<h1 class="topictitle1">System-managed access-path protection</h1>
|
|
<div><p>System-managed access-path protection (SMAPP) provides automatic
|
|
protection for access paths. With SMAPP support, you do not have to use the
|
|
journaling commands, such as the Start Journal Access Path (STRJRNAP) command,
|
|
to get the benefits of access path journaling. </p>
|
|
<p>SMAPP support recovers access paths after an abnormal system end rather
|
|
than rebuilding them during IPL. The shipped system automatically turns on
|
|
SMAPP support. The system sets SMAPP support to a value of 70 minutes.</p>
|
|
<div class="p">The system determines which access paths to protect based on: <ul><li>Target access path recovery times provided by the user, or</li>
|
|
<li>A system-provided default time.</li>
|
|
</ul>
|
|
You specify target access path recovery times as a system-wide value
|
|
or on an auxiliary storage pool (ASP) basis. Access paths already in a user-defined
|
|
journal are ineligible for SMAPP protection because they are already protected. </div>
