<h2>Spool Performance Considerations</h2>
|
||
|
|
|
||
|
|
<p>As hardware capacity and workloads on the iSeries<sup>(TM)</sup> increase, considerations should be made to ensure performance of spool operations are efficient. For many customers, the operating system enhancements to increase the number of jobs on the system has resulted
|
||
|
|
in additional spooled files. Because of this, lock contention on spool
|
||
|
|
related objects can occur.</p>
|
||
|
|
|
||
|
|
|
||
|
|
<p>This experience report documents information about spool performance considerations.
|
||
|
|
It is intended to help those customers that are experiencing concerns.
|
||
|
|
Specifically, this report will: <ul>
|
||
|
|
<li>Identify spool objects that are most likely to encounter lock contention</li>
|
||
|
|
<li>Provide information about messages that can be expected if performance bottlenecks are encountered
|
||
|
|
<li>Identify several scenarios that can cause spool performance problems</li>
|
||
|
|
<li>Provide recommendations to reduce specific spool performance issues</li>
|
||
|
|
</ul>
|
||
|
|
<p>This report assumes that you are familiar with basic information about
|
||
|
|
spooled files and output queues on the iSeries. You can read more about
|
||
|
|
these topics in the iSeries Information Center at the following link:<ul>
