Hi, can some one tell me what is a Queue Manager Gateway.. and how do i use it.
I have a situation here, where i need to cluster two or more Queue manager, and provide a Queue manager Gateway and client send message to gate way.. i saw a post ans was too high level for me to proceed.
so, please help me with some tutorial site for Queue manager Gateway of MQ 6.0.0.0
and clustering the same with an example of Consumer and Producer.
amqsget and amqput is also good for consumer and producer examples.
Thanks,
tumstech |

a very crude example would be
have a cluster of 3 queue managers
create instances of local clustered queue on 2 queue managers and use third queue manager to post message on these queues
hence your third queue manager would act as a gateway
General we talk of QM gateway while using overlapping clusters..
Refer to MQ clustering manual for complete detailed information...

Of course this use of "gateway" became obsolete with the introduction of the CLWLUSEQ attribute in v6, which the poster is using.

I believe this is what the poster is getting at.

There are also a number of good posts in here, not only on how to overlap clusters but when it is (and isn't) a good idea.

You can also have a look at the scenarios when a queue manager 'A' is outside the cluster 'CLUSTER1' and rest of the queue managers are inside the cluster say 'B', 'C'. And application is connected to 'A' (gateway qmgr) and trying to put the message on cluster qmgrs.
Manuals are there in IBM Site OR at the link at the TOP of this forum.
And I am agree with Vitor's comment too on this.

If Queue Manager A is outside of the cluster then it is not a Gateway QM.

I am sorry, I can stand with it AND with the statements/posts which were given in the link below. Pls have a look at http://www.mqseries.net/phpBB2/viewtopic.php?p=243585&highlight=#243585
On its Page no. 2 ., where a discussion on 'Gateway' was done. Its been a long time since then.
