During a very intense checkpoint (after lots of changes) iostat shows rbs
volume going nuts for a long time then just a blip on the datafiles. I know
that datafile headers are frozen so I assume changed blocks during
checkpoint would be written to rbs but thier doesn't seem to be that much
activity in the db when I am doing this. If only new changes are being
written to the rbs what is the long delay in the write to the datafiles?
One more thought, the changes actually pretty much zero out (i.e. insert
then delete) so this might be the reason so little is actually written to
the datafile.
Thanks,
Ethan
