| Can a ZOS MQSeries 6.0 queue manager join a mid-tier cluster which has repositories on Solaris and AIX? I have read about the Shared Queue facility available with ZOS MQ (which appears to be somewhat of a counterpart to the mid-tier MQ Clustering facility) but I don't know if ZOS MQ queue manager can also join a cluster and advertise its queues to mid-tier queue managers. |

There's no problem with a cluster across z/OS and mid-range, though you tend to find full repositories on the z/OS for availability reasons (though that's a design issue not a technical one).
AFAIK queue sharing can only be performed between z/OS queue managers; I've never tried queue sharing on a clustered z/OS queue. I suspect you'd encounter problems.
"Ordinary" local queues on z/OS act as the same in a cluster as for mid-range.

Be aware that if you have a mixed cluster of v5.3/v6 queue managers the additional clustering parameters introduced by v6 are ineffective on the lower level queue managers.
The Clustering manual explains all this.

I'd think you could share a shared queue in an MQ Cluster without much problem.
But I'm not a zOs person and I haven't done it. Maybe someone else will chime in ...

Nor me - where the situation's potentially arisen both z/OS queue managers have been cluster members without queue sharing.
Interesting to hear from anybody who's tried it ...

I played with clusters and QSGs a while ago with no problems and the MQ manuals do refer to such architectures. A "shared cluster" search of the infocenter comes up with details, including...

Again, the value of RTFM
Thanks for the links.

z/OS MQ Queue Sharing is done in a fiberoptic attached, high-bandwidth, coupling-facility storage device. Additional admin queue (and other) definitions cause the inbound (mqput) message to be delivered to coupling-facility structure that holds the queue image. z/OS queue mangers authorized to participate in queue sharing groups can access the shared queue to get/put messages.
z/OS queue-sharing has noting to do with MQ clustering. z/OS MQ can participate in clusters, as well. |
