Does IPC 15.1 have any interaction with MQ 9.3?
However, very few sites use the MQ Transport Service component (i.e.FMID CAVQF16), so if your site does not have this component installed, then you need nothing further.
You can read more about this in the IPC 15.1 documentation section Run the Installation Jobs for a Pax Installation. Also note that the IPC 15.1 README does not mention any issue with MQ.
See also "MQ 9.2 interaction with Datacom/DB and IPC" for additional details about interactions between MQ and Datacom.
