<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>
