Ok let's have some fun... I am in the mood
and it will be my 1600th post...




Generates for QMGRA:
Code:

ALTER  QMGR +
       REPOS('CLUSTERA')

DEFINE QLOCAL('QUEUEA') +

Spiffy!

While I understand your reasons for not following the design standards laid out in MD08, it would still be nice to see a cluster as a container of qmgrs, rather than a link between qmgrs, maybe with links from the container to the FR.

On the other hand, I can now think of a several reasons why it's a bad idea to make it like that... hrm.

Thanks, there has been a lot of blood sweat and tears in this simple picture, it's been a fascinating journey and it's just the begining...

there are always pro's and con's to any way you want to picture it, this is the way you would 'draw' it on a whiteboard and allows for regular MQ channels to be part of the picture aswell.
everyday I get more and more ideas, but so little time... next months I'll be writing articles and preparing flash demo's as this really looks cool when 'alive' ...

more will follow in the next months

Thank you guys I appreciate your ideas...,

lets say I have couple of system like 3-to-5 systems(servers) in distributed env. have many qmanager and quesues(local, remote) defined and even some qnames use the same name(but different system or server). I wanna convert them into cluster.
whay path you think is better to follow?
If you guys be more spesific I can better understand since I am new in MQ env. I am looking at the links you provided.
Thnks

The answer is it all depends on what you want to use them for...

Changing a queue to be a clustered queue because it's name shows up more than once in the environment is a very poor reason for creating a cluster...

Changing a queue to be a clustered queue because you need load balancing, is a very good reason to create a cluster...

Enjoy

The reason is for easier management, to reduce the number of definitions for like qremote, channels etc... and to get the whole picture easier.

The big thing to watch out for is NEVER EVER EVER EVER EVER have two qmgrs in the same cluster when the two qmgrs have the same name.

It's only about NEVER EVER for merely having two qmgrs with the same name in the same network.

Once you've made sure of that, then clustering is a good choice to reduce the number of channels and transmit queues you need to maintain. And if you happen to want to loadbalance as well, it's a double-win.

If you are after a quick and painless introduction to MQ Clustering - there is a podcast by Andy Banks 'the grand daddy' of clustering here
