I have a Msg FLow that uses Aggregation to fan-out a single message to 2 servers. The replies are returned in BLOB format. Does anyone have any recommendations how to design the reply fan-in message flow. Somehow I need to parse both the message folders that contain BLOB data and extract certain fields for the final output message.

One idea I had was to create a MessageSet that contained all the fields (for both Replies) and use RCD to convert the BLOB to MRM and extract data from there.

Anyone got a better suggestion or like this idea?

I agree with you in creating a message sets which will contain the messages for your replies.

Let´s see your fan-in message flow. Why do you want to use the RCD? I think a better solution is to have two different input queues in the fan-in message flow. Each MQInput node could be configure to parse the BLOB message to MRM. To do this you should configure the MQOutput node in the fan-out message flow to use different reply queues.

I hope this help you. If you have any problem with the scenario just tell us your issues.

Cheers,

Both my replies contain a mixture of formats (a header always in C/COBOL format and a data portion that can be XML or C/COBOL). The way I've been handling this is to parse originally as BLOB, extract the portion of data I care about and then parse it with by using the RCD to reset it to my MRM message set.
