I have one design quetion. I am getting a copy book which either needs to be transformed into XML or send as it is
to Legacy system.Basically there are two diffrent receiving applications one accepts an XML message and another one
accepts a cobol copy book message.
In message flow I need to extract few fields from incoming message(copy book message) and pass it to a servivce which is
HTTP enabled from message flow. This HTTP Service provides certain information which is used for routing determination.

Basically I am planning to use Aggregate nodes and Hppt request node to achive this. We are using WMB 6.0. But in
past during 2.1 I had bad experience with Aggreagate nodes.

Is there any way I can get rid of Aggreagte nodes. If possible please provide me the best design approach for this.

In V6 the design has changed and the aggregate nodes go against a queue instead of a DB. This speeds the process up quite a bit.
Check it out and report if you have problems.

Enjoy

But you don't need Aggregate* nodes with HTTP Requests. They are synchronous.

So you can just do MQInput->Compute->HttpRequest->Compute->MQOutput, for example.

jefflowrey,

I also thought so that we can eliminate Aggregate Nodes

Here is what is comes to my mind

MQInput->Compute1->HttpRequest->Filter->Compute2
| -->MQO/P
->Compute3

Where
Compute1: Will extract relevent information from copybook and prepare
soap message for HttpRequest.

Filter node: will use information provided by service to rout either to Copute2 where copy book message will be tranformed to XML or to compute3 where no change is mde to incoming cobol copy book and send to legacy suytem as it is.

My concern is whether cobol copy book message will remain intact after HttpRequest node. So that either it can be tranformed to xml or send as it is to legacy system.

You can copy the copybook data into Environment.
