<h1 class="topictitle1">Performance explorer reports</h1>
|
||
|
|
<div><p>After you have collected performance data with a performance explorer
|
||
|
|
session, you can view it by running the included reports or by querying the
|
||
|
|
database files directly.</p>
|
||
|
|
<p>Performance explorer gathers detailed information about a program or job's
|
||
|
|
behavior and performance and stores this information in performance explorer
|
||
|
|
database files. You can query these files with SQL, or by running one of several
|
||
|
|
reports. You can generate four different reports with performance explorer:
|
||
|
|
Statistics, Profile, Trace, and Base reports. See Performance explorer definitions
|
||
|
|
for information on why you would use a particular definition to generate one
|
||
|
|
of these reports. Each report is discussed in detail in the Performance Tools.</p>
|
||
|
|
<p>You can create and print performance explorer reports by using the <span class="cmdname">Print
|
||
|
|
Performance Explorer Report (PRTPEXRPT)</span> command. Use the OUTFILE
|
||
|
|
parameter when you want to customize your Trace Report. The following commands
|
||
|
|
are examples for printing reports for each type of performance explorer data:</p>
|
||
|
|
<ul><li>Print a *STATS report sorting by the CPU time used <pre>PRTPEXRPT MBR(MYSTATS) LIB(MYLIB) TYPE(*STATS) STATSOPT(*CPU)</pre>
|
||
|
|
</li>
|
||
|
|
<li>Print a profile report summarized by procedure <pre>PRTPEXRPT MBR(MYPROFILE) LIB(MYLIB) TYPE(*PROFILE)
|
||
|
|
PROFILEOPT(*SAMPLECOUNT *PROCEDURE)</pre>
|
||
|
|
</li>
|
||
|
|
<li>Print a trace sorted by task ID <pre>PRTPEXRPT MBR(MYTRACE) LIB(MYLIB) TYPE(*TRACE) TRACEOPT(*TASK</pre>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>Performance explorer stores its collected data in the QAVPETRCI file, which
|
||
|
|
is located in the QPFR library. Type the following command to view the contents
|
||
|
|
for a single record:</p>
|
||
|
|
<pre> DSPFFD FILE(QPFR/QAVPETRCI)</pre>
