<h1 class="topictitle1">Local and remote committable resources</h1>
|

|
|
<div><p>A committable resource can be either a local resource or a remote
|
||
|
|
resource.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Local committable resource</h4><p>A local committable resource
|
||
|
|
is on the same system as the application. Each journal associated with resources
|
||
|
|
under commitment control can be thought of as a local location. All the resources
|
||
|
|
that are registered without a journal (optionally for both DDL resources and
|
||
|
|
API resources) can be thought of as a separate local location.</p>
|
||
|
|
<p>If a
|
||
|
|
committable resource is on an independent disk pool, the resource is not considered
|
||
|
|
local if the commitment definition is on a different disk pool.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Remote committable resources</h4><p>A remote committable
|
||
|
|
resource is on a different system from the application. A remote location
|
||
|
|
exists for each unique conversation to a remote system. A commitment definition
|
||
|
|
might have one or more remote locations on one or more remote systems.</p>
|
||
|
|
<p>When
|
||
|
|
you place a local resource under commitment control for the system disk pool,
|
||
|
|
or any independent disk pool, you must use DRDA<sup>®</sup> to access resources under commitment
|
||
|
|
control in any other independent disk pool.</p>

||
|
