How activity information is stored

Activity information can be stored in activity reports, trace-route messages, or trace-route reply messages. In all cases the information is stored in exactly the same format; in a structure called the Activity PCF group. A trace-route message or trace-route reply message can contain many Activity PCF groups depending on the number of activities performed on the message. Activity reports contain one Activity PCF group because a separate activity report is generated for every recorded activity. For details of the fields in the Activity PCF group, see Activity report reference.

When using trace-route messaging, additional information can be recorded. This additional information is stored in a structure called the TraceRoute PCF group. The TraceRoute PCF group contains a number of PCF structures that are used to store additional activity information, and to specify options that determine how the trace-route message is handled as it is routed through a queue manager network. For more information on the TraceRoute PCF group, see The TraceRoute PCF group.
