No it does not - but the 'redo log space requests' (imho) is not a good stat for log buffer space sizing, since its common to get this number going up when you switch logs (because briefly everyone is told 'hands off the log buffer').
I prefer the 'log buffer space' wait in v$system_event, v$session_event. Its rare in "typical" systems for a log buffer over (say) 512-1024k to provide any benefit. hth connor --- "Farnsworth, Dave" <[EMAIL PROTECTED]> wrote: > I am doing some performance monitoring on an 8.1.7 > DB on Windoze.
