Additional activity information
As a trace-route message is routed through a queue manager network, user applications can record additional information by including one or more additional PCF parameters when writing the Activity group to the message data of the trace-route message or activity report.
Additional activity information can help system administrators to identify the route taken by a trace-route message took, or why that route was taken.
If we use the IBM MQ display route application to display the recorded information for a trace-route message, any additional PCF parameters can only be displayed with a numeric identifier, unless the parameter identifier of each parameter is recognized by the IBM MQ display route application. To recognize a parameter identifier, additional information must be recorded using the following PCF parameters. Include these PCF parameters in an appropriate place in the Activity PCF group.
