As of IBM MQ version 18.104.22.168 (Not on the appliance) we can instead use the mqcertck command. This does the above testing from a previous MQ support pack. The command requires a queue manager is defined but also optionally allows the channel, key repository, port, a specific user or checklabl parameter to be defined and checked.

I began to use this command for my Pure Application MQ and IIB testing to coincide with legacy verification tests used after the success of a deploy.. The first usage gave me the following output based on scripts that had been ported to Pure from legacy stand alone scripts.
