<div><p>The storage pool size specified for a subsystem affects the performance
|

and number of threads you can create.</p>
|
|
<div class="section"><p>If thread creation or processing is slow or fails consistently
|
|
with an out-of-memory error, you might not have enough resources available
|
|
in the storage pool to run all of your application threads in addition to
|
|
the other jobs that are using the same storage pool. Increasing the storage
|
|
pool size might eliminate these problems. </p>
|
|
</div>
|
|
<div class="section"><p>You can examine the storage pool sizes by using the <span class="cmdname">Work
|
|
with System Status (WRKSYSSTS)</span> command. If you have too many active
|
|
threads or threads that use too many system resources, you will see numerous
|
|
page faults for the storage pools in which applications are running. Increasing
|
|
the storage pool size might reduce the number of page faults. </p>
