Well folks i have one web application talking to multiple legacy db's.
that is my web appication can put 5 different types (Types means different data content in XML format) of messages in a queue.
so what is the best practice in industry for this type of appication :
i.e, shud i create 5 different queues for each message or shud i create just one queue for all message... keping in mind that all the queues are connected to only one QM from where the message is then processed according to data in it.
pl. advice,
Ajit |

I would use only one queue for all these message types. I would use some field in MQMD header, like MsgType or ApplIdentityData to indicate what is the format of the XML message.

thanks kiran,
Even i am in favour of using only one queue, but let me put my question in this way.
I have one web application talking to multiple legacy db's(to be specific 5 db's).
that is my web appication can put 5 different types XML message (Types means different data XML format) in a queue.
and the remote QM has 5 different applications which picks up the message using triggering functionality and CICS transactions.
so what is the best practice in industry for this type of appication :
i.e, shud i create 5 different queues for each message for 5 different applications
what if the remote queue becomes full because the destination queue specific application which picks of the message does not work or is down for maintanance. so what i want is the remaining 4 applications shud work independent of each other.
thanks,
Ajit |

Hi,
If each message type invokes a different "business function or business process" then I strongly suggest that you use separate queues.
This allows for a simple design (plus scalable) and the receiving application does not have to search the queue for its message type (because with separate queues you know that only a specific message type will be in a given queue).
later
Roger...
