<div><p>Managing performance on <span class="keyword">iSeries™</span> systems
|
||
|
|
requires the use of a variety of specialized applications. Each of these applications
|
||
|
|
offers a specific insight into system performance. This topic explains several
|
||
|
|
applications and the intended use of each application.</p>
|
||
|
|
<div class="section"><p>Many of the applications for performance management have several
|
||
|
|
functions. Knowing exactly which component of the available suite of applications
|
||
|
|
best suits a given situation can be complex. The following topics provide
|
||
|
|
detailed information about each of the performance management applications,
|
||
|
|
including selection, use, and configuration.</p>
|
||
|
|
<p>As shown in the following
|
||
|
|
figure, basically there are two performance collection functions on the <span class="keyword">iSeries</span> servers:</p>
|
||
|
|
<ul><li>Collection Services, which collects interval data at the system and job
|
||
|
|
level. You can run this continuously to know what is happening with your system.
|
||
|
|
The interval data that is collected is either application defined or user
|
||
|
|
defined.</li>
|
||
|
|
<li>Performance explorer, which collects detailed data at the program and
|
||
|
|
application level. It also traces the flow of work in an application and can
|
||
|
|
be used to diagnose difficult performance problems. The data that is collected
|
||
|
|
is by application-defined performance explorer trace points, such as with Domino<sup>®</sup>, NetServer™,
|
||
|
|
or WebSphere<sup>®</sup>.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Both collection functions deposit their data into management collection
|
||
|
|
objects. You can convert the data from the management collection objects by
|
||
|
|
using the Create Performance Data (CRTPFRDTA) command for Collection Services
|
||
|
|
data or by using the Create Performance Explorer Data (CRTPEXDTA) command
|
||
|
|
for the performance explorer data.</p>
|
||
|
|
<p>This topic introduces the performance
|
||
|
|
management applications that are available to work with either the Collection
|
||
|
|
Services data or the performance explorer data.</p>
