<h1 class="topictitle1">Temporary result writer job: Advantages with DB2<sup>®</sup> Multisystem</h1>
|
||
|
|
<div><p>The advantage of using a temporary result writer job in processing
|
||
|
|
a request is that the temporary result writer can process its request at the
|
||
|
|
same time (in parallel) that the main job is processing another step of the
|
||
|
|
query.</p>
|
||
|
|
<p>Performance advantages of using a temporary result writer are as follows:</p>
|
||
|
|
<ul><li>The temporary result writer can use full symmetric multiprocessing (SMP)
|
||
|
|
parallel support in completing its query step, while the main job can continue
|
||
|
|
with more complex steps that do not lend themselves as easily to parallel
|
||
|
|
processing (such as query optimization, index analysis, and so on).</li>
|
||
|
|
<li>Because distributed file processing requires communications interaction,
|
||
|
|
a considerable amount of time typically spent waiting for sending and receiving
|
||
|
|
can be offloaded to the temporary result writer, which leaves the main job
|
||
|
|
to do other work.</li>

||
