Ouch! :)
Rachel,
It's not a case of me looking for problems. I was surprised to find this occuring so maybe doing something about it would improve the system alittle. I am looking into the redo log performance because I am unsure that the redo log switches are normal as they can be very high during office hrs as high as 60 switches in an hr, but having said that the switches avrg out at 3-4 switches an hour. So all the obvious are to be looked into ie checkpoints etc.
From your line of thought in the email below, I am reading into it that you don't find this to be an issue, which is great. I will then just carry on checking all the other possible parameters and stats, until I am happy that the redo logs are as healthy as they can be.
In my defence I did try the to change the parameter on my test system first.
Hope that explains my line of thought and modus operandi.
Regards
Denham

there is a point at which you begin to tune for the sake of tuning and
not because you are relieving a problem.
if you are not getting reports of performance problems, why are you
trying to fix it? the old adage "if it ain't broke, don't fix it"
applies here.
