Hi,
I need to split an incoming message(based on a delimiter) containing a number of sub-messages and perform various operations on the individual messages.
There after these individual messages need to be grouped in the same order.
Can anyone please suggest an approach for this in WMQI/WMB. Does WMB have any inbuilt functionality?
Thanks & Regards
Janice |

You can do this using one message flow.
TDS parser can help you to split incoming message into sub-messages.
Then in Compute node you can propagate sub-messages one by one.
After this may be ResetContentDescriptor to parse sub-messages and processing routine for one sub-message.
And finally you can use a Compute node that combines your sub-messages in Environment tree or shared variable.
Total count of sub-messages you can store also in a shared variable.
This scheme can be modified to use two message flows. In that case you can use shared variables or external data store (e.g. database table) to combine processed sub-messages.

Hi Janice_Shania,
Use a message set, get the parsed message and loop through using references and make multiple requests.
On the return, use MQGet or Aggregation(propagate using Aggregate) to group the messages back.
A little more info wil help us understand your reqirement better, but on a higer level of understanding this should be a simple approach.
Regards. |

You can't share variables betweeen different flows. Only between different invocations of the same flow.

Of course.
I mean that you can store some input messages of your flow in a shared variable.
But reliability... 
Aggregate or database should be a better way. |
