Hi Friends,
Is my below understanding of End-End relation correct, if not, Please advise?
-->1 CM has only 1 Broker Domain.
-->1 Broker Domain can have MULTIPLE Brokers.
-->1 Broker can have MULTIPLE Queue Managers.
-->Each combination of Broker-QM can have MULTIPLE Execution Groups. eg. If Broker1 has 2 QMs (QM1,QM2) then Broker1-QM1 can have multiple Execution Groups (EG1,EG2) and Broker1-QM2 can have multiple Execution Groups (EG3,EG4)
-->And Finally, Each Execution Groups can have multiple Message flows AND multiple instances of same message flows(if configured to support multithreading)
Thanks,
Abhy

First of all, your understanding is a little bit outdated, because from version 7 on there is no CM any more.
Secondly, a broker runs on only one queue manager.

So, lets replace CM by Proxy API.
Also Can't we create multiple QMs under a single broker ?

Let's not, because Message Broker API is not actually a runtime environment.

You create Message Broker on top of a queue manager, not the other way around.
Of course a Message Broker can communicate with several queue managers, but the messages are routed by the underlying broker queue manager. |

So According to this, Should I consider below as Final Correct relation ?
-->1 Broker Domain can have MULTIPLE Brokers.
-->1 Broker can have Only 1 Queue Manager.
-->Each Broker / QM combination can have MULTIPLE Execution Groups. eg. Broker1-QM1 can have multiple Execution Groups (EG1,EG2) and
Broker2-QM2 can have multiple Execution Groups (EG3,EG4)
-->And Finally, Each Execution Groups can have multiple Message flows AND multiple instances of same message flows(if configured to support multithreading).
Thanks.

That's closer.
Except that the concept of a broker domain does not technically exist any more. But of course you are free to call a group of brokers a domain if you like. |
