Hi,

We are delving into the world of queue sharing and clustering and I have a couple of questions...

1. We have a requirement for queue sharing on our z/OS queue managers and clustering the z/OS queue managers with other queue managers on Sun Solaris servers. Would it be better to implement clustering before queue sharing, queue sharing before clustering or doesn't matter?

2. I have been reading the documentation on group ports and am wondering whether it might meet some of our clustering requirements. We have an application running on NT accessing a single NT queue manager that sends MQ messages to an application on z/OS. The z/OS application runs on multiple LPAR's accessing multiple queue managers. From the documentation it appears if we implement queue sharing and use group ports the NT application messages would be sent to any of the queue managers in the queue sharing group. It doesn't appear that the messages would be load balanced but since the z/OS queue is shared, the messages would be available to the applications running on the different LPAR's. Could this be used as a poor man's clustering? Are there any drawbacks to doing this?

Thanks
Shannon
