It's both. You pose a scenario that have users interactively working with
an MQ-based iPhantom. The only reason why that is acceptable is that it is
in fact, an iPhantom charging a license. You will find that you will need
more than one to serve many requests because the response times will not be
desirable when many users are waiting for MQ itself to deliver the messages
from a single U2 MQ iPhantom. More than one would be needed, and each one
costs a license. Indeed, MQ could be viewed as multiplexing type of
technology, but the reality is that it's not practical to use MQ that way.

So, if you use MQ like a connection pool, that is not desirable
performance-wise, and is a breach of your license agreement. But if you use
it for applications to communicate (which is the purpose of MQ), you are
not violating the license agreement. Applications would send messages back
and forth as a result of something a user initiated and wasn't waiting for
an answer.

Leroy,

I don't understand.

First you say:
 >However, remember that if you are using MQ as a
 >means of users communicating with the database in the scenario you
 >describe, you are using MQ as a de facto connection pool and violating
 >your U2 license agreement if you don't have the equivalent number of U2

and then you say:
> Message queues in the user scenario you suggest also does not violate the
> agreement because they consume licenses (as an iPhantom);  users are
> interactively working the U2 database, regardless of the method.

Which is it? if I use MQ series to pass messages to and from my web
application or an atm or whatever to support an application user to
access the database am I neccessarily correctly licensed because the
phantoms are each using a db licence or do I have to worry about the
number of users putting requests on the queue in relation to the number
of phantoms servicing the queue?


thanks,


Craig
