A Question to "jefflowrey":
Jeff,
in another thread you told it were possible to buy sub-capacity licenses:

Does this mean, I may install MQ on a 4 processor machine and only pay one processor for MQ?
In the same thread Peter Potkay wrote, that binding MQ licenses to single CPUs could save license costs:

1. I would like to bind the mq processes for CPUs on distributed platforms. As csmith28 wrote We pay a lot for MQSeries Liscenses... and we pay by CPUs. Look an example: there is a box with 16 CPUs needed by a heavy-weight application but I can't pay MQ for 16 CPU because the price. For messaging functionality only 2 CPU would be enough.

In the past I had a customer, who used logical partitions on AIX. The customer needed 5 CPUs for the application and wanted to run MQ on another partition with one CPU (to save license costs). This solution was not possible, because the customer needed server binding and was unhappy with client connection (he needed two-phase commit). _________________ Regards

It means, basically, if you have a virtual machine that is only assigned two CPUs, but it's running on a 16way box, then you only pay for 2.
All licensing questions can only be answered by your IBM sales representative. _________________ I am *not* the model of the modern major general. |

That's how I understood licensing, but it would be helpful, to assign MQ to only one CPU on a virtual machine with 5 CPUs - and then pay license only for one CPU.
So this should be added to the Topic Changes I would like to see in WMQ Version X

Is there really a compelling advantage to slicing up processor allocation inside a virtual machine, rather than across virtual machines?
It never seems a good idea to me to give the qmgr a reason to fail or perform badly due to artificial constraints on resources.
I'd much rather allow the Qmgr to shut down the entire box, than crash because it couldn't use an otherwise free CPU. _________________ I am *not* the model of the modern major general. |

Personally I agree , but I have customer, who don't .
It is a question of license costs. Maybe it could make sense, to bind MQ to two or four processors on a 24 processor virtual machine. Than you have failover possibilities but without paying for all 24 processors. _________________ Regards

Counting Software Licenses
Using Specific Virtualization Technologies
A common question we receive from our customers is how do we determine the correct number of processor cores, for a program, given a specific set of virtualization technologies.
To help answer this question we are providing new scenario-based license counting materials to assist you in determining the correct number of processor cores requiring licenses in the following virtualized sub-capacity environments. |

Peter,
let's have a look at the Sun scenario slide no. 4. There is one domain (domain 2) with 8 CPUs where MQ is installed. In this case you have to license these 8 CPUs - ok so far.
Now add an application to this domain. I would like (this means my customer would like ) to bind MQ to two of these CPUs (and only license these two CPUs ) and run the own application on the residual 6 CPUs.
A possibility to save license costs would make most (I guess all) of my customers happy (but maybe not IBM ). _________________ Regards
