<h1 class="topictitle1">Size of the physical file member</h1>
|
||
<div><p>The SIZE parameter specifies the maximum number of records that
|
||
can be placed in each member (CRTPF, CHGPF, CRTSRCPF, AND CHGSRCPF commands).</p>
|
||
<p>The following formula can be used to determine the maximum:</p>
|
||
<p>R + (I * N)</p>
|
||
<div class="p">where:<dl><dt class="dlterm">R</dt>
|
||
<dd>is the starting record count</dd>
|
||
<dt class="dlterm">I</dt>
|
||
<dd>is the number of records (increment) to add each time</dd>
|
||
<dt class="dlterm">N</dt>
|
||
<dd>is the number of times to add the increment</dd>
|
||
</dl>
|
||
</div>
|
||
<div class="p">The defaults for the SIZE parameter are:<dl><dt class="dlterm">R</dt>
|
||
<dd>10 000</dd>
|
||
<dt class="dlterm">I</dt>
|
||
<dd>1000</dd>
|
||
<dt class="dlterm">N</dt>
|
||
<dd>3 (CRTPF command)</dd>
|
||
<dt class="dlterm"></dt>
|
||
<dd>499 (CRTSRCPF command)</dd>
|
||
</dl>
|
||
</div>
|
||
<p>For example, assume that R is a file created for 5000 records plus 3 increments
|
||
of 1000 records each. The system can add 1000 to the initial record count
|
||
of 5000 three times to make the total maximum 8000. When the
|
||
total maximum is reached, the system operator either stops the job or tells
|
||
the system to add another increment of records and continue. When increments
|
||
are added, a message is sent to the system history log. When the file is extended
|
||
beyond its maximum size, the minimum extension is 10% of the current size,
|
||
even if this is larger than the specified increment. Instead of taking the
|
||
default size or specifying a size, you can specify *NOMAX. </p>
