Hi All,
Our implementation of MQ is limited - but we have used a general approach of a single pair of queues (request/reply) that handle multiple message types. Code on the receiving end, processes all messages, then forwards them on to a appropriate transaction/process.
We wanted to use a similar approach to a new OSB/Oracle client, but the client is having difficulties using a single pair of queues with multiple message types, as the schemas are different (the OSB adapter wants a single schema for the messages - it can't handle multiple schemas easily).
Can I reach out for some guidance on the "normal" implementation pattern, would you:
1. Normally use a seperate pair of queues for each different message type - therefore increasing the number of queues to manage.
2. Normally use single pair of queues per destination, and have a handler to forward on different message types depending on content. - Less queues, but a more complex process on the receiving end.
3. Is it horses for courses, so no particular approach.
Thanks for your help!
Darryl  |

It really depends on the capabilities of the recipient.
I have seen recipients that required multiple queues (data + trigger) and messages by message type.
Typically you would get either a scenario where you have 1 queue per message type, or multiple message types by queue....
The separation however would be on an application + destination basis and not on a destination basis alone.
Any mix and match of the 2 models really depends on the capabilities of the receiving system.
Enjoy

Queues are usually application-based, and named accordingly.
Are you saying that you use a single queue for different business-type messages, for example: payroll time-cards and inventory transactions?
