Passed MuleSoft Certified Developer – Level 1 Exam.

Tried to learn MuleSoft couple of years back around 2017, but gave up because of work schedule and Mule 3 has not excited me that much.

Now with Mule 4, things got changed and tempted me to give it a shot.  Not at all disappointed now.  There is a vast difference between Mule 3 and Mule 4.

End of May 2020, attended instructor-led training course conducted by MuleSoft and thanks to current employer to nominate me for those session.  Failed on first attempt on July first week.  But right after exam, spend an hour to recollect from memory about most of the question and scenario it depicted.  Transcript provides better understanding of your knowledge and let you decide which topics you have to improve.

To pass MCD Level 1 exam, you need to know every minute details about each shape in Mule Pallet and its function.  You have to keep on experimenting each shape and practice a lot.

Retook the exam after 10 days of first attempt and passed it.

 

After long time!!!

Posting here after a long time.  Quite busy with professional and personal part of life.  Though worked extensively on BizTalk 2013 R2 and BizTalk 2016 R2, I cannot able to post those experience and lessons learnt, because of proprietary rights.  Interesting news,  started learning MuleSoft and it is a mixed experience to work with another Integration Tool after BizTalk.  Journey Continues and let see what I am going to learn from it.

Expose Orchestration as WCF Service – Errors – Resolutions

Error 1 :

Receive location for address “/ExposeOrchWCFService/ExposeOrchWCFService_ProcessPO_prtRcvPO.svc” not found. (The BizTalk receive location may be disabled.)

Resolution:

WCF Service Publishing Wizard will create a new Receive location in the application you have specified in the wizard. That receive location need to be enabled.

Error 2:

Cannot open database “BizTalkMgmtDb” requested by the login. The login failed.
Login failed for user ‘NT AUTHORITY\NETWORK SERVICE’.

Resolution:

This happens when you create Orchestration and expose as WCF Service. The WCF Publishing Wizard will create Website in IIS. If newly created application is running under ASP.Net 4.0 Application pool, you will see this error while browsing the .svc file.  All you need to do is to change the Application Pool to WCFHttpAppPool

Error 3:

The requested service, ‘http://localhost/ExposeOrchWCFService/ExposeOrchWCFService_ProcessPO_prtRcvPO.svc’ could not be activated. See the server’s diagnostic trace logs for more information.

Resolution:

Check whether BizTalk Orchestration and application is started.

The Messaging engine failed to process a message submitted by adapter:WCF-BasicHttp

Error Message:

The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on
the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs.

The Messaging engine failed to process a message submitted by adapter:WCF-BasicHttp Source
URL:/ExposeOrchWCFService/ExposeOrchWCFService_ProcessPO_prtRcvPO.svc. Details:The published message could not be routed because no subscribers were found. This error occurs if the subscribing orchestration or send port has not been enlisted, or if some of the message properties necessary for subscription evaluation have not been promoted. Please use the Biztalk Administration console to troubleshoot this failure.

Resolution:

Receive Port ID for the tight coupled orchestration with the Receive port is different that the one which was created by WCF Service publising wizard. You need to change Receive Port configuration to Direct.

Use of unconstructed message ‘messageName’

Compile Error:

use of unconstructed message ‘messageName’

Cause:

If you have 1 message in orchestration, and you are using map to construct message out of same schema then you encounter this error.

Resolution:

Change you logic to use 2 schema or create 2 message variable for the same message.
