Hi there,
I've read on this article by IBM -> http://www.ibm.com/developerworks/websphere/library/techarticles/0809_kudikala/0809_kudikala.html on WMB best practises.
Under Configuration section, they mentioned "Do not share the same queue manager across components (broker, username server, configuration manager) especially on production environment."
How relevant is this suggestion? What would be the outcome of having one single QM for all components?
Setup-wise I understand I've to create channels to link them. However in terms of AIX, I need to store the database in one of the QM folders. Now due to such suggestion, I do not know which QM folder to place the database.
Please help? |

The outcome would be one QM would support the multiple components.

Now I've never worked on AIX, but I don't understand that requirement at all. Its certainly not true on Linux and z/Linux.

Ya I know its relevant but what is the consequences of using just one QM? Bottleneck perhaps?

Well I just figured from the IC91 documentation that i've to cater filesystems for the QMs and the documentation states the DB to store in one of the QMs for AIX setup. |

A Config Manager going nuts taking lots of CPU is not going to impact your Broker if they are on seperate QMs on seperate servers. Having to recylce the Config Manager and possibly its QM is a lot safer if its on a seprate server. Seperate servers - just do it. Same QM? Start begging for an outage with the business. IF you are lucky enough to have the option of waiting.
IC91 doesn't have you but the Broker stuff inside the QM folder. But it does live on the same shared disk that the QM data lives on/MQHA/YourQM/data.
Whether the Config Manger or UserName Server share the Broker QM or not doesn't impact this - the Broker's DB lives with the Broker's QM on the same shared disk, IF you choose to host the DB on the same cluster group as the Broker and its QM. The Broker's DB2 could live in a seperate cluster group on the same servers or somewhere completely unrealted to the Broker's cluster entirely.
