Hi All,
MQ5.3 CSD5 (NT/2000)
Hub (central ) and spoke are in MQCluster.
We have a scenario, where our client should put the message to primary(spoke) or secondary (spoke)QM only if, the hub (central) QMGR is available.
Can you suggest me an option (MQPUT message option) in MQ so that when my client putting the message into primary and if the Hub QMGR (central QMGR) is unavailable/network issue/channel issue.
It should prevent me putting the messages to the "image of the cluster queue" and return the error to client, so that my client can connect through another QMGR (secondary spoke) and try to put the message through the secondary QMGR (spoke).
I know that is there is such issues I will get 2188 error, but the issues is I get say after 2 or 3 messages getting struck in the transmission queue.
My concerns are I should get the return code as soon as there is network issues between the spoke and hub QMGR/channel issues/if the hub QMGR is down.
I don’t want any of my messages getting struck in transmission queue due to such issues.
Please suggest/comment |

No. Don't do this.
It's a really really bad idea.
If the requirement is really to make systems this tightly coupled, then you should not use WebSphere MQ. You should use some other synchronous transport, instead of an asychronous transport.
