Thanks Waleed, but I don't quite get your terminology I'm afraid...
When you have three QM in RDQM only one of them is active at any one time - not three. The other two are standby nodes waiting to take over (three are need to cater for that byzantine failure). So I still only have one QM "running" per se. the other two are being indolent teenagers and hovering in the background getting bored for most of the time.
So, with RDQM I am paying for 1 full licence (fine it's running). and 2 HA Replica licences (aka standby licence) (20%) cost i.e. 40% of one full licence.
So if I have a good ol' fashioned multi-instance scenario then I'm saving myself 20% no ? As I have only one indolent teenager in the background at 20% extra cost - not two?
Also: I didn't know that you didn't support RDQM in containers ! That's a real surprise - I could have sworn you used RDQM in the integration pak - do you use multi-instance in that then or perhaps VMs instead of containers? Of course, the point is that I shouldn't care because the licencing should let it come out in the wash. So, what is the licence cost for HA in the pak - 20% more, 40% more - something else?
I guess also, in the integration pak I have no choice about QM placement so I couldn't squeeze multiple QM onto one machine(container or VM) and save myself licence cost - which is what my customers do ?
thanks for your help,
John.

My understanding is that you can have a three node active:active:active RDQM environment supported by one full MQ Advanced license and two HA replica (20% cost) MQ Advanced licenses. So effectively 1.4 licenses for 3 nodes.
Obviously you need to allow some headroom to run 2/3 queue managers on one node in a failure scenario, but the licensing is much more favourable than multi-instance (where HA replica licenses only apply to passive queue managers, and full licenses apply to all active queue managers).
Points to note - no support for RDQM in containers therefore not for use when deploying in containers in ICP4I - but can be used outside. Also RDQM for MQ is not supported currently in use with ACE/IIB - therefore that isn't something to consider.

Thanks for reaching out. I wonder if you can help me with a licencing question around MQ and IIB in the pak...
As far as I understand it RDQM is used as the HA mechanism for MQ - is that right? Therefore, I have at least 3 QM up at any one time (to stop a Byzantine fault). My question is: In terms of licensing, on the face of it this is less efficient than say MQ Multi-instance (only two licences required). Please can you tell me whether I will be charged more for the ability to have HA MQ or have you somehow jigged the ILMT metrics when running in RDQM mode? This is probably my ignorance because I guess I have the same problem if I were to run RDQM outside of the pak too.
I add in IIB because I'm guessing that if you are using RDQM for MQ HA then IIB has to follow?
many thanks.
John.
