| I understand having single queue manager reduces the maintenance. But if I have two different customers ( external to my organization) or different companies, is it a good idea to have two different queue managers to cater to the needs so that I could separate them altogether? Please share your comments/suggestions what your take. |

I would say it depends on the load a single queue manager may experience, whether the processing of messages from one company will affect the performance to an extent that it will negatively impact the other company's traffic being processed, and whether you can be sure of segregating the traffic (DLQ excepted). If you go down the route of separate queue managers you may also want to consider separate servers to house them if one company's queue manager is a resource hog. You haven't really provided sufficient information to suggest either option as being optimal.

If I'm one of your clients, I'd like to ensure that your other clients can't get to my qmgr and its queues. So, I'd require (demand) a single qmgr for me, with SSL-enabled channels.

Perhaps send emails to the two customers, asking them to tell you their requirements. They will know their requirements better than the people on mqseries.net. |

Assuming proper MQ Authority has been set up (big assumption), why would you care if your queues are on the same QM as another company? They can't get at your queues and you can't get at their's on a properly secured QM. If MQ security is poor, it likely you can get at the other queues and they can get at your queues even if they are on separate QMs, assuming a typical interconnected MQ topology.
If you can segregate the QMs onto separate servers and the QMs are not interconnected, that may be an easier way to achieve this goal, albeit more expensive in a few ways.

From discussions here I'm presuming that few may have achieved proper MQ authority.
So, as a paying customer, I'm going to take the conservative position, namely: give me a stand-alone server, give me a qmgr of my own.

We don't create a new qmgr for each external customer/partner, nor would I expect them to do this for me.
I do expect them, however, to have proper security in place. |

I read this as if the OP is a service bureau that offers platforms for others to deploy applications. I did not read this as the client/customer was a supplier or purchaser.

| Thanks for your input. The agreement contained a clause to use industry best practices. So we are good having a single queue manager and yes with proper security to each application. |

hmmm
I can think of many reasons to host one company per QM and LPAR
Mainly maintenance and SLA
Even internally if is difficult to apply Fixpacks/upgrades etc in regards to down time
Customer one fix it now customer 2 nothing wrong with our app
Also do you want someone elses error ie full queue , looping messages to affect more than one customer
many many many things |

There are other discussions here on "which is better: multiple queues on one qmgr? or few queues on multiple qmgrs?"
It depends.
