<p>The Start Performance Trace (STRPFRTRC) command is a simplified interface to the TRCINT command for collecting Multiprogramming level (MPL) and Transaction trace data. This command collects the same performance trace data as was collected in previous releases by the Start Performance Monitor (STRPFRMON) command.
|
||
|
|
</p>
|
||
|
|
<p>The trace started by this command creates and uses trace table QPM_STRPFRTRC.If the trace table exists, any existing data will be deleted before this trace begins.
|
||
|
|
</p>
|
||
|
|
<p>The trace can be stopped and the data can be written to a data base file by using the End Performance Trace (ENDPFRTRC) command.
