<h1 class="topictitle1">Medium save strategy</h1>
|
||
|
|
<div><p>You have a medium save window, which means that you have a 4- to
|
||
|
|
6-hour block of time available daily with no system activity. Use this strategy
|
||
|
|
if you find that you do not have a long-enough save window to use a simple
|
||
|
|
save strategy.</p>
|
||
|
|
<p>Perhaps you run large batch jobs on your system at night. Or, you have
|
||
|
|
very large files that take a long time to save. If this is the case, you
|
||
|
|
might need to develop a medium save strategy, which means that the complexity
|
||
|
|
for saving and for recovery is medium.</p>
|
||
|
|
<p>When developing a medium save strategy, apply this principle: the more
|
||
|
|
often it changes, the more often you should save it. You just need to be
|
||
|
|
more detailed in evaluating how often things change than when you use a simple
|
||
|
|
strategy.</p>
|
||
|
|
<p>Several techniques are available to use in a medium save strategy. You
|
||
|
|
can use one of them or a combination:</p>
|
||
|
|
<ul><li>Save changed objects.</li>
|
||
|
|
<li>Journal objects and save the journal receivers.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div>
|
||
|
|
<ul class="ullinks">
|
||
|
|
<li class="ulchildlink"><strong><a href="rzaj1chgobj.htm">Save changed objects</a></strong><br />
|
||
|
|
You can use several commands to save only information that has changed since the last save operation or since a particular date and time.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzaj1jrnldb.htm">Journal objects and save journal receivers</a></strong><br />
|
||
|
|
If your save operations for database files take too long because your files are large, saving changed objects might not help you.</li>
|
||
|
|
</ul>
