<h1 class="topictitle1">Dedicated independent disk pools</h1>
|
||
|
|
<div><div class="fignone"><p>In a single-system environment, a dedicated (or stand-alone), independent
|
||
|
|
disk pool can be varied off independent of other disk pools because the data
|
||
|
|
in the independent disk pool is self-contained. That is, all of the necessary
|
||
|
|
system information associated with the independent disk pool's data is contained
|
||
|
|
within the independent disk pool. The independent disk pool can also be varied
|
||
|
|
on while the system is active; that is, no initial program load (IPL) is required.
|
||
|
|
Using independent disk pools this way can be useful, for example, if you
|
||
|
|
have large amounts of data that are not needed for day-to-day business processing.
|
||
|
|
The independent disk pool containing this data can be left varied off until
|
||
|
|
it is needed. When large amounts of storage are routinely kept varied off,
|
||
|
|
you can shorten processing time for operations such as IPL and reclaim storage. </p>
|
||
|
|
<p>In the figure, the user has five independent disk pools. They can represent
|
||
|
|
three different applications where the third application might have archived
|
||
|
|
data. The system automatically creates the system disk pool (referred to
|
||
|
|
as <em>Disk Pool 1</em> or <em>ASP 1</em>), which contains all system programs
|
||
|
|
and system data.</p>
