<h1 class="topictitle1"> Write data and access paths to auxiliary storage</h1>
<div><p> Normally, DB2 Universal Database™ for iSeries™ determines
when to write changed data from main storage to auxiliary storage. However,
you can control when database changes are written to auxiliary storage.</p>
<p>If you want to control when changed data are written from main storage
to auxiliary storage, you can use the force write ratio (FRCRATIO) parameter
on the create, change, or override database file commands, and the force access
path (FRCACCPTH) parameter on the create and change database file commands.
Using the FRCRATIO and FRCACCPTH parameters have performance and recovery
considerations for your system.</p>
