my main question is
as the messages to Cluster qmgr MQ4A are comming from MQ3 , if MQ4A fails then MQ 4b can't take the messages as they are commimg from outside the cluster (Mq 3 puts messages to Qlocal in MQ 4A) so High availability is not achieved nor even the load balanching
can anyone suggest the best way plzz |
1) WMQ clustering should not be used to provide high availability for (at least) the reason you give above. Use HACMP, VCS, or this Heatbeat thing, or something. As you were told here.
2) If both MQ4A & MQ4B are in the same cluster and running then of course you can achieve load balancing as outlined in the Cluster manual. It only doesn't load balance because you're pointing directly at MQ4A.

"Heart beat," and "clustering" are valid MQ technical terms. Heartbeats are used in WMQ channels, and MI qmgr clusters. |
Quotes are changing the meaning of the whole term(s). And here you did that.

60 characters for a subject line is not less at all.
OP's effort is appreciated (but its not his/her the best).

I'd like to suggest that the off-topic stuff about how to write a question on this forum moves out to a separate thread.
Mitra, speaking for myself only (though it seems I am not alone), I had not heard of using MQ in the environment you are talking about.
I had hoped someone would jump in and say "yes I use it", or something like that. But it doesn't look like that's going to happen.
Just in case it helps, this page http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/topic/com.ibm.mq.amqzag.doc/fa70230_.htm gives details of how to set up HACMP and similar environments to use MQ. |

Again, you are nit-picking.
The purpose of this site is NOT to criticize the OP's efforts, and NOT to criticize grammar AND punctuation. The OP is new to this site. Give him/her a break.
Do you believe that telling him/her that the original subject line was wrong will encourage better posts in the future? Or, do you believe that such criticism will intimidate? Apparently, you don't enjoy being criticized; and you confirm this by nit-picking.
Yes, you are technically correct that Its wrong, because there is no term 'Heart Beat Clustering' in MQ..
One of the more common complaints about technical people is that they give abrupt, technically correct,answers that tend to make the the recipient feel more stupid than before they asked the question.
Be professional here. Offer specifics. Offer several examples of how the subject line might have been improved. Take a risk. Get some skin in the game.
In short, merely telling someone they are wrong, gives them no useful information with which to improve.

There may well be heartbeats between resources in a hardware cluster but I've never heard of a 'heartbeat cluster'... |
If you clicked through on the link provided, you would see that some enterprising person has decided that 'heartbeat' is just the *perfect* name for a piece of open source HA software. |
Bloody typical! Google didn't find that on page 1 and I was too busy (lazy?) to click the link...

I would say, the subject line from OP is wrong !

By 'wrong,' did you mean that the subject line is inconsistent with the end-result of the post Q&A?
I can certainly live with 'inconsistent.'
