What do you like best about the product?

It is a robust product dominating in the area of Enterprise Messaging providing a variety if APIs for client application integration along with ehnanced mechanisms in message security and integrity, as well as, strong authentication and autohrization capabilities.

What do you dislike about the product?

The overall experience by using IBM MQ is positive. I would prefer more enhancements on message tracking in order to facilitate investigation on cases where messages are lost, jeopardizing transactions integrity especally when client applications are not capable of capturing or logging message delivery or consumption.

What problems is the product solving and how is that benefiting you?

The most severe issues i have faced while using IBM MQ, are related to long running transactions which consume IBM MQ (QM's) transaction log space and lead to transaction hang if not roll back.
The way IBM MQ treats application with long running transactions, leads application vendors (i.e. GPP, ..) to optimize their code resulting to better appliation performance.
Furthermore, IBM MQ (QM) logging mechanism contributes on problem investigation and root cause analysis, applying on several OSI layers such as OS, networking, application, etc.
