<h1 class="topictitle1">Performance data files: Collection Services system category and file
relationships</h1>
<div><p>When you collect performance data using Collection Services, the
data is stored in a management collection (*MGTCOL) object.</p>
<div class="section"><p>The <span class="cmdname">Create Performance Data (CRTPFRDTA)</span> command
exports data from that management collection object and then writes the data
to the performance data files. Each type of data that can be independently
controlled and collected by <a href="rzahxcollectdatacs.htm">Collection
Service</a> is represented by a data category. Each data category contains
or provides data that is written to one or more performance data files. For
a database file or member to be created, the category (or group of categories)
that the file or member is dependent on must exist and be processed by CRTPFRDTA.
The table below identifies the category-to-file relationships. There are three
types of relationships:</p>
<div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="border" border="1" rules="all"><thead align="left"><tr><th valign="top" class="firstcol" id="d0e63">Relationship</th>
<th valign="top" id="d0e65">Description</th>
</tr>
</thead>
<tbody><tr><th valign="top" class="firstcol" id="d0e69" headers="d0e63 ">Primary files</th>
<td valign="top" headers="d0e69 d0e65 ">These files are related to and generated from the category.</td>
</tr>
<tr><th valign="top" class="firstcol" id="d0e74" headers="d0e63 ">Compatibility files</th>
<td valign="top" headers="d0e74 d0e65 ">These files are logical files that join primary files to provide performance
database compatibility with the previous file structure. If the system generates
all participating files (primary categories), compatibility files are also
generated.</td>
</tr>
<tr><th valign="top" class="firstcol" id="d0e79" headers="d0e63 ">Secondary files</th>
<td valign="top" headers="d0e79 d0e65 ">These files are related to and contain some data that is derived from
data contained in the category or in the primary file. However, they are not
controlled by that category.</td>
</tr>
</tbody>
</table>
</div>
<p>Users should note the following:</p>
<ol><li>The CRTPFRDTA command generates a database file only when that file is
a primary file for the selected category.</li>
<li>If a primary file is listed for multiple categories, you must select each
of those categories to generate the file.</li>
<li>If a primary file for one category is listed as a secondary file for another
category, you must select the second category to ensure complete information
in your generated database file. For example, as shown in the table below,
to generate a complete database file for QAPMECL, you must select both *CMNBASE
and *CMNSTN.</li>
<li>The system generates compatibility files only when it generates all associated
primary files.</li>
</ol>
<p>The table below illustrates the relationships between system categories
and performance database files.</p>
