Application activity trace

Application activity trace produces detailed information about the behavior of applications that are connected to a queue manager.

Application activity trace traces the behavior of an application and provides a detailed view of the parameters that are used by an application as it interacts with IBM® MQ resources. It also shows the sequence of MQI calls issued by an application.

The IBM MQ Appliance supports the IBM MQ V9 methods of collecting application activity trace data, with the important exception that you cannot configure the collection of data by directly editing the mqat.ini configuration file. See Application activity trace in the IBM MQ documentation for details of collecting and reading application activity trace data. The methods write activity trace PCF messages to the system queue SYSTEM.ADMIN.TRACE.ACTIVITY.QUEUE.

In addition to writing trace data to the system queue, the IBM MQ Appliance introduces a new method of subscribing to activity trace data written to special IBM MQ system topics. This method is described in the following topics.

Note that the IBM MQ Appliance does not support the use of exits. If you have previously used exits to trace application activity, you must switch to using application activity trace.
