RE: BUFFERS & RA_PAGES
Hi,
Your RA tuning is way out, I suggest applying the formula below. When
you apply this formula to the RA output shown the onstat -p output, the
result is 15% and it should be 0.5 - 2 %. So you need to reduce your RA
configuration. I suspect this will improve the write cache rate as well
since this is about 20% below general recommendations.
}RA TUNING.
}
}(1 + 2 + 3) - 4 = < 2% & > 0.5% of (1 + 2 + 3)
}
}
}1) Add ixda-RA + idx-RA + da-RA (4398 + 29 + 27805 = 32232)
}2) Subtract RA-pgsused from the result
}
} 32232 - 32188 = 44 = 0.14% of 32232
I hope this helps.
Cheers, Tony.
