<div><p>There are some guidelines that you can follow to improve the performance
|
|
of your copy operations.</p>
|
|
<p>Apart from the guidelines discussed in the proceeding topics,
|
|
when you copy distributed files, you should be familiar with the various factors
|
|
that affect the performance of the copy command. The <span class="keyword">DB2<sup>®</sup> Multisystem</span> feature
|
|
provides support for distributed files, or files that are spread across multiple <span class="keyword">iSeries™</span> servers. When you copy distributed
|
|
files, you should be familiar with the various factors that affect the performance
|
|
of the copy command. You should be aware of restrictions that apply when you
|
|
copy to and from distributed files. For information about copying distributed
|
|
files, see <a href="../dbmult/rzaf3kickoff.htm">DB2 Multisystem</a> .</p>

<li class="ulchildlink"><strong><a href="rbal3ksap.htm">Avoid keyed sequence access paths</a></strong><br />
|
|
A copy that requires maintenance of a keyed sequence access path is slower than a copy from or to an arrival sequence access path.</li>
|
|
<li class="ulchildlink"><strong><a href="rbal3fewparm.htm">Specify fewer parameters</a></strong><br />
|
|
In general, you can improve copy performance if you specify fewer optional copy parameters.</li>
|
|
<li class="ulchildlink"><strong><a href="rbal3identifier.htm">Check record format level identifiers</a></strong><br />
|
|
You can also improve copy performance by correctly setting the record format level identifiers in the CPYF command.</li>
|
|
<li class="ulchildlink"><strong><a href="rbal3preerr.htm">Prevent errors when copying files</a></strong><br />
|
|
You can prevent many copy errors when you plan for certain conditions and situations ahead of time.</li>
