Sam,
In general you should learn:
1. How to create message flow and use different nodes to implement a message flow.
2. Get familiar with MQSeries also.
3. How to setup simple broker domain.
4. How to debug message Flows.
5. How to model different types of message flows and how to handle them.
6. Request/Reply scenario.
7. Aggregation.
For pub/sub, start with SupportPac, MA0D - Getting started with MQSeries Publish/Subscribe. Once you understand the basic concept of pub/sub, you can then move on to MQSI (Publication…etc).

For a request/reply scenario, is it better to develop both the request/reply flows in the same message flow, or is it better to develop them in two different message flows (one for request, one for reply)?

I would prefer to have two different message flows for Request and Reply.

Thanks. But I have another question 
I currently have a message flow which is getting messages from a number of different queues, all of these messages sharing the same message format. All of these messages will go through the same compute nodes and stuffs and will end up in the same output node (output queues are defined dynamically using the 'destinationlist' method).
Since I'm getting the messages from more than one queue, I have to define more than one input node. Question is, should I define 2 input nodes (assuming I have 2 input queues) in one message flow, or should I define 2 message flows (one message flow for each input queue)?
Which method will offer the better performance in overall? Thanks again.

Hi Kiran,
Thanks, for ur suggestions.... infact i have worked already from step 1 to step 5, but i have one more question please. when i try to convert mrm to xml i'm getting my xml message correctly, but i'm not getting the values.. Why??? my input is <MRM><MRM1><FNAME>aaaaa</FNAME><MNAME>BBBBB</MNAME><LNAME>CCCCC</LNAME><MRM1><MRM> and my output is <XML1><FIRSTNAME></FIRSTNAME><MIDDLENAME></MIDDLENAME><LASTNAME></LASTNAME></XML1>
my esql is
SET "OutputRoot"."XML"."XML1"."FIRSTNAME" = "InputBody"."MRM1"."FNAME";
SET "OutputRoot"."XML"."XML1"."MIDDLENAME" = "InputBody"."MRM1"."MNAME";
SET "OutputRoot"."XML"."XML1"."LASTNAME" = "InputBody"."MRM1"."LNAME";
SET OutputRoot.Properties.MessageSet = 'DQ86UM407U001';
SET OutputRoot.Properties.MessageType = 'XML_MSG';
SET OutputRoot.Properties.MessageDomain = 'XML';
SET OutputRoot.Properties.MessageFormat = 'CWF';
please, help |

Hi Sam,
Are you converting from MRM-CWF to Generic XML or something else? Looking at your input/output message and ESQL code, I think you are trying to convert from MRM-XML to Generic XML? Is this is what you want to do?

Well .. in that case, you have to configure your MQInput node to specify Message domain to MRM, MessageSet to 'D....', MessageType to 'xxxx' and MessageFormat to 'CWF'. Before this, you have to create message set, which has Following Elements,
FNAME - Length 5
MNAME - Length 5
LNAME - Length 5
Create a MRM message, which contains these elements and assign it to the broker.
In your message flow, your Compute node ESQL could be:
SET OutputRoot.XML.XML1.FIRSTNAME = InputBody.FNAME;
SET OutputRoot.XML.XML1.MIDDLENAME = InputBody.MNAME;
SET OutputRoot.XML.XML1.LASTNAME = InputBody.LNAME;
Hope this gives you some lead.

yes, kiran i did the same thing my mrm looks like this
MRM1 is the root and it contains three elements FNAME, MNAME, LNAME and all three elements has value = 5. and i configured my inupt node as u said ie. domain = mrm;set = D..; type = xxx; format = cwf;
my xml msg set look like these
XML1 is the root and it containes three elements FIRSTNAME, MIDDLENAME, LASTNAME and all three elements has value = 5
once again thanks for ur reponse |

Your input msg should look like this...
aaaaabbbbbccccc
... If you're trying to place an mrm-cwf msg into the input node. And make sure you check 'copy message headers only' in your compute node. Then it should work fine.

Are you sure you've created your message set properly? Let's recap...
In order for your input message to be 'received' properly by WMQI, (aaaaabbbbbccccc), you need to create a message set. Add a CWF layer format to this message set. Then, you need to create a message. While creating the message (I recommend using the SmartGuide), you create the elements.
Also, make sure you assign BOTH the message set AND the message flow in the assignments tab. The message set into the broker, and the message flow into the execution group. Deploy...
If error still occurs, use the debugger that is provided in WMQI.

Do you need to specify the outer tag name in your set statements?
SET "OutputRoot"."XML"."XML1"."FIRSTNAME" = "InputBody"."MRM".MRM1"."FNAME";
SET "OutputRoot"."XML"."XML1"."MIDDLENAME" = "InputBody"."MRM"."MRM1"."MNAME";
SET "OutputRoot"."XML"."XML1"."LASTNAME" = "InputBody"."MRM"."MRM1"."LNAME";
Also, on your input message I am guessing you have a typo?? MRM and MRM1 don't have the / for the end tag.
