IBM MQ
family of message-oriented middleware products

IBM MQ is a family of message-oriented middleware products that IBM launched in December 1993. It was originally called MQSeries, and was renamed WebSphere MQ in 2002 to join the suite of WebSphere products. In April 2014, it was renamed IBM MQ. The products that are included in the MQ family are IBM MQ, IBM MQ Advanced, IBM MQ Appliance, IBM MQ for z/OS, and IBM MQ on IBM Cloud. IBM MQ also has containerised deployment options.
MQ allows independent and potentially non-concurrent applications on a distributed system to securely communicate with each other, using messages. MQ is available on a large number of platforms (both IBM and non-IBM), including z/OS (mainframe), IBM i, Transaction Processing Facility, UNIX (AIX, HP-UX, Solaris), HP NonStop, OpenVMS, Linux, and Microsoft Windows.
MQ components
The core components of MQ are:
Message: Messages are collections of binary or character (for instance ASCII or EBCDIC) data that have some meaning to a participating program. As in other communication protocols, storage, routing, and delivery information is added to the message before transmission and stripped from the message prior to delivery to the receiving application.
Queue: Message queues are objects that store messages in an application.
Queue Manager: a system service that provides a logical container for the message queue.
Begin with the source’s own compact description: “IBM MQ” is family of message-oriented middleware products. The dossier treats that line as a proposition to test through family, message-oriented and middleware, not as a finished interpretation.
Why this record matters
The phrase “family of message-oriented middleware products” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 2, 2026. The linked authority identifier is Q528294. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1993, 2002 and 2014.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
