IMS and WebSphere MQ

IMS programs explicitly connect to, and disconnect from, WebSphere MQ using the MQCONN and MQDISC APIs, and require no configuration.

However, if you wish to use triggering and have WebSphere MQ participate as a resource manager, then you need to define an XA resource switch module and a WebSphere MQ listener.

An older method of triggering using JES and a PSB for the trigger monitor is still supported, but is now deprecated. Micro Focus recommends that you use the new method.
