Performance Considerations of FORCE LOGGING Mode
FORCE LOGGING<wbr> mode results in some performance degradation. If the primary<br> reason for specifying<wbr> FORCE LOGGING<wbr> is to ensure complete media recovery, and<br> there is no standby database active, then consider the following:<br> ■ How many media failures are likely to happen?<br> ■ How serious is the damage if unlogged direct writes cannot be recovered?<br> ■ Is the performance degradation caused by forced logging tolerable?<br> If the database is running in<wbr> NOARCHIVELOG mode, then generally there is no benefit<br> to placing the database in<wbr> FORCE LOGGING<wbr> mode. Media recovery is not possible in<br> NOARCHIVELOG mode, so if you combine it with<wbr> FORCE LOGGING , the result may be<br> performance degradatio n with little benefit </wbr></wbr></wbr></wbr></wbr></wbr></wbr>
