|

|
|
<div><p>The Database Journaling Summary section of the Component
|
||
|
|
report provides information about the journal activity on the system.</p>
|
||
|
|
<p>This information is helpful in understanding the trade-offs between the
|
||
|
|
following:</p>
|
||
|
|
<ul><li>The affects of extensive journaling.</li>
|
||
|
|
<li>The time required to rebuild access paths during an IPL following an abnormal
|
||
|
|
system end.</li>
|
||
|
|
</ul>
|
||
|
|
<p>The Database Journaling section summarizes the journaling activity resulting
|
||
|
|
from user-initiated activities and from system-managed access-path protection
|
||
|
|
(SMAPP) support. This includes the following information:</p>
|
||
|
|
<ul><li>The number of start and stop journaling operations performed.</li>
|
||
|
|
<li>The number of journal entry deposits made on behalf of objects for which
|
||
|
|
a user started journaling.</li>
|
||
|
|
<li>The number of journal entry deposits made on behalf of objects for which
|
||
|
|
the system started journaling.</li>
|
||
|
|
</ul>
|
||
|
|
<p>The Extended Database Journaling Summary subsection shows information about
|
||
|
|
counters in the QAPMJOBMI file during the specified collection interval.</p>
