<div><p>You can control when database changes are written to auxiliary
storage using the force write ratio (FRCRATIO) parameter on the create, change,
or override database file command. </p>
<p>Normally, the system determines when to write changed data from main storage
to auxiliary storage. Closing the file (except for a shared close) and the
force-end-of-data operation forces remaining updates, deletions, and additions
to auxiliary storage. If you are journaling the file, the FRCRATIO parameter
should normally be *NONE.</p>
