView and they developed it, they would probably be your best bet for explaining it to you.
Hope this helps!

How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file?

How can we send only one message to a WCF service at a time? How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file? Can we do it by Host throttling?

Hi Pawan,
You need to use WCF-Custom adapter and add the ServiceThrottlingBehavior service behavior to a WCF-Custom Locations.
ServiceThrottlingBehavior.MaxConcurrentCalls - Gets or sets a value that specifies the maximum number of messages actively processing across a ServiceHost. The MaxConcurrentCalls property specifies the maximum number of messages actively
processing across a ServiceHost object. Each channel can have one pending message that does not count against the value of MaxConcurrentCalls until WCF begins to process it.

BizTalk Tracking Profile Editor not tracking the data and how to implement the Orchestration as wcf service over SSL

Hi Ashwinprabhu,
thank you very much for your answer.
i have one more query, I have orchestration published as wcf service in IIS and internally orchestration calling one more service , it means orchestration sending a request and getting response back from the service.
actually we are implementing the copy of that called service through biztalk orchestration for system automatic and tracking failed messages and n/w failures.
But tracking profiler not tracking the Data.
And we need to develop the http service as https(Over SSL), we implemented in iis using self
signed certificate, it is working just browser for wsdl(in browser), we are not able to test the service in wcf test client, it is giving wsdl error, in wsdl schema reference showing with HTTP only,
please help me how to resolve the issue.
Teegala

First things first, I think it's best to publish only schemas as WCF service for dependency management reasons. That said - WSDL availability is covered in the WCF adapter under the behaviors. If you're using HTTPBasic this may be hard to modify, but using
WCFCustom allows you to add the WSDL behavior and specify that it should be available via HTTPS.
As to the BAM, are you using TPE within the orchestration or at the port level? I'd imagine your TPE tracks the start and end events of your orchestration using the Orchestration Schedule. If you're fairly confident that the TPE is correct and
yet don't see BAM data 1) make sure your SQL Agent is running healthy and all jobs look OK and 2) check the TDDS tables in both the message box and the BAMPrimaryImport databases. These will show you if there has been some sort of sync issue. There's
even a TDDS errors tables - so check that out.

Biztalk schema exposing as WCF service with multiple operations

Hi,
I am working on a design pattern to expose the BizTalk schema as a WCF service and thought of taking expert’s advice. I have a single schema with 30 different nodes and each one is a different message type. For this 30 message types we need to expose WCF
endpoints to customer for consuming from their application.
When I exposed this schema as WCF service, a single receive location got created in BizTalk application and in IIS there is one .svc file. I defined 30 operations for this while exposing the endpoint with wizard.
Currently I came up with the below 2 approaches but I did not like them as there is more redundancy
Create 30 different orchestrations and each orchestration subscribes to Message Box direct binding with message type as filter.
Create a single orchestration that binds to single receive location( this location got created by wizard..) and access the operation/message type in the expression shape. Based on this value create 30 IF conditions for each message type. For this the
single orchestration receive shape should have a message type of xml document and then access the type. Is it possible?
I don’t like the above approaches as it is very difficult to maintain and also difficult to add for any new message type.
Does anyone has good ideas for doing this?
Thanks
JB

"Canonical Schemas" are used where multiple source messages need to be addressed by a SINGLE Operation !!!
Every operation anyway translates to a separate process. Forget that we're dealing with BizTalk for a minute, when you're writing plain we services, you introduce new service contracts (operations) when you deal with different data contracts. To come back,
in BizTalk your data contracts are your schemas. So when you have multiple schemas, each requiring different processing then you need different orchestrations.
Let us for a minute assume you've defined a single service schema (very possible with a service header and a service details where the service data contract could differ). Now you use this schema to expose ONE service endpoint (good till now). In that service
you're suggesting to ADD decisions (something like a switch statement where you'll do 'x' set of activities is the message is of 'x' type and so on... How is this sustainable? Every time you introduce an new operation, you'll have to tear down and redeploy
the new orchestration which will affect all other operations. During the introduction of ONE op you may touch other parts of the orchestration (multiple branches in a parallel shape anyways make the orchestration very unwieldy from a code management/support
standpoint) and introduce errors in existing ops.

BIzTalk schema exposed as wcf service deployment in WIndows server which dont have bizTalk installed

Microsoft.BizTalk.Adapter.Wcf.Runtime.TransportProxySingleton..cctor() +23
So please advise me on this. Am I going in correct way? Is it possible like this or do we need to install BizTalk for BizTAlk wcf services also in that environment?
Thanks in Advance

Hi,
If you wish to deploy BizTalk WCF services onto another server, you can do so but you need to install BizTalk
there. This is needed because some dlls are needed for the BizTalk WCF services such that it can point effieciently to the receive location in another server (where actual BizTalk application is running). Also the BizTalk runtime is needed in the other server
and hence you need to just install BizTalk on the other server.
Now if your other server is in the DMZ, then you might not go with the above option of installing BizTalk
over there. In that case you need to install Microsoft ISA server (Internet Security and Application Server) and configure your DMZ with that. In that case you can host your BizTalk WCF services over there and make it point to the actual receive locations
on your BizTalk server.
