Hi,

am new to MQ Workflow, and am trying to communicate XML messages with the engine.

I have established the communication and MQ Workflow receives my requests and they are handled by the engine. However, I have an issue getting the response when the process completes.

I am using <ProcessTemplateExecute> message, but there is no response written to the ReplyToQueue. When I change the XML message to use <ProcessCreateAndStartInstance> I get a response message indicating that the process has started.

What could be causing the Workflow engine not to return a response when I use <ProcessTemplateExecute> ? Are there any MQ Workflow log files that I can check?

thnx

hos

Hi,

the ProcessExecute API is only suited for short running processes without human interaction because it starts the process and then waits until the whole process has been executed. Usually you have defined all activities to run automatically and all required PEAs and UPESs are started.

You can login with a client program and check where your process instance is stuck. You can also configure audit trail (a good idea in production anyway) and check the audit trail records. There is also a further product WBI Monitor that lets you monitor your environment.

In case of errors you can check MQWFs system.log and error.log e.g. via fmcautil.exe.

A study of the Programming Guide is also recommended if you are coding API programs

<ProcessTemplateExecute> returns the response after the process completed execution. <ProcessTemplateCreateAndStartInstance> returns the response after the process Starts.
