<h1 class="topictitle1">Find your save window</h1>
|
||
|
|
<div><p>When you run save procedures, how you run save procedures and what
|
||
|
|
you save depend on the size of your save window.</p>
|
||
|
|
<p>Your <span class="uicontrol">save window</span> is the amount of time that your
|
||
|
|
system can be unavailable to users while you perform your save operations.
|
||
|
|
To simplify your recovery, you need to save when your system is at a known
|
||
|
|
point and your data is not changing.</p>
|
||
|
|
<p>When you select a save strategy, you should balance what your users think
|
||
|
|
is an acceptable save window with the value of the data that you might lose
|
||
|
|
and the amount of time it might take to recover.</p>
|
||
|
|
<p>If your system is so critical to your business that you do not have a manageable
|
||
|
|
save window, you probably cannot afford an unscheduled outage either. You
|
||
|
|
should seriously evaluate all the availability options of the <span class="keyword">iSeries™</span> server,
|
||
|
|
including clusters. The Availability roadmap for your iSeries server topic has more information
|
||
|
|
about availability options.</p>
|
||
|
|
<p>Based on the size of your save window, choose one of the following save
|
||
|
|
strategies: simple, medium, or complex save strategy. Then reevaluate your
|
||
|
|
decision based on how your save strategy positions you for a recovery.</p>

|

|
<li class="ulchildlink"><strong><a href="rzaj1simplestrat.htm">Simple save strategy</a></strong><br />
|
||
|
|
You have a long save window, which means that you have an 8- to 12-hour block of time available daily with no system activity (including batch work). The simplest save strategy is to save everything every night or during off-shift hours.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzaj1mediumstrat.htm">Medium save strategy</a></strong><br />
|
||
|
|
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.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzaj1complexstrat.htm">Complex save strategy</a></strong><br />
|
||
|
|
You have a short save window, which means that there is little or no time when your system is not being used for interactive or batch work. A very short save window requires a complex strategy for saving and for recovery.</li>
