<h1 class="topictitle1">Performance Data Collector tool</h1>
|
|
<div><p>The Performance Data Collector (PDC) tool provides profile information
|
|
about the programs that run on the iSeries™ server.</p>
|
|
<p>The industry-standard profile option on many Java™ virtual machines depends on the implementation
|
|
of the <samp class="codeph">java_g</samp> feature. This is a special debug version of
|
|
the Java virtual
|
|
machine, which offers the <samp class="codeph">-prof</samp> option. You specify this
|
|
option on a call to a Java program. When you specify this option,
|
|
the Java virtual
|
|
machine produces a record file that contains information about which parts
|
|
of the Java program were operating during the duration of the
|
|
program. The Java virtual machine generates this information in real
|
|
time.</p>
|
|
<p>On the iSeries server,
|
|
the Performance Explorer (PEX) feature analyzes programs and record-specific
|
|
system events. A DB2<sup>®</sup> database stores this information and retrieves it
|
|
using SQL functions. PEX information is the repository for specific program
|
|
information that produces Java profile data. This profile data is
|
|
compatible with <samp class="codeph">java_g -prof</samp> program profile information.
|
|
The <a href="jpdc.htm">Java Performance Data Converter</a> (JPDC)
|
|
tool provides <samp class="codeph">java_g -prof</samp> program output and program profile
|
|
information for a specific IBM<sup>®</sup> tool, which is known as Jinsight.</p>
|
|
<p>For information on how collect Java performance data, see <a href="colpdc.htm">Collect Java performance
|
|
data</a>.</p>
