How activity information is recorded

When using trace-route messaging, activity information can be recorded using either, or both, of the following techniques:

Accumulating activity information in the message data of the trace-route message

As a trace-route message is routed through a queue manager network, information about the activities performed on behalf of the trace-route message can be accumulated in the message data of the trace-route message. The activity information is stored in Activity PCF groups, see How activity information is stored. For every activity performed on behalf of the trace-route message, an Activity PCF group is written to the end of the PCF block in the message data of the trace-route message.

Additional activity information is recorded in trace-route messaging, in a PCF group called the TraceRoute PCF group. The additional activity information is stored in this PCF group, and can be used to help determine the sequence of recorded activities. For information on the parameters contained in the TraceRoute PCF group, see The TraceRoute PCF group.

This technique is controlled by the Accumulate parameter in the TraceRoute PCF group, see ***.

Recording activity information using activity reports

As a trace-route message is routed through a queue manager network, an activity report can be generated for every activity that was performed on behalf of the trace-route message. The activity information is stored in the Activity PCF group, see How activity information is stored. For every activity performed on behalf of a trace-route message, an activity report is generated containing an Activity PCF group. Activity recording for trace-route messages works in the same way as for any other message. For more information on activity recording, see Activity recording.

Activity reports generated for trace-routes messages contain additional activity information compared to the those generated for any other message. The additional information is returned in a TraceRoute PCF group. The information contained in the TraceRoute PCF group is only accurate from the time the activity report was generated. The additional information can be used to help determine the sequence of activities performed on behalf of the trace-route message. For information on the parameters contained in the TraceRoute PCF group, see The TraceRoute PCF group.
