4.7. SYSTRACE, RMFMON, and SDSF
The trace and dump process should be used as a dynamic tool to gather information at the time a problem is occurring.
Comparing the dump time with the time of the last trace entry for a specific ASID can indicate a hang condition if the ASID is not generating any trace entries.
Figure 4-2 shows an example of using IPCS to format the System Trace Table by issuing the SYSTRACE command from the IPCS Subcommand Entry panel. This displays the trace data for ASID that was dumped.
