<h1 class="topictitle1">Performance considerations for save-while-active</h1>
|
||
|
|
<div><p>While you can run save-while-active operations any time, save-while-active
|
||
|
|
operations will affect the performance of other applications you are running.
|
||
|
|
Therefore you should run save-while active operations during times of low
|
||
|
|
server activity. A few interactive jobs or batch jobs that are primarily read-only,
|
||
|
|
are examples of activities that allow better server performance during the
|
||
|
|
save-while-active operation.</p>
|
||
|
|
<p>In general, the server performs checkpoint processing faster for a small
|
||
|
|
number of larger objects than for a large number of smaller objects.</p>
|
||
|
|
<p>You should not use the save-while-active function when the server is very
|
||
|
|
busy or when there is very little disk storage available. Before you save
|
||
|
|
large amounts of data (such as all user libraries), you should initially use
|
||
|
|
the save-while-active function on a limited amount of data. Using the save-while-active
|
||
|
|
feature on a limited amount of data will help you determine its impact on
|
||
|
|
your server's performance and storage.</p>
