I have 1 QMGR on 1 server with 1 IP address with 1 QL....simple.
They have 2 servers each having one QMGR. (SVR1 with QMGR1 and SVR2 with QMGR2) NO clustering software, no load balancing hardware, nothing.
On each of these servers there are 4 network cards, 4 IP addresses. (8 total)
I think a listener will be configured for each IP. (again 8 total)
There is only 1 QL set up in each of the QMGRs named QL1.
I am not sure how to configure MQ with all the IP's at the other end. I am assuming (for now) that their application is set up to look at QL1 on SVR1 and QL1 on SVR2.
I guess I need a SDR channel for each of the 8 IP's. Which means I need 8 xmit queue's and 8 QR's.
I have only worked with MQ for 1 month so I am a NOOB. |

You need a SDR channel for each of the IPs that a) a listener is configured for and b) you actually plan to use.

| will I also have 8 QR's and 8 xmit queues? Even though I am really only pointing to 2 QL on their end? |

Or you could cluster them, but I wouldn't recommend that with only 2 queue managers and 1 month's experience quite frankly!
(No offence intended, but it's a complex piece of work that can be error prone and for a 2 queue manager cluster I doubt the cost/risk/benefit case is justifiable).
But I mention it as an option.

It depends how many of these addresses you plan to use. All you need is a route source->target so as long as there's at least 1 usable channel on one of the IP addresses (with associated xmitq) then all the traffic can flow down that.
The questions are:
1) How many IP addresses are you using?
2) Why are you using more than one (differentiated traffic for instance)?

Or to answer the question another way - each sender channel will require it's own xmitq.
How many remote queues you have is a separate design question.

| The 2 QMGR, 8 IP setup is at a client site. i don't have control over them,but have suggested MQ clustering, IP load balancing, etc. They won't do anything of the kind. They want 2 servers, each with 4 IP's, with only 1 QMGR and 1 QL on each. |

I only have 1 IP. I am not sure of their intentions beyond making things more complex. For our application, we only need 1 QR. But since they have so many listeners, I am not sure how to do that. In my mind, I have to configure a QR for each xmit q going down each channel, all ending up at one of two QL's on their end. It would then be up to some type of manual configuration on the application side to point to one of the 8 possibilities.
Oh well...this is a huge design issue and I got what I initially needed. I will need 8 channels for their 8 listeners. |

Then you're in clover. Ask your client which IP address they intend the queue manager to use in each case, set up for that address and sit back.
If they want all 4 addresses used, ask under what circumstances traffic is directed to what address, and define queue remotes to deal with that.
Simple, clear, wonderful.

The biggest problem will be for your application trying to work out which queue remote or remote queue manager name to refer to when doing the put. This will make your one-time cost of setting up 8 almost identical channels seem as nothing....
